摘要
根据横观各向同性体的基本方程,运用应力函数、傅氏变换和傅氏逆变换理论,得出了横观各向同性地基在水平集中荷载作用下的基本位移解,然后利用积分的方法分别得出了横观各向同性地基在条形面积上水平均布荷载、水平三角形分布荷载及水平梯形分布荷载的位移计算公式,并利用实测的一组弹性参数,将横观各向同性地基中的相对位移与现有的计算理论给出的各向同性地基中的相对位移通过图形作了分析比较,得出了一些有益的结论,以供岩土工程设计人员参考.
Based upon the general equations of a trans-versely isotropic foundation, the stress functions and the theory of Fourier transforms, the basie displacement so-lutions for a transversely isotropic body under horizontal concentrated loads are obtained. By integration, the displacements caused by horizontal uniform, trianglar or trapezoid distributed loads acting on the strip area of a transversely isotropic foundation are obtained. With mea-sured elastic constants, graphs of relative horizontal dis-placements of a transversely isotropic foundation are com-pared with those of an isotropic foundation. Some valu-able conclusions are drawn.
