    Introduction

    Every year thousands of kilometres of tunnel are lined with precast concrete segmental tunnel linings. Success of these tunnel projects depends on the linings being safe and easy to construct, watertight, and able to resist loads from ground and water, as well as the loads imposed by the Tunnel Boring Machine (TBM). Being precast elements, there is no opportunity to change the design once construction begins, so all these elements have to be carefully designed into the lining from the outset.

    As well as an understanding of all permanent load conditions, good design requires an understanding of the TBM, contractors’ expertise and preferences, segment manufacturing process, storage, and handling. When designing for these conditions the designer must also ensure that all fixtures and fittings used to aid the erection of a robust linings – such as bolts, dowels, and gaskets – are sufficient to fulfil their role over the expected range of construction and operating conditions.

    Objectives

    This course is designed to give students an understanding of the basic concepts of the design of precast segmental tunnel linings, covering all the above areas, including:

    • Manufacture
    • Storage and transportation
    • Erection in the tail shield of the TBM
    • TBM advance, ram loads, and grouting
    • Permanent loads
    • Ring design
    • Joint design
    • Bolt and gasket design

    At the end of the course, students will have sufficient knowledge to undertake a simple segmental lining design, or to engage in more complex designs under the direction of more experienced designers. They will also be aware of some of the common errors in design that can result in poor performance that often leads to problems building, damage, and loss of waterproofing, as well as how to avoid them.

    The tutoring system is managed by email. Students can email the tutor with any questions about the course and the tutor will be happy to help.

    This course is aimed at civil or geotechnical engineers. A basic understanding of geotechnical theory (including the difference between effective and total stresses) and structural mechanics (bending moments, axial forces, shear forces) is essential, but more complex concepts will be briefly explained with references to additional material to allow students to obtain a deeper understanding if desired.

    Once a student finishes the course and successfully completes the assignments and evaluation tests, they are sent an accreditation certificate. The certificate is issued by Ingeoexpert to verify that the student has passed the course. It is a digital certificate that is unique and tamper-proof – it is protected by Blockchain technology.

    You will be able to download the certificate in an electronic format from the Virtual Campus platform. The certificate can be forwarded by email, shared on social networks, and embedded on websites. To see an example, click here.

    Given the volume of tunnel constructed using TBMs and precast concrete segmental linings, segmental lining design is one of the key skills that a well rounded tunnel engineer should master. This course provides the essential knowledge for budding tunnel designers, as well as design mangers and project managers looking to understand the issues that their designers must solve.
