摘要

摘要: 针对地基土弹性模量随深度线性增加的非均质地基,推导出圆形竖向均布荷载作用下的竖向位移近似计算公式。通过与Gibson地基解、均质地基解、有限元结果的对比分析,结果表明了竖向位移近似解的正确性,并对土体的泊松比、非均质参数对竖向位移的影响规律进行探讨。

Abstract: The approximate displacement solution has been provided for non-homogeneous soil mass,whose elastic modulus increases linearly with depth,which is subjected to a circular of vertical uniform load. The accuracy of this solution has been verified through comparison with that of Gibson soil,homogeneous soil and finite element approach. In addition,the effects of Poisson's ratio and degree of non-homogeneity on vertical displacement are discussed.
