Abstract: Fill-type dams for power generation and irrigation purposes have often experienced severe damages of slope failure due to a rapid draw-down of the reservoir water in seasons of full operation. This paper concerns seepage flow behavior in earth slopes and distribution of pore water pressure in the dam body and their influence on slope instability, due to a rapid draw-down of the reservoir water. Centrifuge model tests were carried out on several model earth fills to discuss and propose an appropriate procedure of stability evaluation of slopes. The test results and stability analysis showed that the residual pore water pressure generated in the dam body due to a rapid-draw down of the reservoir water has a serious influence on slope stability.
