Abstract

Abstract

The stability of the slope with arc-shaped slip surface was studied based on the gradient-dependent non-local friction model and the gradient-dependent non-local material parameters were discussed. The material parameters, influence on the safety factor of slope stablity was analyzed from a microview with the mechanism of macro engineering problems probed. It is found that, when the non-local material parameters with microscopic properties change, the change of the slope safety factor will be not so big, but the trend will be very obvious. To discuss the influence of soil parameters on the safety factor, the gradient-dependent non-local friction model was compared with the local friction model, and the safety factor was found to be sensitive to the soil internal friction angle. The results provide useful reference for the engineering of soil slope treatment.
