摘要
通过对下泾头空心板简支梁桥在不同加宽方式下结构受力性能影响的计算分析,可以得到两点结论:一是通过有限元分析可以看出,经过加宽后,旧桥的受力性能会得到一定的改善,结构整体承载力得到提高;二是对于空心板桥,横向联系刚度能影响结构的受力性能。
Two conclusions can be got through Calculation and analysis on influence of structure force of Xiajingtou hollow board bridge in different widening style. The first conclusion is that the force performance of old bridge will be improved and the structure carrying capacity also can be improved after widening by finite analysis. The second conclusion is that the transverse joint stiffness will affect the force performance of structures.
