针对我国目前桥梁技术状态评定方法的不足,以层次分析法为基本评定模型,引入G1法和熵值法进行主观和客观赋权,并采用两种赋权法集成的线性加权组合法确定最终权重.最后给出了桥梁状态指数评定与桥梁重要构件缺损状况评定的并行综合评定方法.通过工程实例比较,并行综合评定方法具有计算原理简明、计算工作量少、结果可靠的优点.%This paper aims at shortcomings of bridge assessment method.The AHP（analytic hierarchy process） is used as the basic evaluation model,G1 method and entropy method are introduced for subjective and objective weight,and the weighting method determines the final weight by integrating the weighted linear combination method.And the bridge condition index evaluation and bridge important component defect situation evaluation of parallel comprehensive evaluation method are put forward.Through the project example,this method has simple calculation principle,less workload,reliable results.
