Question

Consider the following statements:

1. The bearing capacity of soil-foundation system on a purely cohesive soil is independent of foundation dimension.

2. The contact pressure distribution under a rigid footing on a cohesive soil is uniform.

Which of the above statement(s) is/are incorrect ?

• A. 1 only
• B. 2 only
• C. 1 and 2
• D. None

Answer 1

The correct option is B 2 only

The contact pressure distribution under a rigid footing is maximum at edges and minimum at centre.

Since for cohesive soil $(\varphi =0),N_{\gamma }=0,$ hence bearing capacity is independent of footing size
