This study evaluated the uplift behavior of anchor foundation buried under slope surface by comparing a conventional 1 g-model test with a 3D unite element analysis. The ground surface was arranged to be inclined at the angle (i) of 0, 10, 20, and 30 degrees. The anchor foundation was a flat circular 1cm thick steel plate with a diameter of 10cm and a height of testing bed was 10cm. The 3D finite element analysis employed a constitutive model in which non-associated strain hardening-softening elasto-plastic material was assumed. The 3D finite element analysis was available to predict the anchor foundation behavior under slope surface. The ultimate uplift resistances decreased when angle of i exceed 20 degrees. The rupture plane was tilted to the lower side according to the angle of slope surface increased.
