中文摘要：

通过试验研究了碳纤维增强复合材料（CFRP）筋在活性粉末混凝土（RPC）中粘结应力沿埋长的分布，得到了CFRP筋在RPc中的应力-应变关系、荷载-滑移关系以及粘结应力沿埋长的分布曲线，并建立了粘结应力的位置函数计算式。在试验研究的基础上，从粘结锚固性能的平衡方程、变形方程以及本构方程出发，推导了粘结应力、CFRP筋轴向应力、滑移量以及位置函数等锚固变量沿锚长分布的理论计算公式。结果表明：粘结应力和CFRP筋应力沿埋长分布的实测曲线与理论推导预测曲线吻合较好，理论推导具有可行性；CFRP筋轴力沿埋长线性增加；CFRP筋在RPC中的粘结应力沿埋长分布较为均匀；钢套筒的存在使得粘结应力分布趋向于更加均匀；混凝土抗压强度和CFRP筋直径越大，粘结应力沿埋长分布越均匀；锚固长度越大，粘结应力沿埋长分布越不均匀；弹性模量越大，粘结应力沿埋长分布越均匀，且以CFRP筋的弹性模量对粘结应力分布的影响最大，钢套筒的弹性模量次之，混凝土的弹性模量最小。

英文摘要：

The bond stress distribution of carbon fiber reinforced polymer/plastics （CFRP） tendon in reactive powder concrete （RPC） along bond length was studied. Based on experimental research, relations of CFRP tendon stress-strain, CFRP tendon load-slip and bond stress distribution along bond length could be presented. The equations of bond stress distribution function of position were gained due to the test results. Based on the equilibrium equations of bond anchor behavior and the deformation equation of linear elastic relationship between stress and strain and constitutive equation of load-slip of CFRP tendon in RPC. Calculated formulae of distribution of the bond stress, CFRP tendon axial stress, slip and function of position along bond length could be presented. Result shows that experimental curves and theoretical curves of bond stress and CFRP tendon distribution along bond length show good agreement. Theoretical deduction is feasible. CFRP tendon axial force along bond length increases linearly, bond stress distribution along bond length for CFRP tendon is uniform. Steel sleeve can make bond stress distribution more uniform. When the parameters, such as concrete compressive strength and CFRP tendon diameter increase, bond stress distribution is more uniform. But bond stress distribution makes more non-uniform with increase of bond length. In addition, the more elastic modulus makes bond stress distribution more uniform. For the influence of the elastic modulus on bond stress distribution, the CFRP tendon is the largest, and steel sleeve is less, and concrete is the least.
