Abstract
In this study, with the distinct element method analysis in threedimensional state, simulations of the true triaxial test for spherical granular material is carried out. In this analysis, the influence of meniscus water, which is mainly cause of the complicated behavior of unsaturated soil, is expressed by introducing a constant intergranular adhesive force that acts perpendicular to the tangential plane at contact point. The influence of the intergranular adhesive force on the failure criterion and deformation are examined. From the analytical results, it is found out that not only the failure criterion but also deformation characteristic in shear process are obey to the Lade failure criterion.
