锦屏二级水电站引水系统关键技术问题

Study on Key Technical Problems for Constructing Jinping Ⅱ Hydropower Station

锦屏二级水电站目前是世界上规模最大的引水式电站之一,许多重大技术难题已超出了现有的认识水平。雅砻江流域水电开发有限公司组织参建单位开展了一系列地下工程关键技术研究,在岩爆防治、地下突涌水处理、软岩洞段施工、施工通风、TBM法和皮带运输系统等方面取得了丰硕的成果,为工程按期投产发电奠定了坚实的基础。

Jinping Ⅱ Hydropower Station is one of the largest diversion power plants in the world, and a number of major technical difficulties encountering in construction has gone beyond existing knowledge. A series of key technical researches on underground engineering are carried out by engineering contractors organized by Yalong River Basin Hydropower Development Company. The researches on prevention of rock burst, treatment of sudden groundwater gushing, construction technique for soft rock, ventilation, TBM method and belt transportation system have achieved a large number of results, which has laid a solid foundation for on-schedule electricity production of Station.
