According to .investigation of the landslide characteristics caused by the Yushu earthquake, Yushu earthquake landslide has characteristics as following strong control action of surface rupture, intensive piece distribution ,and mainly collapse accumulation landslide. Analysis of the landslide by engineering activities, surface water infiltration, seismic vibrations affect driving landslide mechanism-based cable, anti-slide pile engineering remediation measures.Keywords: Yushu seismic characteristic; landslide; characteristics; formation mechanism; control measure
