The values of N c, N q and N γ as given by Terzaghi are shown in Table 18.1. Assumptions in Terzaghi’s Theory of Bearing Capacity: N γ = 2 ( N q + 1) tan ⁡ ϕ ′ 1 + 0.4 sin ⁡ 4 ϕ ′ {\displaystyle N_ {\gamma }= {\frac {2\left (N_ {q}+1\right)\tan \phi '} {1+0.4\sin 4\phi '}}} For foundations that exhibit the local shear failure mode in soils, Terzaghi suggested the following modifications to the previous equations. The equations are given below. The Buisman–Terzaghi equation is used in either of two derivative forms, which depend upon the soil type and rate of loading.

Solution: From Table 1 or Figure 1, Nc = 5.7, Nq = 1.0, Nr = 0 for φ = 0 degree Determine ultimate soil bearing capacity using Terzaghi’s bearing capacity equation for square footing Qu = 1.3 c Nc + γ D Nq + 0.4 γ B Nγ = 1.3*1000*5.7 +120*2*1+ 0 N γ = 2 ( N q + 1 ) tan ⁡ ϕ ′ 1 + 0.4 sin ⁡ 4 ϕ ′ {\displaystyle N_ {\gamma }= {\frac {2\left (N_ {q}+1\right)\tan \phi '} {1+0.4\sin 4\phi '}}} For foundations that exhibit the local shear failure mode in soils, Terzaghi suggested the following modifications to the previous equations. The equations are given below. The bearing capacity factors, Nc, Nq, N g, are function of internal friction angle, f. Terzaghi's Bearing capacity equations: Strip footings: Qu = c N c + g D N q + 0.5 g B N g. Square footings: Qu = 1.3 c N c + g D N q + 0.4 g B N g.

The angle α=ϕ (according Terzaghi theory in the last figure “above”) was replaced by α=45+ ® 6. So, the bearing capacity factor will be change. The variations of bearing capacity factors (N a,N o,N ) and underlying soil friction angle (ϕ) are given in (Table 3.3, P.144). Shape Factors: F a q=1+ l B L p l N o N a p F o q=1+ l B L ptanϕ
