一种基于Gibson土的改进Vlasov地基模型

A Modified Vlasov Soil Model in Gibson Soil

对 Gibson土中的 Vlasov双参数地基模型进行了改进 ,导出了相应的特征函数 ,并就集中及均布条形荷载下土中内力及地面位移进行了分析 .结果表明 ,土体的非均匀性对其内力与位移影响较大 。

A modified Vlasov two-parameter soil model in Gibson soil is developed and the corresponding soil response function is derived.The stresses and the surface displacements of the soil subjected to a line load and a uniform strip load are analyzed.The results show that in some cases the inhomogeneity of soil affects the stresses and the surface displacements considerablely and should be taken into account.
