Abstract:
This presentation builds upon basic information regarding helical piles and anchors. Participants will learn common helical anchor system terminology along with design and installation considerations for helical anchors and tiebacks. The application of helical tiebacks for earth retention projects will be considered with attention given to tieback design, performance, orientation, wall facing requirements and anchor testing procedures. The use of helical anchors for large moment and lateral loading is discussed and case studies for each loading condition are presented. Case studies are also used to show the application of helical tiebacks for earth retention.
