摘要 在分析水平层状地基运动特征的基础上 ,运用最小二乘识别理论 ,通过迭代求解基岩输入运动加速度值 ,建立了层状地基参数的时域识别方法 ,并利用地基模型实验数据 ,实施了层状地基的参数识别过程。计算结果表明 ,该方法产生良好的地基参数估计。 On the basis of analyzing the motion characteristic of the horizontal layer foundation and using the identification theory of the least square method, the identification method of the layer foundation parameters is established by solving iteratively the input motion acceleration value. In addition, the identification process of the layer foundation parameters is implemented by utilizing the data of the foundation model experiment. The result shows that the method can yields good estimation of the layer foundation parameters.
