Subject aims expressed by acquired skills and competences

The aim is to teach students to synthesize knowledge from different areas of the wider focus (rock and soil mechanics, the theory of elasticity and strength, marking underground structures, structural analysis, concrete and steel structures), design and safe cost-effective underground design, analyze and interpret correctly real behavior of underground structures and compare the results obtained in-situ with the theoretical calculations based on various calculation methods and with the results obtained by mathematical modeling. One of the most important skills is also carried out predicting the behavior of some underground structures in the geological environment and local conditions.

Summary

The course deals in detail with the problems of structural assessment and design of underground structures that ensure stability, uptime and security of underground workings. On the basis of evaluation the stress-strain state around the underground working the basic calculation procedure for determining load reinforcement (lining) is defined, additionally deals with classification of computational methods and their usability and devotes considerable attention to static underground structures all types, incl. anchoring rock and rock mass improvement. Knowledge and skills obtained by students completing the course: By completing the course students acquire a detailed knowledge of the stability of underground works, their statics and reinforcement methods of design and assessment of structures. They learn to solve basic problems of stability underground works and assessment of structures by a systematic approach to the evaluation of computational methods and the quality of rock mass. Student will be able to use some software and evaluate the reliability of the results.
