摘要: 基于地基土存在着固有各向异性和诱发各向异性 ,本文采用横观各向同性弹性体模型模拟地基半空间 ,将Love位移函数推广到半空间 ,得到位移与位移函数之间的关系 ;然后经过Hankel变换得到非轴对称问题位移、应力的一般解。本文的一般解经过退化 ,得到的轴对称弹性半空间解与经典解吻合。Abstract: Based on the inherent anisotropy and induced anisotropy of soil,transversely isotropic elastic constitutive relations are adopted to simulate elastic half-space of foundation.The relation between displacement and displacement function is proposed by extending Love displacement function to transversely isotropic elastic half-space. Then the general solutions of stress and displacement for non-axisymmetric problems are obtained by Hankel transformation. The axisymmetric elastic half-space solutions evolved from the general solution in this paper are in accordance with the classical ones.
