A standard method to determine the liquefaction resistance of clean sands over a range of depths based on in-situ cone penetration tests is to convert measured cone penetration resistances (qc) to an equivalent cone penetration resistance expected at an overburden stress of one atmosphere (qc1) using the overburden correction factor (CN). The method assumes that cone penetration resistance is normalized to an equivalent cone penetration resistance at an overburden stress of one atmosphere for the same relative density or state parameter. Numerous methods have been developed to normalize cone penetration resistance based on a constant state parameter (state normalized penetration resistance) as a method for representing the effect of overburden stress on liquefaction resistance. Several of these methods yield considerably different results of state normalized penetration resistance. The goal of this research is to compare three methods used to determine state normalized cone penetration resistance at a reference stress of one atmosphere for four well studied clean sands. Cone penetration theory and empirical relations of the different frameworks are reviewed. Calibration chamber data of the four sands is corrected for calibration chamber effects by two differing methods, corrected for lateral earth pressure effects, and converted to state normalized tip resistance using the evaluated methods. The resulting normalized tip resistances from the three methods are compared and checked for bias. Two measures of state, namely the state parameter and the relative state parameter, are compared to state normalized tip resistances for the four sands to determine whether either parameter minimizes the dispersion in the relationships, with insufficient conclusions. The interdependence between the crushing behavior of clean sands, the limiting compression curve, and state normalized tip resistance is evaluated, suggesting a correlation between the limiting compression curve and state normalized tip resistance. Finally, the overall correlation between the state or relative state parameter and the state normalized tip resistance is evaluated based on the data for the four sands. Two general correlations are shown corresponding to the two differing calibration chamber corrections, illustrating the expected scatter of estimated state for a clean sand. A background and review of the general correlations are provided.
