摘　　要：高桩码头在我国沿海地区应用十分广泛,许多因素都会对其结构产生不利影响.利用有限元分析软件PLAXIS,采用Mohr-Coulomb准则建立了某高桩码头岸坡-桩基-上部结构的数值模型,分析了码头上部结构在面板堆载、船舶靠泊、泥沙淤积和地震荷载多因素耦合作用下结构内力和变形规律.分析结果表明:多因素共同作用下,高桩码头上部结构有较大的水平位移,且泥沙淤积作用下结构水平位移更为严重.同时,地震荷载和泥沙淤积是影响上部结构安全性的主要因素,结构的最大内力均发生在桩基顶部,在高桩码头设计施工中要重点关注桩基顶部的结构设计.High pile wharf is widely used in China′s coastal areas,and many factors will have adverse effects on its structure.Based on the finite element analysis software PLAXIS and Mohr-Coulomb criterion,a numerical model of bank slope,pile foundation and superstructure of a high pile wharf is established.The internal force and deformation laws of the wharf superstructure under the multiple factor coupling action of panel loading,ship berthing,siltation of sediment and seismic load are analyzed.The analysis results show that the superstructure of high pile wharf has a large horizontal displacement under the action of multiple factors,and the horizontal displacement is more serious under the action of siltation of sediment.At the same time,the seismic load and siltation of sediment are the main factors affecting the safety of the superstructure,and the maximum internal force of the structure occurs at the top of the pile foundation,so it is necessary to pay attention to the structural design of the top of the pile foundation in the design and construction of the high pile wharf.
