Learning outcomes

Objective – advanced knowledge in the field of mathematical modeling of underground structures, focusing on material models for rock environment and structural elements (lining, bolts, anchors, etc.) and technology in underground engineering.

Output - theoretical basics of material models, including the determination of their input parameters used in the modeling of underground structures, together with the possibilities of modeling of selected technological processes in the execution of underground work (marginal conditions, building phase, etc.).

Prerequisites

Basic principles of geology, engineering geology, soil mechanics, building materials, structural mechanics, elasticity and plasticity theory, foundation engineering, geodesy, building materials, basic principles of railway, overground and water structures.

Planned educational activities and teaching methods

The lectures are supplemented by numerical simulation of laboratory tests for different material models and their comparison with real results.

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Forms and criteria of assessment

The course is finished by an oral exam.
