摘　　要：以某旅游休闲码头工程为依托,以结构安全、节省投资为目标,对常规的高桩梁板式结构,通过优化桩基布置、调整结构分缝型式、设置大刚度靠船块体和挡浪边板,提出一种适应于中小型码头的新型高桩梁板式结构。经技术经济比较,优化后的结构可节省工程投资达623万元。同时针对该结构空间特征显著的特点,对其三维计算模型模拟原则、单元类型选择及桩基与上部结构的连接拟合进行分析研究,给出指导性意见,可为类似项目的结构设计提供技术借鉴与参考。Based on a terminal project for tourism and leisure service,to achieve structural safety and reduced investment cost,the conventional high-piled beam-slab structure is reconstructed to be a new type of structure suitable for small and medium-sized wharves by optimizing the layout of pile foundation,adjusting the pattern of structural joint,adding high-rigidity berthing blocks and wave-retaining side plates.The comparative analysis of techniques and economy shows that the new structure can lower the project cost by 6.23 million yuan.At the same time,in view of significant spatial characteristics of the structure,further analysis and study are carried out for he principle of 3D computational model simulation,the selection of unit types,and the connection fitting between pile foundation and upper structure,and then guiding proposals are made,which will provide a reference for the structural design of similar projects.
