Earthquake disasters can threaten human life and cause property damage. The dynamic analysis of the ground performance of the seismic field is essential. In this study, numerical analysis is used to predict the dynamic behavior and response analysis of large-scale models under different seismic waves. Firstly, the accuracy of numerical analysis is verified by a 1 g shaking table test under the same size. Then, according to the similarity law, numerical analysis is used to obtain the dynamic behavior of the model at different scales. The results show that the 1 g shaking table test results are in good agreement with the numerical analysis results and that the numerical analysis can predict the dynamic behavior of the scale model. The 1 g shaking table test provides a valuable method for evaluating the numerical analysis, which captures the complex behavior and resolves uncertainties, ultimately leading to more robust and reliable analyses.
地震灾害会威胁人类生命并造成财产损失。对震区地面性能进行动态分析至关重要。在本研究中,采用数值分析来预测不同地震波作用下大型模型的动态行为和响应分析。首先,通过相同尺寸的1g振动台试验验证数值分析的准确性。然后,根据相似定律,利用数值分析获得不同尺度模型的动态行为。结果表明,1g振动台试验结果与数值分析结果吻合良好,数值分析能够预测比例模型的动态行为。1g振动台试验为评估数值分析提供了一种有价值的方法,该方法能够捕捉复杂行为并解决不确定性问题,最终实现更稳健、更可靠的分析。
