港口长周期波问题的应对措施

Countermeasures against problems of long-period wave in ports

针对长周期波带来的港口作业问题,研究国外港口缓解长周期波成功案例,凝练出抑制长周期波波源、优化平面布局、构建消波结构物、改进系泊配置、开发预报系统等5个方面的应对措施。研究表明,抛石斜坡堤(宽度不小于30 m)、真空系泊系统(MoorMaster^(TM)、Auto Moor等)和液压系泊系统(ShoreTension■)为行之有效且低成本的对策,可供类似工程参考。

Regarding the problems of port operations caused by long-period waves,we study the successful cases of long-period wave mitigation in foreign ports,and propose five countermeasures including restraining long-period wave sources,optimizing plane layout,constructing wave absorbing structures,improving mooring configuration and developing prediction system.The study shows that rubble mound breakwater(width not less than 30 m)and vacuum mooring system(MoorMaster^(TM),Auto Moor,et al.)and hydraulic mooring system(ShoreTension)are effective and low-cost countermeasures,which may serve as reference for similar projects.
