【 摘 要 】

Based on the characteristics of loess landslide under earthquake action, in order to more accurately and reasonably evaluate the stability of loess landslides under earthquake action, considering the systematicness and scientificity, a reasonable loess landslides under earthquake action stability evaluation index system has been set up, and a fuzzy comprehension evaluation model for the stability of the loess landslide under earthquake action was established to evaluate its stability. This model has been applied to Sanjiadi landslide in Gansu province to analyze the stability of loess landslides under earthquake action; the stability coefficient of the Sanjiadi landslide under earthquake action was calculated by use of the pseudo-static method. Both methods indicated that the Sanjiadi landslide under earthquake action was in an unstable state; and the results are reasonable and confirm to reality.
