摘　　要：反射波的抑制是提升波浪水槽试验性能的关键。通过物理模型试验,在不同波长、波高、水深条件下,探究多层变孔径倾斜孔板消波装置对波浪的消波性能影响,并通过耦合添加塑料网状结构、水平板以及三角消波网等装置模块优化其性能。试验结果表明:多层变孔径倾斜孔板消波装置倾斜角度越小,消波装置的消波效果越好。多结构复合体能显著提高多孔倾斜消波装置的消波性能,尤其是三角消波网的引入能够在装置前方有效地使波浪发生聚集破碎。从试验结果可以看出,其明显改善了装置的消波效果,尤其是对长周期波。试验中优化的最终装置形态将反射系数控制在较低的水平。The suppression of reflected waves is the key to improve the experimental performance of wave flumes.In this paper,through physical model experiments,the wave damping performance of multi-layer variable aperture inclined orifice damping device on waves was explored under varying conditions of wavelength,wave height and water depth.The performance was optimized by incorporating additional modules such as a plastic mesh structure,horizontal plate,and triangular wave damping net.The test results show that the smaller the tilt angle of the multi-layer variable aperture inclined orifice damping device,the better the wave dissipation effect of the wave damping device.The multi-structure complex can significantly improve the wave dissipation performance of the porous inclined wave damping device,especially the inclusion of a triangular wave damping net.From the experimental results,it significantly improves the wave dissipation effect of the device,especially for long-period waves.The optimized device morphology achieved in this paper effectively lowers the reflection coefficient.
