锚地选址时的底质影响因素分析

Influential factors of bottom material in anchor site selection

针对锚地选址时的底质影响问题,对比分析国内外锚地底质研究成果,根据锚抓力试验结果分析不同底质条件对应不同船锚类型的锚抓力系数,论述船锚类型和锚地底质对于锚抓力的影响,最终将锚地底质条件按照不同锚型的锚抓力系数进行分类;分析研究底质对于卧底锚链摩擦力的影响并给出典型大型船舶在不同底质上的卧底锚链摩擦力,说明卧底锚链长度对船舶锚泊的影响。得出如下结论:锚地底质的适宜性跟使用锚地的船舶类型、等级、锚型等因素有关,应对使用锚地的船型进行分析论证,必要时应开展锚泊试验论证。

For the influence of the bottom material on the anchorage site selection, we compare and analyze research results on the bottom material of the anchorage at home and abroad, analyze the anchor holding power coefficient of different anchor types corresponding to different bottom material conditions through according to anchor holding power test results, discuss the influence of the anchor type and the bottom material on the anchor holding power, and classify the anchor bottom material conditions according to the anchor holding power coefficient of different anchor types. We also analyze the influence of the bottom material on the friction of the laid chain and give the friction of the laid chain of the typical large ship on different bottom materials, and explain the influence of the length of the laid chain on the anchoring of the ship. The conclusion is drawn that the suitability of the bottom material of the anchorage is related to the type, grade, and anchor type of the ship using the anchorage. The ship type using the anchorage should be analyzed and demonstrated in detail, and the anchoring test should be carried out if necessary.
