摘要

    摘要
  • 摘要: 为研究桩-土系统中各物理参数对桩基动力学特性的影响,基于建立的考虑土-结构相互作用效应的桩基动力学模型,对桩基的主共振响应进行了计算分析。进而,利用统计分析的方法研究了主要物理参数对动力响应有效非线性系数的影响,判定出具有显著影响效应的关键参数。最后,对比研究了关键及非关键参数对桩基主共振幅频响应的影响,验证了动力学参数效应分析的正确性和重要意义。
    Abstract: Based on the dynamic model of a pile foundation accounting for the effects of soil-structure interaction, the primary resonance of a pile foundation is investigated. To analyze the effects of main parameters on the dynamic properties of the pile foundation, the effects of these main physical parameters on the effective nonlinear coefficient are examined via a statistical analysis method. Then, the key parameter with the most significant effect on the dynmainc response is selected. Finally, through the numerical results of the comparative study on the influence of the key and non-critical parameters on the frequency-response curves of the primary resonance, the correctness and significance of the kinetic parameters analysis are verified.
