水电工程施工危险源关联辨识方法及其应用

Identification Method of Hydropower Project Construction Hazards Source and Its Application

定量分析水电工程施工危险因素导致事故的重要程度,对各个因素需关注的优先顺序做出判断,对危险源大的单个因素做出提前预警。综合作业条件危险性评价方法(LEC)和层次分析(AHP)评价方法,结合工程实例,确定出施工中的风险指数以及危险等级,对施工危险源的单个影响因素进行关联分析,得出单个因素的权重值和危险性排序。最终根据危险性排序表优先处理等级高的危险源,为水电工程施工危险源评价和管理提供依据。

Quantitative analysis of construction risk factors which lead to accidents,and prioritize these factors so that early warning can be made regards to the most dangerous factor.Integrated risk assessment methods（LEC）and analytic hierarchy process（AHP） evaluation methods were adopted in this research to an engineering example,the risk level of all the risk factors was determined,individual effects of one single risk factors was evaluated and their sequence was acquirred.Eventually according to the sequence of high priority risk hazards,this research can provide basis for hazard assessment and management of hydropower project construction.
