Overpredicted Resistances of Non-Displacement Piles in Sands Using Static Analysis Methods
he goal of this research is to determine the cause of the overpredicted resistances of the low-displacement piles in the project-specific subsurface conditions and either recommend modification factors that can be applied to the Nordlund method or recommend another static analysis method (such as the Beta or API method) to accurately estimate pile lengths. To achieve these goals, the existing data (where the resistance of low-displacement piles in sands was overpredicted) as well as data from two new projects (where the Minnesota Department of Transportation plans to drive low-displacement piles) will be systematically analyzed in this study. Regression methods and sensitivity analyses, as well as numerical simulations, will be used to better understand the reason for the overprediction of the pile resistance, and modify the existing static analysis models to improve the pile resistance predictions in sands.
