Physical and mechanical properties of the soil and rock.
| | Soil/rock | Thickness (m) | Natural density (g/cm3) | Specific gravity | Internal friction angle (°) | Cohesion (kPa) | Modulus (MPa) | Bearing capacity (kPa) |
| | Residual soil | 3–6 | 1.7–2.1 | 2.70 | 15–20 | 12–22 | 5–8 | 150–220 | | Strongly weathered sandy shale | 4–12 | 2.4–2.5 | 2.6–2.7 | — | — | 8000–10000 | 200–400 | | Moderately weathered sandy shale | >20 | 2.5–2.6 | 2.65–2.75 | — | — | 11000–12000 | >500 |
