摘　　要：本研究采用ABAQUS有限元软件,主要针对内河大水位差码头在最不利工况条件下受到船舶撞击时,码头结构的受力及破坏情况进行数学模拟,得出架空直立式码头的破坏模式。数学模拟结果表明,从码头结构被撞击开始到最终破坏,要经历由弹性变形-弹塑性变形-塑性变形的过程。IThe mathematic simulation was given on the stress and damage states of ship collision in inland rivers’ wharf with great water level difference under the most disadvantage poor working conditions by using the finite element software ABAQUS,and the destroy pattern of overhead tower wharf was obtained.The results of simulation show the damaged structure from start to final failure will undergo the processes of elastic deformation,elastic and plastic deformation and plastic deformation.
