Abstract
This study deals with described the experimental results concerning rheology characteristics of the liquefied sand specimen which was measured by a viscometer using tuning-folk vibration mechanism. The specimen was kept in the liquefied sand condition by upward infiltration flow during measurements, and the behaviors of flow curves measured were changed by flow rate from pseudo-plastic fluid like to Newton fluid like as the flow rate increased. Furthermore, the behaviors which could be considered Newton fluid or Bingham fluid were shown as we focused on the shear strain rate area less than 0.2 (1/s). As a conclusion, it became clear that the coefficients of viscosity in these results depended on the shear strain rate, namely the flow curves had the characteristics of pseudo-plastic fluid. From these results, the equation to obtain the coefficient of viscosity which was dependent on shear strain rate and flow rate as pseudo-plastic fluid was derived.
