摘　　要：龙滩水电站地下厂房洞室群支护采取工程类比、理论计算及现场监控的多种方法进行设计。针对中陡倾角层状岩体上、下游边墙的变形特征不同、潜在不稳定体出现部位的区别,提出了上、下游边墙预应力锚索重点加强部位有所区别的支护设计方案。The methods such as project analogue, theoretical calculation, and on-the-spot monitoring have been adopted in the support design of the surrounding rock masses of the underground powerhouse of Longtan Hydropower Station. The different pre-stressed anchorage support schemes for different key positions in the upstream and downstream side-walls have been put forward, in accordance with the conditions that the stratified surrounding rocks with medium and steep dip angles, different deformation characteristics, and the locations of different potential unstable bodies.
