Standard analysis
The bearing capacity of foundation soil composed of rocks or weak rocks is found from the expression proposed by Xiao-Li Yang and Jian-Hua Yin1:
where:
| where: | s | - | nonlinear parameter depending on rock properties (according to Hoek and Brown) |
| GSI | - | Geological Strength Index | |
| D | - | coefficient reflecting damage of a rock mass | |
| Ns,Nq,Nγ | - | coefficients of bearing capacity depending on the angle of internal friction | |
| Ns | - | coefficient of strength of a rock depending on GSI and strength parameter mi | |
| φ | - | angle of internal friction of rock | |
| σc | - | uniaxial compressive strength of rock > 0,5 MPa | |
| q0 | - | equivalent uniform loading accounting for the influence of foundation depth | |
| γ2 | - | unit weight of soil above the footing bottom | |
| b | - | width of foundation |
