广西贺州市水晶塘水电站无压引水隧洞的施工方案,根据地形地质条件,洞线采用折线方案,设置较多的支洞以便于施工及通风,采用光面爆破开挖、喷锚支护进行隧洞的施工,该方案具有施工速度快,效果(益)好等优点。

According to the topography and geology condition, the construction scheme of the diversion tunnel of the Shuijingtang hydropower station was determined, The hole line uses broken line scheme and laid out more branch holes for construction and draft.
