摘要
福堂水电站圆筒阻抗式调压井开挖直径31.0m,衬砌后直径27.0m,井深117.7m,是目前世界上已投产的开挖直径最大的开敞式调压井工程,工程地质条件极差,施工安全问题比较突出。福堂水电站调压井施工中采用的岩体预加固技术、安全施工技术及监测技术,可供同类工程参考。
The excavation diameter of cylinder surge tank of Futang Hydropower Station is 31.0 m and after lining, its diameter is 27.0 m. The depth of tank is 117.7m, the largest one in diameter in the world under operation. The geological condition of the project is worse, and the construction safety problem is quite prominent. In the construction of the surge tank of Futang Hydropower Station adopted the rock pre-reinforced technology, safe construction technique and monitoring technique, which can be used for reference in similar projects.
