Cohesion
From Geotechdata.info |
Updated April 29, 2011 |
| The cohesion is a term used in describing the shear strength
soils. Its definition is mainly derived from the Mohr-Coulomb failure
criterion and it is used to describe the non-frictional part of the shear
resitance which is independent of the normal stress. In the stress plane of
Shear stress-effective normal stress, the soil cohesion is the intercept on
the shear axis of the Mohr-Coulomb shear resistance line. |
