摘　　要：工程实践中常常采用静载试验的方法评定既有结构的承载能力及工作状态。本文应用ANSYS软件中的梁单元建立了基于实测资料的双曲拱桥的受力模型 ,并对加载进行分析 ,证明了用ANSYS计算分析比较可行 。In the engineering practice the method of static load test is usually used to evaluate the capacity and working status of the existing structure. The paper applies the beam unit in ANSYS software to establish the forced model of double curved arch bridge based on the actual measurement data. It also analyzes the loading to prove that the calculation and analysis by ANSYS is more feasible. At the same time, it disproves the reliability of static loading test result.
