The natural and geological environment of Longdanxi Landslide was introduced and then its formation conditions and main control factors were analysed. The rugged and rough landform. loose talus materials. abundant precipitation and highway excavation are the main factors that caused the old landslides revive. The occurrence mechanism of it is:Front edge dege fractured and deformed whole sliding. Based on formation condition of the landslides, this paper put forward that landslide prevention may use the synthetical control measure combining draindge, support and retaining wall with anti-dust works: In this paper,the programs were compared as well as the feasibility and safe degree were analysed.
