Abstract: The relocation sites of population from the Three Gorges Project site are in a complicate geo-environment in which the land is insufficient to construct.There ecists high risk to utilize the hazardous geomass, such as landslide though it may be stabilized.But this is very realistic subject. The pre stressed anchoring piles aere used to controll large-scale landslides and creat flats to build. The loose filling and sliding mass is reconstructed with cement grout that can greatly decline the price for foundation and slope stabilization. Excavation waste materials can also affect the course of the Yangtze River and the relocation sites by man-made sliding and debris. The fabric retaining wall with height, 57m in maximimum, is build to store the waste material and makes the land suitable to relocation.
