摘要： 基于Flow-3D软件,建立抗拖网海床基沙土基床冲刷的三维数学模型,控制水流流速和泥沙粒径,对不同条件下抗拖网海床基周围沙土基床的冲刷进行数值模拟,并分析了抗拖网海床基最大冲刷深度随这两种因素改变的趋势。结果表明,抗拖网海床基沙土基床冲刷坑深度随海流流速增大而增加,在设定其他条件不改变的情况下,冲刷坑的加深速度随着流速增大会逐渐减缓,最终达到冲淤平衡。同时,由于海底环境复杂多变,导致模型与实际情况有一定的差异,还需在后续的研究中进一步进行优化。

Abstract: Three-dimensional mathematical model of scour around Trawl Resistant Seabed Basement on sand bed was established using Flow-3D. By changing the flow velocity and sediment particle size, the scour on sand bed under different conditions was simulated, and the changes in the trend of maximum scour depth around Trawl Resistant Seabed Basement with the two factors was analyzed. The results show that the scour depth around Trawl Resistant Seabed Basement is increased with current velocity increases, under the other setting conditions unchanged, the scour pit deepened velocity with increasing flow velocity is gradually slowed down, and ultimately achieved sedimentation balance. At the same time, due to the complex and changeable seabed environment, the model and the actual situation are different, and therefore further research should be continued.

Key words: Trawl Resistant Seabed Basement, sediment scour, numerical simulation
