摘要
文章研究的核心是使用FTA进行危险源辨识时对基层事件发生概率的统计。通过对一年时间内某房屋建筑施工单位下属41个标段的基础数据统计,运用对工序百分率法、故障时长百分率法对事故发生概率计算结果的影响对比,研究适用于房建工程焊接作业触电事故各危险源相对精确的统计方法,为建筑施工单位对焊接触电事故风险预先性分析提出改进思路建议。
The core of this paper is the statistics of the occurrence probability of root-events when using FTA for hazard identification. Based on one year time of 41 bid sections’ data statistics which subordinate to a construction company, using the methods of working-procedure-percentage and failure-frequency-percentage on the result of accident’s probability calculation to make a comparison, this research is suitable for electric shock accidents in construction welding to get a relatively accurate statistical method in hazard identification, and to provide some further advice to improve the risk analysis about the electric shock in construction welding.
