This paper develops a systematic approach with detailed step-by-step procedures for safety management of existing buildings adjacent to tunneling excavation. The potential safety risk of a specific nearby building is assessed within four different risk levels, with the spatial neighbor relation (hazard parameter) and the building health condition (vulnerability component) taken into account. Compared...
This paper presents a systematicapproach for Overall Process Safety Management (OPSM) in tunnel construction, including safety system design, analysis, control and effect assessment. Wuhan Yangtze Metro Tunnel in China is used for a case study. A slurry shield machine is required to pass through Wuhan Ventilation Shaft with a cover depth of 42m, a hydraulic pressure of 0.44MPa and a curve radius of...
