Stability Assessment of Water-Influenced Landslides in the Three Gorges Reservoir Area: A Case Study of the Liujiabao Landslide

The Three Gorges reservoir area is a high incidence of landslide disasters, many landslide development law and its influencing factors are not clear, and due to the Three Gorges reservoir area for a long time by the Yangtze River water level changes, rainfall infiltration and groundwater and other factors, resulting in landslide destabilization and deformation damage in the reservoir area, the threat to the people's lives and properties, so to identify the stability of the landslide of the Liujiabao not only for the future of the study of this type of landslide to provide a theoretical basis, but also for the prediction of some potential landslides has very important significance in guiding.This paper combines the regional geological background with the results of the actual field investigation, using the transfer coefficient method to evaluate the stability of the landslide, the stability evaluation results are: 2-2 profile is now in a stable -basically stable state, the possibility of destabilization is relatively small.1-1 profile in the reservoir water level rose to 175m and there are heavy rainfall conditions, the stability evaluation results are: 1-2 profile in the reservoir water level rose to 175m and there are heavy rainfall conditions, the possibility of destabilization is relatively small.1-1 profile is unstable under the condition of 175m and heavy rainfall, and the rest is stable-basically stable.
