水电站装机容量215 MW,在冰岛东部,距埃伊尔斯特城30 km,估计价值1亿美元,1991年5月定合同。工程有一条31 km长、5 m直径的引水隧洞,其中3 km用钻爆法开挖,2 km进口和支洞也用钻爆法开挖,其余28 km主硐将用TBM掘进。厂房硐挖方29,250 m~3,尾水隧洞长1.2 km,高7 m,宽5.3m,马蹄形断面、用钻爆法开挖。
The installed capacity of the hydroelectric power station is 215 MW, which is estimated to be worth 100 million U.S. dollars in the eastern part of Iceland and 30 kilometers from the city of Eyre. The contract was agreed in May 1991. There is a diversion tunnel of 31 km in length and 5 m in diameter. Among them, 3 km is drilled with the method of drilling and blasting, 2 km of inlet and branch holes are also drilled with the method of drilling and blasting, and the remaining 28 km of main tunnels are borned with TBM. The excavation site of the workshop is 29,250 m 3, the tailrace tunnel is 1.2 km long, 7 m high and 5.3 m wide. The horseshoe-shaped section is excavated by drilling and blasting.
