浅谈公路桥头跳车的成因及处理措施

Brief Talk about the Causes and Treatment Measures of Bump at Bridge-Head

从设计、施工和回填采料等不同角度并结合工程实践综合分析桥头跳车的形成原因,针对不同地基和不同成因的桥头跳车提出处理措施,虽然所采取的措施并不能完全消除桥头跳车现象,但实践证明能有助于提高台背回填工程质量和行车舒适性。

From the different angles of design, construction and material backfill and combined with the engineering practice, the paper comprehensively analyzes the causes of bump at bridge-head and puts forward the treatment measure for the bump above different grounds and of different causes. Although the measures adopted cannot completely eliminate the bump phenomenon at bridge-head ,they are proved to be helpful to improve the engineering quality of the backfilling behind the abutment and the amenity of driving.
