摘要
钢管混凝土(CFST)具有承载力高、施工方便和抗震能力好等优良性能,在国内外桥梁工程中得到较为广泛的应用。全面地总结了钢管混凝土结构在梁式桥、拱桥、斜拉桥等多种桥型中的应用情况,并着重探讨了钢管混凝土桥墩的研究和应用现状。介绍了"部分钢管混凝土"桥墩的试验结果。探讨了钢管混凝土结构应用于桥梁工程中还有待解决的主要问题。最后对钢管混凝土在桥梁工程中的应用前景作了展望。
Concrete filled steel tube (CFST) is used widely in modern bridges at home and abroad for its excellent characteristics, such as high strength, convenient construction and good seismic behavior. The applications of CFST in various bridge types are summarized comprehensively, such as girder bridges, arch bridges and cable-stayed bridges. Moreover, a research and present application review on is given with emphasis on concrete filled steel bridge piers. The test result of partial concrete filled steel bridge piers is presented briefly. Some main issues to be researched on CFST are discussed. In the end, the prospects for application of CFST in bridge engineering are previewed.
