Abstract: Dongla landslide is resurrected in Shuiluo town of Muli city. The causes of the historical experience are ancient landslide, old landslide, resurrecting landslide. Severe deformation of the landslide was since 2011, and tension cracks spread over the landslide, then generate incremental deformation sliding scale destruction. Through deformation characteristics survey and using monitor tools, slip surface is located 18.5～19.5m of the soil. The resurrection of the mechanism of landslides in the mechanical model is the slip-crack destruction. Adverse geological environment, landslide debris and loose rock and soil structure are the base of the landslide geological deformation; impact of human activities are the main factors that may influence the development of potential landslides. The landslide is currently in the stage of creep deformation severe deformation damage, and there is a trend development step by step. Landslide is likely to decline sharply in rainfall, which will destray roads and power plants and the Dongla bridge. The Shuiluo river will be blocked, bring much more damage.
