摘　　要：针对围油栏水动力特性的问题,进行了模型比尺为1:1的规则波、水流与围油栏相互作用的大比尺水槽物理模型试验。利用拉力传感器和Polhemus电磁式位置跟踪系统,对围油栏的受力和不同浮子的运动响应进行了测量,研究了不同环境因素(周期、波高、流速)对围油栏水动力特性的影响。试验结果表明,在波流组合的情况下,围油栏的受力情况对水流流速最为敏感,波高其次,波浪周期对其影响最小。围油栏不同位置的浮子水平运动特征不同,但各个浮子的运动响应幅值均对波高较为敏感,基本同波高成线性关系。同时,水流抑制了各个浮子的水平运动,但使其升沉运动更为剧烈。Aiming at the hydrodynamic characteristics of the boom, a large-scale physical model test with a model scale of 1:1 was conducted. The wave force of the oil boom and the motion responses of different floaters on the oil boom were measured by the underwater tension sensors and Polhemus electromagnetic position tracking system . The influence of different environmental factors (wave period, wave height, current velocity) on the force and motion response were analyzed. The experimental results show that the wave force of the oil column is more sensitive to the current velocity than the wave height and the wave period in the case of wave-current combination. The motion response amplitudes of various floats on the oil boom is relatively sensitive to the wave height, which is basically linear with the wave height. The water flow inhibits the horizontal movement and promotes the heave motion of various floats.
