This solution is based of the book Bodenmechanik und Grundbau, which determines the bearing capacity of the foundation soil with the following formula:
Shape factors
Depth factors
for t<b
for t>b
Inclination factors
Inclination factors of the terrain
Inclination factors of the footing bottom
where: | su | - | total cohesion of soil |
b | - | width of the foundation | |
l | - | length of the foundation | |
d | - | depth of the footing bottom | |
δ | - | angle of deviathon of the resultant force from the vertical direction | |
α | - | slope of the footing bottom | |
q | - | stress at the level of the foundation joint due to the foundation depth |
