摘要
引水隧洞为吉牛水电站的关键工程,隧洞沿线地质情况差、云母含量高,致使隧洞开挖单循环进尺短。为提高洞内施工的效率,经综合考虑,确定在吉牛水电站引水隧洞工程全线推行隧洞开挖与混凝土衬砌平行作业施工技术,取得了较好的效果。
Headrace tunnel is the key project of Jiniu hydropower station. Because along the tunnel line,the geological conditions are poor and mica content is high,leading to slow single cycle advance for tunnel excavation. Therefore,in order to improve construction efficiency in the tunnel,it is decided to adopt parallel operation of excavation and concrete lining along whole headrace tunnel at Jiniu hydropower station.
