改扩建项目中拼宽桥梁的横坡处置

The cross slope treatment of stitching and widening bridge in reconstruction and expansion project

以某改扩建项目中某拼宽桥的横坡处治问题为案例,针对新旧桥横坡不同导致拼宽时存在高差的问题,分析并阐述了不同情况下选用的处治方案,达到了横坡调整一致的效果,并总结出几点关于施工方案的影响因素,为类似拼宽桥梁横坡处治方法提供一定的参考。

This paper takes the cross slope treatment of stitching and widening bridge in a reconstruction and expansion project as a case,against the height difference of stitching and widening bridge that caused by the different cross slopes between the old bridge and the new bridge,mainly analyzes and elaborates how to choose the treatment plan in different situations to achieve the effect of adjusting the cross slope to be consistent.The paper also summarizes several influencing factors about the construction program,and provides some reference experience for similar expansion projects.
