多层平板透流防波堤结构的消浪特性试验研究
Experimental study on wave-dissipation characteristics of multi-layer perforated plate breakwater
摘要
Abstract
Model tests were conducted in a two-dimensional wave tank to systematically investigate the effects of relative plate width,relative wave height,and relative plate spacing on the hydrodynamic performance of multi-layer horizontal plate breakwaters.The wave energy dissipation was analyzed as a function of both wave and structural parameters.The results indicate that the wave transmission coefficient varies with relative plate width,with an optimal range of B/L=0.4-0.6.Superior wave energy dissipation efficiency is demonstrated,particularly under high-wave-height conditions.Although the influence of relative plate spacing on wave dissipation is found to be relatively small,its effect becomes more pronounced as the relative wave height increases.It is observed that multi-layer horizontal plates transform two-dimensional regular waves into higher-order three-dimensional high-frequency waves,thereby accelerating energy dissipation.Furthermore,the top plate is found to enhance the structure's capacity to withstand and dissipate energy under high-wave conditions.Overall,the multi-layer horizontal plate breakwater exhibits robust wave attenuation capabilities under the experimental conditions,suggesting significant potential for enhancing coastal protection structures in practical engineering applications.关键词
