三道湾水电站引水发电洞由于受高山地形限制洞身段未做重型地质勘探,利用平面地质图推测洞身段地质现象,开挖揭露后发现存在较大差异。施工阶段根据实际揭露的围岩情况,调整开挖支护方式和衬砌断面,实施了科学合理的方案,最终满足了设计要求,其实践经验值得肯定和借鉴。

Being limited by mountain terrain,heavy-duty geology investigation wasn’t carried out in the section of tunnel body for diversion tunnel of Sandaowan hydropower station,and there is great difference discovered after excavation and disclosure using plane geology drawing to predict geological phenomenon in tunnel body.During construction period,based on actual wall rock status disclosed,excavation and bracing methods and lining cross section are adjusted,scientific and reasonable scheme is implemented,and design requirements are met,and its practical experiences are worth appreciation and drawing from.
