Abstract: According to the characteristics and distribution of layered rock mass high-cut slope, the four failure models was proposed, which included weathering erosion of slope, erosion of slope toe, consequent sliding and collapse. Then the related protection was proposed, which was as the reference for the guideline of layered rock mass high\|cut slope in the Three Gorge Reservoir.

Key words: Three Gorge Reservoir, layered rock mass, high\, cut slope, engineering protection
