Macroscopic Criterion of Identifying Potential Bedding Plane Rock Landslides in the Three Gorges Reservoir Region

How to accurately identify the potential landslides is a current technical challenge. In recent years, early detection of potential catastrophic geohazards with integrated remote sensing technologies is in the ascendant, but those without obvious deformation and geomorgraphic characteristics cannot be detected. For many years, a number of practices have been conducted on the prevention and control of geohazards in the Three Gorges Reservoir, hence there are research basis for bedding plane rock landslides as well as new typical landslides examples occurring after reservoir impoundment available for analysis. Therefore, on the basis of previous research results and study of river geomorgraphic evolution in the Three Gorges Reservoir, this paper analyzes the special geological conditions of Qianjiangping landslide, Shanshucao landslide and Kamenziwan landslide, and bringsVaiont landslide and Tangyanguang landslide outside the region into comparison, so to put forward the macroscopic criteria for potential bedding plane rock landslides in the Three Gorges Reservoir, including tectonic position and movement, slope structure, landslide prone stratum and geomorgraphic form. With the criteria, we would be able to analyze indoor data and investigate the phenomenon on-the-spot, then accurately delineate the scope of those potential landslides, and bring them into the monitoring and early warning system, in order to prevent and control the geohazards more timely and effectively.
