曲线桥梁偏位影响分析及维修加固方案

Curve deviation of bridge impact analysis and maintenance reinforcing scheme

位于平曲线上的桥梁,当平曲线半径较小时,其受力和变形特点与直线桥梁有较大差别。对影响曲线桥梁梁体偏位的多种因素进行了定量分析,并提出了相关建议。

When a bridge is on plain curve , especially the plane curve radius was relatively small, the stress and deformation characteristics are great different from the lin- ear bridge. In this paper, a quantitative analysis is ap- plied to find out the misregistration factors of the beam, which is on the plane curve, and put forward some sug- gestions.
