| 中文摘要: |
| 提出了自由水面式半圆体开孔这一海洋结构物的新型式,并对该型式结构物进行了不同水深、不同模型浸水深度,以及不同波高和周期下系统的规则波及不规则波的模型实验研究．对结构物的透射系数 C t、反射系数 C r以及能量耗散系数 C l进行了系统总结．通过研究发现自由水面式半圆体开孔海洋结构物的消波性能随着模型相对水深以及相对板宽的增加而增强;并且该结构具有较小的波浪反射率以及较好的能量耗散效果,适合在海岸基础设施中推广建造． |
| 英文摘要: |
| A new kind of perforated free surface semicircular naval structure is presented. The hydrodynamic characteristics of naval structure are investigated in regular and irregular wave conditions under the different water depths, submergence depths, wave heights and wave periods. The performance of the naval structure was evaluated in the form of transmission coefficient ( C t), reflection coefficient ( C r) and energy dissipation coefficient ( C l). It is found that the wave attenuation ability of the naval structure model improves with the increase of submerged depth and relative plate width. The naval structure performs better as an energy dissipater than as a wave reflector, and is suitable for offshore infrastructure construction. |
