摘　　要：以3万吨级船舶以较快速度平行靠泊高桩码头为例,对不同方法计算出的最大船舶撞击力进行比较分析。应用有限元方法对船舶撞击码头的过程进行了数值模拟,根据码头结构产生的最大拉、压应力和混凝土强度破坏准则判断码头的损伤情况,由此确定码头升级改造的可行性。Taking the high-pile wharf subjected to the action of 30 000 DWT ship impact at a fast speed for example,we analyze the ship impact force calculated by different methods,simulate the process between a ship and a high-pile wharf by the finite element,according to the first principal stress,the third principal stress and failure criterion for concrete to judge the damages of the wharf,and determine the feasibility of the wharf’s upgrading.
