摘　　要：本文基于一种性能优异的组合结构——钢管混凝土,分析了钢管混凝土的优点,对近年来在桥梁工程中钢管混凝土在一些桥型中的应用科研成果进行简单描述,并阐述了当前该领域存在的问题和未来发展方向。结果表明:钢管混凝土在承载力、抗震性等诸多方面有明显优势,可以使混凝土和钢管的性能充分发挥,但随着研究应用的加深,钢管混凝土结构仍存在大尺寸构件的尺寸效应、浇灌混凝土时产生的钢管初应力、受到扭转和弯曲耦合作用处的节点受力、防止混凝土脱空和桥梁上部结构预制拼装施工等问题有待解决。望本文能为今后钢管混凝土研究提供思路和方向,为钢管混凝土的推广应用提供数据和理论支持。This article is based on a high-performance composite structure-steel concrete.It analyzes the advantages of steel-concrete and briefly describes the research achievements in the application of steel-concrete in some bridge types in recent years.It also elaborates on the current problems and future development directions in this field.The results show that steel-concrete has significant advantages in bearing capacity,seismic resistance,and other aspects,which can fully utilize the performance of concrete and steel pipes.However,with the deepening of research and application,there are still problems to be solved in steel-concrete structures,such as the size effect of large-sized components,the initial stress of steel pipes generated during pouring concrete,the joint force subjected to torsion and bending coupling,the prevention of concrete void,and the prefabrication and assembly construction of bridge upper structures.I hope this article can provide ideas and directions for future research on steel tube concrete,and provide data and theoretical support for the promotion and application of steel tube concrete.
