| 摘 要： | 通过对韩国某港北防波堤工程波浪整体物理模型试验研究,分别对比了普通直立式和开孔直立式2种沉箱结构的防波堤对港内泊稳条件的掩护效果。试验采用SSE、SE两个代表波向,采集并分析港内及防波堤周围水域的波高及分布。试验结果表明,采用相同入射波条件时,2种结构防波堤均可对港内形成一定程度的掩护。但由于工程海域波高较大,次生波的出现影响了泊稳条件。两方案相比,开孔沉箱结构的防波堤对拟建港区的掩护效果略好,综合比较最后推荐开孔沉箱结构的防波堤方案。

| Abstract: | Taking the north breakwater physical model tests of one South Korea Port as an example,the sheltering effects of berthing condition were compared between ordinary vertical caisson and perforated vertical caisson.The wave height of incident wave in SSE and SE directions was analyzed,and the measuring point was assigned in port and around the breakwater.Then the test data were compared and analyzed.The results show that,when using the same incident wave,the two breakwaters can form a shielded water area and keep out the wave.But due to the large wave height,the mooring conditions are influenced by the secondary waves.According to the comparison of the two schemes,the perforated vertical caisson is recommended. |
