摘　　要：隔河岩电站引水隧洞环锚预应力衬砌结构为国内首例，以下介绍了该工程隧洞衬砌的设计情况。这一实践为大直径、高水头压力隧洞衬砌设计创造了新途径。研制成功的环锚（ＨＭ）系统已在该工程中应用，实现了无台座张拉施工。The prestressed ring shaped anchorage cable lining structure of intake tunnels at Geheyan power station is the first example in China.This paper presents the lining design of the tunnel. The developed ring-anchorage-cable system had been applied in this project,realizing the prestretching process without operating platform. This new technology is suitable to prestressed circular conduit both above and under ground, and has considerable economic benefits. It is worth while to recommend its application.
