In order to investigate the rheological properties of Lianyungang soft marine clay
a triaxial rheological test is performed. Based on the analysis of laboratory tests
Lianyungang soft marine clay can be regarded as an elastic-viscoplasticity. Then
the generalized Bingham model and the ellipse-parabola two-yield-surface model are combined to develop a new rheological model to describe its rheological behavior. Finally
all the parameters are obtained and the applicability of this model is validated.
