摘要
对地铁施工风险事故产生的原因进行分析,首先绘制故障树分析(FTA),在此基础之上建立二元决策图(BDD)结构,对地铁施工安全风险进行定性和定量双重分析。通过遍历BDD结构,计算得出风险事故率和基本事件重要度两项评价指标。为了简化逻辑运算,通过计算机编程代码来实现,有效避免了故障树分析中的组和爆炸问题。依据所得数据,项目部安全管理人员可以确定引发事故的关键因素,制定针对性较强的控制措施,较大程度上避免后续类似风险事故的发生。
The causes of subway construction risk accidents are analyzed.Firstly,the fault tree analysis(FTA)is drawn.On this basis,the binary decision diagram(BDD)structure is established to analyze the subway construction safety risks qualitatively and quantitatively.By traversing the BDD structure,two evaluation indexes,risk accident rate and basic event importance,are calculated.In order to simplify the logic operation,it is realized by computer programming code,which effectively avoids the group and explosion problems in fault tree analysis.According to the obtained data,the safety management personnel of the project department can determine the key factors causing the accident,and then formulate targeted control measures to avoid the occurrence of similar risk accidents to a great extent.
