RCC Structures Design
If A is the area of the foundation of a retaining wall carrying a load W and retaining earth of weight 'w' per unit volume, the minimum depth (h) of the foundation from the free surface of the earth, is

h = (W/Aw) [(1 + sin φ)/(1 + sin φ)]
h = √(W/Aw) [(1 - sin φ)/(1 + sin φ)]²
h = (W/Aw) [(1 - sin φ)/(1 + sin φ)]²
h = (W/Aw) [(1 - sin φ)/(1 + sin φ)]
