About the research

Abstract: The main objective of this research project is to develop a numerical modeling based on finite element method that provides an insight into the complex pier-soil interactions and the stress distribution underneath footings supported by rammed aggregate piers. Material properties and model parameters used in the analysis are derived from various in-situ and laboratory tests. The performance of the model is verified by comparing the analytical results with the actual data collected from in-situ load tests conducted at a site in southern Iowa.
