ICC-ES Evaluation Report
Hannele Zubeck and He Liu, “Evaluation of Helical Piers for Use in Frozen Ground”, Proceeding of the 10th International Conference on Cold Regions Engineering, The Mountain Club on Loon Lincoln, New Hampshire, April 2002.
The helical piers have been used in remote villages by hundreds for foundations for utilidors and boardwalks. However, their use could be increased if engineers would have confidence specifying them in their projects. They feel that neither design guidelines nor recorded performance data exist for helical piers. Therefore, Alaska Science and Technology Foundation (ASTF) funded this research project to develop guidelines for design of helical piers in frozen ground.
