摘要
吉牛水电站属围岩富含云母超长引水隧洞电站工程,且堆石混凝土首次在大坝工程中应用。对吉牛水电站大坝深厚覆盖层基础处理及堆石混凝土应用、富含云母软岩引水隧洞施工几个关键技术问题与对策进行了阐述,可供同类工程参考和借鉴。
At Jiniu hydropower station,the surrounding rocks of the super long headrace tunnel are mica-rich and rock-filled concrete is first used in dam construction. In this paper,several problems,such as foundation treatment for thick overburden below the dam,rock-filled concrete application,construction in headrace tunnel in soft surrounding rocks with rich mica are described to provide references and experiences to the similar projects.
