Causes and Stability Analysis of Landslide in Road Emergency Rescue

In order to explore the cause of the emergency rescue of landslide, the comprehensive analysis of internal and external factors of the landslide has been carried on. The results of research show that landslide disaster is happened under the condition of unfavorable landform and the multiple influences of various factors, including heavy rains leading to reducing of the strength of rock and soil and the slope toe being disturbed by human engineering activities. Calculated results of stability analysis are in keeping with the local deformation phenomenon, which is the precondition of treatment for the landslide.
