| 摘 要： | 基于饱和地基多孔介质理论,考虑了水土的惯性及耦合作用,研究了横观各向同性饱和地基的稳态振动问题。利用Hankel变换,得到饱和土的位移、应力、孔压的积分形式的解,由此利用数值Hankel逆变换给出了数值算例,最后讨论了横观各向同性饱和地基各向异性对地表竖向振幅的影响。

| Abstract: | Based on the saturated porous medium’s theory, the inertia force of both the soil and the water is considered; the stable vibration problem of transversely isotropic saturated soils is studied. Hankel transform is used to obtain the displacement, stress and porewater pressure in integral form. The numerical inversion of Hankel transform is used to obtain some numerical results. Finally, the effect of the type and degree of soils anisotropy on the vertical amplitude of displacement is investigated. |
