基于FLOW-3D的新型桩基透空堤消浪性能研究

针对新型附带消浪板桩基透空堤消浪性能,对波浪作用下该新型透空堤的反射系数、透射系数以及波能分布进行研究。采用FLOW-3D数值模拟方法,得出消浪板的开孔率、相对入水深度以及倾斜角度变化时透空堤反射系数、透射系数以及波能分布。结果显示:1)该新型附带消浪板桩基透空堤具有较好的消浪性能,开孔率越小,其反射系数越大、透射系数越小;2)消浪板开孔率为10%,相对入水深度为0.85,倾斜角度为-15°的设计方案效果最佳,该新型透空堤透射波能占比仅约为17%。

Wave dissipation performance of new type of pile foundation permeable breakwater based on FLOW-3D

In terms of the wave dissipation performance of a new type of pile foundation permeable breakwater with a wave dissipation plate,this paper studies the reflection coefficient,transmission coefficient and wave energy distribution of the new type of permeable breakwater under wave action.Using FLOW-3D numerical simulation method,the reflection coefficient,transmission coefficient and wave energy distribution of the permeable breakwater are obtained when the opening ratio,relative water depth and inclination angle of the wave dissipation plate change.The results show that:1)The new type of pile foundation permeable breakwater with a wave dissipation plate has good wave dissipation performance.The smaller the opening ratio is,the greater the reflection coefficient is and the smaller transmission coefficient is.2)The design scheme of 10%opening rate,0.85 relative water depth and-15°inclination angle has the best effect,and the wave energy transmission coefficient of the new type of permeable breakwater is only about 17%.
