    Introduction

    One of the most important tasks of a tunneling/mining professional is to develop construction and ground support methods that achieve safe underground excavations. Safety must be guaranteed not only throughout the design life of the structure (long-term) but also during construction (short-term). To successfully complete this task, engineers must have, as a minimum, basic knowledge of the design principles associated with ground support. The purpose of this course is to provide the learner with easy-to-understand introductions to some of the knowledge required to design ground support for tunnels in rock.

    Firstly, it is essential to understand what failure mechanisms need to be addressed via design. In rock tunnels, these failure mechanisms are different than those observed in soft ground tunneling and soil mechanics due to the discontinuous nature of rock masses. One must consider and understand the inherent inter-relation between these failure mechanisms and the three basic ground support principles in rock tunneling: (a) suspension, (b) reinforcement and (c) surface retention. Secondly, the designer must also understand the inter-relationship between these failure mechanisms and construction methods. For example, the same ground support could be either safe or unsafe depending on the time of its installation (advance and support sequence) or if the tunnel has been excavated in full face or multiple headings (excavation sequence). Another example is the method of excavation and its associated impacts on ground support performance. For example, mechanized excavation methods such as roadheaders are much less likely to disturb the rock mass around the excavation opening than in drill and blast operations which certainly improve the performance of both reinforcing and surface retention elements (e.g. rockbolts and sprayed concrete linings)

    Last, but not least, engineers must understand the most fundamental difference between the concepts used in the design of ground support and those used in the design of other structures, such as bridges or buildings, particularly when using a Load and Resistance Factor Design (LRFD) approach. The main component that loads a tunnel support is the ground or rock mass which also provides resistance. In other words, load and resistance are interdependent. With some exceptions, this also means that the design of ground support is inherently associated with displacement-controlled failure mechanisms where loads are not constant but a function of deformation. This also explain why some yielding is acceptable in ground engineering whereas it is avoided in other fields of engineering where failure mechanisms are load-controlled, e.g. the structural design of bridges.

    Objectives

    By the end of this course, you will have the needed background and basic knowledge to understand:

    • The typical failure mechanisms in rock tunnels and how to address them
    • The inter-dependency between loads and resistance and its impact on design
    • The basic ground support design principles in rock tunneling: (a) suspension, (b) reinforcement and (c) surface retention.
    • The detailed design of rockbolts and sprayed concrete linings
    • The impact of construction methods and excavation sequence

    All subjects will be explained with easy to understand examples. Lessons will mainly focus on practical aspects of actual designs such that the contents of this course cannot be found in a single textbook. Where applicable and possible, design tools in the form of spreadsheets and trial period of useful programs will also be provided.


    Full-featured versions of Unwedge and RS2 software included: to put the theory into practice, the course also includes the use of two Rocscience programs: Unwedge and RS2. Practical tutorials and exercises are used to illustrate the application of rockbolts and sprayed concrete lining in the design of ground support in the same way as used in real industry practice

    Underground structures are one of the best solutions for urban problems and for interurban links in mountainous landscape. A wide range of underground structures are continuously needed to improve living conditions in cities. Tunnels for transportation (motorways, metros) and for public utilities (water supply, sewerage, electrical and telephone cables) are a priority in most developing countries, and underground structures for city center revitalization and for public use (libraries, museums, car parking, entertainment and leisure facilities) are of great interest in developed countries.

    Whatever the type of underground structures in an urban environment, they all aim to free surface space for more noble human needs, improving the living conditions of our cities. In the case of interurban links, long-length tunnels are justified by saving time and reducing costs (shorter journeys and less energy consumption), maximizing safety and minimizing environmental impacts.

    1. Rasmus Bjoerkman

      This course helped me immensely on how to adopt different approaches, fundamental principles and common rock engineering tools compared to how I’m used to adopt these. Most of my background is from Stockholm(Hard crystalline rock environment) and being put in a completely new geological environment here in Sydney(Sedimentary rock environment) has been challenging. The basic principles are the same but being provided key papers and having crucial tweaks to theories explained to you in person make all the difference.

