| 摘要: |
| 用二维浅水有限单元对邵仙水利工程多建筑物的河道水流进行了数值模拟，在对隔水墙及系船墩进行简化处理后，闸的两种运行工况下的计算结果表明，隔水墙可平顺进闸水流；新建系船墩对通航不利。 |

| Abstract: |
| Water flow with multiple structures in Shaoxian hydro project was numerically simulated by using a 2-D finite element method. The diverting wall and dolphins were simplified, and calculation results of two operating manners show that the diverting wall can smooth entrance flow while new dolphins are unfavourable to navigation. |
