This paper reports an experimental study concerning the frictional behaviour of sand-solid structure interfaces. The study was performed using a constant normal stiffness (CNS ) direct shear box. Three natural silica sands and four aluminium plates with different roughnesses were investigated. A comparison between constant normal load (CNL) and CNS tests is reported. The influence of the main factors controlling the frictional behaviour of the investigated materials such as: constant normal stiffness, roughness of solid surface, sand properties and relative density, initial effective normal stress are analysed and discussed.

Abstract

This paper reports an experimental study concerning the frictional behaviour of sand-solid structure interfaces. The study was performed using a constant normal stiffness (CNS ) direct shear box. Three natural silica sands and four aluminium plates with different roughnesses were investigated. A comparison between constant normal load (CNL) and CNS tests is reported. The influence of the main factors controlling the frictional behaviour of the investigated materials such as: constant normal stiffness, roughness of solid surface, sand properties and relative density, initial effective normal stress are analysed and discussed.
