PHC管桩单桩振动台试验与数值模拟对比分析

Contrastive Analysis on Shaking Table Tests and Numerical Simulation of Single PHC Tubular Pile

    摘要
  • 摘要: 利用振动台对PHC管桩进行单桩承台模型试验;同时将土体-PHC管桩-上部结构视为共同工作整体,建立三维有限元模型,再以ABAQUS软件为计算平台,对单桩试验工况下的地震反应进行数值模拟计算,并将试验结果与数值模拟计算结果进行对比分析。结果表明:数值模拟和振动台模型试验基本吻合,两者得到的地震反应影响体现出相似的规律性,印证了模型试验的可靠性和数值模型的合理性。

     

    Abstract: Single pile cap model of PHC tubular pile is tested on the shaking table and 3 Dfinite element model is established considering the soil-PHC tubular pile-superstructure as integrity.The ABAQUS software is taken as calculation platform to numerically simulate the seismic responses under single pile test conditions.The simulation results and the shaking table rest records are compared in detail.It indicates that the simulation results are basically identical with those of shaking table tests,and both of them reflect similar seismic response regularity.The reliability of model tests and rationality of numerical simulation are proved.
