What will be the ratio of ultimate bearing capacity of a square footing to circular footing resting on a cohesionless soil if the diameter of the circular footing is 1.5 times the size of the square footing?

A 3 m thick clay ever is subjected to pressure 50 kN/m². If the clay layer has double drainage and undergo 50% consolidation in one year, then the settlement of clay layer one year is:

[ Take Y_w = 10 kN/m³, coefficient of permeability = 0.010 m²/year]

The discharge velocity of a soil sample is 3.89 × 10^-3 cm/sec. If the specific gravity and saturated unit weight of the soil sample is 2.63 and 19.45 kN/m³ respectively, the seepage velocity through that soil would be

A dry soil is acted upon by a tension force of 0.2 N/m. The effective size of soil grains can be taken as 0.11 mm. What will be the maximum rise attained due to capillary? Take .

Find the ultimate bearing capacity of a continuous footing having width 1.45 m and depth 1.2 m in a soil (c = 26 kN/m², ϕ = 38˚, γ = 19.25 kN/m³) as per Terzaghi’s theory. Use N_c = 81.7, N_q = 65.4 and N_γ = 75 .45
