摘要
本文将桩的波动方程考虑为线性的，而将埋入土中一端的边界条件考虑为非线性的，用摄动法对稳态激励进行响应分析。求出了桩—土系统动力学方程的近似解析解，对桩基的无损检测和地震分析均有参考价值。
In this paper, the wave equation of pile is assumed to be linear, the boundarycondition is nonlinear, the response of stability excitation is analysed by the perturbation method. An approximate solution of the dynamic equation for pile-soil System is obtained which can be applied m pile foundation and earthquake analysis.
