摘　　要：为研究船用钢板锚的啮土性能,以德尔泰锚为原型,设计一款缩尺比为1:5的锚模型,并在细沙中进行不同倾角下的锚模型拖曳试验。试验结果表明,锚倾角对锚抓力、啮土深度和拖曳距离等均有很大的影响。在倾角为35°的情况下,德尔泰锚在细沙中的抓力系数可达到13,初步显示德尔泰钢板锚具有良好的啮土性能。In order to investigate the holding capacity of marine steel anchors, the Flipper Delta anchor is used as the prototype to design an anchor model with 1:5 scale ratio for anchor dragging experiment in fine sand under different inclination angles. The experiment result shows that the inclination angle of anchor has large influence on the holding capacity, the gnaw depth in soil and the dragging distance. When the inclination angle is 35°, the holding power coefficient of Delta steel anchor can reach 13, which indicates that the Delta steel anchor has a good holding performance.
