摘　　要：本文在分析了国内外已有的CFRP棒材锚具基础上,介绍了一种新型灌注式锚具的特点和性能,重点进行了CFRP筋-锚具组装件静载试验,在此基础上,提出了CFRP筋效率系数、锚具效率系数计算方法,讨论了CFRP筋-锚具组装件和预应力钢筋-锚具组装件锚固性能的差别,研究成果可为CFRP筋的应用及相应规程编制提供参考。Based on the existing research of CFRP tendon anchorages, the performance of one new grouttype anchorage was studied. The performance and anchoring capacities of CFRP tendon-anchorage system were tested. In this paper, the anchorage efficiency coefficient formula of CFRP tendon-anchorage system and the method to calculate the efficiency ratio of CFRP tendon were suggested. And also, the anchoring peformance of CFRP tendon-anchorage sysytem and prestressing steel tendon-anchorage assembly was compared. This research can be used as reference to the application of CFRP tendon and drawing up national code.
