摘要
为保障海水养殖网箱在风浪中的安全及良好的海水交换功能 ,采用浮式防波堤掩护是切实可行的工程措施。该防波堤具有轻便、机动、经济等优点。模型试验结果表明 ,浮式防波堤 (箱式浮堤和筏式浮堤 )对于深水短波具有良好的消波效果 ,当水深与波长比 >0 .5 ,不论何种浮堤方案均能得到较好的消波效果 ;当水深波长比 <0 .2 ,不论何种浮堤方案消波效果均较差 ;相比之下 。
Two floating breakwater models (box breakwater and raft breakwater) were designed at the conditions that the high tide water depth was 15 m and tide height 3.5 m at force 8 wind. In the test, some additional conditions were added that the tide height had another 3 levels: 1.5, 2.5 and 3.5 m, and the wave steep at 10, 15 and 20, respectively. The results show that the models have good effects in deep water with short wave; when d/L(ratio of water depth and wave length)>0.5, both models can get good effect; when d/L<0.2, both get bad effect. It comes to the conclusion that the raft breakwater is more feasible, portable, economical and secure in protecting the seawater culture cages in wave and in normal seawater exchange.
