有限长桩受迫振动问题解析解及其应用

Analytical Solution to Vibfration of Finite Length Pile Under Exciting Force and Its Application

  • 摘要: 本文首先求出桩长有限、桩端为弹性支承时,考虑桩侧土作用,桩顶受稳态正弦激振条件下,基桩纵向振动问题的解析解;其次利用迭加原理求得了瞬态半正弦激振条件下的解析解;然后对所得解进行了研究分析,得到了许多重要结论。最后,将瞬态激振条件下得到的理论曲线与反射波法测得的实际曲线进行了拟合对比,结果表明两者吻合很好。

     

    Abstract: The vibration problem of finite length foundation pile under exciting force taking account of rheological properties of the surrounding soil is studied, and the corresponding analytical solution is developed.  Based on the solution, the influences of the parameters of pile and soil on the vibration are analysed and some relevant conclusions are drawn.  the theoretical curves are in good agreement with that obtained from the field measurement.
