水泥砂浆搅拌桩加固机理及应用

摘要

The thesis introduces reinforcement mechanism of cement-mortar mechanism. In light of cement-mortar mixing pile reinforcement mechanism used in Xiang-Pu railway soft foundation,it carries out N10 examination,core-pulling examination and static load test comparison. Cement-mortar mixing pile composite foundation bearing capacity and single-pile capacity meet the design demands and improves the soft founda-tion bearing capacity.%介绍了水泥砂浆搅拌桩的加固机理，在此基础上，针对向莆铁路软基采用水泥砂浆搅拌桩加固处理的工程，进行了 N 10检测、抽芯检验和静载试验比较，通过比较可知，水泥砂浆搅拌桩复合地基承载力和单桩承载力都能够符合设计要求，使软土地基承载力得到了明显提高。
