摘要
三峡永久船闸是切岭深挖建成的双线五级船闸，最大开挖深度为170m，形成的边坡最高达160m。经过多年来国内外有关单位的研究，设计最终采用的边坡开挖坡度应使岩体基本达到自稳；地表设截、防、排水系统，岩体内部加强排水；被面进行喷钱；局部地段施加预应力锚索等加固措施，可使船闸高边坡满足稳定安全要求。
The permanent shiplocks for TGP are the twin five-stage shiplocks constructed by deep excavation in the hill with maximum depth of 170m,forming 160m of maximum high-wall slope. A careful and detailed study on the slope stability has been carried out through years. This paper summarizes this study and the measures which will be taken in keeping the slope stable.
