• Abstract:
  Nine test sites across the state of Oklahoma were investigated using the Seismic Cone Penetration Test with pore water pressure measurement (SCPTu). Field testing was conducted during wet and dry periods to observe the effect of moisture conditions on the data collected from the field. Disturbed and undisturbed samples were collected at each site to conduct laboratory tests and determine the properties of the soils tested. Using the field and laboratory data, correlations proposed in the literature to predict various soil properties were tested for their applicability to Oklahoma Soils. Results showed that some existing and new correlations may provide reasonable first approximations of soil properties. However, there is considerable uncertainty with these correlations based on scatter observed in the comparisons to SCPTu and laboratory test data gathered in this current study. Additionally, it was observed that the moisture conditions at the time of SCPTu has a considerable influence on predicted soil properties.
