| 摘 要： | 三峡工程枢纽泄洪产生水面波动和船闸泄水产生非恒定流,对下游引航道通航条件,尤其是对升船机的运行构成影响。泄洪在口门区及连接段产生的斜流对通航的影响很大,采用斜流的特征值并结合船模航行的斜流效应特征值,有效地分析了口门区及连接段的通航水流条件。采取修改航线措施对改善斜流影响有一定的效果。

Navigation Conditions of Downstream Approach Channel of the Three Gorge Project |
| |
| Abstract: | The surface wave during the Tree Gorge Project(TGP) flood discharging and the unsteady flows during the lock emptying has influence on the navigation of downstream approach channel,and especially on the shiplift running.Oblique flow formed in the downstream approach entrance and connect region during TGP flood discharging influenced the navigation greatly.By the characteristic values of the oblique flows and characteristic values of the ship sailing in oblique flows,the navigation flow conditions are analyzed effectly.The influence caused by oblique flow will be reduced through modifying the navigation line. |

| Keywords: | approach channel entrance region connect region oblique flow unsteady flow |
