装配式海岸工程混凝土结构研究与应用进展

Progress in Research and Application of Precast Concrete Structures in Coastal Engineering

码头和防波堤建筑物是典型的海岸工程混凝土结构。这类结构的下部结构构件多为预制,而上部结构构件多为现浇。针对3类典型装配式海岸工程混凝土结构(高桩码头、板桩码头、桩基透空式防波堤),系统介绍了其结构特点、典型节点与连接构造,总结分析了国内外有关这3类典型结构的力学性能、技术标准与工程应用的最新进展。最后,对今后装配式海岸工程混凝土结构的应用与研究前景进行了展望。

Wharfs and breakwaters are the typical coastal concrete structures.These structures commonly use precast members for their supporting structure,while,their superstructures usually use cast-in-place concrete structural members.In this paper,the structural characteristics,typical precast connections and detailing in three typical coastal concrete structures(high-pile wharf,sheet-pile wharf,and permeable breakwater on piled foundation)are introduced.Then,the state-of-art studies are conducted on the mechanical behavior,technical standards and application at home and abroad of three typical coastal concrete structures.Finally,the research and application prospects of precast coastal concrete structures are presented.
