EK499
Overconsolidation ratio (OCR) is the ratio by which the current vertical effective stress in the soil was exceeded in the past.
EK491
Downward seepage increases the resultant effective stress; upward seepage decreases the resultant effective stress.
EK489
The effective stress in a saturated represents the average stress carried by the soil solids and is the difference between the total stress and the porewater pressure.
EK487
Soils cannot sustain tension. Consequently, the effective stress cannot be less than zero.
EK486
The effective stress is the average stress on a plane through the soil mass.
EK477
Effective stress is the stress carried by the soil particles.
