内部構造を考慮した弾粘塑性構成式による粘土地盤支持力の有限要素解析

Computing and analysis methods of bearing capacity conventionally used nowadays do not consider the effect of microstructure change of clay which leads to softening of soil strength and strain localization. The strain localization is generally considered to be important as a sign of failure and therefore the effect of microstructure cannot be neglected. In the present study, the finite element analysis of bearing capacity of surface foundation on homogeneous saturated clay stratum is conducted using an elasto-viscoplastic soil constitutive model considering microstructure change. Finally, the effect of microstructure change on collapse load and load-deformation behavior in bearing capacity problem is evaluated.
