Abstract

Abstract

A series of shear tests of interface between sandy soil and concrete face was performed by developed largescale simple shear apparatus, and the effect of different single grain sandy soil on mechanical properties of interfacewas studied. By the analysis of test results, the interface thickness and shear displacement of different single grainsandy soil were presented when the sample destroyed. It was shown that there was good linearity of shear strength andnormal stress. In the vertical stress at lower, relation curves of the shear stress and displacement showed strainsoftening; with the increase of vertical stress, the trends of relation curves of the shear stress and displacementshowed more obvious, at this time, relation curves of the shear stress and displacement of interface between differentsingle grain sandy soil and concrete face could be seen as being composed of a curve and a flat line. Lower thevertical stress dilatancy more obvious; with the increase of vertical stress, shear dilatancy weakened, and shear stresswas gradually increasing when shear dilatation appeared.
