摘　　要：针对在拉美和非洲地区部分码头建设中,存在大型船机设备缺乏和长周期波较为明显、常规打桩船作业和预制构件安装困难的问题,基于一般桩基码头结构,在设计和施工两个方面进行优化,采用桩顶施工行走平台方法施工,利用桩基自身作为支撑结构,大量采用叠合式上部结构,实现将海上施工转化为陆上施工的创新,形成整体推进式桩基码头结构,规避大型船机设备缺乏和长周期波较为明显的问题,具有良好的经济性和对强震区的适应性。The wharf construction has many problems in Latin America and Africa, such as lack of large-scale ship equipment and poor offshore construction conditions （long-period wave）. Meanwhile, the operation of conventional piling and the installing of prefabricated components are both difficult. Based on the general structure of pile wharf, we optimize design and construction of the structure, adopt a self-traveling platform by cantilever construction method, use the pile foundation as supporting structure, and also adopt composite beams and slabs.The method transforms the construction into activities on land as an innovation, establishes a new structure as wharf with pile foundation under cantilever construction method, avoids lack of large-scale ship equipment and poor offshore construction conditions（ long-period wave）. The method shows its well economical efficiency and applicability in meizoseismal area.
