Abstract: There is an intimate connection between water and slop stability, and under the action of water, different landslides express diverse failure mechanism. Basing on the fieldwork and analysis of the Wenbituo landslide group of the Yangtse Gorges Reservoir, the work mechamism of water-rock interaction effects and the relationship between the effects and landslide were studied. The results show that:in this area,it is a maturational conditions of water-rock interaction effect that cast an important reflection on the development and evolvement of the Wenbituo landslide,by three typical action forms.

Key words: water-rock interaction effect, landslide group, destabilization, work mechanism
