Abstract

Abstract:

Based on finite element method ABAQUS and strength reduction theory, the numerical simulation and sensitivity analysis of the soil slope with and without reinforcement were conducted. The influence of geometrical parameters of slope, strength and stiffness of soil, permutations and combinations pavement of geogrids on the slope stability was studied. The results suggested that soil cohesion had the most obvious impact on the safety of slope, and that other factors like soil internal friction angle, slope angle, permutations and combinations of spacing of geogrids were also significant in affecting the safety of slope. It was noted that when geogrids buried across the potential sliding surface (the plastic region of unreinforced slope), the displacement of slope could be confined obviously and the slope stability could get improved efficiently.

Key words: strength reduction theory, numerical simulation, sensitivity analysis, slope stability, safety factor
