Large-scaled landslides often occur in sensitive clay deposits in horsts and grabens, typical of spreads. Most large deformation numerical analysis based on the strain-softening behavior of undrained shear strength. In practice, water infiltration into soils may result a variation of non-uniform crack and shear band emergence at a low soil resistance. In this study, the mechanism of water content effect on the stress-strain relationship was implemented in Mohr-Coulomb (M-C) model using the user material subroutine of the commercial software Abaqus/Explicit. The coupled Eulerian-Lagrangian method (CEL) was used to model such large deformation analysis. The developed model was verified by a simulation of Saint-Jude landslide, which occurred in 2010 in Quebec, Canada. There was a good agreement among numerical results with water content effect comparing to an analytical function. A larger mobile soil mass movement with a significant reduction of soil resistance was simulated successfully using the developed model.
