摘要

根据Biot波动理论，采用传递、反射矩阵（TRM）方法研究了移动荷载作用下层状饱和土动力响应问题。由快速Fourier逆变换法（IFFT）得到层状土地基位移、应力及孔压在时间-空间域内的数值解。计算结果与已有文献结果相吻合，验证了算法的正确性。通过算例分析表明：移动荷载作用下含有软弱夹层的层状土体比均质土具有更显著的动力响应，同时会引起土体孔隙水压升高、土体波动性增强；硬夹层时情况则相反。

Abstract

Based on the Biot’s theory

dynamic responses of layered saturated soil under moving loads are studied with the transmission and reflection matrices (TRM) methods. Numerical results of the displacements

the pore pressures and the stresses are obtained by performing inverse Fourier transformation in time-space domain. Some numerical examples and corresponding analysis are presented. The presented methodology is validated by comparing solutions with some known results. According to the analysis

it is concluded that the occurrence of softe interlayer in the layered half space enhances the vertical displacement and pore pressure. Comparing with the homogeneous soil

the response of the multi layered half space tends to contain higher frequency components and exhibits larger magnitude.
