Bowles Theory
The Bowles solution allows incorporating the influence of the cohesion on the root bearing capacity - therefore it is more suitable for cohesive soils.
where: | d | - | root diameter |
l | - | root length | |
Ko | - | coefficient of pressure at rest | |
σz | - | average geostatic stress at the micropile root | |
φ | - | average magnitude of the angle of internal friction at the micropile root |
