Experimental investigation of the deformability of optimal mixtures of alluvial soils under high pressure
As a result of investigations, an experimental method was developed for determining the characteristics of deformability of mixtures of alluvial soils (relative settlement, coefficient of compressibility, and modulus of deformation) on the basis of their granulometric composition expressed by the uniformity coefficient.
Large-scale experiments showed that with an increase in the uniformity coefficient the compressibility and crushability of soil decreases considerably, and this makes it possible to change promptly and effectively the properties of the materials, bringing them closer to the optimal or required.
The empirical relations for determining the deformation characteristics, expressed only by two parameters (νo and σz), are clear and simple.
