Excavation Engineering Construction Countermeasures Study In Tianjin Sunshine Garden Project

Our country is a rapidly developing countries of urbanization, high-rise building emerge in endlessly, deep foundation pit excavation and supporting in high-rise buildings, while being used frequently in the pit excavation and supporting construction also belong to the most complex is civil engineering, one of the areas of technology.In this paper the latest theory on excavation engineering, led by reference about the success of excavation engineering, past the wafer, combined with Tianjin sunshine garden project, with Canon foundation pit engineering project this as the research object, by integration of theoretical and practical way, explore the area feasible for supporting schemes, and summarizes the design of foundation pit engineering about area with construction experience, for follow-up about excavation engineering research provides a valuable reference purposes.Sunshine garden project is located in Tianjin Nankai district old residences region, fire edom, enterprise, west of south street, south road residences road north, this project has a total construction area of about 209615.6 m2 (including underground garage 52212.77㎡), building structure form of reinforced concrete frame shear wall structure, the project DaGu elevation ++ 0.000 equivalent to natural m, three elevation -0.9m floor. Underground outdoor palisade structure are 0.8m thick underground continuous wall of foundation excavation, and do a retaining wall, internal three-course reinforced concrete support system.
