A Rheological Study Of Cohesive Soils, David L. Allen
Kentucky Transportation Center Research Report
An attempt has been made to describe the mechanistic behavior of remolded and undisturbed soils by application of the principles of rheology. This was accomplished by approximating and comparing the data obtained from transient creep tests and relaxation tests to the mathematical behavior of mechanical impedance models. The data were also analyzed by transforming static moduli and compliances into dynamic values by the application of Fourier transforms. Distribution functions of relaxation and retardation times, obtained by the application of LaPlace transforms, are presented.
All soils tested exhibited similar dynamic moduli and complince curves indicating that soil type had little effect …
