摘要
按照G107国道上某典型的现役两跨空腹式双曲拱桥的结构受力特征,采用空间实体单元模型,利用An-sys软件及其接口程序,对该桥进行全面分析,研究其结构特点发现结构病害部位和形式与有限元分析十分一致.在分析的基础上,尝试为该双曲拱桥结构静载试验提供试验测点的布点方案,提出新的加载方案,给出部分试验结果,有限元与试验结果吻合得很好,得到一些有益的结论.
Choosing a hollow double curvature arch bridge with two spans on the national highway G107, according to structure loading character, ANSYS program is employed to analyze the whole bridge in which 3-dimensional solid element are used. It is to attempt to offer rational schemes of measuring point for static load test of the bridge theoretically; and a new loading way is brougt forward for a busy section of a highway. Structural character of the bridge is studied; a portion of results from static load tests are given that agree with that from finite element method.
