| Abstract: | The power tunnel of Jinhe-2 hydropower station is 1986m long, and the floor gradient is 0.001. It is a roundsquare free-flow tunnel. After tunnel lining, it is 2.5m in width and 2.7m in height. The article briefly presents geological engineering and construction conditions of the tunnel, and it could be a reference to the construction of other similar small hydropower station. |