      I’m now in a much better position to proceed my career as a Tunnel Engineer in Australia.

      Thank you David!

    2. Sina

      David is an excellent instructor and researcher. What I most appreciate about him is his different thinking method about the tunnel/rock mechanics problems. He has always something new to teach/discuss. I really enjoyed this online course and would definitely participate in other more advanced geotechniocal/tunnel courses proposed by him in the future.
      Thank you so much David

    3. Alex

      I highly recommend Dr. Oliveira`s course. The course modules are explained in detail and all aspects of tunnelling design are covered, including cutting edge case studies and numerical modelling.
      Dr. Oliveira is highly skilled in numerical modelling and other design software (such as the ones developed by Rocscience Inc.) which have been used to carry out course related design. Answers and explanations have been provided to all questions.

    4. Yucânia Da Cruz

      Just like the rest of the class said, David is an excellent instructor.
      Being a engineer geologist with a short experience in tunneling surveillance, the course helped me to gain a geotechnical knowledge and to understand the geotechnical side during design phase.
      David made an extraordinary work to make us understanding the importance of numerical modeling while providing us practical/realistic cases.
      Thank you!

    5. Wei She

      Great course by master David. Highly recommend.

    6. Desmond Vlietstra

      This course has an excellent balance of background, theory and practical information and is extremely well presented I would highly recommend this course, regardless of your level of knowledge there is something here for anyone from young graduates to long practicing practitioners and anyone in between.

      David is an outstanding presenter and happy to share his immense knowledge.

    7. Howard Toi

      Excellent course delivered by David for both students and tunnel professionals to improve their knowledges on tunneling in rock. The course covers fundamentals, some latest development in tunneling, numerical modelling and very useful industry practices. I would highly recommend anyone who is interested in tunneling.

    8. Esteban Litvin

      Great course and better instructor!!! Very practical course covering all aspects from fundamental rock mechanics all the way to tunnel construction methodologies.

    9. Bruno Ferraz

      Indispensable learning for everyone involved in this market, our teacher Dr. David successfully managed to gather in a few hours a large volume of important information that is already making a difference in my day.

      Thank you David and thank you Ingeoexpert for this opportunity.

    10. Ahmet Sefa Ozer

    11. Priscila Ferraz

      Amazing course, especially for me, new on this industry. I’ve learned a lot with Dr. David and his support during all course was essential for my learning! Thank you David!

    12. Anna Zuin

      It was a pleasure to take part to the course. I have learned so much from it and it gives me the opportunity to improve my knowledge in tunnelling that, until now, was only academic. I highly recommend it because it deals with practical aspects of excavation.

    13. VALERIO GIORDANO

      I signed up for this online course because I wanted to deepen my knwoledges in tunnelling especially from the practical and designing side.
      There are no many courses which covering this fascinating topic (except the full time Masters with a typical one year duration), and most of them are much theoretical. But this one did not dissappoint my expecations. The lecturer, David, shared with us all his expertise and know how, and this was magnificent because he is a “egnineer on field”, so he could share his direct experience with us as well.
      Practical cases of ground support, technical insights on rock bolting (that for me has been very precious), rock classifications, lining design, tutorials on how to use FEM softwares, etc. have been faced.
      Therefore, this is a really well done course for all those who wants to approach to tunnelling world.

    14. Michele Camin

      Very interesting, useful and pragmatic course. Professor David is very expert and to show it during the video lessons and the webinars. Highly recommend.

    15. Harry Asche

      Excellent and detailed course. I would highly recommend it. The course demonstrates David’s knowledge, patience and generosity.

