Miniature cone penetration testing (CPT) is now widely used in centrifuge modeling. A common approach for interpreting the test results is to normalize the measured cone tip resistance,qc, to the value that would be measured in the same soil at an effective vertical stress of 1 atm,qc1. However, most overburden normalization methods are derived from CPTs performed in calibration chambers or from CPTs performed in the field in relatively uniform deposits. This paper summarizes measurements from in-flight miniature CPTs performed in clean sand centrifuge models where tip resistances were measured continuously to an effective vertical stress larger than 1 atm without any significant boundary effect or particle size effect. Based on these test results, the authors present a centrifuge CPT-specific overburden normalization for a wide range of sand relative densities, ~40%–90%. The in-flight miniature CPT data suggest that the overburden normalization exponentmgenerally is insensitive to relative density and is somewhat larger than the values computed using methods from the literature.
