摘　　要：本文根据振动理论和应力波理论，严格推导了各种支承刚度下桩的导纳曲线的特点和特征参数。从理论上和实践上说明稳态机械阻抗法和瞬态机械阻抗法测桩原理的一致性，简述了两种方法的各自优点和适用范围．According to the theory of vibration and stress wave, the character and characteristic parameter mobility curve of pile in all kinds supporting rigid strictly are deduced in the articale. The identity of stable and transient mechanical impedance method is explained in theory and practice. The advantages and application range of the two methods are indicated too.
