摘　　要：对透空管组成的防波堤波浪反射、传递系数和堤上波浪力等水动力学特征进行研究。在对透空管非线性消耗波能机理分析基础上,采用-种简单的线性化方法,导出一组所有参数都是事先知道的、完全封闭的公式。波浪反射系数和堤上波压力与波浪力计算结果与试验吻合较好。The reflection and transmission coefficients as well as wave pressure and wave force on the perforated--pipe breakwater are studied. Based on analyzing the flow re- sistance and linearizing the acceleration term, the analytical formulas of reflected and transmitted wave heights and wave loads are obtained. In the formulas all of the param- eter can be either obtained from the textbook and manual, or calculated by structural and hydrologic parameters. The theoretical predictions by the present method are com- pared with the tested data. It is found that the results from this theory are in agreement with the experimental data in literatures.
