Comparison of Laboratory Data and Field Performance for Fills Subject to Hydrocompression


Over 120 laboratory response-to-wetting (hydrocompression) tests on engineered fill samples using various procedures were compiled from the literature and from private files of geotechnical engineers in the State of California. These data were grouped into three categories according to the level of relative compaction used for the fill; these categories were 85 to 89%, 90 to 91%, and 92 to 95% relative compaction. In addition, field performance data from nine sites were compiled, which recorded the magnitude of hydrocompression in deep fills compacted with a minimum 90% relative compaction specification. Comparison of the magnitude of hydrocompression settlements calculated from the laboratory testing with the recorded values at project sites showed general agreement.
