中文摘要:
      本文分析两种计算船舶抛锚贯入深度的方法,分析不同方法的特点及对于不同土参数的敏感性。以海洋20m水深和25m水深为例,分别使用两种方法计算不同海底土参数状况下抛锚的贯入深度。基于正交试验原理分别分析了能量法与微分方程法计算抛锚贯入深度时的参数敏感性。本文结果表明,基于能量方法计算得到的贯入深度大于微分法计算得到的贯入深度,且能量法对于内摩擦角最敏感,而微分法对于土的有效重度最敏感。
英文摘要:
      In this paper, two methods for calculating the penetration depth of ship anchoring are analyzed, and the characteristics of different methods and their sensitivity to different soil parameters are analyzed. Taking the depth of 20 m and 25 m as examples, two methods are used to calculate the penetration depth of anchor under different seabed soil parameters. Based on the principle of orthogonal test, the sensitivity of energy method and differential equation method to calculate the penetration depth of anchor is analyzed. The results show that the penetration depth calculated by the energy method is greater than that calculated by the differential method, and the energy method is the most sensitive to the internal friction angle, while the differential method is the most sensitive to the effective weight of soil.
