摘要
对某渡槽结构的拟动力试验模型进行了有限元分析,对比了数值计算和实验结果。首先简要介绍了某渡槽结构的拟动力试验,然后给出了数值模拟的计算模型,对不同类型的地震波在不同峰值条件下的墩身、桩体位移进行了比较,结果表明,有限元计算结果与拟动力试验结果的峰值和变化趋势比较接近,在一定程度上证明了该实验的合理性。
Based on the experimental model of pseudo-dynamic structural simulation analyses and comparison between simulated and experimental test on an aqueduct structure, numerical results were presented. After brief intro- duction of pseudo-dynamic structural test on the aqueduct structure, the simulation model, which is 3D finite ele- ment model with pile - soil interaction base on varied Penzien model, was provided. Then comparisons of pillar and pile displacements under different earthquakes with different peak amplitudes were carried out between test and sim- ulation results. The comparison shows that peaks and change trends of the displacements from test and simulation are close. This verifies that, to some extent, the test is reasonable.
