| 摘 要： | 以建立的纤维增强塑料锚杆在岩土体中的粘结锚固基本方程为基础,结合纤维增强塑料锚杆的连续光滑粘结–滑移本构关系模式,提出了纤维增强塑料锚杆锚固性能分析的数值计算方法,并通过与FRP锚杆锚固试验结果对比确定有关参数。将数值计算结果与锚固试验结果以及理论计算结果进行了对比分析,验证了数值模拟方法的正确性。

| Abstract: | Based on the theoretical differential equations of fiber reinforced plastic(FRP) bolts anchored in the rock,and combined with the continuous smooth bond-slip curve of FRP,the nonlinear numerical calculation method is put forward.The concerned parameters can be determined by comparing the calculating results with those of anchorage behavior tests.Moreover,the numerical simulation results are contrasted with the theoretical ones,and the validity of the numerical simulation method is testified. |
