桥头跳车综合防治技术研究

Reason analysis on preventive techniques of vehicle bump at the end of bridge

在分析桥头不均匀沉降产生原因的基础上,从地基、路堤、路面等方面提出综合桥头跳车防治技术,并针对常规桥头搭板设计方法中存在的弊端,提出了改进的搭板设计方法,同时对排水系统也作了分析和改进。

Based on reason analysis of the differential settlement at the end of bridge, the preventive techniques of vehicle bump at the end of bridge were studied from the aspects of how to reduce foundation settlement and embankment settlement and how to avoid differential settlement and so on. The disadvantage of the conventional design method of bridge approach slabs and drainage system was analyzed, and the paper put forward the ameliorated design method.
