摘要
对不规则波浪作用下的非透空梳式防波堤结构进行了物理模型试验研究。试验分析了非透空梳式防波堤结构表面波浪压强的分布规律及工程危险水位;为寻求消减翼板波浪压强的工程解决方案,进而对3类改进的非透空梳式防波堤结构翼板上的波浪压强分布和堤前波浪反射系数进行对比分析,最终确定工字体挡板梳式结构为工程推荐结构。
The model experimental studies on the interactions between waves and non-open comb-type breakwater were conducted under irregular wave conditions.The distribution regularity of wave pressure on the original non-open comb-type breakwater and the most dangerous water level in the project were analyzed.Preliminary analysis indicates that the maximum wave pressure on the wing-plate exceeding the structural limit is the major factor that influences the structure safety.In order to seek the optimal structure that could reduce the wave pressure on the wing-plate,three different types of non-open comb-type breakwater structures were further investigated experimentally.Wave pressure distribution on the wing-plate and wave reflection coefficients were compared,and the non-open comb-type structure with ＂I＂ type baffle is confirmed as the optimal structure in the actual project.
