Research on the Influence of Deep Foundation Pit Excavation on Adjacent Shallow Foundation Buildings and Protection Schemes
Based on the on-site monitoring data of foundation pit engineering and numerical simulation method,this paper analyzes the influence of deep foundation pit excavation on surrounding shallow foundation buildings based on the Dayuan station on Guangfo Ring Line.The correctness of the established numerical model is verified by the on-site monitoring data of the foundation pit engineering,and the stiffness of the foundation pit support structure is improved.The methods of soil reinforcement outside the foundation pit and groundwater level control effectively control the surface differential settlement and the deformation of shallow foundation buildings.
