| 摘 要： | 根据桩在瞬态激振方式下的阻尼波动方程,本文分别给出端承柱与浮承桩的振动初始条件和边界条件,并导出了两类桩瞬态动测响应的数学模型.通过与试验桩实测响应的对比,证明所建立的数学模型是正确的.文中还分析和讨论了桩的瞬态动测响应的五个基本特性,为动力测桩的参数估计提供了较严格的理论依据.

| Abstract: | Under conditions of transient shock the mahematical models of vibration response are established in accordance with the damped Wave-Equation and boundary and initial conditions for the end-fixed pile and friction pile. These models are proved to be correct by comparing computed response with measured response for the same experiment pile. Finally, five characters of vibration response are discussed and analysed in detail. These characters, obviously, are essential and theoretical bases for evaluating and inverting parameters of pile in dynamic test. |
