Compression constant
When plotting the effective vertical stress against the vertical strain in the semi-logarithmic scale we often arrive at a linear dependency.
Detemination of compression constant C
Slope of this curve is one of the soil parameters particularly in case of one-dimensional deformation and is referred to as the compression constant C:
| where: | σ1ef | - | initial effective stress of soil in oedometer |
| σ2ef | - | final effective stress of soil in oedometer |
Margins of compression constant C (J.Šimek: Mechanika zemin)
| Soil |
Compression constant
C [-] |
| Loess silt | 15 – 45 |
| Clay | 30 – 120 |
| Silts | 60 – 150 |
| Medium dense and dense sands | 150 – 200 |
| Sand with gravel | > 250 |
