Reference number : GC-2017-Q4-00453, amendment number : , agreement type : G, recipient legal name : Deng, Lijun (University of Alberta), recipient country : CA, recipient province : nan, recipient city : Alberta, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : A helical pile is an innovative deep foundation type that has numerous advantages over conventional piles. As_x000D_
these advantages are realized in the foundation industry, this pile type is becoming increasingly common across_x000D_
Canada. Helical piles are now a preferred foundation solution for structures such as: low-rise commercial and_x000D_
residential buildings, power transmission towers, and modular buildings._x000D_
It is widely accepted that the soil disturbance caused by helical pile installation is less than that of_x000D_
conventional piles; however little research has been conducted to quantify this difference or to determine its_x000D_
effect on pile capacity. Due to this research gap, the short-term capacity reduction caused by installation_x000D_
disturbance is difficult to predict and is often neglected. These deficiencies may lead to improper capacity_x000D_
estimations and under-design._x000D_
Located in Leduc, Alberta, Twist Development Inc. (Twist) is a manufacturer of helical piles. It is important_x000D_
to Twist, and the helical pile industry as a whole, that the understanding of helical pile installation effects is_x000D_
further investigated. The overall objective of the proposed research is to quantify the installation induced pore_x000D_
pressure generation and its effect on the short-term capacity of helical piles. This research will lead to more_x000D_
accurate designs and greater confidence in this pile type across the foundation community., program purpose french : A helical pile is an innovative deep foundation type that has numerous advantages over conventional piles. As_x000D_
