Support Design and Deformation Influence Analysis of Deep Foundation Pit of Adjacent Buildings
In order to ensure the construction safety of deep foundation pit of adjacent buildings,this paper relies on the actual project to carry out the deformation analysis of deep foundation pit supporting structure to adjacent buildings based on numerical simulation.The results show that the horizontal displacement of the top of the foundation pit increases with the increase of the excavation depth,and the vertical displace-ment of the top of the foundation pit increases slowly at first and then rapidly.The simulated value of the building caused by foundation pit ex-cavation is less than the measured value,and the settlement value of all the buildings is less than the deformation control index value,which confirms the safety and stability of the foundation pit support design scheme.
