整体推进式桩基码头结构设计与施工

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。

Design and construction of wharf with pile foundation under cantilever construction methods

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.
