摘　　要：固壁附近的水平圆柱体在波浪、波流作用下的受力情况与其周围的流场状态密切相关。为探讨圆柱受力形成的机理，应当对流场的涡结构有充分的认识，受力过程与流态演化过程的同步分析尤为重要。本文通过实验研究并对比数值分析的结果，对波浪、波流场中圆柱体受力与流场状态的关系做一初步讨论。The hydrodynamic characteristic of a circular cylinder near a plane boundary is closely related with the flow field about. In order to investigate the justification for causing the wave-current force on cylinder, the vortex structure of the flow field should be well known, and it is important to analyse the evolution of flow field and process of wave-current action on cylinder synchronously. A preliminary discussion to the relation between wave-current force and the state of flow field of the cylinder is given in this paper the results come from flow visuialization experiment and also compared with numerical calculation result.
