| Abstract: | A growing number of slope hazard and engineering case studies have shown that only one safety factor (SF) can predict landslide occurrence, but cannot identify potentially dangerous landslides, which is the major source of the most destructive landslides. To solve the problem, a safety factor of cohesion (SFc) is proposed, and an improved slope stability analysis based on two safety factors is presented. Taking a sloping rock mass as a case study, the results showed that when SFc was less than 1 and the ratio of the cohesive force to the sliding resistance force drops to less than 100%, the slope became a potential landslide. The study suggests a new method for quantitative identification of potential landslides and provides a more reliable safety evaluation index, thus can solve the difficulty of adjustment of potential landslides and provide a more reliable safety evaluation index for engineering. |
