摘　　要：为有效评价复杂干扰环境桥梁建设安全风险等级,建立基于Vague集理论的风险评价模型,通过辨识桥梁建设风险因素包括人员因素、材料设备因素、环境因素和组织管理因素,利用区间层次分析法求得4类风险因素权重,最后根据最大隶属度原则得出总体风险等级。In order to effectively evaluate the safety risk level of bridge construction in complex interference environment,a risk assessment model based on Vague set theory is established.First,identify the risk factors for bridge construction including personnel factors,material equipment factors,environmental factors and organizational management factors.Secondly,using the interval analytic hierarchy process to obtain the weight of four types of risk factors.Finally,the overall risk level is derived based on the principle of maximum membership.
