某一级渔港防波堤及口门布置方案

Layout plan of breakwater and entrance of a first-grade fishing port

防波堤尺寸及口门布置方向对港内各处波高分布、港池泊稳效果及港池淤积情况都有较大的影响,防波堤及口门的合理布置是渔港建设成败的关键因素。基于针对工程实例的波浪及潮流泥沙数学模型试验研究成果,从港内掩护效果、操船安全性、港内泊稳情况等角度对海南某一级渔港防波堤总平面布置、尤其是口门布置方案进行比对分析与优化设计,为渔港防波堤工程设计及施工提供指导。

The dimensions of the breakwater and the direction of the entrance have great influences on wave height distribution,berthing stability and sediment in the harbor basin,and the reasonable arrangement of the breakwater and the entrance is the key factor for the construction of the fishing port.Based on the results of mathematical models of wave,tidal current and sediment of the engineering case,we carry out a comparative analysis and optimization design of the general layout,particularly the entrance layout of a first-grade fishing port in Hainan from angles including the shielding effect,safety of ship operation,and berthing stability,etc.to provide a guidance for the design and construction of the fishing port breakwater.
