Research on the Dynamic Characteristics of Clay

In order to obtain the dynamic response characteristics of soil parameters, dynamic triaxial test is a commonly used method, but the project generally use the resonant column test instead. We selected a typical clay in Wuhan were carried out dynamic triaxial and resonant column test, get the relationship of the dynamic shear modulus ratio and dynamic strain under different dynamic stress and dynamic relationship with the dynamic strain damping ratio, respectively. Comparative analysis showed that the resonant column test obtained smaller results than the dynamic triaxial test.
