Experimental study on [K.sub.0] consolidation test of remolded saturated loess is carried out by GDS static triaxial apparatus. The deformation characteristics of specimens, under different loading rates, are discussed and the test results are compared and analyzed. The results show that the changing trend of the curve modeling the relation between the axial stress and the axial strain of the sample is consistent even with the change in loading rates. Thus, under this same context, the larger the loading rate is, the greater the axial strain will be, when the axial stress reaches the same value. Moreover, under different loading rates, the trend of the relationship curve between the lateral pressure coefficient [K.sub.0] and the axial strain of the soil sample is basically consistent. The stability value of the lateral pressure coefficient [K.sub.0] of the sample varies with the loading rate, but only within a fixed range.
