摘　　要：利用ＭＭＧ模型建立锚泊船的船舶运动方程，采用蒙特卡罗方法．对走锚船的漂流运动进行了大量的计算机模拟，进而对模拟数据进行统计分析，得出了走锚船漂流方向的概率密度函数．The position of the probability density function of drifting direction after ship's anchor dragging is important for the safety assessment of ship anchoring. The dragging ship movement equation is presented by use of MMG model. The ship drifting after anchor dragging is simulated by computer according to Monte Carlo Method. The probability density functions are gained by analyzing the statistical simulated data.
