| Abstract: | Shaft excavation is the normal construction project in hydropower stations, and the shaft excavation in weak basement is especially difficuh. Combining the surge shaft surrounding rock situations and construction arrangement in Yongning River Level 4 Hydropower Station, the excavation and support construction plan of the shaft under weak basement conditions is elaborated comprehensively in this paper in a bid to provide the reference for similar shaft project construction. |
