| 摘 要： | 三峡库区崩滑地质灾害频发 ,其中以侏罗系易滑地层为甚。侏罗系易滑地层特殊的地层结构和岩石物理力学性质是控制崩滑灾害发生的主要因素。本文通过岩相古地理和沉积环境演变两个方面来研究三峡库区侏罗系易滑地层的沉积特征 ,并研究了三峡库区地层的沉积环境和沉积结构对岩层物理力学性质的影响 ,对三峡库区以滑坡为代表的地质灾害频发的原因给出沉积学和物理力学解释

| Abstract: | This paper describes the sedimentation characteristics of the Jurassic sliding-prone stratum in the Three Gorges reservoir area based on analyses of lithofacies paleogeography and evolution of the sedimentation environment. The authors then assess their influence on physical and mechanical properties of rock in the Three Gorges reservoir area. As such, sedimentologic causes for the frequent occurrence of geologic hazards, especially landslides in the Three Gorges reservoir area, are identified. |
