Workshop at the TU Graz: Tunnelling in Fault Zones

摘要

Fault zones represent a major challenge in tunnelling for planners, geologists and contractors. It is not always easy to identify and localise fault zones quite apart from obtaining significant sample material in order to establish their characteristics. Normally the distinctive irregularity of fault zones makes it difficult to predict behaviour of the rock and in turn, planning of excavation and support as well as assessing the expected deformations.
