SUMMARY:PDCA Value Driven Webinar Series: Fundamentals of Driven Pile Design Principles
DESCRIPTION:REGISTER HERE\n\nAugust 10, 2023 | Fundamentals of Driven Pile Design Principles\n\nAaron Budge, PhD, P.E., Acting Dean, College of Science, Engineering  Technology, Minnesota State Univ.\n\nThe Minnesota Department of Transportation (MnDOT) has engaged in several performance monitoring projects to evaluate the soil-pile interaction phenomenon of drag load and down drag as new design guidance is being developed by the United States FHWA and AASHTO agencies. This presentation describes a project where a new bridge approach embankment was constructed over a soft soil layer overlying bedrock  perhaps the ideal conditions with respect to down drag development. The soils below the bridge abutment embankment experienced consolidation settlement and the bridge piling were subject to drag load. The abutment embankment was monitored for deformation performance and two steel H-piles, within the production pile group, were instrumented and subsequently monitored during construction and several years into service. Sensor response showed that the piles continued to accumulate load following construction as soils continued to consolidate. A computational model of the soil pile system was also developed to assist with the understanding of the field measurements and extrapolate performance behavior under different conditions. Lessons learned on this and related recent case-study projects relative to the down drag phenomenon are presented.
