In this reply to the discussion of the paper, the author expresses the opinion that the use of residual shear strength in stability analysis is subject to question. Slickensides were noticed in samples; their directions vary and many of them are discontinuous. Thus it is unlikely that the shear strength is initially equal to the residual shear strength. The mechanisms that could contribute to the difference between the shear strength measured in laboratory tests and that computed from the failure, include progressive failure due to strain softening, rate of loading, and defects. In the present case, the slickensides would constitute the defects and represent only one of several possible sources of inaccuracy.
