| 摘 要： | 在导出作用于管式透空直立式防波堤波浪反射系数之后，本文对由于透空存在而使波浪透入港内的机制进行了分析，考察了影响透射波高的各种因素，确定了堤厚的作用，并依据物理表现寻求具有待定系数的函数表达式，由水动力模型试验数据拟合了函数表达式中的待定系数。本文所得表达式不仅反映了波动的物理机制，而且在数值上达到了令人满意的结果。

| Abstract: | Based on the derivation of reflection coefficient of the perforated-pipe breakwater, the mechanism of wave perforated into basin is analyzed and the factors affecting perforated wave heights are examined. It is shown that the width of the wall, i.e. the length of the hollow pipes is significant. A function with unknown parameters is derived based on dimensional analysis, and the unknown parameters are found by curve fitting from the data of hydraulical modelling. All these show that the analysis of the physical phenomena and the results of formula fitting from data numerical analysis are satisfactory. |
