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

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.
