中文摘要：
利用半解析法对移动条形荷载作用下横观各向同性饱和两相弹性介质的动力响应问题进行了研究．由忽略土粒压缩和土体自重的Biot波动方程出发，对荷载进行Fourier级数展开，假设了响应函数的级数形式，利用土体表面边界条件，由待定系数法求解了考虑固液耦合作用的两相介质在移动荷载作用下的土体位移、有效应力及孔压表达式．通过计算，给出了不同土体渗透系数，以及荷载移动速度下横观各向同性对土体位移响应的影响．数值结果表明，横观各向同性对土体位移响应影响较大．
英文摘要：
The dynamic response of a transversely isotropic poroelastic half-space soil medium subjected to moving loads was studied analytically/numerically under conditions of plane strain. The full dynamic poroelastic theory of Biot was employed, under the assumption of an incompressible solid grain and neglecting the apparent mass density. The loading function was presented by a Fourier series expansion. By using the boundary condition at the surface of the soil, the governing equations of motion were then solved. The effect of transversely isotropic on soil vertical displacement were discussed under different parameters such as load speed and coefficient of permeability. Numerical results of vertical displacements were given and indicated that transversely isotropic have much effect on the response of the soil.
