【摘要】 为了更准确地确定铁路混凝土梁桥各分层结构(评估要素)及各种震害破坏形式的权重,为铁路混凝土梁桥的地震灾害损失评估提供依据,在分析铁路混凝土梁桥的构造特点及其震害破坏形式的基础上,采用层次分析法中的不同标度构建判断矩阵,计算铁路混凝土梁桥部件的权重,并对计算结果分析比较.研究表明,20/2～28/2指数标度的一致性最好,即采用该标度计算铁路梁桥各分层结构(评估要素)及各种震害破坏形式的权重最合适.更多还原

【Abstract】 In order to accurately determine the weights of hierarchical structure and earthquake damage mode of railway concrete girder bridges and provide a basis for the earthquake disaster damage assessment of railway bridges,this paper was based on analysing the construction features of the railway concrete girder bridges and destructive characteristic of seismic damage and proposed a method,which was to layer various kinds railway concrete girder bridges.It adopted several scales in the analytic hierarchy process,where the judgment matrix was built,the weights of railway concrete girder bridges parts were calculated,compared and analysed.It is found that consistency of 20/2～28/2 index scale is best,namely this index scale is most suitable to calculate the weights of hierarchical structure and earthquake damage mode of railway concrete girder bridges.更多还原
