Abstract

Continuous flight auger piling in sand can cause disturbance of the surrounding soil if the auger is allowed to rotate without vertical penetration. The results of an experimental programme are presented which show that the degree of disturbance depends on the initial density of the sand and the auger geometry as well as the number of over-rotations. An analysis of the auger transportation action in sand is presented which considers the sand particle motions within the flights. Forage à la tarière pour la construction des pieux CFA en milieu sableux peut perturber le sol environnant si la pénétration de la tarière tournant n’est pas verticale. Les résultats d’un programme experimental sont présentés ici et montrent que le degné de perturbation depend de la densité initiale du sable et de la géométrie de la tarière, assi bien que du nombre de sur-rotations. Une analyse de l’action de transport forage de la tarière dans le sable est présentée, et considère les mouvements des particules de sable.
