The conditions listed below apply to an embankment slope. Compare the factor of safety for slope stability determined when using the Barnes toe circle factors and when using the Spencer slope stability curves.

• Slope height = 62 ft.

• Slope inclination horizontal to 1 vertical.

• Soil unit weight = 112 pcf.

• Soil cohesion, c¿ = 700 psf.

• Angle of internal friction = 20°.

• Pore pressure condition, r_u
= 0.25.
