基于荷载试验的空腹式双曲拱桥工作性能分析

Analysis of working capability for open-spandrel double-curved arch bridge based on load test

以某空腹式双曲拱桥为背景,采用MIDAS有限元软件建立理论模型,再进行静动载试验,将实测值与理论计算值及相应规范进行比较分析,评价桥梁结构在荷载作用下的实际工作性能。结果表明,该桥能满足设计荷载等级要求,并为同类桥梁的工作性能分析提供参考。

In this paper, the theoretical model of the open-spandrel double-curved arch bridge was constructeda nd analyzed by using MIDAS soft ware . Then static load test, dynamic load test were completed, and the testdata were compared to theoretical value to evaluate the working capability of the bridge. It is indicated that thebridge meet the design requirements, and the testing m ethod suggested in this paper can provide reference dataof evaluateion of working capability for the same style bridges.
