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

摘要： 滑坡的发生与水有密切的联系,不同的滑坡在水的作用下表现出不同的破坏机理。通过对三峡库区文笔沱滑坡群的实地考察和对现有资料的分析,探讨了该地区水岩作用机理及其与滑坡之间的关系。分析结果显示,该地区水岩作用条件成熟,具有3种典型的作用形式,它们对文笔沱滑坡群地质灾害的诱发和形成有重要影响。
