| 摘 要： | 通过考虑酸、碱、盐、冻融循环环境影响后的碳纤维增强材料CFRP锚杆粘结性能试验,拟合不同环境粘结-滑移(τ-s)关系表达式;并基于试验参数,采用ANSYS非线性弹簧单元Combin 39模拟CFRP锚杆粘结单元,引用拟合τ-s关系曲线确定弹簧单元荷载-位移(F-S)关系参数;模拟分析与试验结果对比表明:由本试验拟合的τ-s关系曲线能很好地反映CFRP筋与环氧砂浆受特殊环境影响后粘结性能的变化。为经常处于特殊环境下的CFRP锚杆性能分析、设计理论及工程应用提供理论依据,也可为相关规范的编制和完善提供参考。

| Abstract: | Through the CFRP anchor bond performance test after acid,alkali,salt,freeze-thaw cycle environmental impact,fitting different environment bond-slip relational expression and also based on the test parameters,CFRP anchor bond unit was simulated with nonlinear spring element Combin 39 of ANSYS.The fit τ-s curve was used for determining F-S relation parameters of the spring unit.The comparison between the simulation analysis and experimental results showed that the fit bond-slip relation curve could reflect well the CFRP reinforcement and epoxy mortar performance changes after acid,alkali,salt,freeze-thaw cycle environmental impact.Which provided a theoretical basis for performance analysis,design theory and engineering application of CFRP anchor under special environment,also provided a reference for compiling and perfecting relevant norms. |
