| 摘 要： | 假设地基土体为弹性,不可压缩,剪切模量随深度线性变化,采用Hankel 变换,得到了下卧为岩层,表面分布一般轴对称荷载的地基土体应力位移积分形式解,应用数值方法,就地基的非均质性、岩层深度对位移的影响进行了讨论。获得的解可以退化到半空间情况。

| Abstract: | In this paper we present the exact analytical solutions for displacements and stresses of an isotropic non-homogeneous elastic subgrade on rock subject to an axisymmetric surface load. It is assumed that the soil of the subgrade is incompressible and that the shear modulus varies linearly with depth. Selected numerical results for vertical displacements are presented to describe the influence of the degree of non-homogeneity、depth of rock of the non-homogeneous subgrade. Hankel integral transforms are used in the analysis. |