    16. Jacek Rachocki

      Excellent course delivered by a very passionate and extremely knowledgeable tunnel engineer. Course has been prepared to the highest standard with theory and practice being linked extremely well. I can highly reccomend it to engineers involved in the tunnelling industry.

      This is a brilliant course thanks to David for his enthusiastic, active and superior leadership. The course is an excellent combination between fundamental background of rock mechanics and practical applications in tunnels. I have transformed myself from zero of rock tunneling to a certain degree of confidence in this field. David has a fabulous knowledge and experience in tunneling, but more importantly, he is very passionate and willing to share with learners through various exercises and discussions. Furthermore, David truly understands how busy we are nowadays, and he has made a great approach to optimize the learning curve.

      Again thanks David for giving and leading this course.

    18. Ramtin Tajeddin

      Highly recommended. David is very knowledgeable, good instructor, well organized and generous in sharing his knowledge.

    19. ALI K E N E T I

      It is a great course concisely summarizing basic design concepts required for tunneling in hard rocks. David is a well-known expert in practical rock engineering, a well resourced teacher who perfectly delivers this course in a friendly atmosphere, and an approachable professional for any questions you might have. I recommend this course particularly to people with rock mechanics background to shape their knowledge and enhance their understanding of different aspects of tunneling. For those with less exposure to geomechanical designs or theories, this course certainly exposes you to wide range of topics you might explore further using the complementary references provided by David.

    20. Gustavo Ranalli

      This is an excellent course, with right balance between theoretical and practical subjects. I have found it very well arranged, with a focus on all those issues that matter at design and construction stage. The lessons are very clear and the support in terms of tools, softwares, and relevant papers is good and useful for the scope. Dr. David Olivera is an excellent teacher and an experienced professional. He is always available, his lessons are interesting, and the regular webinars are a good opportunity for the attendees to go deeper in some topics or to discuss some key issues of the exercises. Highly recommended.

    21. Arya Predana

      Amazing course with exceptional learning materials. Dr. David Oliveira is successfully providing both theory and practical things on site which is important to have deeper understanding on tunneling specifically in rocks. As a postgraduate student who is keen to learn more on tunneling, this course really helps me to explore more on this particular topic. Well done and highly recommended!

    22. Sani Ibric

      The entire course was a wonderful experience, very well structured with valuable learning outcomes for a broad range of engineering audiences. David as a presenter is very dedicated and always able to make complex subject matter easy understandable for everyone involved. His decades of experience as a tunnel designer (both from a design and practical perspective) are well implemented throughout the entire course providing a great learning outcome and a valuable take away for everyone involved. Very well done, thanks David.

    23. Ahsan Tahir

      This course has been great for my learning as it has helped me gain understanding of some of the tunneling concepts for ground support in rock.

    24. Simon Yau

      This training course has exceeded my original expectations where I found it informative and useful. The course (in five modules) was well structured starting from a basic introduction to deeper end of tunnel engineering encompassing both design and construction issues. Thank you David!

    25. Pawel Kozak

      An amazing course where experienced tunnel engineers can refresh their memory or, as was the case in my case, join all the dots, which I thought I understood but not necessarily in the right context. David, who is very passionate about tunneling, covers a wide range of topics related to tunneling in rock and at varying difficulty levels so everyone, from a graduate or a student indeed, to an experienced tunneller will find something for themselves. The live seminars are invaluable as you can ask David your own questions, whether they are related to the written assignments or not. After the course, you will able able to keep David’s presentations with enough information in them to write a tunnel design book.

    26. Adrian Tola

      I have been working in the tunnel field for a while and finally found a course that has an excellent combination of rock mechanic theory, numerical modelling, and practical applications. The modules are organized in a practical way and explain in detail the essential aspects of tunnelling design.
      Dr David Oliveira is enthusiastic and dedicated to make all subjects understandable. The webinars are a great opportunity to discuss topics and clarify concepts addressed during the course and also learning from his experience. Thank you David for making this course possible and leading it with mastery!
