Abstract
A numerical procedure to determine the location of the critical noncircular slip surface giving the minimum factor of safety is presented taking into account the effect of strength anisotropy of the soil in slopes. Comparisons are made with the critical noncircular slip surface in the soil slope with isotropic strength. Several case studies prove the strength anisotropy does not greatly influence on the location of the critical slip surface, but considerably affects the value of safety factor.
