摘　　要：通风排烟是水利水电工程地下厂房洞室群施工过程中的重难点之一。由于地下厂房洞室群断面尺寸大、施工支洞数量多、长度长、进口少、分岔多,因开挖工作面交叉作业,其与大气相通的通道较少,故在施工过程中保持通风则较为困难。针对水利水电工程地下厂房施工过程中通风系统复杂的情况,采用现场调研、数值模拟等方法,以期为同类工程地下洞室群施工过程中的通风系统提供借鉴和参考意义。Ventilation and smoke exhaust are one of the key and difficult points in the construction process of underground powerhouse caverns in water conservancy and hydropower projects.Due to the large cross-sectional size,numerous construction support tunnels,long length,few entrances,and numerous branching tunnels of the underground powerhouse cavern group,as well as the limited access to the atmosphere during excavation work,it is difficult to maintain ventilation during the construction process.In response to the complex ventilation system during the construction of underground powerhouses in water conservancy and hydropower projects,methods such as on-site investigation and numerical simulation are adopted to provide reference and guidance for the ventilation system during the construction of similar underground caverns.
