Session: Deep Foundations

ABSTRACT: The application of helical piles and anchors has expanded beyond lightly loaded and temporary structures to include medium and heavily loaded permanent structures subjected to both compression and tension. Helical piles provide an increasingly viable option in many different situations and offer benefits not available with more traditional foundation technologies. Several different instances where helical piles proved to be an effective solution to design challenges are examined and summarized.

RÉSUMÉ: Les applications pour les pieux d™acier vrillé et d™ancres ont répandu s structures temporaire à charge légère pour inclure, l™applications de structures permanente a charge moyenne ou lourde et en compression ou en tension. Les pieux d™acier vrillé son consideré de plus en plus, comme une option viable pour de nombreuses situations différentes et présente des bénéfices qui ne sont pas disponible avec la technologie traditionnelle de fondation courante. Plusieurs cas différents ou les pieux d™acier vrillé on prouve à être une solution efficace pour des design qui présente des défis, sont examiné et résumé.
