摘要
Abstract
In order to solve the difficulties of the double shaft of Lawa Hydropower Station,such as small oper-ating space,large vertical height,large excavation size,small thickness of rock mass between the shafts,high al-titude,complex environment and high safety factor requirements,the blasting design was optimized by adopting the method of integrating reasonable mechanization technology and optimized traditional technology in the con-struction process,and the construction technology of ultra-deep shaft excavation and support was formed and summarized,which ensured the fast,safe,high-quality and efficient construction of the thin-walled shaft of the double gate chamber in the high-altitude area.The experience can provide an important reference for similar shaft excavation and support projects in many fields such as pumped storage power stations,tunnel transporta-tion,mine construction,and has a wide range of utilization value and application prospects.关键词
