Example Application of the Rescaling Equation for CPT Inferred State Parameters in Loose Mine Tailings

Abstract

This work reassesses the state parameters (ψ) inferred from in situ cone penetration testing (CPT) using normalized tip resistance (Q_p) from the Rose Creek tailing impoundment in Canada that was previously introduced in the literature. For this reassessment, a recently proposed rescaling equation is used to modify the Q_p-ψ trendline calculated using CPTwidget software (v2.5). These reassessed ψ values are compared with independent values calculated from in situ gravimetric water content (ψGWC) and the critical state line (CSL) measurements. A good agreement between the inferred ψ and the in situ sample ψGWC is obtained using the rescaling equation.
