压浆碎石桩技术研究

Research on Technology of Grouting Gravel Pile

介绍了压浆碎石桩的技术特点、作用机理,并对其用于高填方软基处理和桥梁基础加固进行了研究。结果证明,压浆碎石桩处理技术具有排水固结、胶结、竖向增强、置换等综合作用,为高速公路软基、不良地基及桥梁基础加固和桥头跳车处理等提供了一条新的途径。

The technical characteristics and mechanism of grouting gravel pile were introduced, the application of grouting gravel pile in dealing with the high embankment soft base and bridge foundation reinforcement was studied. The results show that grouting gravel pile treatment technology has the functions of drainage solidifica- tion, cementing, vertical strengthen and change, which applies a new way to deal with soft foundation and poor foundation in expressway, especially with bridge foundation reinforcement and bumping at bridge-head.
