利用数值法和闭合解建立了桩土系统的振动微分方程组，编制了ＤＲＰ－１动力响应分析软件，使理论计算桩顶的速度时域曲线和传递函数频域曲线与实测曲线双重吻合，给计算结果提供了可靠的保证。本文方法特别适用于大型桥梁桩基工程和土木建筑工程的动力测试。
The vibration differential equations of pile-soil system are established by numerical method and closed solution, and the DRP-1 dynamic response analysis software is compiled. The theoretical calculation of pile top velocity and time domain curve and transfer function frequency curve coincide with the measured curve. The results provide a reliable guarantee. This method is especially suitable for dynamic testing of large-scale bridge pile foundation engineering and civil engineering.
