List-I

A. Floating piles
B. Micro Piles
C. Combined footing
D. Under-reamed piles

List-II

Codes :

A B C D

• A. 2 1 4 3
• B. 2 4 1 3
• C. 3 1 4 2
• D. 3 4 1 2

Answer 1

The correct option is D 3 4 1 2

The pile resisting load by skin friction only is called floating pile.

The swelling pressure expansive soils like black cotton soils can be resisted by under-reamed pile. Micro pile resists the vertical load largely by end bearing resistance. Therefore they will be suitable in loose sands.
