桥头跳车成因及防治

在深入分析桥头不均匀沉降产生原因的基础上,从地基、路堤、路面等方面提出桥头跳车综合防治技术,和针对常规桥头搭板设计方法中存在的弊端提出改进的设计方法,同时对排水系统进行分析和改进,这项研究可供工程实践参考.

Reason Analysis and Preventive Techniques of Vehicle Bumping at Bridge-head

Based on reason analysis of the differential settlement at bridge-head, the preventive techniques of vehicle bumping at bridge-head are 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 is analyzed, and it puts forward the ameliorated design method, which is beneficial to the analysis and improvement of drainage system. These provide reference for engineering practice.
