| 摘 要： | 目前关于地基阻抗的分析和计算方法都比较繁琐,不易为工程设计人员所掌握.基于此,提出了埋置基础地基阻抗函数的简化计算方法.首先,采用锥体模型分析均质半空间内埋置圆盘一维振动波的传播过程,得到了平动和转动时的地基阻抗.在此基础上,利用埋置圆盘组来模拟埋置基础,分析得到了埋置基础地基阻抗函数.最后,通过算例表明此方法计算效率高,误差小,适用于工程计算. |

| Abstract: | Analysis and calculation methods for impedance function of a foundation are complicated,and it is difficult for engineering designers to grasp and use them.A simplified method was proposed here to calculate impedance function of a foundaton embedded in a half-space.Firstly,based on a cone model,one-dimensional vibration wave propagating of a rigid massless circular disk embedded in a homogeneous half-space was analysed.Impedance functions of translational and rotational cone models were derived.Then,the emb... |
| Keywords: | cone model block foundation impedance function embedded foundation soil-structural interaction |
