v1.01.146 ZZZZ146 - Computer validation of LEM methods in the macro command CALC_STAB_PENTE#
Summary:
The objective of this test is to validate the computer functionalities for the stability analysis of slopes by methods based on the equilibrium limit theory (LEM) of macro-control CALC_STAB_PENTE.
In this test case, the stability of a homogeneous slope is analyzed by considering the infiltration of water into the ground.
**This test case does not make physical sense or solution scientific reference. **
- Modeling A: Calculation of the safety factor according to the Drucker-Prager criterion
by the Bishop method. This modeling validates the following functionalities:
Calculation of the safety factor using the simplified Bishop method.
Recovery of shear strength properties from the Drucker-Prager law of behavior.
