摘　　要：为考察一种新型船用大抓力锚———DA-1锚的抓底性能,在分析国外资料的基础上,制作该锚模型,分别在粗砂底、细沙底和淤泥底上进行DA-1锚抓力大小的试验研究。试验结果表明,该锚在粗砂底和细沙底的抓力系数为7左右,在淤泥底上的抓力系数达15以上,初步显示DA-1锚在淤泥底上具有优异的抓底性能。In order to investigate the new type of high holding power anchor-DA-1 anchor for ship use, anchor models are made based on the analysis of technical materials overseas, and model tests to explore the holding capacity of DA-1 anchor are carried out on the seahed of coarse sand, fine sand and mud type respectively. The results show that the holding power of DA-1 anchor is about 7 on coarse sand bed or fine sand seafloor, and more than 15 on mud bed, indicating that this type of anchor has very high holding capacity at mud-bed anchorage.
