高压旋喷桩复合地基在回填区的应用

Application of high pressure rotary grouting pile composite foundation in backfill ground

提出了在多障碍物回填区采用高压旋喷桩代替CFG桩或与CFG桩协同作用的地基处理方法,并介绍了此方案的施工参数和控制要点,从而达到指导同类工程的目的。

A ground treatment method is presented that using the high pressure rotary grouting pile instead of CFG pile or cooperating with（CFG） pile in many obstacle backfill ground,meanwhile,the technique parameters and controlling points of this method in construction are also introduced,therefore reached the goal of guiding similar engineering.
