摘　　要：为促进碳纤维增强复合材料(CFRP)这一具有密度小、抗拉强度高、抗疲劳、耐腐蚀等特性材料的研究工作与在土木工程结构中的实际应用,主要介绍了各国有关CFRP筋及其锚具研究和应用的最新进展,分别对粘结型、夹片型、复合型3类现有的主要类型锚具的锚固机理、代表性试验研究和数值分析等方面做了整理和归纳,并提出了锚具开发和应用的一些关键问题和建议。In order to promote the future research and application of carbon fiber reinforced polymer （CFRP） for civil engineering structures, with the characteristics of low specific gravity, high tensile strength, high fatigue resistance and corrosion resistance, an introduction was given on the latest research and application progress of CFRP tendon and anchors for all countries. The anchorage mechanism, typical experiment investigations and numerical analysis of exist main types of anchors, including bond-type anchor, wedge-type anchor and wedge-bond anchor, were also classified and summarized. Finally, some critical problems and advices in anchor development and utilization were provided.
