摘　　要：根据新疆某水电站发电引水系统的地形、地质条件,对发电引水洞Ⅱ类及ⅢA类(Ⅲ类偏好)围岩洞段取消常规的钢筋混凝土全断面衬砌,采用喷锚支护作为永久衬砌,缩短了发电洞的施工工期;参考以往工程经验,上游调压室取消了检修门,既可保证电站的安全运行又可减少工程投资。这些设计优化,可供类似的长发电引水洞工程参考。According to the topographical and geological conditions of a hydropower station in Xinjiang, the sections of diversion tunnel with Class II or IIIa surrounding rock are designed to be lined with shotcrete and anchor rod as a permanent lining instead of conventional reinforced concrete full-face lining. The lining optimization shortens the construction period. Based on existing engineering experiences, the service gate for the upstream surge chamber is cancelled, which can not only guarantee the safe operation of power plant, but also reduces the engineering investment. The design optimization can be as references for similar diversion tunnel.
