Passive earth pressure – total stress

When determining the passive earth pressure in cohesive fully saturated soils, in which case the consolidation is usually prevented (undrained conditions), the horizontal normal total stress σx receives the form:

where: σx - horizontal total stress (normal)
σz - vertical normal total stress
Kuc - coefficient of earth pressure
cu - total cohesion of soil

The coefficient of earth pressure Kuc is given by:

where: Kuc - coefficient of earth pressure
cu - total cohesion of soil
au - total adhesion of soil to the structure
