This paper introduced the construction of the pumped-storage power station (PSPS). In the excava- tion of underground power house, the principle of excavation in thin layer and support in time with real time monitoring are adopted. The excavation blasting parameters are adjusted timely. Through these, the excavation quality can be guaranteed, the surrounding rock can be prevented from being damaged and the deformation of power house side wall can be controlled. Five security defense lines have been adopted to solve anti-seepage and drainage in the major underground projects.
