Stress-Dilatancy of Unsaturated Soil
Dilatancy significantly influences the shear strength of soils, which is of paramount importance for geotechnical engineers, which is commonly measured in the form of dilatancy angle. Only a very limited number of studies have examined the factors influencing dilatancy of unsaturated soils. In this research, the results from a series of suction-controlled triaxial tests following conventional triaxial compression (CTC) stress paths at different suction levels and net confining pressures were utilized to study the variation of dilation angle of compacted silty soil specimens with matric suction and net confining pressure. It was also observed that for all selected approaches, an increase in matric suction resulted in an increase in peak dilation angle. An increase in net confining pressure resulted in a decrease in dilation angle. These experimental findings would aid in calibrating advanced constitutive models capable of accurately incorporating the effect of various stress states on the dilatancy angle.
