摘　　要：建立完整锚杆低应变瞬态动力响应的数学力学模型并推导出相应的半解析解,研究分析了不同参数对锚杆顶端瞬态动力响应的影响,并将瞬态激振条件下得到的理论曲线与反射波法测得的实际曲线进行了拟合对比,结果表明两者吻合很好。The small strain dynamic response of integrate anchor bar under impulse force is studied, the corresponding semi-analytical solution is developed by using Fourier transform method. The influence of different dynamic parameters on dynamic response of top end of the anchor bar is analyzed, and the theoretical curve is in good agreement with that obtained from the field measurement.
