结合工程实例浅谈桥头跳车处置方案

On treatment scheme for bumping at bridge-head with engineering examples

结合工程实例,通过分析桥头跳车原因,提出了其处置方案,对注浆加固机理及工程布置作了论述,重点就桥头跳车处置施工工艺作了探讨,并说明台背注浆对减轻桥头跳车现象有一定作用。

By combining with project examples,the paper according to the analysis of the reasons for the bumping at bridge-head,points out its treatment scheme,illustrates the grouting intensification principle and engineering layout,explores the construction craft of the bumping at bridge-head,and indicates the effect of the grouting at retailing backwall on avoiding the bumping at bridge-head.
