Abstract
Dynamic behavior of natural and model low-cohesive soils has been studied. All these silty-sandy soils demonstrated dynamic dilatancy with the exception of dense dry specimens and tended to liquefy if the degree of saturation Sr > 0.9. Beginning from the clay content about 1.5% by weight thixotropic hardening of low-cohesive soils can be registered and the relationship of this hardening versus normalized specific surface of the soils, calculated from BET equation, can be represented by a smooth S-shaped curve with three distinct parts characteristic for dilatant (cohesionless), dilatantly-thixotropic (low-cohesive) and quasi-thixotropic (cohesive) soils.
