Abstract
Axial pile design approaches based on CPT data have recently been developed for low-medium density chalk ground conditions, while numerical modelling of similar boundary value problems has proved useful in understanding better pile behavior and aiding the interpretation of field and physical tests. In this paper a simple method to calibrate an advanced constitutive model for soft rocks is presented. To this end a newly developed soft oedometer apparatus able to measure both axial and radial stresses is used to perform 1D compression tests of low-medium density chalk samples. The calibrated large strain constitutive model is then used to perform a numerical simulation of a CPT installation in chalk. The results are compared to field data, showcasing the models’ capabilities, and highlighting the potential of the soft oedometer for the calibration of constitutive models without the need of triaxial test data.
