红粘土地区深层搅拌桩的应用分析

The Application of Deep Mixing Method in Red Clay Soils

随着社会经济的发展,建筑物越来越高,红粘土作为一种在我国南方广泛分布的特殊土,其本身的承载力已经不能满足建筑物的需求。通过工程实例,介绍了红粘土地基采用水泥土搅拌法进行地基处理的设计方法以及水泥搅拌桩施工工艺,并提出水泥搅拌桩施工过程中的质量控制措施,可供类似工程实践及设计参考。

Red clay is a widely distributed soil in Southern China. With the economic development in recent years, the demand for the bearing capacities for buildings with increasing height exceeds the capacity limit of the natural red clays. This paper presents a method that improving the bearing capacity of the red clay soil by using cement mixing. The design and construction aspects of the soil mixing in red clay are also introduced. The quality control measures during the construction are also pro- posed.
