Passive Earth Pressure - SP 22.13330.2016
Passive earth pressure follows from the following formula:
where: | σz | - | vertical geostatic stress |
c | - | cohesion of soil | |
Kp | - | coefficient of passive earth pressure |
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 |
Horizontal and vertical components of the passive earth pressure become:
where: | σp | - | passive earth pressure |
δ | - | ||
α | - | back face inclination of the structure |
