摘　　要：潜在自由水面以下的水平单板可作为一种新型的防波堤形式。为进一步揭示板式防波堤结构的消波原理,文章以水下平板式防波堤为例,利用边界单元法对平板周围的流场进行分析。研究发现:其主要消波原理为利用板上部水体产生的板上逆流与入射波浪发生强烈作用,在板的两端产生消浪区,使得流体区域内的水质点运动速度减小。Submerged horizontal plate can be considered as new concept breakwater. In order to reveal the wave elimination mechanism of this type breakwater, boundary element method is utilized to investigate the velocity field around plate carefully. The flow field analysis shows that the interaction between incident wave and reverse flow caused by submerged plate will lead to the formation of wave elimination area around both sides of the plate. The velocity magnitude of flow field is reduced and this is the main reason of wave elimination.
