船舶进出闸室对系缆力的影响

Analysis of mooring force influence given by larger ships passing through a shiplock

  • 摘要: 船舶进、出闸室时,船行波在闸室内引起较大水面波动,造成闸室内系缆船舶的系缆力增大,影响闸室内的船舶停泊安全;大型船舶进、出闸室时,产生的船形波作用更强,对系缆船舶的系缆力影响更大。通过1:36.3三峡船闸的物理模型和相同比尺5 000 t级典型大型船舶模型,采用系列物理模型试验,对船舶进出船闸时闸室内系缆船舶的系缆力进行了研究。研究结果表明,闸室内有系缆船舶时,船舶进、出闸的航行速度对系缆船舶的系缆力影响很大,进、出闸速度越快,其系缆力也越大。三峡船闸中,当水深5.5 m,闸室内有系缆船舶,大型船舶偏航进、出闸室时,为保证船舶停泊安全,航行船舶的进、出闸速度宜小于0.5 m/s。

     

    Abstract: The ship wave caused by ships exiting from or entering the shiplock would enlarge the mooring force of berthed ships in the shiplock and be harmful for the mooring safety. Large-size ships entering or exiting from the shiplock may cause greater ship-induced waves and give remarkable influences upon the berthed ships. So to study the mooring force of the berthed ships caused by moving ships is necessary and important. The mooring force of the large-size ships in the Three Gorges shiplock is studied by conducting a physical model test of the shiplock, of which the scale is 1:36.3. A 5 000 t class ship model is used for the tests. The analysis results show that the ship speed gives a great influence on the mooring force. And if the water depth in the shiplock is 5.5 m, the slip speed exceeds 0.5 m/s, and the mooring force on typical berthed ship may exceed the standard value specified by the codes. When the water depth in the Three Gorges shiplock is 5.5 m, and the ship is berthed in the shiplock, the speed of other ships entering or exiting from the shiplock should be lower than 0.5 m/s for the safety.
