Mio Xiangsheng ( Xi'an College of Geology )
Based on the data obtained through an investigation on the Liujiapo landslides at the Langao County, Shaanxi Province, this paper discusses the nature-geological environment, the hydrogeological and engineering-geological conditions, and analyses the main faotcrs which influenced the landslide formation.The paper consideres that the basic reasons of the landslide formation are. ( 1 ) the physite-mylonite has been acted as the sliding bed here, and ( 2 ) the places between the sliding bed and the sliding mass have sufficient groundwater. Lastly, the paper puts forward some rationalization proposals on the prevention and the harnessing of these landslides.
