Course content

Numerical modelling in geomechanics, in 2D and 3D.

Lectures: Lectures introduce the theory of numerical methods used in rock mechanics, with applications in tunnel engineering, geothermal engineering, mining engineering, and nuclear waste disposal. This includes finite-element method (FEM), boundary-element method (BEM), discrete-element method (DEM), finite-difference methods (FD), hybrid methods, coupled models. In addition to building a solid theoretical foundation for exercises, more practical topics such as types and use of boundary conditions, in-situ stresses, material modelling etc are covered.

Exercises: Practical use of RS2 for 2D elastic and plastic modelling, and EX3 for 3D elastic modelling. Model construction, input parameters, computation, result analysis, post-processing and reporting. Simulation of rock excavation, in situ rock stress and rock support. Other types of relevant programs may be also used in the course.

Learning outcome

Knowledge: Students will acquire basic knowledge about techniques of numerical modelling in rock engineering. The student will learn how to complete an independent project within the discipline.

Skills: Students will be capable of using state-of-the-art digital tools, like the RS2 and EX3 programs, for simulation of tunnel excavation, in situ rock stress, rock failure, jointed rock, and rock support. The student will be able to carry out a project within computational geomechanics, process and analyze the results, and write a project report in accordance with established standards and using relevant digital tools.

General expertise: Students will have solid understanding of theory of numerical methods that are used in the industry today. Students will understand capabilities and limitations of various digital tools that are currently used in the industry.
