| 摘 要： | 为研究闸门开启方式对枢纽下游引航道口门区水流特征及通航水流条件的影响,以北江白石窑枢纽泄水闸为例,针对不同闸门开启方式对下游引航道口门区通航水流条件的影响开展三维数值模拟研究。结果表明:在较小流量情况下,闸门开启方式对下游引航道口门区通航水流条件影响较小;当流量较大时,闸门开启方式对下游引航道口门区通航水流条件影响较大。对于白石窑枢纽泄水闸,单开左岸泄水闸,或集中开启左岸泄水闸并间隔开启右岸泄水闸,下游引航道口门一线船闸航道右侧将不能满足通航水流条件要求。为保证船舶航行安全,建议该工程在下泄洪水时尽可能开启右岸泄水闸,或均匀开启全部泄水闸。

| Abstract: | The sluice gates of the Baishiyao Hydro-Junction in the Beijiang River were selected to study the influence of the sluice gate opening mode on flow features and navigation flow conditions in the entrance area of an approaching channel downstream of the hydro-junction. Three-dimensional(3D)numerical simulation was conducted on the influence of different sluice gate opening modes on the navigation flow conditions in the entrance area of the downstream approaching channel. The results show that the influence of sluice gate opening modes on the navigation conditions is small when the flow is low, and the influence of sluice gate opening modes on the navigation conditions is large when the flow is high. For the sluice gates of the Baishiyao Hydro-Junction, a single opening of the left sluice gate or intensive opening of the left sluice gate with opening at intervals of the right sluice gate will prevent the navigation flow conditions of the right side of the first-line ship lock from meeting the requirements in the entrance area of the downstream approaching channel. To ensure the safety of navigation, it is suggested that the right sluice gate of the Baishiyao Hydro-Junction be opened or else all the sluice gates be opened during flood drainage. |
