斜腿刚架拱桥加固后静载试验及评价研究

The static load test and evaluating analysis of reinforced slant-legged rigid frame bridge

通过对两座采用外包混凝土法加固的斜腿刚架拱桥进行静载试验,得到加固后桥梁在等效车辆荷载作用下的实际应力水平和变形,并将试验结果与应用有限元软件ANSYS算得的理论结果进行比较,进而对外包混凝土加固法的实际应用效果进行评价。

By static load test for two slant-legged rigid frame bridges of using enwrapping concrete method, gain the reinforced bridge＇ s real stress and deformation when it effect equivalent load, and get comparison on the experiment results and theory results calculated based in finite element soft ware ANSYS, thus evaluating practical application effect of surrounding concrete reinforcement method.
