摘　　要：数值模拟港口集装箱群在强风作用下的倾覆干扰效应,分析集装箱群的倾覆临界风速干扰因子随集装箱堆放的排数、间距和层数变化的规律,并比较两堆和三堆集装箱的干扰因子.结果表明,集装箱堆局部集装箱的倾覆临界风速要比集装箱堆整体倾覆临界风速要小;随着层高的增加,各堆集装箱群的倾覆临界风速均相应的减小;随着排数的增加,各堆集装箱群的倾覆临界风速均相应的增大;随着间距的增加,各堆集装箱群的倾覆临界风速逐渐接近于单堆集装箱群.The overturning interference effect on port container groups under strong wind is simulated numerically. The variation of the overturning critical wind velocity interference factor of container groups to the number of rows, spacing and layers is analyzed. The comparison of interference factor between 2-pile container group and 3-pile is carried out. The results indicate that the overturning critical wind velocity of local container in container pile is lower than the velocity of container pile as a whole. The overturning critical wind velocity of each container group decreases with the increase of the layers, but increases with the increase o（ the row number, closes to the single container group with the increase of spacing.
