In this paper, triaxial dredger fill in Tianjin Binhai new area was studied.  Through comparative analysis of undisturbed and remolded soil rheological isochronous curve the authors knew that the rheological isochronous curve of the structural soft dredger fill can be divided into linear visco-elastic behavior, linear visco-plastic defor- mation and nonlinear visco-plastic deformation. When stress is less than structure yielding stress, rheological isochronous curve linear rigidity is larger; conversely, with the soil structure damaged, it turned to smaller, finally tended to be a certain value approaching to remolded soils. The structure affects rheological isochronous curve is mainly in linear elastic stage and smaller in plastic stage.
