规则波作用下组合式潜堤消浪性能试验研究

通过物理模型试验对梯形和矩形组合式潜堤的消浪性能进行研究,比较组合式潜堤与单排布置潜堤的消浪性能,分析堤顶水深、波高、间距及组合堤排数等因素对潜堤透射系数Kt的影响。试验结果表明:组合式潜堤的透射系数随着堤顶水深的增加而增加,随着波高的增大而减小;组合式潜堤排数越多消浪效果越好,可根据实际工程需要恰当地选择潜堤的布置排数。

Experimental study on performance of combined submerged breakwaters in regular wave

A physical model test method is carried out to study the wave dissipation performance of the trapezoidal and rectangular combined submerged breakwaters.The attenuation effect of the single submerged breakwater and the combined ones is compared,and the effect of some factors such as the water depth on the breakwater,the wave height,the spacing and the number of submerged breakwater on the transmission coefficient Kt of submerged breakwaters are analyzed.The experimental results show that the transmission coefficient of the combination of submerged breakwaters increases with the water depth on the breakwater,and decreases with the increase of wave height.When the distance between the combined submerged breakwaters is close to half wave length,the wave dissipation effect is comparatively obvious.The more breakwaters submerged in the water,the better the attenuation effect achieved,and the number can be chosen according to the actual project.
