Underground Construction III

Abstract

In-depth study of selected types of structures and topics in underground construction, as well as practical exercises in conceptual approaches to complex problems.

Objective

Students are familiar with the engineering aspects of selected types of underground structures (subaqueous tunnels, urban tunnels, immersed tunnels, cut-and-cover tunnels, caverns and shafts). Students gain in-depth knowledge of selected topics in underground construction (site ventilation, geotechnical aspects of deep geological repositories, field measurements, risk analysis and critical remarks on classification systems of rock mechanics). Students work in small groups using an up-to-date case study to learn how to conceptually analyse complex problems.
