摘要
将常扰力作用下的单桩视为非线性单自由度体系，采用等效线性化方法，列出非线性振动微分方程。利用动力反应曲线的几何性质反演计算各振动参数，并由模型桩动力试验实测结果加以验证。
Being considered as a nonlinear system with one degree of freedom, a nonlinear differentialequation of single piles was founded by equivalent linearization. Based on the geometric properties of dynamic response curves, the vibration parameters were backcalculated and verified by vibration test results of model piles.
