摘要
为解决三峡水利枢纽地下电站洞室群因埋深浅、山体单薄、块体强发育、洞室规模大、起吊重量大等特点带来的各类关键技术问题,在工程建设过程中进行了多项联合攻关,研究出“稳定拱”设计理论、“单洞型布置”、钻孔彩电技术及可视化偏录等多项创新成果,确保了工程的顺利建设,为类似工程积累了宝贵经验,具有一定工程意义和推广价值。
In order to solve all kinds of key technical problems caused by the characteristics of shallow burial depth,thin mountain body,strong block development,large cavern scale and large lifting weight in the cavern group construction of the Three Gorges underground power station,a number of joint tackling key problems were carried out in the process of project construction,a number of innovative achievements were proposed,such as"sta⁃ble arc"design,single hole layout,drilling colour television technology and visual catalog,which ensured the smooth construction of the project,accumulated valuable experience for similar projects,and had important engi⁃neering significance and popularization value.
