摘　　要：三峡大坝三期蓄水后坝前水位为135m,忠县陶家石盘以下为常年库区河段,航道水深较天然状况下大幅度增加,库区将面临深水设标的诸多问题。由于三峡水库落差大、回水深、淹没范围广,目前尚无类似可借鉴的深水航道设标经验。本文基于一定的理论分析基础,通过试验论证,取得了深水设标的一些经验和方法,也为三峡156m、175m蓄水后的航标设置奠定了一定的基础。After Phase III water impoundment, the dam front water level of Three Gorges reaches 135m. Since the reach from the dam to Taojia-Shipan in Zhongxian County is a perennial reservoir, the channel depth increases observably comparing with that under natural condition, thus we face multiple problems concerning deepwater navigation mark establishment in the reservoir. Because Three Gorges Reservoir is characterized by sharp fall of water, great depth of backwater and broad range of submerge, there is no experience of navigation mark establishment for deepwater channel yet. Based on both theoretical analysis and experimental demonstration, we achieved some experience and methods for navigation mark establishment in deepwater channel. This has laid a basis for navigation mark establishment of Three Gorges at levels of 156m and 175m.
