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Ct、反射系数Cr以及能量耗散系数Cl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.
A new type of free-surface semi-circular body is proposed, which is a marine structure with free water surface and semi-circular body. The model structure is tested with different water depths, different water depths, and regular and irregular waves in different wave heights and cycles The transmission coefficient Ct, the reflection coefficient Cr and the energy dissipation coefficient Cl of the structure are systematically summarized.It is found that the wave elimination performance of a free-form semi-circular open-sea structure increases with the relative water depth of the model and the relative width ; And the structure has smaller wave reflectivity and better energy dissipation effect, and is suitable for being popularized in the coastal infrastructure.
