摘　　要：本文以某港30万t级原油泊位为例,研究外海开敞墩式码头的结构优化方案,并通过物理模型试验验证优化后的结构方案对码头面上水的影响效果。试验结果表明,采用透空结构(如双柱块体上部结构、开孔沉箱)能改善高水位情况下码头面上水情况,而透空结构所处的位置决定了其对码头面上水高度影响的大小,透空结构位于波能集中区域时对上水高度的影响最为显著。后续进行类似工程结构设计时,可加以借鉴。Based on a berth for accommodating oil tankers up to 300,000 DWT,the optimum structure plan for open-sea pier wharf is studied,and the influence of the optimized plan on the wave-overtopping of wharf surface is verified by physical model experiment.The experimental results show that the application of permeable structure(such as double-column block and perforated caisson)can reduce wave overtopping under the condition of high water level,and the position of permeable structure influences the wave overtopping level directly.In addition,the permeable structure located in wave-energy concentration area impacts the wave overtopping level significantly,which will provide a reference for subsequent similar projects.
