桩基双挡板透空式防波堤水平波压力试验与计算

通过物理模型试验的方法,采用不规则波研究影响两侧挡板透空式防波堤水平波压力的主要因素及其规律性。在不越浪的前提下,分别对挡板不开孔、错位开孔和不错位开孔3种结构形式进行系统的物理模型试验,并分析总结无量纲因素即挡板相对入水深度和波坦对水平波压力的影响。在上述研究成果的基础上,提出了较为实用的透空式防波堤水平波压力计算公式,对透空式防波堤的研究和设计具有较高参考和借鉴价值。

Experimental study and calculation of horizontal wave pressure of piled baffle penetrated breakwater

Based on the physical modeling experiment,we study the main factors effecting the horizontal wave pressure of the penetrated breakwater with both-sides baffles and their regularities under the irregular wave.Without the overtopping wave,we carry out systematic physical model experiments respectively for the three kinds of structures,i.e.the structure without hole baffle,the one with staggered hole baffle and the one with unstaggered hole baffle,to analyze the influences of horizontal wave pressure effected by the dimensionless factors,which are the relative water depth of the baffles and the wave length-height ratio.On the basis of the research results above,more practical breakwater wave pressure formula are presented,which may serve as reference for the research and design of the penetrated breakwater.
