Session: Infrastructure

ABSTRACT: The soil response around a high temperature pipeline proposed for construction in northern Alberta was evaluated. A medium-scale laboratory model testing program was used to gain a better understanding of the thresholds at which silty sandy backfill infilled around a pipeline when subjected to cyclic upward loading. Soil movement fields were identified. Various mitigation techniques were evaluated in order to both delay and reduce the net downward soil movement from pipe displacement cycles.

RÉSUMÉ: La réponse du sol entourant un pipeline à haute température qui est proposé pour construction au nord de l™Alberta a été évaluée. Un programme de tests de laboratoire à moyenne échelle a été effectué afin de mieux comprendre les limites pour lesquelles le remblai limoneux sablonneux se dépose autour du pipeline lorsque ce dernier est soumis à un chargement cyclique vertical et dirigé vers le haut. Les champs de mouvements du sol on été identifiés. Plusieurs mesures de mitigation ont été évaluées dans le but de retarder et de réduire le mouvement vertical net du sol dirigé vers le bas causé par les déplacements cycliques de la conduite.
