Passive Earth Pressure - The Absi 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 program takes values of the coefficient Kp from a database, built upon the tabulated values published in the book: Kérisel, Absi: Active and passive earth Pressure Tables, 3rd Ed. A.A. Balkema, 1990 ISBN 90 6191886 3.
The vertical σpv and horizontal σph components of passive earth pressureare given by:
where: | δ | - | |
α | - | back face inclination of the structure |
