Abstract:The primary objectives of this research include: performing static and dynamic load tests on
newly instrumented test piles to better understand the set-up mechanism for individual soil
layers, verifying or recalibrating previously developed empirical set-up models for piles driven
in soft cohesive soils (prior LTRC Project 11-2GT), and developing an analytical methodology to
estimate the duration of pile set-up.
Minor objectives include: developing a model to predict spatial distribution of excess pore water
pressure due to pile driving, establishing a relationship between vertical shaft displacement
and associated shear resistance by analyzing strain gage data from instrumented test piles,
developing a method to predict the pile tip resistance at different axial tip displacements, and
calculating the total and effective stress parameters (e.g., adhesion factor).
