加固软土地基的水泥系深层搅拌法开发

我们从1987年起、针对武汉地区深厚软粘土层的特点,开发了用以加固软土地基的水泥系深层搅拌法,开展了各种类型的室内和现场的试验研究。 1987年9、10月份,在武汉首次运用这种方法,对一幢8层住宅楼的软土地基进行加固,加固土的强度完全满足设计要求,复合地基的容许承载力达到10t/m~2。

Application of Deep Mixing Method with Cement Hardening Agent to Reinforcement of Ground

Considering the specific conditions of deep soft ground in Wuhan, the deep cement mixing method was developed from 1987， in order to reinforce the soft ground. Since then, variety of testing studies both in lab, and in field have been made. From September to October in 1987, this method was first used to reinforce soft ground satisfied completely design requirement with allowable bearing capacity of 16 t/m2 .
