摘　　要：某拖轮码头为高桩梁板式结构,上部结构由预制桩帽、预制横梁、预制面板、预制靠船面板及现浇面板组成,结构复杂,施工困难,浇注质量难以保证,码头结构存在优化的可能性和必要性。通过对设计荷载、桩基结构进行优化,在维持原码头功能要求的前提下,降低桩基内力,重新设计钢管桩壁厚,节省钢管桩钢材用量;将上部结构更改为现浇结构,提高了施工效率和混凝土浇筑质量,节省钢筋用量。该设计优化可供类似项目借鉴。A tugboat wharf is supported on a piled beam-slab structure.Its superstructure is composed of precast pile cap,precast beam,precast slab,precast berthing slab and cast-in-situ slab.Due to complex structure,difficult construction process,it is necessary to optimize the wharf structure so as to ensure concreting quality.By optimizing the design load and pile foundation structure,the internal force of pile foundation is reduced on the premise of the wharf’s functional requirements being met,the wall thickness of steel tubular pile is re-designed to lower the consumption of steel material.Cast-in-situ superstructure improves the construction efficiency and concreting quality,lowers the consumption of reinforcement.The design optimization can serve as a reference for similar projects.
