4. Practical calculations of thrust and stop coefficients
4.1 Kérisel and Absi tables
In current practice, only the tables developed by Kérisel and Absi provide reliable values for thrust and stop coefficients. It is essential to note that these tables take into account specific conditions such as the angle of ground friction and the geometric configuration of the screen.
Coulomb's classical formulas only apply to thrust calculations, while Rankine's are limited to the special case of a vertical screen, with a horizontal free surface and zero ground-screen friction.
The Kérisel and Absi tables provide thrust and stop coefficients for two main scenarios:
heavy soil (soil with its own...
