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。 Since 1987, we have developed a cement-based deep-stirring method for reinforcing soft soils in response to the characteristics of deep soft clay in Wuhan, and conducted various types of indoor and field experiments. In September and October of 1987, this method was first used in Wuhan to reinforce the soft soil foundation of an 8-story residential building. The strength of the reinforced soil fully met the design requirements, and the allowable bearing capacity of the composite foundation reached 10t/m~2. .
