ABSTRACT: Helical piles are traditionally considered for use in applications as tension anchors for retaining wall tiebacks or shoring, and as compression piles in light to medium load situations including temporary, residential and single storey commercial structures. Helical piles are very capable of fulfilling requirements in highly loaded applications, and are commonly the most efficient option at doing so. Two different instances of high load applications in both compression and tension where helical piles fulfilled all requirements and proved to be the most efficient solution are presented.

RÉSUMÉ: Les pieux d™acier vrillé sont considérer pour les applications d™ancres en tension pour des murs de soutènement ou des murs d™étayage ainsi que pour les applications de charges légères ou moyenne en compression qui inclus des structures temporaire, a simple étage, résidentiel et commerciale. Les pieux d™acier vrillé sont capables de rencontrer les exigences pour des applications à hautes charges et sont considérer la méthode la plus efficace pour ce but. Cette rédaction présente deux cas différent pour des applications de haute charges en compression et en tension ou des pieux d™acier vrillé on rencontré les exigences du projet et on démontré a être la méthode la plus efficace.
