Forecasting of Jiatanchang Bank Collapse in the Three Gorge Reservoir Area

In the reservoir storage and operation process, the geological environment of reservoir bank will change significantly; the changes often cause some geological problems, such as landslide, reconstruction of reservoir bank etc. In this paper, Jiatanchang reservoir has been taken for example, under the premise of engineering geology and stability analysis, Kachugin Method was applied to forecast bank collapse; combining with urban planning and ecological protection, the corresponding protective proposal has been put forward.
