Foundation Design Of Large Commercial Complex

To test the bearing capacity of CFG pile composite foundation with CFG pile layout,combined with Zhengzhou,a high-rise building,as the construction scheme adjustment,construction layer consists of 26 layers to 34 layers and the increase of CFG pile composite foundation project construction has been completed,the original composite foundation scheme meets the requirements of the plan of the new building has become a major problem.Through checking the bearing capacity of CFG pile and the bearing capacity of composite foundation,and comparing with the test results of CFG pile single pile bearing capacity and composite foundation bearing capacity,the bearing capacity of CFG single pile and the bearing capacity of composite foundation are determined.Meanwhile,the three-dimensional finite element software PLAXIS3D is used to establish the three-dimensional model of composite foundation to calculate the settlement and deformation.Through the analysis of the calculation results,we can comprehensively predict the feasibility of the original composite foundation scheme to withstand the load of 34 storey buildings and meet the requirements of settlement and deformation at the same time.The layout of anti floating anchor should be considered in combination with the basic form of the building and the level of the water level.When the raft foundation is used,it should be arranged in the middle of the raft or the small vertical load.In addition,as the anti floating bolt belongs to the concealed project,the corrosion of the ground water and soil should be fully considered in the design process,and a certain safety reserve should be reserved so as to avoid the occurrence of chain damage.
