The Design Of Foundation Pit Supporting And Its Application In Zhumadian District

With the quick development of buildings in city. The development in buildings and underground space become more and more. Lots of deep excavation is brought with it. As an aspect of geotechnical, the design, construction as well as monitoring etc. have become an important issues, which influence the quality of engineering in construction field. Not only the construction, but also the buildingsnearby, pipes, roads etc.,are affected by it. So, the research to excavation is significant in both theory and engineering practice.This article combines the reality of Zhumadian district, take the excavation of ZhidiTianzhong Garden as a relies, concerning conditions nearby, soil conditions, the depth and shape, as well as local experiences, optimize designs the program of foundation pit, and showes calculation of design of foundation pit, including internal force of retaining structure, reinforced concrete pile supporting, anchor design as well as stability, and achieves a good result.
