摘　　要：碳纤维增强复合材料(CFRP)作为一种新兴的建筑材料,由于具有质量轻、抗拉强度高、抗疲劳性能好、耐久性能佳等优点,受到广大土木工程人士的喜爱。现如今,钢制缆索普遍存在耐腐蚀性和抗疲劳性能差、承载力不足、温度变形大等问题。若将特殊工作环境中的钢制缆索替换为CFRP拉索,不但能解决钢制缆索的结构耐久性问题、提升桥梁的综合性能,而且能使桥梁结构变得更加轻盈和美观。首先介绍了纤维增强复合材料(FRP)的特性、分类及其主要生产工艺,然后介绍了CFRP索支桥梁结构的分类、重点研究成果及其工程应用,最后对CFRP索支桥梁结构的发展前景进行了展望。As a new building material,carbon fiber reinforced composite(CFRC)has been favored by many civil engineers because of the advantages of light weight,high tensile strength,good fatigue performance and good durability.Nowadays,steel cables generally have problems such as corrosion resistance,poor fatigue resistance,insufficient bearing capacity,and large temperature deformation.If the steel cables under special working environment are replaced with CFRP cables,it will not only solve the structural durability problem of the steel cables and improve the comprehensive performance of the bridge but also make the bridge structure lighter and more beautiful.This paper first introduces the characteristics,classification and main production process of fiber reinforced composite materials,then the classification,key research and engineering application of CFRC cable-supported structures.Finally,it looks forward to the development prospects of CFRP cable-supported bridge structures.
