| 摘 要： | 在分析水平层状地基运动特征的基础上, 通过研究地层系统的特征值和特征向量与地层参数之间的关系, 修正测量得到的数据与理论计算结果之间的偏差, 建立了层状地基参数的频域识别方法。并利用大型振动台上的地基模型试验数据, 实施了层状地基的参数识别过程。结果表明, 该方法产生良好的地基参数估计。

| Abstract: | On the basis of analysis of the movement characteristics of horizontal layered foundation and the relationship between soil parameters and eigenvalues and eigenvectors of the soil system, frequency domain identification method of the layered foundation parameters is suggested by correcting the deviation between the measured soil data and theoretical calculation results.In addition, the frequency identification process of the layered foundation parameters is performed by using the data from foundation model experiment. The result shows that the method can yields good estimate of the layer foundation parameters. |
