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 pressure are given by:

where: δ - angle of friction structure - soil
α - back face inclination of the structure
