摘　　要：针对缺少设计资料的旧桥检测难题,以福州市永泰县大樟中桥为例,先实地检查测量获取桥梁结构形式、构件截面尺寸、材质强度、设计荷载等级等主要技术参数;再建立有限元模型计算控制荷载下的内力值、结构基频值和冲击系数;最后,通过荷载试验检测对桥梁结构承载能力作出评定。In response to the problem of detecting old bridges lacking design data,taking the Dazhang Middle Bridge in Yongtai County,Fuzhou City as an example,the main technical parameters of the bridge structure,component section dimensions,material strength,and design load level were obtained through on-site inspection and measurement;Establish a finite element model to calculate the internal force values,structural fundamental frequency values,and impact coefficients under controlled loads;Finally,the load-bearing capacity of the bridge structure is evaluated through load testing.
