| 摘 要： | 采用动力文克尔地基模型模拟均质粘弹性土层，推导出了均质土中单桩动阻抗；引用桩-桩动力相互作用因子，得到了刚性承台下群桩的动阻抗；而且建立了柔性承台与桩基础的竖向振动模型，该模型考虑了筏板自身的变形，并导出了其共同作用的运动方程。最后对柔性承台与刚性承台的计算结果作了对比分析。

| Abstract: | The dynamic impedance of a single pile embedded in homogeneous viscoelastic soil deposits is obtained by using the dynamic Winkler model. And the dynamic impedances of rigidly-capped pile groups are derived by (adopting) the dynamic interaction factor. Also, the dynamic model is accounted for axial vibration between the pile groups and raft foundations. The flexibility of raft is considered. Then, the equation of motion of interaction between the pile groups and raft foundations is worked out. Finally, the results are obtained by calculating the dynamic response in both of a rigid cap and a flexible one. |
