Abstract: Excavation of underground powerhouse and support is crucial to control the construction period of Xianyou pumped storage power station project. The paper summarizes the experience of excavation of underground powerhouse in aspects such as excavation procedure and method, support method, quality and time limit and et al. As well, the paper stresses on the contents of the distribution of underground construction tunnels and layered excavation, time limits and input resources for excavation of different layers, disturbance of excavation on surrounding rocks and their deformation. Further, the main influence factors in excavation construction are pointed out and the suggestions for improvement are presented, for reference.
