摘　　要：吉安大桥主桥为飞燕式钢管混凝土系杆拱桥,文章对该桥进行静载试验,介绍了试验工况及测点布置,同时基于结构有限元软件全桥仿真模拟分析,将试验实测数据与理论数据及规范值的进行对比分析,从而判断该桥在试验荷载作用下的实际工作状态是否满足设计要求。试验结果表明:该桥上部结构强度、刚度均满足设计及规范的要求,试验结果可供同类型桥梁试验参考。The main bridge of ji'an Bridge is a flying swallow type concrete-filled steel tube tied arch bridge.In this paper,the static load test of the bridge is carried out,and the test conditions and the arrangement of measuring points are introduced.At the same time,based on the full-bridge simulation analysis by the structural finite element software,the measured data of the test are compared with the theoretical data and the standard value,so as to judge whether the actual working state of the bridge under the test load meets the design requirements.The test results show that the strength and stiffness of the superstructure of the bridge meet the requirements of design and specification,and the test results can be used as reference for the test of similar bridges.
