Abstract: Slope excavation and processing is critical in the design and construction of water conservancy and hydropower project. It exerts directly impact on the safety of construction and operation. Combined with Chushuidong reservoir, using the software Slide and STAB-EMU, analysis and comparison of the stability of excavated slope of the pumping station, dam plinth and spillway were carried out. The result showed that the slope would be on the safe side with appropriate engineering measures and the safety requirements would be met. The whole process was worthy of reference.
