Stability Analysis of Backfilled Gravel Subgrade Slope with FEM Strength Reduction

Abstract:

Article Preview

The current study was implemented to evaluate the backfilled gravel subgrade slope stability of a highway, China. Typical crossing section in Jiling Province was evaluated by using the finite element based strength reduction method. The calculation code was developed based on BCF, which was programmed for 2D finite element analysis on soil stress-strain analysis. The Duncan-Chang nonlinear constitutive model was employed to describe the stress and strain relationship of the soils. The safety factor calculated by the strength reduction method was compared with traditional limit equilibrium slice Bishop Method.
