基于模糊贝叶斯网络的桥梁施工安全风险评估
Safety risk assessment of cable-stayed bridge construction based on fuzzy Bayesian network
摘要
Abstract
In view of the increasing complexity of cable-stayed bridge construction and the frequent occurrence of safety accidents,a safety risk assessment model for cable-stayed bridge construction was constructed by combining Bayesian network algorithm and fuzzy set theory in order to evaluate the safety risk of cable-stayed bridge construction more accurately.With the construction procedure of cable-stayed bridge as the main line,combined with literature research and accident analysis,the risk factor index system of cable-stayed bridge construction was established from two aspects:structure and personnel safety risk.Considering risk probability and loss comprehensively,the risk level was determined based on Bayesian network algorithm and fuzzy comprehensive evaluation method respectively,and the risk matrix based on ALARP principle was evaluated.The model was used to evaluate the construction safety risk of the case bridge,and the evaluation results and feasibility of the model were illustrated.关键词
