摘　　要：通过介绍一个由夯实水泥土桩和CFG桩构成的组合型复合地基的工程实例 ,说明在湿陷性黄土地区 ,采用组合型复合地基既可消除地基土层的湿陷性 ,又能获得较高的承载力 ,具有显著的经济效益。同时指出了根据单桩静载试验结果计算组合型复合地基承载力时应注意的问题。The case history of the combined composite foundation with compacted cement soil piles and CFG piles is introduced.In the region of collapsible loess,the application of combined composite foundation can not only eliminate the collapsibility of the soil but also improve its bearing capacity.It is prominently economical.Some problems should be paid attention to when the bearing capacity of the combined composite foundation is calculated from the loading test results of single pile.
