英文摘要	In this paper, two-dimensional finite element analysis of strip surface foundations resting on undrained two-layered subsoil under the effect of combined vertical (V) and moment (M) loading has been applied to investigate the ultimate bearing capacity and failure mechanism of the subsoil. In this analysis the material response of the soil was represented with elastic perfectly plastic constitutive law yielding according to Mohr-coulomb failure criterion. The surface foundation is assumed to have no uplift capacity, and the footing may detach from subsoil under a V-M load combination, which is significantly different from the fully attached footing. The ultimate bearing capacity of the foundation on layered subsoil is presented in terms of the failure envelope in vertical and moment loading space. The effects of the thickness of upper soil, the width of footing and the shear strength of soils on the shape of the failure envelope are examined in details. It is found that the shape of failure envelope is mainly depended on the thickness of upper soil and the undrained shear strength ratio of two layers.
