长江三峡库区崩滑地质作用受岩石圈深层结构、表层地质构造和地貌新构造 3个层次因素的制约 ,构造 -岩性 -地貌组合条件控制着崩滑地质灾害的形成与分布。库区北东向的弧形构造控制了大型崩滑体的集中分布地段。库区大型崩塌主要发生在背斜核部厚层灰岩陡崖分布地带 ;大型滑坡主要发生在侏罗山式向斜槽部边缘软弱岩层形成的岸坡地带 ,并可归纳为 4个构造岩性结构类型。在此基础上对库区两岸大型崩滑体易发区段进行了划分和预测。
The slide-slip geology of the Three Gorges reservoir area is controlled by three levels of lithosphere deep structure, surface geological structure and new geomorphology. The combination of structure, lithology and geomorphology controls the formation and distribution of the landslide-prone geological disasters. The north-east arc structure in the reservoir area controls the concentrated distribution of large landslides. Large-scale collapse in the reservoir area mainly occurs in the thick limestone cliffs of the anticline core; large-scale landslides mainly occur in the bankland zone formed by the soft rock strata along the margin of the Jurassic syncline and can be classified into four tectonic rocks Sexual structure type. Based on this, the large-scale landslide-prone areas in the two banks of the reservoir area are divided and predicted.
