摘　　要：仰山三级电站引水隧洞为不衬砌隧洞,只在弯道段和岩体破碎段进行了全断面衬砌。文中介绍了不衬砌隧洞糙率的计算方法,并根据原型观测资料得到仰山三级电站引水隧洞不衬砌段的实际糙率。The access tunnel of Yangshan three-stage hydro-power plant is lined around the tunnel at bends and reaches of rock rupture but is nonlined at other reaches. In this paper, a computing method of the roughness on nonlined tunnels is presented, and the real roughness on the access tunnel of Yangshan three-stage hydro-power station is obtained based upon the original observed data.
