Abstract: For research on the ultimate bearing capacity of shallow foundation on slope, it uses the finite element analysis with the multiple zero-thickness interface elements which considers the Coulomb’s failure criterion. The influence factors of ultimate bearing capacity, slope angle and distance from the slope margin are particularly studied. The minimum upper bound of bearing capacity and the behavior of progressive failure are also investigated in this research. The ultimate bearing capacity calculated in this study is taken account that shallow foundation is seated on (1) the semi-infinities ground, (2) the slope margin and (3) the distance from the slope margin. The results obtained shown that the ultimate bearing capacity of shallow foundation decreases as the values of influence factors decreases. In other words, while the shallow foundation seated on the slope margin during the vertical slope excavation, the value calculated of ultimate bearing capacity decreases about 50 % less than that obtained by the case of semi-infinities ground.

Key words: upper bound limit analysis, zero-thickness interface element, shallow foundation on slope, finite element analysis, progressive failure
