Abstract:

Analysis and evaluation are made on the risks of hyperbaric operation in shield tunneling by comprehensive fuzzy evaluation method so as to effectively control the major hazards in tunnel construction and minimize accidents. The practice demonstrates that the method adopted can solve the problems in quantitative evaluations on the risks and has good operability.

Key words: shield tunneling, hyperbaric operation, risk factor analysis, FTA (fault tree analysis method), comprehensive fuzzy evaluation method
