Expert Solution
Step 1: Expressing active earth pressure

The expression for active earth pressure, say pa at any depth z for a cohesive back-fill can be written as:

pa,z = ka(q+γz)-2cka

here,

ka : Coefficient of active earth pressure

q : surcharge acting on top of the back-fill

γ : unit weight of the soil

c : cohesion
