Determination of the carrying capacity of ground anchors with the correlation and regression analysis
Calcul de la force portante des tirants d’ancrage à l’aide de l’analyse de la corrélation et de la régression
Dr.-Ing., Technical University of Hannover, Germany
In the last decade a great number of fundamental and suitability tests of ground anchors have been performed in Hannover, GRF. These tests have been supervised by the « Institut für Grundbau und Bodenmechanik, Technische Universität Hannover », which also performed the laboratory soil investigations . This contribution describes the evaluation of the gathered observations by application of statistical methods. The result of these investigations is the proposal of two equations to estimate the carrying capacity of ground anchors. one for anchors in non-cohesive soil and the other for anchors in cohesive soil.
Résumé
Au cours de la dernière décennie, on a effectué un grand nombre d’essais de tirants d'ancrage à Hannovre (Allemagne Fédérale). La communication décrit l'interprétation des observations recueillies par application des méthodes statistiques et propose deux équations pour la capacité portante des tirants d'ancrage : l'une pour les sols pulvérulents et l'autre pour les sols cohérents.
