The value of bearing capacity factors used in Terzaghi’s equation depends upon

Which of the following are the assumptions used by Terzaghi in deriving bearing capacity equation?

(i) The base of the footing is smooth.

(ii) The load on the footing is vertical.

(iii) The length to width ratio of footing is infinite

(iv) The shear strength of soil above the base of the footing is negligible.

Match List 1 with List 2 and select the answer using the codes given below

List 1

(i) General shear failure

(ii) Local shear failure

(iii) Punching shear failure

List 2

(a) loose sand and soft clays

(b) Dense sand and stiff clay

(c) Medium dense sand

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?

The water table will not cause any effect on the bearing capacity of a footing 1.8 m wide and 1.5 m deep, if it is situated at
