摘　　要：结合温州港某集装箱码头工程设计,针对环境和自然条件复杂、建设条件差、使用要求高等问题,对超长组合大管桩在深厚软土地区的应用进行研究。分析超长组合大管桩的优点,并通过超长组合大管桩的桩静载荷试验,验证该桩在外海地区深厚软土地质条件下的适用性,确定桩侧摩阻系数和桩尖端阻力,优化桩基布置和桩长设置,大大降低了工程投资。In combination with the design of a container wharf project in Wenzhou Port, and in view of the complicated natural circumstance ＆ environmental condition, poor construction condition, as well as high requirements, we study the application of super long combination large- diameter cylinder pile in the deep soft soil area.Analyzing the advantages of super-long combination pile, and carrying out the static-load test for the super long combination large-diameter cylinder pile, we demonstrate the applicability of the pile foundation in the offshore area with ultra thick soft soil covering, determine the friction coefficient and tip resistance of the pile, optimize the arrangement and length of the pile, and thus greatly reduce the project investment.
