摘　　要：为了实现建筑施工现场危险源评价的定量化,在对事故后果的解构基础上,采用Delphi法和AHP法融合,构建事故后果权重体系,对传统LEC法进行改进。并以安徽省巢湖流域水生态修复与治理工程一十八联圩生态湿地蓄洪区施工3标工程为例,对工程施工中危险性较大的分部分项工程进行危险源危险性评估,确定危险性较大的分部分项工程土方开挖工程和起重吊装及安装拆卸工程危险源分值分别为520和110.16,研究结果可为针对性措施的制定提供科学依据。In order to quantify the assessment of hazard at the construction site,based on the deconstruction of the accident consequences,the Delphi method and AHP method are combined to build the weight system of the accident consequences,and the traditional LEC method is improved.Taking the construction of Lot 3 of the 18th Lianweiecological wetland flood storage area of the Chaohu lake basin water ecological restoration and treatment project in Anhuiprovince as an example,the hazard risk assessment was carried out for the divisional and subdivisional works with greater risks in the construction of the project,and the hazard scores of the earthwork excavation works and the lifting,hoisting,installation and disassembly works with greater risks were determined to be 520 and 110.16 respectively,providing a basis for the formulation of targeted measures.
