Research on Slope Deformation Regularity of the Badong Formation in the Three-Gorges Reservoir Area
The Three-Gorges Reservoir area is characterized by widely distributed strata of Badong Formation, in which large size landslide and deep-reaching loose geological body are likely to form. Therefore, it is significant to reveal the mechanism and patterns of the large size landslide in Badong Formation for better understanding of the development of the nature of deformation and process of formation of the deep-reaching loose stratum slope. In this paper, the geological characteristics of the rock mass of the Badong Formation are concluded on the basis of systematic explanation of the space variation of the lithology combinations and space variation of structural deformation of the Badong Formation in the Three-Gorges Reservoir area. To demonstrate the basic law of long-term deformation of the Badong Formation slopes and the patterns of later stage reform and landslide evolution, the authors exemplify the Huangtupo landslide that is typical in the Badong Formation.
