Application of Schist Replacement Method in Soft Soil Shallow Foundation Engineering
In highway engineering,the method of ripping and silting is often used to reinforce the soft foundation with high water content,large pore ratio,weak water permeability and low shear strength.Based on the method of ripping and silting,the technology of stone replacement and filling in shallow foundation pit engineering of soft soil is proposed.The finite element analysis software PLAXIS 3D was used to simulate the process of foundation pit excavation and foundation reinforcement,and the influence of different thickness of flake filling on the bearing capacity and deformation of foundation pit was analyzed.The calculation results were compared with the measured data to verify the finite element calculation results.
