江海碧桂园酒店深基坑工程支护设计

摘要

Combined with basement and the building near the Garden Hotel foundation pit engineering ,the authors take the asymmetric branch support near the existing underground chamber ,select the appropriate supporting scheme ,reduce the foundation pit support project quantity and project cost .According to the prominent position of the foundation pit ,the design adopts the way of setting up the local support ,and solves the problem of the mutual influence of the anchor cable construction at exposed corners .It is used as references for similar deep foundation pit design .%针对江海碧桂园酒店基坑工程临近已施工地下室和建筑物，采取了不对称支护方式。临近已有地下室部分，采取土方开挖至相邻地块地下室外墙或部分利用原有支护，减少基坑支护工程量，降低工程造价。针对基坑阳角突出部位，设计采取局部内支撑的设置方式，解决阳角处锚索施工相互影响问题。可供类似深基坑设计参考。
