基于事故树理论的建筑施工现场作业人员触电事故致因分析

The Cause Analysis Based on Faulty Tree of Electric Shock Accidents to Operating Ppersonnel at Construction Site

本文采用系统工程的方法,对建筑施工现场可能发生的触电事故进行了事故树分析,并绘制出人员触电事故分析图,直观地表现了可能导致顶事件发生的各基本事件及其逻辑关系。通过对事故树的定性分析,得出了其基本事件的结构重要度,指明了预防事故的途径。

This paper adopts the method of system engineering, using faulty tree to analyze the possible electric shock accidents at construction site, and drafting analytical graph, intuitively demonstrated all basic events that may lead to top events and their logical relationship. Through qualitative analysis of faulty tree, learning the structural importance of basic events, indicating the accident prevention approach.
