基于AHP-变权综合评价法的斜拉桥健康状态评估

Cable-stayed bridge health condition assessment based on AHP-comprehensive variable weight evaluation method

提出了基于AHP-变权综合评价法的桥梁健康状态评估方法,根据斜拉桥的结构特点建立其层次型评估体系,从而将复杂的桥梁结构健康评估指标层次化。最后结合工程实例,对某斜拉桥健康状态进行综合评估,验证了该方法的可行性,对于桥梁结构的安全及维护具有重要的意义。

This paper puts forward bridge health condition assessment method based on AHP-comprehensive variable weight theory, establishes analytical hierarchy process according the structural features of cable-stayed bridge, and hierarchicalizing complicated bridge health condition as- sessment index. In the end, combining with the engineering case, it comprehensively evaluates the health condition of the cable-stayed bridge, testifies the feasibility of the method, which has important meaning for bridge structure security and maintenance.
