Taking some construction program in Xi’an as the example,the paper introduces the design for the composite foundation by combining with the engineering geological condition,analyzes the influence of the bearing course at pile end on resting phase of CFG pile’s composite foun-dation,and achieves some conclusion,so as to provide some reference for design of some similar pile foundations.%以西安市北郊某建设项目为例，结合场地的工程地质条件，对复合地基的设计情况进行了介绍，分析了桩端持力层对 CFG桩复合地基休止期的影响，得出了一些有意义的结论，为类似桩基设计提供参考。
