Abstract

Correct determination of strength properties is always relevant for the prediction of soil mechanical behavior. This issue in a static formulation of the problem is widely discussed in technical literature. However, the determination of strength properties under dynamic loading remains debatable. This paper discusses a new methodological approach developed to determine the parameters of dynamic shear strength of saturated samples of model clay soils based on a combined analysis of static and dynamic triaxial testing data. It is demonstrated that, other conditions being equal, the value of the angle of internal friction of clay soil samples with predominantly a coagulative structure is the same under static and dynamic conditions; however, cohesion decreases under dynamic loading and this effect is attributed to the thixotropic strength loss in such a soil.

Keywords
