Design of Underground Parking Lot Foundation Lower than Connecting Multi-storied High-rise Building Foundation/Yuan Bin(Beijing Huanyang Century International Architecture and Engineering Co., Ltd., Beijing 100037, China)

Abstract:The detailed load bearing analysis of a common foundation form in which the underground parking lot foundation is lower than the connecting multi-storied high-rise building foundation is provided. It offers the structural measures and calculating methods that should be applied to ensure the foundation"s stability, when dealing with this kind of foundation form. So the cross wall must be arranged at one side of the retaining wall as its lateral support. The calculating method of the cross wall is presented and an example is given. It comes with several examples which can be used as design reference.

Keywords:design of multi leveled foundation; stability of foundation retaining wall; structural measures
