Which of the following statements are true?
A. The proportioning of footing in sand is more often governed by settlement rather than by bearing capacity.
B. The pressure bulb profiles under a strip footing form as co-axially imaginable bulbs under its length.
C. Friction piles are also called as 'floating piles'.
Choose the most appropriate answer from the options given below:

Question

Match LIST-I with LIST-II:\[\begin{array}{|c|l|l|} \hline \textbf{LIST-I (Type of footing/foundation)} & & \textbf{LIST-II (Suitability)} \\ \hline \text{A. Spread footings} & & \text{II. Up to 3 m black cotton soil followed by medium dense sand} \\ \hline \text{B. Friction piles} & & \text{IV. Loose sand extending to great depth} \\ \hline \text{C. Raft foundation} & & \text{I. Soft clay for 10 m followed by hard rock stratum} \\ \hline \text{D. End bearing piles} & & \text{III. Compact sand deposit extending to great depth} \\ \hline \end{array}\] Choose the most appropriate match from the options given below:

Answer 1

Step 1: Evaluate each assertion.
- (A) Correct: In sandy soils, the design is typically controlled by settlement, not ultimate bearing capacity.
- (B) Correct: Pressure bulbs beneath strip footings are elongated and can be visualized as co-axial bulbs extending along their length.
- (C) Correct: Friction piles transmit load via skin friction, thus are termed 'floating piles'.

Step 2: Final Determination.
All three statements are accurate, indicating that the correct option is (1).
