西岸泵站地基处理方案优选及应用

Optimization on Foundation Treatment Scheme of the Pumping Station in West Bank and Its Application

综合考虑佛山市南海区西岸泵站工程地质条件、上部结构特点、施工条件、环境保护和运行要求等因素,初选Ф400预应力砼管桩复合地基+钢板桩截渗及Ф500水泥搅拌桩复合地基+水泥搅拌桩截渗两种地基处理方案。通过技术经济分析和对比,最终确定Ф500水泥搅拌桩复合地基+水泥搅拌桩截渗处理方案为本工程的地基处理方案。

This paper comprehensively considers the engineering geological conditions,the upper structure characteristics,construction conditions,environmental protection and operation requirements and other factors of the pumping station of the west bank located in Nanhai District,Foshan City.Two kinds of ground treatment schemes of Ф400 prestressed concrete pipe pile composite foundation ＋ steel sheet pile seepage and Ф500 cement mixing composite foundation ＋ cement mixing pile seepage are selected.Through the technical and economic analysis and comparison,the treatment scheme of Ф500 cement mixing composite foundation ＋ cement mixing pile seepage is eventually determined to be the ground treatment scheme of this project.
