Experimental Studies of Cohesionless Subsoil Dilatancy Under Conditions of Triaxial Compression

Based on the results of triaxial tests for sands of various particle-size distribution, a statistical assessment of the dependence of Reynolds dilatancy on the parameters of density and stress state was carried out. An improved model, which takes into account the dependence of the dilatancy angle on the current and residual void ratios and the effective stress level, is proposed. Recommendations are given on the use of research results in the practice of geotechnical calculations.
