为了寻找一种简单、经济、有效的深水养殖浮式防波堤结构型式，对单箱、双箱和板网三种结构型式进行了研究。在实验室波流水槽中进行了二维物理模型试验，测定了三种防波堤在规则波和无流作用下的透波系数。在初步比较波浪透射系数的基础上，提出了采用板网浮式防波堤配合网箱使用的方案，并进行了详细的试验研究，考察了板宽、网排数、板刚度和流速等因素对波浪透射系数的影响。试验结果表明，板网浮式防波堤结构简单，造价低廉，能有效地保护鱼类和网箱，可用于深水区的养殖工程。
To find a simple, inexpensive, and effective type of floating breakwater for deep-sea aquaculture, we studied three types of structures: the single box, the double box, and the board net. We conducted two-dimensional physical model tests in a wave-current flume in the laboratory to measure the wave transmission coefficients of the three types of breakwaters under regular waves with or without currents. Based on the initial comparison of the wave transmission coefficients, we proposed the use of the board-net floating breakwater for use with fish cages; we then conducted detailed experiments to examine how wave transmission coefficients are affected by several factors, including the width of the board, the row number of the net, the rigidity of the board, and the current velocity. The experimental results show that the board-net floating breakwater, which is a simple and inexpensive type of structure, can effectively protect fish and fish cages and may be adopted for aquaculture engineering in deep-water regions.
