Pile Setup in Glacial Soils of Northern Missouri
Publication: Geo-Congress 2024
ABSTRACT
Pile resistance during and immediately after driving in cohesive soils is often significantly lower than the eventual resistance that develops in the long term. This time-dependent increase in resistance, commonly called pile setup, can lead to large differences between dynamic estimates of geotechnical pile resistance at the end of pile driving (EOD) and the actual pile resistance after setup has occurred. In this study, data from 28 dynamic pile load tests performed at nine bridge sites in northern Missouri were compiled and analyzed to characterize and better understand the setup characteristics. Setup was observed in 27 of the 28 piles. The average setup factor at times greater than 60 h for piles driven in clay profiles was 1.75 with a standard deviation of 0.3, while setup factors for piles driven in mixed soil conditions were more variable with a standard deviation of 0.45 and a slightly higher average setup of 1.86. The setup in clay profiles is shown to correlate well with average pocket penetrometer strength values.
