摘　　要：大岗山水电站地下厂房在进行Ⅰ层开挖时,在主厂房4号机与副厂房交接处上游顶拱β80岩脉段发生塌方。通过采取前后三期系统的处理措施,并在施工过程中采用精细化管理,对施工过程进行严格控制,顺利完成了塌方段的处理,经监测数据反馈确定塌方段处于稳定状态。总结大岗山水电站地下厂房塌方处理中的程序和经验,对类似塌方处理工程具有指导和借鉴作用。In the layer I excavation of underground powerhouse of Dagangshan Hydropower Station, 1380 dyke area of the arch - top at the upstream junction zone of No. 4 unit and the auxiliary powerhouse collapsed. Through adopting treatment measure- ment in three phases as well as fine construction management, the collapse was treated successfully and the treating effects are verified by monitoring data. The treatment procedures and experiences obtained in the collapse treatment construction could be a reference and guidance for similar projects.
