Stress-Dilatancy for Soils. Part II: Experimental Validation for Triaxial Tests

Zenon Szypcio
Published Online: 2017-02-08 | DOI: https://doi.org/10.1515/sgem-2016-0031


Different forms of the stress-dilatancy relations obtained based on the frictional theory for the triaxial condition are presented. The analysed test data show that the shear resistance of many soils is purely frictional. The angle Φ0 represents the resistance of the soil as a combined effect of sliding and particle rolling on the macro-scale during shear at the critical frictional state. The stress-plastic dilatancy relations differ not only for triaxial compression and extension but also for drained and undrained conditions. The experiment investigated shows the correctness of the frictional state theory in the triaxial condition.
