摘要
通过物理模型和数学模型2种研究手段,对印度尼西亚PLTU2 JAWA BARAT 3×350 MW电厂码头工程波浪传播进行对比研究,分析港内外波高和波浪增水引起的水平面的变化。结果表明:对港内波高的分布情况数学模型模拟结果和物理模型试验结果基本吻合,从物理模型试验结果分析得出港内存在水平面的上升情况,MIKE21的BW波浪数学模型不能模拟波浪增水。分析了长周期波引起港内波浪共振的条件,港口的自振周期远远大于试验波要素的周期,故在此波浪作用下不会引起港内的共振。
Through physical and numerical model test,wave height distribution and the change of the wave height and water level in the harbor were studied, the options according to the test results were optimized. The results show that：the wave height distribution is basically consistent between numerical and physical model, the still water level in the harbor is rising through physical model test, but BW wave model of MIKE21 could not simulate the phenomenon. Harbor resonance due to the long-period wave action is analyzed. The period of the harbor vibration is longer than that of the wave condition, so the wave action cannot cause the harbor resonance.
