摘　　要：抽水蓄能电站地下厂房高达50多米,需要利用通风兼安全洞和进厂交通洞进行自上而下开挖,通风兼安全洞、地下厂房、进厂交通洞均位于工程施工关键线路上,研究缩短地下厂房施工工期的方案是必要的。通过对某抽水蓄能电站钻爆法和TBM施工方案进行比选和优化,以优化地下厂房施工工期为出发点,研究TBM开挖线路、厂房TBM开挖及扩挖方案等内容。采用TBM施工较常规钻爆法施工可提前8个月完工,可使抽水蓄能电站提前发挥效益,为后续抽水蓄能电站工程开挖技术提供借鉴。The underground powerhouse of a pumped storage power station extends to a depth of over 50 meters and requires top-down excavation using a ventilation and safety tunnel as well as an access tunnel.The excavation of the ventilation and safety tunnel,the underground powerhouse,and the access tunnels are all critical paths in the construction process.Therefore,it is essential to develop strategies to shorten the construction period of the underground powerhouse.This study compares the drilling and blasting method with the Tunnel Boring Machine(TBM)construction scheme for a pumped storage power station.Focusing on optimizing the construction schedule of the underground powerhouse,the research investigates the TBM excavation alignment,the TBM excavation process for the powerhouse,and expansion excavation schemes.The findings indicate that utilizing the TBM method can accelerate project completion by eight months compared to the conventional drilling and blasting method.This acceleration allows the pumped storage power station to commence operations earlier and provides valuable insights into excavation technologies for future pumped storage power stations.
