AbstractWhen clean sand is mixed with some amount of fines, its shear behavior can be altered significantly. Current views on the effect of fines are very diverse: several experimental studies showed that the addition of fines can reduce the collapsibility of sand under undrained conditions, whereas several others obtained an opposite conclusion. The diverse or even contradictory views in the literature indicate that the influence of fines remains an area of great difficulty. In this paper, the shear behavior of sand with the addition of fines is studied by using the 3D discrete element method (DEM), with the aim to investigate the role of fines at the grain scale so as to develop a deeper understanding. Particular effort is made to examine the applicability of the equivalent inter-granular void ratio which has been increasingly used to describe the packing state in characterizing the shear behavior of silty sands.
