＜要　旨＞

This paper presents the effect of shear rates on residual strength of four typical clay soils having high to low plasticity in its soil natures. The shear rates were fixed in a range of 0.073–0.586 mm/min. A series of tests were performed by means of ring shear apparatus. The effect of shear rates on residual strength of the high plasticity soils, medium plasticity soils and low plasticity soils were compared. The results showed that hardly increases in the strength from the residual-state of shear after the shear rate of 0.233 mm/min.
