摘要
结合新疆大山口二级水电站Ⅱ标段引水隧洞工程地质条件,介绍隧洞开挖支护、混凝土衬砌、灌浆等施工方法,以及不良地质处理、冬季施工技术等。通过这些方法与技术的实施,工程提前3个月完工,合格率100%。
The 2nd stage Dashankou Hydropower Station is located in Xinjiang Uygur Autonomous Region. With regard to the diversion tunnel of No.II section, combined with the engineering geological conditions, an introduction was made on the construction methods of tunnel excavation support, concrete lining and grouting, treatment of unfavorable geology as well as construction technology adopted in winter. With these technology and methods, this project was completed 3 months ahead of schedule with a qualified rate of 100%.
