基于FTA-BN的塔吊安全事故致因分析
Causation analysis of tower crane safety accidents based on FTA-BN
摘要
Abstract
Addressing the frequent occurrence of tower crane accidents,this study investigates critical causation factors through accident data analysis and proposes a systematic risk assessment method integra-ting Fault Tree Analysis and Bayesian Network(FTA-BN).The research identifies accident causation from four dimensions:human factors,equipment conditions,management practices,and environmental elements.Utilizing Grounded Theory,we conduct qualitative analysis on tower crane accident cases to extract 29 causation factors and construct a fault tree model,subsequently mapped into a Bayesian Net-work.Quantitative evaluation through reverse reasoning and sensitivity analysis reveals nine critical cau-sation factors with significant risk impacts:incomplete safety management systems,non-compliance with specialized construction plans,structural/component failures of tower cranes,violation operation inadequate governmental/supervisory oversight,insufficient safety awareness,concurrent operations,im-proper equipment maintenance,wire rope fractures,and hook disengagements.The results demonstrate that management factors constitute the core of systemic risks.关键词
