三峡库区乌江河口航道整治

Study on Wujiang river estuary channel regulation in Three George reservoir district

通过对模型试验成果的分析可见,三峡成库后乌江河口段泥沙累积性淤积,河床普遍淤高,将对该河段的航道、港口等带来极为不利的影响,经采用整治建筑物调顺河道岸线、缩窄江面宽度、加大水流流速,从而起到了减少泥沙淤积、缩小边滩、稳定航槽的明显效果,改善了乌江河口段航道及港口通航条件。

Based on the analysis of the research achievements of model experiment in Wujiang River estuary, it was indicated that sediment would deposited accumulatively, the bed became higher, the navigation channel and port would be worse influenced. After the regulation work adopted,the bank-line is straightened,the waterway width is narrowed, the ship velocity is accelerated, sediment deposition decreased,the beach reduced, and the channel stabilized and the navigation condition is optimized also. 
