摘要：
白莲河抽水蓄能电站在引水系统共布置2座阻抗式调压井。竖井为高程233.100~319.000 m,总高度85.9 m。调压井井挖采用"先导井,后扩挖"的施工方法。施工中选择合理的爆破参数、出渣方法和及时的支护,保证了安全施工和开挖质量,取得了较好的经济效益。
Abstract：Within the water diversion system of Bailianhe Pumped Storage Hydropower Station,two restricted orifice surge shafts are arranged,of which the elevations are 233.100~319.000 m with the total height of 85.9 m..For the excavation of the shafts,the construction method of "excavating pilot shaft first,and then enlarging it" is adopted with reasonable blasting parameters and mucking method as well as instant supporting.Therefore,the excavation quality and safe construction are ensured with better economic benefit.
