【摘要】：由于波浪作用下水质点周期性振荡运动的特性,对其运动轨迹的直接观测一直是比较困难的问题。然而对波浪作用下水质点运动轨迹的直接观测不仅有助于波浪理论的进一步发展,也有助于人们对波浪运动特性的客观理解。为此提出了一种成本极低的新型水质点示踪装置。该装置可直接观测波浪作用下的水质点运动,且结构简单、操作方便、环保安全,不影响水槽展开其他试验。结合系列水槽试验,详细讨论了该装置的工作原理和操作方法。试验结果充分表明,该装置与方法可以完成对不同波浪要素下水槽中任一水质点的示踪,试验数据符合波浪理论规律,证明了该装置的实用性和可靠性。
[Abstract]:Due to the characteristics of periodic oscillatory motion of water points under the action of waves, it is always difficult to observe the motion trajectory directly. However, the direct observation of the motion trajectories of water points under the action of waves is not only helpful to the further development of wave theory, but also to the objective understanding of the characteristics of wave motion. For this reason, a new type of water quality point tracer with very low cost is proposed. The device can directly observe the movement of water quality points under the action of waves, and has the advantages of simple structure, convenient operation, environmental protection and safety, and does not affect other tests in the flume. Combined with a series of flume tests, the working principle and operation method of the device are discussed in detail. The experimental results show that the device and method can trace any water quality point in the flume under different wave elements, and the experimental data accord with the wave theory law, which proves the practicability and reliability of the device.
