摘　　要：结合 2个工程实例———石灰搅拌桩和CFG桩复合地基 ,进行了室内试验、现场载荷试验及非线性有限元分析 ,探讨这两类复合地基受力、变形性能的不同所在 。Indoor experiment, field load test and non\|linear finite element analysis were conducted of two kinds of composite foundation\|lime mixed pile and CFG pile. Exploration was made of difference of the two piles on force and deformation performance, verifying the reliability of data analysis method and rationality of foundation soil model selection.
