摘　　要：介绍了实验室的造波机系统和造波特性及其在模型试验中的应用 ,并讨论了实验室内模拟海浪的检验标准及其方法 .水槽模拟海浪的检验结果表明 ,本造波机系统能够准确地模拟波浪 ,规则波的波高横向误差小于 2 % ,波高重复误差小于 1 .2 8% ,周期重复误差小于 0 .2 % ;不规则波的平均波高误差小于 4.87% ,平均周期误差小于 4.5 9% ,波高重复性误差小于 1 .87% ,波高横向误差小于 3.71 % .波谱拟合较好 ,均满足“波浪模型试验规程”This paper discusses the wave_making system and its characteristics as well as the application of this system to model tests in the laboratory. The standards of inspection and the methods of simulating wave are also presented. The test results in the flume indicate that the system can simulate waves correctly. In the regular wave experiment, the transverse error of wave height is less than 2% , the repeated error of the wave height is less than 1.28% and the period repeated error is less than 0.2%. In the non_regular wave experiment, the average wave height error is less than 4.87%, the average pariod error is less than 4.59%, while the repeated error of the wave height is less than 1.87% and the transverse error of wave height is less than 3 71%. The wave spectrum simulated are perfect and can meet the requirement of wave model tests.
