The ultimate bearing capacity of cohesionless soil depends upon

Answer: D. All of the above

The ultimate bearing capacity of cohesionless soil depends upon the size of the particles, shape of the particles, cohesive properties of the particle.

Solution

Ultimate bearing capacity of soil is defined as the maximum value of gross pressure without causing shear failure.

As per Terzaghi theory,the ultimate bearing capacity of a soil for strip footing is given by,

q_nu= CN_c+ 0.50γBN_γ+ γD_fN_q

Where,

C = Cohesion of soil

N_C, N_q, N_γ= Value of internal friction

B = Width of footing

D_f = Depth of footing

γ = Unit wt of soil

Thus as per Terzaghi theory, the Ultimate bearing capacity of soil depends on cohesive force, angle of internal friction, unit wt of soil, size and shape of particles etc.
