Abstract: Wudongde Hydropower Station is the most upstream cascade hydropower station among the four giant cascade hydropower stations in the lower reaches of Jinsha River(from Panzhihua to Yibin City).There is a natural Karst inclined shaft, K25 Karst cave, near the right dam abutment.In order to solve the problem, the design team uses the K25 Karst cave to arrange the centralized control building after special research, which can effectively avoid the risk of high slope rock-fall and create a safe and comfortable operation and maintenance environment.It is also conducive to make full use of the natural environment in the construction area, reduce the occupation and interference to right dam abutment construction site where is narrow, and reduce the concrete backfill, thus saving the project investment.The design concept of centralized control building is derived from the natural form of "water flow flying" when the dam flood discharge facilities work, which has the beauty of flexibility and strength.Through innovative architectural design, K25 Karst cave centralized control building has become a beautiful landscape of the Wudongde Hydropower Station.The results can provide new ideas for similar engineering design.
