桥头跳车现象的形成机理和处置办法探讨

Discussions on Formation Mechanism and Treatment Methods of Bridge-head Bumping Phenomenon

道路桥梁桥头跳车现象对道路行车的舒适性和安全性造成了较大的影响,成为道路工程和相关学术界关注和研讨的问题。文章阐述了桥头跳车现象的成因和主要危害,从设计和施工因素、台背填料的压缩特性、路基和桥台整体结构特性方面,分析了桥台和主路之间的沉降原因,并探讨解决桥头跳车问题的主要途径。

The bridge-head bumping phenomenon of road bridges caused a greater impact on the driving comfort and safety,and it has become the common concern and research issues in road engineer-ing and related academia fields.This article described the causes and major hazards of bridge-head bumping phenomenon,and from the design and construction factors,compression characteristics of abutment packing materials,and overall structural characteristics of roadbed and abutment,it analyzed the reasons for the settlement between abutments and main road,and discussed the main way to solve the bridge-head bumping problem.
