摘　　要：意大利威尼斯离岸深水港项目拟在外海建设现代化全自动集装箱港区,其关键技术之一是在深厚高压缩性土体且广泛存在极软弱泥炭夹层的极不均匀和复杂地质条件下,采用何种码头结构形式才能满足全自动化集装箱码头较高的使用要求。为此,对高桩码头+组合式桩基承台驳岸结构、重力式沉箱结构和全高桩(高桩码头+高桩堆场)结构3种方案进行综合比选,并利用有限元数值模拟分析,提出采用全高桩码头结构形式。该结构形式适合工程的地质条件和使用要求,技术成熟,风险小,且投资较低。A fully automated container port is to be built in Venice offshore,Italy.One of the key technologies of the project is to select a proper structural type for the wharves to resist the action of deep and highly compressible soil and peat layers.The paper compares the differences of 3 structures,i. e. the high-piled wharf ＋ combined pile platform connecting shore structure,gravity caisson structure,full pile-supported beam and slab（ high-piled jetty ＋high-piled yard） structure,analyzes them by the finite element analysis software,and proposes the structural type of full pile-supported beam,which is suitable for the geologic condition and can meet the application requirement due to its mature technology,little risks and low cost.
