This study aimed to develope a new stability analysis method considering displacement rate monitored in a landslide slope. This paper describes influences of shear displacement rate on residual strength of clays, based on results of ring shear test. The shear displacement rate adopted in the tests were changed in range from 0.02 to 2.0 mm/min. Soil samples tested were Kaolin, Shimajiri mudstone and 2 clays of Yuya landslide. Main conclusions are as follows. Firstly, the internal friction angle at residual increases linearly with increasing the shear displacement rate in logarithmic scale. Secondly, the stress ratio at residual changes with the accompanying change in shear displacement rate.
