High-frequency vibration impacts on water-saturated dispersed soils lead to the development of vibrocreep deformations. The magnitude of these deformations can be obtained from the results of dynamic triaxial tests. The paper presents the results of laboratory tests of clay soil samples of soft-plastic and fluid-plastic consistency. As a result of the tests, the rheological strengthening parameter and the dynamic viscosity of the soil were obtained. The laboratory test was simulated in a numerical formulation to clarify the dependence of dynamic viscosity on dynamic stresses. In the course of numerical experiments, the dependences of dynamic viscosity on dynamic stresses were obtained for clay soils of various consistency (soft-plastic, fluid-plastic and fluid consistency). Derived curves of vibrocreep based on Barkan’s theory of vibrocreep were obtained. Also, the actual wave propagation velocities for weak clay soils were obtained, which are necessary to determine the magnitude of the dynamic stresses that occur in the soil base. A number of numerical experiments on dynamic triaxial compression were performed to determine the dependence of dynamic viscosity on the magnitude of static and dynamic stresses for sandy soils.
