摘　　要：针对船舶射流作用下码头护底损坏的工程问题,分析比较了PIANC推荐的荷兰方法和德国方法,以及TheRockManual推荐的算法。得出结论:荷兰方法对块石护底的设计较为适用,德国方法在均质土壤或级配土壤冲刷问题上有较好的适用性,重力式码头可适当增加护底冲刷流速计算值。基于研究成果,以非洲某港口项目为例,采用荷兰方法对重力式码头护底进行了设计。In view of the engineering problem caused by the damage of the gravity quay protection unit under the action of the ship jet,the Dutch method and the German method recommended by PIANC,as well as the algorithm recommended by The Rock Manual,are analyzed and compared.It is concluded that the Dutch method is more suitable for the design of block stone bottom protection,and the German method has good applicability in the problem of homogeneous soil or graded soil erosion;gravity wharves can appropriately increase the calculated value of the bottom protection erosion velocity.Based on the research results,taking a port project in Africa as an example,the Dutch method is used to design the gravity quay protection unit.
