Abstract:Chuanshan landslide is a typical low and gentle rock slope. Its natural inclination angle is 15°–17°,and its sliding surface angle is 8°–15°,which is singular in calamity of sloping field. It shows that the low slope is not always safe in highway slope design,and geology governs the slope stability. It has taken AO technology to translate the map with scale 1∶2 000 into the intuitionistic 3D landform,and the property and stability of landslide are researched. Theory of finite difference method has been used to analyze elastic stabilizing pile and integrative design of both calculation and CAD technique,which are credible decision-making for landslide prevention measures.
