Abstract
The results from a series of direct shear interface tests on a range of cohesionless soils are presented. The tests used steel interfaces with properties comparable to those of industrial piles and investigated the influence on the shearing resistance of relative density, mean particle size and stress level. These results are compared (and seen to be in good agreement) with measurements obtained using a heavily instrumented displacement pile installed in a medium dense sand. Some of the more important factors affecting the friction coefficients developed by piles in cohesionless soils are identified and their implications for design are discussed.
