Constant Rate of Strain (CRS) consolidation is a rapid test method used for determination of compressibility of clayey soils. In a CRS test, the appropriate strain rate is selected based on pore water pressure ratio, i.e. the ratio of pore pressure to total stress. In the present study, to investigate the effect of strain rate on variation of relative pore water pressure, four different clay samples of different plasticity were tested in CRS apparatus. The results of the experiments showed that the trend of variation of pore water pressure is dependent on the drained water flow regime which may be either Darcy or non-Darcy. The results also indicated that the plasticity of the clay has no considerable effect on the variation of the pore water pressure.
