Cantilever Wall
Earth pressure at rest for inclined ground surface at the back of structure
For inclined ground surface behind the structure (0°< β ≤ φ) the earth pressure at rest assumes the form:
| where: | φ | - | angle of internal friction of soil |
| β | - | slope inclination | |
| σz | - | vertical geostatic stress | |
| Kr | - | coefficient of earth pressure at rest |
For inclined back of wall the values of earth pressure at rest are derived from:
| where: | α | - | back face inclination of the structure |
| σz | - | vertical geostatic stress | |
| Kr | - | coefficient of earth pressure at rest |
Normal and tangential components are given by:
| where: | α | - | back face inclination of the structure |
| σz | - | vertical geostatic stress | |
| Kr | - | coefficient of earth pressure at rest |
The deviation angle from the normal line to the wall δ reads:
| where: | α | - | back face inclination of the structure |
| Kr | - | coefficient of earth pressure at rest |
