摘　　要：本文通过CFG桩复合地基和水泥土桩复合地基现场载荷试验的工程实例 ,比较分析了铺设垫层与不铺设垫层两种情况下载荷试验所得出的沉降曲线 ,阐述了铺设褥垫层在载荷试验中的重要作用 ,提出在载荷试验中铺设垫层的必要性 ,使复合地基载荷试验结果更加准确实用。Through the field loading tests of composite foundation with CFG piles and cement-soil piles the settlement curves from loading tests are analyzed under the conditions of cushion or no cushion.The importance of the cushion in loading tests is discussed,and the necessity is also stressed.The use of cushion can make the results of loading tests more accurate and practical.
