[Mesures a vérité non additive pour déterminer les densités relatives des sables utilisant les tests de pénétration du cone (tpc)]
Dans cette Note, on développe une approche utilisant les intégrales floues afin d'analyser les corrélations utilisées communément pour déterminer la densité relative D à partir de mesures obtenues dans les Tests de Pénétration Conique (TPC). Dans ces données, les mesures non-additives sont traitées comme mesures floues afin de rendre compte de la relation existant entre la compressibilité évaluée grâce au rapport entre le frottement des sables et les corrélations de base. Les résultats relevant du cas étudié montrent que les mesures floues et les intégrales floues peuvent être utilisées dans une approche nouvelle au génie géotechnique.
In this Note, a fuzzy-integral based approach is developed for aggregating some of the available correlations that are commonly used for determining relative density , from cone penetration test (CPT) data, in which non-additive measures are used as fuzzy measures to relate the actual compressibility measured by the friction ratio of sands to the base correlations. The results of the case studied show that fuzzy measures and the fuzzy integral can be utilized for a new approach in geo-technical engineering.
