Rao, SM and Kamoji, AK (1998) Effect of strength - Matric suction variations on stability of a natural slope. In: International Symposium on Problematic Soils (IS-TOHOKU'98), Oct 28-30, 1998, Sendai, Japan.Full text not available from this repository.
Stability analysis of residual soil slopes are now increasingly being performed with the incorporation of the matric suction component of strength. The matric suction (u(a)-u(w)) component of shear strength is known as apparent cohesion. The relation between matric suction and apparent cohesion (c(app)) may be linear or non-linear. The impact of type of apparent strength versus matric suction relationship on the stability of an unsaturated residual soil slope is examined in this study. Results of the study showed that the factor of safety values were unaffected by the nature of the strength versus matric suction relationship for the residual soil slope examined. This was so as contribution from the effective stress- strength component to the factor of safety predominated over the contribution made by the apparent strength component.
