Optimization Study of Building Foundation Pit Support Scheme under Eccentric Pressure
This paper deeply discusses the optimization problem of building foundation pit support scheme under eccentric pressure.Through the detailed analysis of the generation and change of eccentric pressure,the influence mechanism of eccentric pressure on the force and deformation of foundation pit is clarified.Based on the general situation of the project,the initial support scheme and monitoring scheme are proposed.In order to verify and optimize the design scheme,a three-dimensional model of foundation pit support was established by using numerical simulation technology,and the key parameters such as sur-face settlement,underground continuous pile deformation and horizontal displacement of envelope pile were analyzed.Based on the simulation results,a targeted optimization scheme is proposed to improve the safety and stability of the foundation pit supporting structure.The research results of this paper not only provide theoretical support for similar projects,but also provide a new idea for the design and optimization of foun-dation pit support scheme.
