锤击桩的定向稳定性问题

PROBLEMS IN THE DIRECTIONAL STABILITY OF DRIVEN PILES

  • 摘要: 为了讨论锤击桩在打入时的定向稳定性,本文发展了一种分析方法。由假定桩顶的作用力呈周期变化从而导得Mathieu方程。对于不同类型的土,桩的临界长度可以以Mathieu方程的稳定界限得到。恒定作用力的情况可以作为本文的一个特例。

     

    Abstract: In this paper, an analytical method is developed in order to discuss on the directional stability of driven piles. We let driving forces at the pile top be periodic change and the Mathieu equation is derived. For various kinds of soils, critical lengths can be obtained from stability charts of the Mathieu equation. The case in which the driving force at the pile top is constant can be taken as a particular example of this paper.
