摘　　要：船舶吨位提高、大型港口作业区发展需要提升长江上游九龙坡—朝天门河段航道等级。为满足这一需求,通过物理模型试验研究九龙滩航道整治方案,使该河段航道尺度由Ⅲ级(2.7 m×50 m×560 m,水深×航宽×弯曲半径)提升为Ⅰ级(3.5 m×150 m×1000 m)。分析工程实施后的效果得出:1)九龙滩滩段整治后航道尺度满足设计要求,航道条件趋近一般航道,航宽足以正常会让船舶。2)彻底解决了九龙滩滩段弯曲、狭窄、水流急的状况,水流由以前的泡漩状态改善为现在的稳流状态。3)船舶明显更易控制,通过弯道更加安全。The increase in ship tonnage and the development of large-scale port operation areas need to upgrade the level of the waterway from Jiulongpo to Chaotianmen in the upper reaches of the Yangtze River.In order to meet this demand,the Jiulongtan waterway regulation plan is studied through physical model tests,so that the waterway size of this section is upgraded from level III(2.7 m×50 m×560 m,water depth×navigation width×bending radius)to level I(3.5 m×150 m×1000 m).Through analyzing the effects of the project implementation,it is concluded that:1)After the regulation of the Jiulongtan beach section,the scale of the channel meets the design requirements,the channel conditions are close to the general channel,and the navigation width is sufficient to allow the ship to operate normally.2)The situation of bending,narrowness and rapid water flow in the beach section of Jiulongtan is completely solved,and the water flow is improved from the previous swirling water to the current steady flow state.3)The ship is significantly easier to control,and it is safer to go through bends.
