Question

The Terzaghi’s general bearing capacity equation is represented as ___________

(a) qf = 5.7 c + σ̅

(b) qf = c Nc + σ̅. Nq + 0.5γBNγ

(c) qf = c Nc + σ̅. Nq

(d) qf = c Nc

This question was posed to me during an interview.

This question is from Terzaghi’s Analysis in division Bearing Capacity of Geotechnical Engineering II

Answer 1

The correct answer is (b) qf = c Nc + σ̅. Nq + 0.5γBNγ

To elaborate: “qf = c Nc + σ̅. Nq + 0.5γBNγ” is known as Terzaghi’s general bearing capacity equation for a continuous footing.
