摘　　要：针对CFRP粘结型锚具理论分析相对滞后的现状,对直筒式粘结型锚具,提出了一种粘结应力的分布模型,并采用解析法分析了其极限承载力,对内锥式和直筒+内锥式锚具,分别采用有限元法分析了其使用荷载下的受力性能,为CFRP粘结型锚具的优化设计提供理论依据和建议。In the light of the present situation that the theoretic analysis of CFRP cable bonding anchors relatively lags behind, a kind of bonding stress distribution model for the straight pipe bonding anchor is put forward, the ultimate capacity of the anchor is analyzed by the analytic method and the finite element method is further used to respectively analyze the mechanical behavior of both the inner cone bonding anchor and straight pipe plus inner cone bonding anchor under service load. The analysis in the paper may provide theoretic bases and advice for the optimal design of the CFRP cable bonding anchors.
