Table 3 Mechanical properties of concrete and soil models.
From: Investigation of acoustic waves behavior of an underground tunnel in a multilayer soil
Concrete type | Density (kg/m3) | Module of elasticity (GPa) | Poisson's ratio |
|---|---|---|---|
Concrete I | 2800 | 37 | 0.2 |
Concrete II | 2700 | 35 | 0.2 |
Concrete III | 2400 | 28 | 0.2 |
Soil | 2200 | 8.23 | 0.3 |
