摘　　要：危险源的辨识与评价是水利水电工程中安全管理工作的核心,然而目前大多数水利工程施工企业仍采用传统的作业条件危险性评价法(LEC)进行危险源评价。由于LEC法对评价人员的经验有较强的依赖性,导致采用该方法不能准确评价危险源。针对LEC法的不足,通过引入控制因子替换严重程度指数,并综合客观施工环境与施工人员安全意识对危险发生概率进行设定,提出了改进LEC法,然后引入故障树分析法(FTA)对危险程度参数进行优化,得到改进LEC-FTA法。以珠江三角洲水资源配置工程某标段的机电安装工程为例,应用改进LEC-FTA法对机电安装事故中各危险源进行评价计算,结果表明,改进LEC-FTA法评价结果可兼顾危险源的危险程度与其在事故发生工程中的重要程度,与实际情况相符。The identification and evaluation of hazards is the core of safety management in water conservancy and hydropower projects,but most water conservancy engineering construction enterprises still use the traditional LEC method for hazard source assessment.Due to the strong dependence of the LEC method on the experience of the evaluators,the use of this method cannot accurately evaluate the hazards.In view of the shortcomings of the LEC method,by introducing the control factor to replace the severity index,and setting the probability of danger based on the objective construction environment and the safety awareness of construction personnel,an improved LEC method was proposed,and then the FTA method was introduced to optimize the risk degree parameter,and the improved LEC-FTA method was obtained.Taking the mechanical and electrical installation project of a certain section of the Pearl River Delta Water Resources Allocation Project as an example,the improved LEC-FTA method was used to evaluate and calculate the hazards in the mechanical and electrical installation accidents,and the results showed that the evaluation results of the improved LEC-FTA method could take into account the danger degree of the hazard source and its importance in the accident project,which was consistent with the actual situation.
