The ultimate bearing capacity of cohesionless soil depends upon-

  1. Size of the particles
  2. Shape of the particles
  3. Cohesive properties of the particle
  4. All of the above

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,

qnu= CNc+ 0.50γBNγ+ γDfNq

Where,

C = Cohesion of soil

NC, Nq, Nγ= Value of internal friction

B = Width of footing

Df = 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.
