| Abstract: | The key works of the Mianhuatan Hydropower Station includes the RCC gravity dam, open crest spillway, flood releasing bottom outlets, conveyance structure, underground powerhouse, power distribution setup in the tunnel, control building, and navigation structure. The project is a Rank 1 project and its dam is a Grade 1 structure. The RCC dam has the maximum height of 110 m and the crest length of 308.5 m. There are three crest spillways each with the width of 16 m. The bottom outlets are arranged in No.7 dam section. There are 4 power generation tunnels each with the diameter of 7.5 m. These tunnels are 169.8 184.5 m long. The dimensions of the underground powerhouse are 129.5 m long, 21.9 m wide and 52.08 m high. Four hydro generating units are installed in the powerhouse. The power generation of the first unit proved that the design of the general layout of the project is reasonable. |
