改双曲拱截面为箱形截面技术的应用研究

Research on application of change from hyperbolic arch section into box section

以某双曲拱桥为例,介绍了大桥原有病害情况及加固方案,通过应用改双曲拱主拱圈截面为箱形截面的加固技术对双曲拱桥进行加固,从而达到提高大桥承载力,改善整体受力性能的目的。

Taking some hyperbolic arch bridge as an example,the paper introduces the diseases on the bridge and its intensification scheme,intensifies the hyperbolic arch bridge by applying the strengthening technique from hyperbolic arch section into box section,so as to improve the loading capability of the bridge and to enhance the stressed performance of the whole bridge.
