八堡船闸在钱塘江潮影响下运行特性的原型观测

Prototype observation of operating characteristics of Bapu ship lockunder influence of Qiantang River tide

八堡船闸是京杭运河沟通钱塘江第二通道的关键性节点工程,船闸运行时受到钱塘江潮涌影响。为了确保八堡船闸长期稳定高效运行,针对钱塘江不同节令下的不同潮涌高度潮水进行船闸整体运行调试和实船试验,测量八堡船闸在潮汛期间的运行、通航状态,保障船闸安全。结果表明,在钱塘江小潮汛期间,潮水对八堡船闸影响有限,八堡船闸可正常运行;在大潮期间,引航道条件恶劣,八堡船闸应放下挡潮门、停止运行,待退潮后再进行通航。

Bapu ship lock is a key node project of the second channel connecting Beijing-Hangzhou Canal and Qiantang River,and the operation of the locks is affected by the tidal surges of Qiantang River.To ensure the long-term stable and efficient operation of Bapu ship lock,the overall operation of the locks debugging and the real ship test are carried out for the tidal surges of different tide heights in different seasons of Qiantang River,and the operation and navigation status of Bapu ship lock during tidal flooding is measured to ensure the safety of the lock.The results show that during the small tidal flood of Qiantang River,the tidal water has limited influence on Bapu ship lock,and the Bapu ship lock can operate normally.During the big tidal flood,the conditions of the approach channel are poor,and the Bapu ship lock should put down the tidal gate to stop the operation,and then carry on the navigation after the tide goes out.
