Abstract: Taipingxi slope was the high slope in front of dam in the Three Gorges Reservoir. If it was unstable, the new built Taipingxi migrant settlement would be threantened. According to its engineering geological conditions, it was divided into several zones by geological survey and its stability was analyzed, then different treatments were proposed based on different characteristics of different divided zones. After the treatment, it was stable. The engineering was provided as reference for similar engineering.
