摘要: 以一维应力波理论为基础,应用桩土体系相互作用的数值模拟方法,得到了反映桩中应力波的传播过程及反射特性的桩身各点振动速度空间曲面;模拟分析了各类桩身缺陷对桩的振动特性的影响,并将理论曲线与实测曲线进行拟合对比。结果表明:两者基本一致。

Abstract: In this paper, a method of numerical simulation to study interaction of pile-soil based on the one-dimension stress wave theory is applied. The propagating process and reflection characteristics of stress wave under impulsed load in concrete piles are studied. The influence of pile defects to the oscillating properties is also simulated. The validity of this approach is verified through comparison of the measured curve and the simulated curve.
