Abstract The project is designed to Zhenjiang Nanshan yipin 1 #, 2 #, 3 #, 4 # residential’s excavation . According to the survey report of the project and design requirements of the mission statement, considering the economic, safety, technical, construction and engineering area convenience geological conditions for the structural design of foundation pit. This project finalized support scheme using cement soil gravity retaining wall and drain piles supporting hybrid structures, the use-by-layer excavation, supporting force constant force calculation method. Design elements include: a comparison as well as support scheme selection, earth pressure and internal forces supporting structure calculations, the overall stability of the pit, precipitation design, construction design, electronic data checking and so on. Design basis for "Building Pile technical specifications" (JGJ94-2008), "Design of Concrete Structures" (GB50010-2010), "Technical Specification for Construction Excavation" （JGJ 120-2012） , "steel knot design specifications" GB50017-2003, "building Foundation design Code" (GB50007-2011).
