| 摘 要： | 三马山小区巴东组三段泥质灰岩由于岩溶溶蚀作用已全部发生了变形 ,根据变形程度的差别 ,可将变形区分为三个地带 ,即上部轻度溶蚀沉降地带 (Ⅰ ) ,中部溶蚀沉降地带 (Ⅱ )和下部沿江滑坡 (Ⅲ )。建筑设施主要分布在中部溶蚀沉降地带 ,应注意防水。下部沿江滑坡治理难度大 ,不适于移民迁建。

| Abstract: | Because of the karst dissolution, the argillaceous limestone of the 3 rd member of middle Triassic Badong Formation (T 2 b 3 ), has been deformed in Sanmashan resettlement area of Fengjie County, Three-Gorge Reservoir region. On the basis of the deformation intensity, 3 different deformation zones are identified. They are slight dissolution-subsidence zone in the upper part(Ⅰ), dissolution-subsidence zone in the middle part(Ⅱ), and bank landslidein the lower part(Ⅲ). The dissolution subsidence zone(Ⅱ)is a main resettlement zone and should be kept off water. The bank landslide zone is difficult to control the slide and the resettlement buildings must be set away from there. |
