摘要
基于扩散虚土桩模型,对均质饱和土中大直径桩的纵向振动特性的可行性进行研究。通过桩和饱和土体的动力方程,求解出桩的速度时域响应函数。在相同情况下进行室内试验和ANSYS数值模拟,得出试验解和数值解,与理论解进行对比。对比结果显示,试验曲线与理论曲线几近重合,数值曲线与理论曲线也吻合较好,从2个方面验证了理论解的可行性,对实际工程具有指导意义。
Based on diffused fictitious soil pile model, feasibility study on vertical vibration characteristics of homogeneous saturated soil in large diameter pile is carried on.The time domain response function is obtained by dynamic equations of piles and soil. In the same case, the indoor test and ANSYS numerical simulation are carried out, and the experimental and numerical solutions are obtained to compare with the theoretical solution.The comparison results show that the experimental curve is almost coincided with the theoretical curve, and the numerical curve agrees well with the theoretical curve, too. It confirms the feasibility of the theoretical solution from two aspects, and has guiding significance for practical engineering.
