    GEOLOGICAL STUDY ON THE BAIYIAN LANDSLIDES IN THE THREE-GORGES RESERVOIR AREA

    • 摘要: 白衣庵滑坡是一个由古滑坡、老滑坡和新滑坡组成的滑坡群,是川、峡二江在奉节东西贯通形成统一的长江后,三叠系巴东组(T2b)地层在江水强烈下切侵蚀事件的持续作用下导致江岸斜坡逐渐卸荷、倾倒、崩塌和表层滑坡等多期作用形成的古崩滑体。

       

      Abstract: The Baiyian landslides are located in the left bank of the western termination of the Three-Gorges Changjiang River. They are ancient landslides, old landslides, and young landslides formed by the strong incision of the river after the Chuan and Xia rivers joined up to form an unitfied Changjiang River. The bank-slopes composed of the Triassic mudstone and limestone have undergone a complex process,inclinding gradual unloading toppling collapse and sliding. It is clear that the stability of Baiyi an landslides is different, the ancient landslide to be stable, some parts of the old landslides are unstable due to the 145m~175m water level change of the Three-Gorges reservoir and the young landslides on the surface layer maybe unstable in sustaining rainstorm. Finally, the engineering suggestions of control on landslides are put forward in this paper.
