摘　　要：根据钢筋混凝土梁式桥结构特点 ,首先给出构成各部分基本受力构件的承载能力降低率 ,再依据层次分析法原理 ,将其合成为结构体系的评估指标 ,从而建立起桥梁结构体系的实用评估方法 。According to the characters of reinforced concrete girder bridges, this paper gives the decreasing rates of bearing capacity of basic members in each segment, and integrates the decreasing rates into evaluation index of the structural system based on the theory of analysis, then it creates a useful evaluation method for bridge structural system, and on this basis an automatic evaluation system can be developed.
