Abstract	The results of dilatometer tests (DMTs) performed in a calibration chamber on normally consolidated Cape Fear sand are presented and are interpreted with respect to both relative density and state parameter and are compared with those from calibration chamber tests on normally consolidated Hokksund and Ticino sands. The relationship between the amplification factor K sub D / K sub 0 and state parameter data for the Cape Fear sand tested and the combined data from the three sands discussed resulted in best-fit equations of the form K sub D / K sub 0 equals a times e supra m psi. In an effort to improve the ability of a single function to describe the amplification factor-state parameter relationship for the entire data base, normalization of the state parameter by the difference between the maximum and minimum void ratio and by the steady state void ratio at 10 kPa was investigated. However, neither of those normalizing factors produced a higher correlation coefficient for the best-fit relationship. The addition of the Cape Fear sand to the existing trend lines for the K sub 0 supra DMT / K sub 0 relative density relationship developed from data on Hokksund and Ticino sands suggests a limiting value of K sub 0 supra DMT / K sub 0 between 0.5 and 1.0 at low relative densities. At higher relative densities, a significant difference exists between the current data and that data obtained previously on the Hokksund and Ticino sands. Further study is needed to evaluate the potential influence of calibration chamber diameter on the measured results.
