Summary
The subject consists of modeling complex problems in the underground and
geotechnical engineering. Students are introduced to the requirements to the input data, 2D and 3D finite element method and other numerical methods, which are used for the modeling of geotechnical problems. To these methods belong boundary element method, finite difference elements method and distinct element method, which is suitable for the modelling of discontinuous rock mass The students engaged in tasks of modeling of slope stability with consideration of various types of stabilizing elements (bolts, nails,geotextiles, etc.), modeling the effects of groundwater in the slope, stability of rock walls. Another area is the role of the underground construction - stability of tunnels and underground collectors, taking into account support construction of various types (including spatial models), calculations sheeting and foundation structures. The course also deals with the fundamentals of back analysis and stochastic methods.
