Confined Pressuremeter Tests for the Assessment of the Theoretically Back-Calculated Cross-Anisotropic Elastic Moduli
This study considered the determination of the elastic cross-anisotropic moduli of two base course materials. The cross-anisotropic moduli were back-calculated from a series of vertical and horizontal laboratory pressuremeter tests in a confined mold. First, a theoretical model of an expanding cylindrical cavity in an elastic cross-anisotropic confined medium was developed. Subsequently, an estimate of four (Ghh, µ'hh, µ'vh, µ'hv) of the five independent cross-anisotropic moduli were determined based on a fixed point iteration scheme, which processed the analytically back-calculated test results. Finally, in order to assess the estimated moduli, results of the finite element simulations of the pressuremeter lab tests were compared with the actual measurements.
