摘要(Abstract)：

采用理论研究和试验研究相结合的方法,对两层流体中内孤立波对不同水深竖直圆柱体水平作用力进行了分析。采用重力塌陷法进行内孤立波造波试验,通过PIV(Particle Image Velocimetry)技术获取内孤立波波剖面的时间序列,利用测力系统对竖直圆柱体在内孤立波作用下的受力进行测量。通过内孤立波波剖面试验分析,选取合适的内孤立波理论并对竖直圆柱体所受内孤立波作用力进行计算,将计算结果与试验结果进行汇总分析。结果表明:上层流体中圆柱体所受内孤立波最大水平作用力明显大于下层流体中各段圆柱体,且方向相反;随着内孤立波振幅的增大,各段圆柱体所受内孤立波最大水平作用力也相应地增大;密度跃层处圆柱体所受水平作用力具有相较于其他位置处更为复杂的变化趋势;选用合适的内孤立波理论进行计算能够较好的模拟竖直圆柱体的实际水平受力。
