摘　　要：对一种适合于救助打捞、工程临时防护等应急防浪情况的新型应急浮式防波堤进行了研究。运用FLOW3D软件模拟了新型应急浮式防波堤在规则波作用下的运动过程,探讨了波陡H/L及相对吃水深度D/d对新型应急浮式防波堤透射系数以及锚链力的影响,并与波浪水槽内系列物理模型试验结果进行比较,验证了数学模型计算结果。研究结果表明,波周期是影响新型应急浮式防波堤透射系数及锚链力的重要因素,周期越大,透射系数及锚链力也越大,而相对吃水深度只在一定范围内对透射系数及锚链力有影响。该新型应急浮式防波堤的消浪效果良好,为其推广应用提供参考依据。A new type of floating breakwater was presented for the application to emergency aiding and tempo- rary protection. FLOW3D software was used to simulate the movement of the floating breakwater under regular wave. The influence of wave steepness H/L and relative draft D/d on the transmission coefficient and moor/ng forces was investigated. The numerical model was validated by comparing the results of flume experiment. Numerical resuits indicate that wave period has an important effect on the transmission coefficient and mooring force, and the transmission coefficient and mooring force are increased with wave period, while the relative draft are less determinant in the transmission coefficient and mooring force. The wave dissipation effect of this structure is fine, which provides a reference for its application.
