摘　　要：在港口工程、水利工程及海洋工程研究领域,常借助水槽或水池等设施进行物理模型实验研究。主动吸收式造波技术可以有效解决实验室造波过程中的二次反射问题,在水池中生成高质量的模拟波浪场,按照比尺充分还原实际海况。文章从反馈信号类型的角度出发,回顾和论述了基于板上波高信号反馈、板前波高信号反馈以及力信号的三种主动吸收式造波技术的发展与应用,总结对比各种技术在传感器性能、系统稳定性和适用范围等方面的优势与不足,并分析了主动吸收式造波技术的核心与难点,最后结合国内外发展现状,分析发展趋势并提出发展建议。Physical model experiments were often carried out in flumes or basins in the field of harbor engineering,hydraulic engineering and ocean engineering.The problem of re-reflected waves was solved by active absorption wave-making technology and high-quality simulated wave field was generated in wave basins.The actual sea state was fully simulated according to the scale similarity.From the perspective of different feedback signals,the active-absorbing wavemaker technology based on the wave height on the paddles,the wave height in front of paddles and the force signal were reviewed respectively.The advantages and disadvantages of various technologies were compared in three aspects of sensor capability,system stability and application scope,and thekernel and key problems of technologies were analyzed.Finally,the development trend and suggestions were put forward according to the current development at home and abroad.
