Refer to the slope in Problem 16.7. Assume that the shear strength of the soil is improved by soil stabilization methods, and the new properties are as follows: γ = 22 kN/m³, ϕ' = 32^ο, and c' = 75 kN/m². What would be the improved factor of safety against sliding along the trial failure surface AC?

Data From Problem 16.7

Figure 16.50 shows a slope with an inclination of β = 58^ο. If AC represents a trial failure plane inclined at an angle θ = 32^ο with the horizontal, determine the factor of safety against sliding for the wedge ABC. Given: H = 6 m, γ = 19 kN/m³, ϕ' = 21^ο, and c' = 38 kN/m².
