Abstract:: Reservoir impoundment has the important influence on the geological disasters. The reservoir began to impound in early 2008 because of the change of the water level and base level of erosion increase etc., which plays an important role in the development of geological disasters in the process of water storage. To ensure the smooth operation of the Jiudian Gorge Water Conservancy construction and normal operation after the completion, we investigated the distribution of geological disasters and their development trend after impoundment in Jiudian Gorge Reservoir based on the survey of Jiudian Gorge Reservoir area as an example. Based on the detailed survey data of the reservoir area, the geological disasters were systematically analyzed and evaluated in the reservoir area, and the influence of the reservoir impoundment on the development of geological disasters was examined. The result showed that: (1) after reservoir impoundment, it produced many bank slumps and new small-scale landslide such as collapse along the banks of the reservoir area, and the width of bank collapse was 50~100 m, which mainly distributed in the upper reaches of Taoyan; (2) there were 39 shallow and deep landslides, which induced and promoted the deformation of landslides due to reservoir water level rising in the early impoundment phase, and the reservoir water level has a little effect on landslide stability due to the most of landslides locating below the water or far above the water level; (3) the reservoir impoundment has the impact on the development of landslides at a large degree, and has a little influence on original flow gully development, the flow gully is mainly induced by rainfall.
