| 中文摘要: |
| 针对弯曲河段航运枢纽船闸上游口门区出现大范围回流漩涡、引航道存在斜向流等不良流态的工程问题，采用正态整体水工物理模型试验的方法，对泄水闸不同调度方式对凸岸船闸上游引航道及口门区通航水流条件的影响进行研究。结果表明：对于船闸建在凸岸的航运枢纽，泄水闸开启远端闸门的调度方式可有效减弱口门区回流尺度及引航道斜向流强度，以保证通航安全。 |
| 英文摘要: |
| Aiming at the engineering problems that there is large-scale back-flow whirlpool at the entrance of the upstream area in the hub ship lock on the curved reach and the oblique flow in the approach channel，we adopt the method of the whole normal hydraulic physical model tests，and research the influence of different dispatching mode of the discharge sluice on the navigation flow conditions of the upstream approach channel and entrance area of the convex-bank ship lock. The results show that the lock in the convex bank hub，discharge sluice opening the remote area at the entrance of the gateway of scheduling can effectively weaken the reflow scale and the intensity of the approach channel oblique flow to ensure navigation safety. |
