“…In other cases such a slope with a height of 25 and face angle of 56.3 • shown in figure 8(d), the critical slip surface in anisotropic condition is located in closely deeper situation relative to isotropic slip. The conformity of the critical slip surface location in anisotropic cohesive slopes was previously observed by Arai & Nakagawa (1986) and Al-Karni & Al-Shamrani (2000).…”

This paper aims to investigate the effect of anisotropy of shear strength parameter on the stability of a sandy slope by performing the limit equilibrium analysis. Because of scarcity of mathematical equation for anisotropic friction angle of sand, at first, all results of principal stress rotation tests are processed by artificial neural network and a computational procedure is developed for determining sand friction angle subjected to various loading directions. By implementing this procedure, slope stability analysis is performed in both isotropic and anisotropic conditions. The results indicate that while isotropic slope stability overestimates the factor of safety between 5 and 25% which the deviation is more for flatter slope, the location of critical slip surface is coincident in both conditions. Also in specific slip surface, the parameters of face angle, geometry of slip surface and soil properties relating to anisotropy are the main factors governing the result of anisotropic slope stability.

“…They found that the anisotropy is more effective in soils with lower friction angle. (Arai & Nakagawa 1986) found that anisotropy of shear strength does not greatly influence the location of critical slip surface. (Su & Liao 1999) proposed the chart for the ratio of anisotropic safety factor to isotropic state in cohesive slopes.…”

“…For this fact, the strength of natural soils shows anisotropy more or less [1][2][3][4]. And it has been found by many researchers that there is an obvious effect of strength anisotropy of soils on the stability of soil slopes [5][6][7][8]. In addition, it has been shown by most of previous studies that strength anisotropy does not make that significant influence on the location of critical sliding surface as that on the safety factor.…”

The effect of anisotropy of friction angle in natural deposited soil on the stability of soil slopes was studied in this paper. Stability analysis was performed on a uniform soil slope with anisotropic friction angle. Spencer’s method was used, and the variation of friction angle was assumed to be linear to the change of direction of the slip surface. It was shown that 7-10 percent of change in safety factor might achieve within a 10m-highed anisotropic soil slope. It was also found from the analysis that that frictional anisotropy had no obvious effect on the location of critical slip surface.
