To determine residual strengths of a kaolin and a landslide clay, reversal box shear tests were carried out. In this paper the normal stress, the shear displacement rate, the overconsolidation ratio, and the disturbance and the grading of the soil samples are taken up among many factors affecting test results. Consequently, residual strength of kaolin is not significantly influenced by the normal stress above 200 kPa, the overconsolidation ratio and the shear displacement rate below 1.0 mm/min. Also, there exists no difference between residual strengths of undisturbed and disturbed samples. Furthermore, residual strength of disturbed samples passed through 0.42 mm and 0.85 mm sieves respectively, was much lower than that of sample having an original grading.
