The tentative evaluation of the project for the prevention and control of the large landslide disasters in the Three Gorges Reservoir area

With the large landslide disasters in Three Gorges Reservoir area as the study object, this paper has summarized and analyzed totally 72 control engineering projects used for tackling the disasters. The characteristics of prevention technology for large landslide disasters in the area are summed up. Through the analysis of the basic types and characteristics of the control engineering projects for the large landslide disasters in the Three Gorges Reservoir area, an evaluation index system for the control engineering measures against the large landslide disasters has been established, and the effects of the control project against the landslide disasters are classified in accordance with the evaluation index and standard.
