概透空管桩潜堤消浪效果物理模型试验研究

Physical Model Experimental Research on Wave Dissipation Effect of Submerged Embankment on Permeable Pipe Piles

针对已建桩基挡板透空式防波堤堤后水域波高较大,会影响码头前沿船舶的作业,则在透空堤前布置板桩潜堤和透空管桩潜堤,并通过物理模型试验进行了2种潜堤的消浪效果研究,重点研究潜堤距桩基挡板透空式防波堤前半波长内不同位置时,潜堤堤前水深、堤身高度、透空管桩间距变化对透空式防波堤堤后水域透浪系数的影响。

The submerged embankments supported on sheet piles and permeable pipe piles are arranged in front of the permeable breakwater with pile foundation baffle to protect the ships’ operation from larger wave height behind the finished permeable breakwater. Two kinds of submerged embankments are compared and studied from the aspect of wave dissipation effect based on physical model experiment, which focuses on the effect of water depth in front of submerged embankment, height of submerged embankment and spacing change of permeable pipe piles on wave transmission coefficient behind permeable breakwater under the condition that the submerged embankment is about half wave length far from the permeable breakwater with pile foundation baffle.
