For a shallow foundation, the depth to width ratio (D_f/B) is typically:
A≤ 1 (depth less than width); deeper = pile (deep foundation)
BSame
CAlways 10
D≥ 5
Answer & Solution
Correct answer: A. ≤ 1 (depth less than width); deeper = pile (deep foundation)
Foundations classified by depth: shallow (D_f/B ≤ 1) — spread footings, mat. Deep (D_f/B > 4-5) — piles, drilled shafts. Choice depends on soil bearing capacity, settlement tolerance, structural load, water table. Shallow cheaper, easier; deep needed when surface soils weak.
