软土地区桩基后注浆现场试验研究

Research on site test for post-grouting pile basing in soft-soil areas

在结合地质条件进行分析的基础上,论证了深厚软土地区进行桩基后注浆实验的可行性,制定了注浆实验的试验工艺流程,通过现场试验与实验成果分析,建立了一套适合软土地区钻孔灌注桩后注浆的施工方法与工艺,对同类工程具有一定的参考价值。

Based on the analysis of the geological conditions,the study indicates the feasibility for the post-grouting pile basing experiment at deep and thick soft-soil area,makes out the craft procedure for the grouting experiment,and establishes a set of construction methods and craft for the post-grouting for bored grouting pile,so as to provide certain reference value for similar projects.
