进行了有裂流槽缓坡沙坝地形下,由反射壁反射的交叉叠加波浪形成的沿岸波高周期性变化所产生的裂流试验研究.试验中波浪场由斜向入射波浪在反射壁上的反射波和入射波交叉生成,交叉波浪是具有等波幅和等频率但入射角相反的两列规则波波列.通过对交叉叠加波浪下裂流槽附近范围的波浪场和流速场测量分析了有裂流槽缓坡沙坝地形情况下的裂流特性.通过不同周期引起的叠加波浪节腹点位置的变化,分析了不同周期对裂流槽中裂流的影响,表明在裂流槽地形下裂流受到周期和裂流槽的共同影响.
The experimental study on the crack propagation caused by the periodic variation of the coastal waves caused by the cross-superimposed wave reflected by the reflecting wall under the condition of the gentle slope of the cracked channel on the gentle slope of the dam is carried out. The wave field in the experiment is reflected by the reflection of the oblique incident wave on the reflecting wall The waves intersect with the incident waves, and the crossed waves are two regular waves with equal amplitude and equal frequency but opposite angles of incidence. By analyzing the wave field and velocity field in the vicinity of the trough under the cross-over wave, The effect of different periods on the rivulet flow in the rivulet is analyzed by the change of the position of the superposed wave node caused by different periods. It is shown that the rift flow in the rift channel Affected by the cycle and trough common impact.
