ABSTRACT
Cone penetration tests (CPT) are one of the basic tools of geotechnical soil characterization. Calibration Chamber tests (CC) provide an effective way to study CPT in sands under strictly controlled conditions (material, density, stress state and boundary). Results from CC tests are used to establish relationships between the observed outcomes like cone resistance (qc), and the material descriptors like relative density (DR) and effective stress state (σ ′).
