SPT-based Methods for Estimating Installation Torque and Capacity of Helical Piles

Helical piles are extensively used across Canada in various engineering applications. Current design methods estimate the axial capacity of helical piles using soil strength parameters when site investigation is available. Alternatively, helical piles can be designed from an empirical torque correlation when installation torques are available. However, it will be more valuable to the industry […]
