Based on this,189 bridgesin the actual projects as a sample were selected,the connection between static test result anddanymic test result was built in this paper in order to assess the structure\'s bearing capacity bydynamic characteristics of bridge.The main contents are as followings:(1)On the base of actual observation records of bridge samples,the mechanicalproperties of the assembly slab bridge is obtained,and the mechanical characteristic ofhinged joint and bridge deck,the distribution of the guard rail in transverse direction are alsodiscussed.Based on the above analysis,the rational theoretical model is built,which offerssome reference to assess the structure\'s bearing capacity.

基于此，本文在实际工程项目中选取189座板桥作为样本，通过对样本桥梁实测静载挠度、应变和动载频率进行统计回归分析，建立桥梁结构动载试验结果与静载试验结果之间的关系，通过桥梁结构动力特性来评定结构承载力，论文主要完成了以下几个方面的工作：(1)以样本桥梁实测数据为基础反演装配式板桥受力特性，确定各种型式装配式板桥的铰缝受力特点、桥面铺装层受力特点以及护栏沿桥面横向分配原则，以此建立真实反映装配式板桥受力特点的理论计算模型，为装配式板桥承载力评定提供理论计算依据。
