    • Abstract
  • Soft soil has structural characteristics which affect its mechanical behavior. In this paper, triaxial rheological test was conducted for structural soft dredger fill in Tianjin Binhai new area. Through comparative analysis of undisturbed and remolded soil rheological isochronous curve we knew that the rheological isochronous curve of the structural soft dredger fill can be divided into linear visco-elastic behavior, linear visco-plastic deformation 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.
