A gravity retaining wall is shown in Figure (1). Calculate the factor of safety with respect to overturning and sliding, by using: 1- The Rankine active earth pressure in your calculation. (10 marks) 2- The Coulomb's active earth pressure in your calculation and letting 8' = 2/3 61. Given the following data: (10 marks) Wall dimensions: H = 6 m, x₁ = 0.6 m, x₂ = 2 m, x3 = 2 m, x₁ = 0.5 m. x3 = 0.75 m, x=0.8 m, D = 1.5 m Soil properties: Y₁ = 16.5 kN/m², b = 32°. y₂ = 18 kN/m², = 22°, c = 40 kN/m² Figure (1)
