摘　　要：为了科学、客观地确定桥梁施工安全风险因素的权重,把握好影响桥梁施工的主要因素,有效控制桥梁施工风险,提出将两个因素的频数比作为各因素之间相对重要度构造判断矩阵,求得指标权重。通过对武汉二七长江大桥施工期安全检查表的数据频数进行统计分析,以风险因素频数比构造判断矩阵,应用Matlab进行计算,验证判断矩阵的一致性,确定各指标的权重排序,得出承台、安全网及防护围栏、大型设备交叉作业、吊机和混凝土工程为影响桥梁施工安全的主要因素,为今后桥梁施工安全管理提供参考。In order to scientifically and objectively calculate the weights of safety risk factors,grasp the main factors and effectively control safety risk during bridge construction,using the frequency ratio of two factors as the relative important degree in judgment matrix of AHP is proposed to calculate the index weight.The frequency data of safety checklist during Wuhan Erqi Yangtze River Bridge construction is statistically analyzed,the frequency ratios of two factors are used as the relative important degree in judgment matrix of AHP,through using mathematic calculation capabilities of Matlab to verify the consistency of judgment matrix,a conclusion is obtained,which shows the bearing platform,safety nets and protective fence,cross-operation of large equipment,crane and concrete works are the main causes,and provides a reference for safety management of bridge construction.
