摘　　要：以某化工厂为例,进行了碎石桩+CFG桩二元复合地基的设计,并从地基承载力、消除液化效果、综合效益方面分析了处理效果,工程实践证明,二元复合地基在消除地基土液化的同时还满足了结构对地基承载力差异化需求,是处理地基土液化的有效方法。Take a chemical plant for example,this paper presents the design of the binary-pile composite foundation of gravel pile and CFG pile. The treatment effect is analyzed from the foundation bearing capacity,the effect of removing soil liquefaction,the comprehensive benefits. The engineering practice shows that the composite foundation can eliminate the liquefaction of foundation soil,at the same time,it also meet the needs of foundation bearing capacity from different structures. Binary-pile composite foundation is the effective method to deal with the liquefied soil.
