Abstract
This paper is based on the field investigation and collecting the existing materials,to analyze the geological environment and landslide characteristics systematically of the nine righteou-sness landslide in Nan-jiang county Bazhong city,to study the formation mechanism of the landslide according to the structure and morphological characteristics of the slope.Then it judges that the nine righteousness landslide is a traction-type soil slope,and the damage model is creep crack.At last,it analyzes the influencing factors of each condition,and makes the stability calculation by transfer coefficient method.The results show that the change of cohesion C and internal friction angle φ will influence the safety factor K.The analysis on the stability calculation shows that the overall stability of landslide is better under the natural condition,less stable in heavy rain and easy to trigger the whole sliding.The rainfall will no doubt play a crucial role to the formation and development of landslide.In order to prevent the reduction of slope stability by rainfall infiltration during the rainy season,the soil instable or local slippery deformation on the landslide,and the treat to people’s lives and property in danger areas,it suggests to carry out the geological disaster prevention and control as soon as possible.关键词
