As per Terzaghi, the ratio of depth of a shallow foundation to its width is
- A≤ 1Correct
- B> 10
- C> 4
- DNone of these
Solution
Concept
Terzaghi criterion
Formula
Df/B ≤ 1
Step-by-step solution
1. Terzaghi: a foundation is shallow if Df ≤ B.
Explanation
Others (Meyerhof) use Df ≤ 3–4B.
Why the other options are wrong
Larger ratios indicate deep foundations.
Shortcut
Df/B ≤ 1.
Correct answer: A) ≤ 1
