基于船舶操纵仿真试验的弯曲河段复线船闸引航道方案论证和优化

Demonstration and optimization of approach channel scheme for double track ship locks in curved river sections based on ship maneuvering simulation tests

临淮岗复线船闸上游折线形引航道设置警示分隔墩后,下游引航道回流严重、横向流速局部超标。针对安全航行的问题,开展船舶操纵仿真试验。结果表明:上游引航道宽度、转弯半径可满足船舶安全进出闸的需要;曲进直出的折线形引航道布置方案,上行出闸船舶为航行安全的控制工况,在停泊段双排停靠1000吨级船舶时,安全富余较小;两闸之间的警示分隔墩平面布置长度过长对出闸船舶的航行存在不利影响,其纵向布置范围不应与停泊段重叠;下游引航道不超标部分宽度可满足船舶安全航行需要。

After the installation of warning separation piers in the upstream zigzag approach channel of the Linhuaigang double track ship locks,there is the serious reflux and local exceeding of lateral flow velocity in the downstream approach channel.In response to the safety navigation issues,we conduct ship maneuvering simulation tests.The resuts show that the width and turning radius of the upstream approach channel can meet the needs of safe entry and exit of ships at the ship lock.The layout scheme of a curved and straight out zigzag approach channel is a control condition for navigation safety,and the safety margin is relatively small when two rows of 1000-ton ships are docked in the berthing section.The length of the warning separation pier between the two gates is too long,which has a negative impact on the navigation of ships exiting the gate.The longitudinal arrangement range should not overlap with the mooring section.The width of the downstream pilot channel that does not exceed the standard can meet the safety navigation needs of ships.
