| 摘 要： | 通过对4种不同结构形式的浮式防波堤进行实验研究,分析了浮式防波堤在规则波作用下防波堤透射系数与模型顶板相对入水深度q/d、相对板间距s/d、相对板长B/L以及顶板开孔的关系.研究结果表明,相对板长是影响防波堤消浪性能的最重要因素.在加大锚链拉力的同时,增加防波堤长度是提高防波堤消浪性能的有效方法.

| Abstract: | Four kinds of different structure forms of floating breakwaters were put forward.The transmission coefficient of floating breakwater was defined,and its relative depth of submergence and relative plate-spacingwere analyzed,with or without holes on model roof and the relative plates-length for the floating breakwater under regular wave.The results show that its bodylength is the most important factor during affecting the wave dissipation and the transmission coefficient reduces with its increase. |
