Abstract
This paper evaluated the hydrodynamic and deformation characters of the Hongyanzi landslide in Pubugou hydropower station reservoir area, Sichuan province, Southwest China. The fluctuations of slope groundwater level, slope surface displacement and deep seated displacement with the fluctuation of reservoir water level were monitored. The results showed that the fluctuation of groundwater level followed the reservoir water level with two month of time lag. Approximate 0.23 to 0.25 m/day of declination rate for reservoir water level could be benefit for maintaining the global stability of the bank slope when the elevation of reservoir water level varied from 820 to 847 m. A constant head difference between the groundwater level and reservoir water level is important to the stability of reservoir slope.
