Passive earth pressure - the Müller – Breslau theory

Passive earth pressure follows from the following formula:

where: Kp - coefficient of passive earth pressure
c - cohesion of soil
σz - vertical normal total stress

The coefficient of passive earth pressure Kp is given by:

where: φ - angle of internal friction of soil
δ - angle of friction structure - soil
β - slope inclination
α - back face inclination of the structure

The vertical σpv and horizontal σph  components of passive earth pressure  are given by:

where: δ - angle of friction structure - soil
α - back face inclination of the structure
