520			_aThe Fredlund–Xing (1994) equation was proposed for relating the amount of water in the soil to soil suction. This relationship is commonly referred to as the soil–water characteristic curve. The equation is made up of three fitting parameters (i.e., afx, nfx, mfx) in addition to a Correction, C(ψ), function and can be applied over the entire suction range (i.e., fraction of 1–1,000,000 kPa). Each fitting parameter in the Fredlund–Xing (1994) equation is shown to have a primary meaning and significance as well as some secondary influence from the other fitting parameters. The primary and secondary influences are illustrated for a wide range of soil conditions. The Fredlund–Xing (1994) can be used to identify two important anchor points on the soil–water characteristic curve, namely the air-entry value and the residual point. The anchor points constitute the primary information required by the geotechnical engineers for the application of unsaturated soil mechanics. This paper presents results from a study of the relationship between the fitting parameters for the Fredlund–Xing (1994) equation and the anchor points that are pivotal to the interpretation of the soil–water characteristic curves.
