| 摘 要： | 在单一桩型复合地基设计计算方法的基础上，对组合桩型复合地基的承载力、沉降变形及软弱下卧层验算的计算方法进行了探讨，并结合工程实例加以验证。实例中将夯实干硬性混凝土桩与刚性素混凝土（CFG）桩组合运用于湿陷性黄土场地的地基处理，达到了消除湿陷和获得很高复合地基承载力的双重目的，且技术经济效益明显，应用效果良好。

| Abstract: | Based on the design calculation of Single pile composite foundation, the computational method of multi-type pile composite foundation＇s bearing capacity, compression deformation and soft underground stratum checking are discussed, and it is confirmed by the practical instances. At the same time, in order to eliminate the collapsibility of loess and increase the strength of foundation, the ram dry concrete pile and CFG pile are being used in the ground treatment of collapsible loess zone for the first time, remarkable economic results and application effects have been achieved. |
