A 2 m wide continuous foundation is to be placed in a saturated clay at 1.5 m

Question:

A 2 m wide continuous foundation is to be placed in a saturated clay at 1.5 m depth where c_u = 40 kN/m² and γ = 18.0 kN/m³.

a. What is the ultimate bearing capacity of the foundation?

b. To increase the ultimate bearing capacity, it is proposed to place dense sand (ϕ' = 42° and γ = 18.5 kN/m³) in a trench directly beneath the foundation to a depth of 4.0 m.

The width of the trench is the same as the width of the foundation. What is the new ultimate bearing capacity of the foundation?
