| 摘 要： | 本文讨论了三峡引航道的冲沙方式和提高冲沙效率的措施。建议在冲沙闸的基础上，增加一条流量为1500m3/s的竖井式冲沙隧洞，同时，通过航道维护手段，控制冲沙水流，提高效率。建议三峡工程采用4000m3/s冲沙流量；汛期和汛末两次冲沙，分别冲刷上游和下游引航道，必要时小幅度降低三峡和葛洲坝库水位帮助增加冲沙效率，在航道边角和口门外，采取挖泥方式清除剩余淤积。

| Abstract: | A scheme is proposed to enhance the flushing efficiency of the lock approach of the Three Gorges Project(TGP).The scheme includes the construction of a shaft tunnel to increase the flushing discharge,reasonable arrangement of flushing season and dredging of the residual deposit at the entrance.In case of serious sedimentation cause by heavy flood,the water level of TGP and Gezhouba reservoir should be lowered to enhance the scouring efficiency. |
