BPSC AE CE_QUIZ-3

A square footing (1.2 × 1.2 m) is placed in a soil (c = 28.6 kN/m², ϕ = 35˚, γ = 18.65 kN/m³) up to a depth of 0.95m. If the square footing is to be replaced by the circular footing, determine the diameter of footing required for the same bearing capacity. Assume general shear failure and take N_c = 57.8, N_q = 41 .4 and N_γ = 42 .4

Determine the ultimate bearing capacity of a square footing of size 1.56 m in a cohesive clay having undrained cohesion value 18.76 kN/m², unit weight 19.45 kN/m³ and the depth of the footing is 1.2 m using Skempton’s method.

When a plate load test was conducted by putting a 60 cm square plate on top of sandy deposit, the ultimate bearing capacity was observed as 60 KN/m². What is the ultimate bearing capacity for a strip footing of 1.2 m width to be placed on the surface of same soil?

Permissible settlement is relatively higher for which of the following?

According to IS code, the total settlement of isolated footings for cohesive soil should be
