摘　　要：荷载试验是对大跨度桥梁承载能力和结构性能进行评价的有效手段。以广中江高速公路的一座双塔预应力混凝土斜拉桥为例,利用Midas/Civil建立该桥空间有限元模型进行计算分析,依据相关规范对该桥进行了荷载试验及相应分析,荷载试验数据结果显示该桥承载能力及动力特性满足设计要求。Bridge load test is an effective method to evaluate the bearing capacity and structural performance of bragspan bridges. Taking a twin tower prestressed concrete cable-stayed bridge in Guangzhongjiang Expressway as an exampie, the finite element analysis model has been established through Midas/Civil, load test amt corresponding analysis have been performed according to the related standards and rules of the bridge and the experimental data haw＇ shown that the bridge bearing capacity and dynamic characteristics of the main spans could meet the design requirements.
