A dynamic interaction schematic of an end bearing or elastic bearing pile with arbitrary force at pile top is founded . by using helmholtz resolution and the operator decomposition method , biot ' s equations governing motions of a porous solid saturated with interstitial fluid are decoupled 建立饱和土中端承桩和摩擦桩在任意激振力作用下的理论模型,利用位移势函数及微分算子分解方法,得到饱和土层biot动力固结方程的分离变量解。
The dissertation discusses some theories of computation including the unit stiff matrix of the spatial member in the local coordinates , the coordinate transformation , the integration of the integer stiff matrix , the equivalent joint load , the introduction of the boundary condition , the computation of the unit internal force and support reaction , the stableness of the spatial stiff frame . the dissertation also discusses the methods of dealing with several unusual problems such as combined structure , temperature stress , elastic bearing 本文论述了空间杆件局部坐标单元刚度矩阵、坐标转换、整体刚度矩阵的集成、等效结点荷载、边界条件的引入、单元内力与支座反力计算、空间刚架稳定的计算理论,以及组合结构、温度内力、弹性支承等几个特殊问题的处理方法。
Finally , dynamic compliances of a pile with variable impedance embedded in layered saturated soil are studied . a simplified layered model is put forward on the basis of the single layer elastic bearing model . by using the same method , analytical solutions in frequency domain hence semi - analytical solutions in time domain representing the dynamic responses at pile head are obtained 基于土层层问相互作用,提出了饱和成层土中任意变阻抗桩的纵向振动问题简化层间模型,利用单层土中提出的解析方法,基于这一简化层间模型,求得饱和成层土中任意段变阻抗桩的桩顶频域解析解和时域响应半解析解,并论证了模型的合理性。
