摘　　要：介绍了表征结构健康度的梁桥健康指数BCI,建立了梁桥健康评估层次分析模型,提出了以健康监测系统采集到的原始数据为基础,采用层次分析法对结构健康度逐级评定为思路,适用于梁桥健康状态评估的方法。最后,根据实桥采集的健康监测数据,采用论文提到的方法对原桥健康状态进行了评估,论证了该方法可运用于工程实际。The health index BCI of beam bridge,which represents the structural health degree,is introduced,and a hierarchical analysis model for the health evaluation of beam bridges is established.A method for the health status evaluation of beam bridges is proposed based on the original data collected by the health monitoring system and the hierarchical analysis method is used to evaluate the structural health degree step by step.Finally,according to the health monitoring data collected by the real bridge,the health status of the original bridge is evaluated by the method mentioned in the paper,and it is proved that the method can be applied to the engineering practice.
