中文摘要：

研究一种可应用于维护网箱养殖区域安全的浮式防波堤——矩形箱式浮防波堤。通过实验室物理模型试验研究了规则波作用下几种不同相对拖地系数的矩形箱式浮防波堤的透射系数、运动响应和锚链力。探讨了相对宽度和相对拖地系数对透射系数和运动响应及锚链力的影响。试验结果表明,相对拖地系数为0的模型透射系数在0.38-0.87,消波效果理想,但锚链力较其他相对拖地系数不为0的模型大。试验研究为深水网箱养殖区箱式浮防波堤的设计和安装提供参考和依据。

英文摘要：

In this paper, a kind of box-type floating breakwater used for protecting the area of offshore cage aquaculture is presented. The physical model experiments are conducted to study the hydrodynamic characteristic. The experimental results show that the ratio of wave attenuation of box-type floating breakwater is up to 65 %. So the box-type floating breakwater has good ability of dissipating wave. It can be applicable to ocean aquaculture engineering. The research results can provide basis for designing and installing floating breakwater in offshore cage aquaculture area.
