v1.01.135 ZZZZ135 - Computer validation of SRM methods in the macro command CALC_STAB_PENTE

Summary:

The objective of this test is to validate the computer functionalities of the macro command CALC_STAB_PENTE.

In this test case we study the stability of an embankment dam with water infiltration. This test is a non-regression test to validate the use of the macro command, and therefore has no physical meaning or scientific reference solution.

There are 2 models proposed for this test case:

• Modeling A: Calculation of the safety factor of the upstream slope with the Mohr-Coulomb law.

  This modeling validates the following functionalities:

  • The use of command variables in the input field.

  • The verification of the law of behavior in zone SRM.

  • The use of the Mohr-Coulomb law in algorithm SRM.

  • The GROUP_MA keyword allowing the definition of zone SRM by the independent mesh groups.

  • The CHAM_DEFO keyword to visualize the sliding surface.

  • The METHODE keyword = “EXPONENTIELLE”

• B Modeling: Calculation of the safety factor of the entire model with the Drucker-Prager law.

  This modeling validates the following functionalities:

  • The use of the Drucker-Prager law in algorithm SRM.

  • The METHODE keyword = “LINEAIRE”

  • The TOUT keyword = “OUI”
