地基基础是建筑物结构的重要组成部分。施工中经常会遇到天然地基的承载力低或变形难以满足工程要求 ,需进行地基处理的情况。目前 ,地基处理方法很多 ,其中 ,用水泥土桩进行加固形成复合地基是一种比较新的施工技术 ,对于淤泥质土及含水率高的粘性土、粉土非常适宜。本刊 2 0 The foundation of the foundation is an important part of the building structure. In the construction, it is often encountered that the bearing capacity of the natural foundation is low or the deformation is difficult to meet the engineering requirements, and the ground treatment is required. At present, there are many methods for foundation treatment. Among them, the use of cement-soil piles for reinforcement to form a composite foundation is a relatively new construction technique. It is very suitable for muddy soil and cohesive soil and silt with high moisture content. Publication 2 0
