Abstract

With three different particle sizes of quartz sand as a part of fill material, direct shear tests, cyclic shear tests and post-cyclic direct shear tests were performed using a large-scale direct shear device under different thicknesses of sand. The results indicate that, in the direct shear and post-cyclic direct tests, peak shear stress of the interface reach a maximum value with the optimal thickness of thin sand layer under different particle sizes. The optimal thickness of thin sand layer interface increases with the increase of particle. In the cyclic shear tests, the maximum shear stress of interface also show a trend from increase to decrease with the increase of sand particle size. The peak shear stress of interface increases and the volume change decreases in the post-cyclic direct shear tests as compared to the direct shear tests.

Key words： direct shear test; reinforced soil interface; stress history; particle size
