Abstract: By analyzing the micromechanics of the two-dimensional ideal particles (disc)under direct shear test,the movement during the shearing is investigated.The formula described the maximum shear stress in the regular dense packing condition is established.In addition,following the direct shear simu-lations of the four samples with different particle size distributions,application of the formula which could predict the maximum shear stress was discussed.The results show that the maximum shear stress is de-pending on two parameters namely boundary effect parameter and the non-boundary effect parameters, and these two parameters keep the same under the regular dense packing when the vertical loading is con-stant.For the general packing,the boundary effect parameters remained unchanged,and the non-bound-ary effect parameter is linearly decreases with the d10 ,d30 and d60 .
