截至2017年3月7日,世界上规模最大的内河船闸——三峡船闸累计过闸货运量突破10亿吨。三峡水库蓄水后,库区100多处主要险滩被淹没,加之航道整治工程的实施,库区通航条件得到了很大改善,大部分单行控制河段被取消,绞滩站全部被撤销。重庆至宜昌河段水深为4.5米以上的航道长达548千米,一年中有半年以上可以通行5000吨级单船和万吨级船队。 As of March 7, 2017, the accumulated volume of over-lock in the Three Gorges Lock, the largest inland waterway lock in the world, exceeded 1 billion tons. After the impoundment of the Three Gorges Reservoir, more than 100 major rapids in the reservoir area have been inundated. With the implementation of the channel regulation project, navigable conditions in the reservoir area have been greatly improved. Most of the single-control river sections have been canceled and all of the stations have been canceled. The passageway from Chongqing to Yichang reach a depth of 4.5 meters up to 548 kilometers. In the past year, more than half a year can pass 5,000-ton single-vessel and 10,000-tonnage fleets.
