Safety Risk Analysis of Box-Culvert Jacking Construction by Using Fuzzy Fault Tree Method Based on WBS-RBS

Article Preview

Abstract:

The box-culvert jacking of highway constructions crossing the existing railway is construction difficult and technically complex. If there are safe accidents, it will bring great loss. According to this situation, a new method based on WBS-RBS is presented in this paper to comprehensively identify the risk factors of safety accident with the fault tree, and then the fuzzy probability of basic events are described to triangle fuzzy numbers. Furthermore the happening fuzzy probability of the top event can be calculated. The proposed method provides a scientific method for the safety risk analysis of similar engineering.
