%X The aim of this research is to investigate the feasibility of non-proportional dynamic double strength reduction method in slope stability analysis. According to the 3-D progressive failure process and strength parameters of slope in ABAQUS software, the cohesion <i>c </i>and internal friction angle <i>φ</i> in Mohr-Coulomb strength criterion are converted into yield strength <i>σ</i> and internal friction angle <i>β</i> in Drucker-Prager strength criterion, and then the comprehensive stability coefficient of slope is determined through the shortest path to evaluate the slope stability. Results suggest that the non-proportional dynamic double strength reduction method based on Drucker-Prager criterion could reflect the progressive failure process and the roles of strength parameters; the slope stability coefficient obtained by Drucker-Prager criterion is highly close to that calculated by the M-C strength criterion, and the slope stability coefficient and displacement are both smaller than those of traditional strength reduction results with higher safety reserve.
