［摘要］该工程位于河南省郑州市中牟县，总建筑面积约11万m2。因原场地开发已按照原建筑的结构设计完成了预应力管桩的施工，新建建筑根据施工现场、场地地质情况和设计要求等，选择采用长桩与短桩相结合的方法对地基进行处理。通过本工程的设计和施工实践，验证了长短桩复合地基设计方案的合理性。

Abstract： The project is located in Zhongmou county, Zhengzhou city, Henan province. The total building area of the project is 110 thousand square meters. The construction of prestressed pipe pile has been completed according to structural design of original building because of the original site development. According to construction site, site geological conditions and design requirements, long and short piles were adopted to deal with the foundationg for new building. Through the design and construction practice of the project, the rationality of the design scheme of the composite foundation with long and short piles was verified.
