摘　　要：水利水电工程中引水隧洞比较常见,通风排烟对工程进度和人员职业健康至关重要,尤其超长引水隧洞随着进深加大,通风排烟效果不理想。西藏拉洛水利枢纽德罗引水隧洞根据该地域特殊性和实际情况进行周密考虑,通过分期规划,采取改善措施,解决了缺氧环境下长隧洞小断面通风排烟问题,对类似地区类似工程的设计和施工具有一定经验借鉴意义。It is common to include diversion tunnels in the construction of hydropower stations. In this case,induce ventilating and smoke exhausting system can play a significant role for ensuring schedule of construction and health of workers, especially when long diversion tunnel is getting deeper and unfavorable condition is involved. More considerations had been given to local particularities and actual conditions during the construction of Deluo Diversion Tunnel of Laluo Water Complex in Tibet. Solutions are designed to induce ventilating and smoke exhausting in small section of long tunnel under oxygen-deficient environment, which is of reference value for design and construction of similar projects.
