Finite Element Simulation Analysis of Stability of Soft Soil Roadbed Slope
Taking the Soft Soil Foundation of the West Outer Ring Expressway Project in Tianjin Binhai New Area as the Research Object,this paper analyzes the stability characteristics and influencing factors of the soft soil road-bed slope,and uses the finite element software Plaxis to analyze the sensitivity effect of Mohr Coulomb material parameters on slope stability.By using the drainage line simulation sand well and sheet pile element simulation CFG pile methods of the software,several common foundation treatment methods during the loading process were simulated by gradually increasing the element to affect the stability and deformation of the foundation during the filling process.The conclusion can provide reference for the construction of soft soil subgrade.
