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 | - | ||
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 | - | |
α | - | back face inclination of the structure |
