| 摘 要： | 采用横观各向同性层状粘弹性模型模拟半空间之上的层状场地, 用阻尼器取代其下部半空间以吸收振动能量。利用作者所推导的环形荷载作用下横观各向同性层状场地位移响应公式, 将它们沿径向进行积分, 给出了横观各向同性层状场地对圆盘状简谐荷载位移响应的一般形式, 并举例说明一些参数及底面边界条件对这些响应的影响。

| Abstract: | A model of transversely isotropic elastic strata is used to simulate the soil layers situated on a half space. At the bottom of the strata, dampers are used to absorb vibration energy. By using the formulas of displacement responses of transversely isotropic elastic strata to harmonic ring loads, the general formulas of displacement responses of transversely isotropic elastic strata to harmonic disk loads are derived. To examine the effects of some parameters and boundary conditions on the responses of soil layers, several numerical examples are given. |
