摘　　要：为研究新型架空直立式码头结构的抗震性能,利用ABAQUS有限元软件建立新型架空直立式码头结构和传统码头结构的有限元模型。首先对两种码头进行模态分析研究自振特性,然后考虑桩土接触非线性的影响,对两种码头结构型式进行动力响应时程分析。提取两种码头面板的水平位移,对典型桩的最大水平位移、最大加速度响应以及弯矩响应峰值进行对比分析。发现新型架空直立式码头结构的刚度有所增加,尤其是垂岸方向,同时最大水平位移、最大加速度以及弯矩都有所减少,表明新型码头结构型式具有良好的受力特性。In order to study the seismic performance of a new raised vertical wharf,the finite element models of this new raised vertical wharf and the traditional one are built,using the finite element software ABAQUS. Firstly,the modal analysis is applied to two wharf structures so that their natural vibration characteristics can be discussed. Then,in view of the nonlinear influence of the pile-soil interface,the dynamic response of two wharf structures are analyzed.Extracting the horizontal displacements of two wharf slabs,the maximal horizontal displacements of typical piles,the maximal acceleration response and the response peak of bending moments,a comparative analysis is made in this thesis. The findings are as follows： The stiffness of the new raised wharf improved,especially in the vertical direction.Meanwhile,the maximal horizontal displacements,maximal acceleration response and the response peak of the bending moments have decreased,all the above can confirm the good mechanical characteristic of the new wharf.
