Engineering on rock slopes has been a debatable topic for years partly due to the limited number of rock engineers in the civil/ geotechnical engineering industry and the lack of agreed and consistent standards and design codes.
The behavior of rock masses during slope excavation, in some limited instances, can be similar and described in soil mechanics terms (highly disturbed material, heavily jointed very weak rocks, etc.). Consequently, limit equilibrium and finite element numerical modelling is regularly utilized in order to assess slope stability and eventually inform the design. However, depending on the ground conditions and material type, the rock mass behavior can be proven completely different from what was assumed. One of the main reasons for this, is the existence of discontinuities within the rock mass.
In UDEC, which is a software based on the Finite Difference Method (FDM), the user can model sets or individual discontinuities, allowing the rock blocks to move along these planes. Consequently, the analysis can capture slip or detachment surfaces formed by discontinuities within the rockmass; which are more realistic especially in blocky/ very blocky relative competent rock masses (σci≥2.5MPa) and hard rocks.
The main aim of this course is to familiarize the geotechnical engineer/ engineering geologist with the principles of FDM numerical modelling and how to utilize the capabilities of UDEC, in slope stability problems in rock.
The course will focus on step by step building models in UDEC, examining the impact of material and discontinuity parameters, construction sequence and efficiency of slope stabilization measures.
