Part of: Settlement of Shallow Foundations on Cohesionless Soils: Design and Performance


The foundation design for the Intermountain Generating Station was based on comprehensive geotechnical investigations that included cone penetrometer tests, borings, pressuremeter tests, seismic velocity surveys, as well as conventional and special laboratory tests. Settlement predictions made based on the results of these investigations were compared to actual settlement monitoring data obtained during construction. The paper presents a summary of geotechnical data pertinent to settlement predictions and monitoring as well as a detailed discussion of the advantages and shortcomings of the various field and laboratory techniques used to evaluate soil compressibility.
