Rock Mechanics in Underground Construction. ISRM International Symposlym 2006 4th Asian Rock Mechanics Symposium / Механика горных пород в подземном строительстве

In the context of underground construction, forensic engineering is taken to be the application of engineering principles and methodologies to determine the cause of a performance deficiency, often a collapse, in an excavation, and the reporting of the findings, usually in the form of an expert opinion within the legal system. The procedures that may be used in forensic geotechnical investigations and the interface of the engineer with the legal system are discussed. The application of the principles and methodologies outlined are illustrated through a brief account of the investigation of the collapse of a small part of an excavation in the Lane Cove Tunnel Project, Sydney, Australia, on 2 November, 2005. <...>
