Question: A braced cut is carried out to 10 m depth at a site where the soil consists of 4 m of sand ( = 17.0

A braced cut is carried out to 10 m depth at a site where the soil consists of 4 m of sand (γ = 17.0 kN/m³, ϕ' = 33°) at the top underlain by 6 m of clay (γ = 18.5 kN/m³, c = 35 kN/m²).

a. What would be the average value of cohesion and the unit weight for the equivalent homogeneous soil profile?

b. Show the lateral earth pressure envelope you would use in determining the strut loads.
