À propos des benchmarks en géotechnique
This paper deals with the process of checking and validating commercial finite element codes in the field of geotechnics, and specially the need for validation and learning exercises. We propose, herein, some general informations about benchmark-workshops that need to be organized in order to be ensure the validity of softwares or to assess the limits of computational codes. In particular, practical and numerical modelling difficulties inherent to full scale geotechnical structures tests are examined: for example no assurance on measure, the user's choice for initial stress state, the limitation of the model, the choice of parameters for the constitutive law, etc. On the other hand, for future benchmarks, some instructions and validity criteria are proposed from various observed—calculated case histories of geotechnical structures.
