+ | The paper discusses the performance of a novel tool based on computed tomography (CT) to evaluate sample quality in soft soils. This new technique is applied to the low-plasticity Mediterranean deltaic deposits found in the region of Castello d’Empuries at the Costa Brava, in Catalonia (Spain). Tube specimens of variable diameters retrieved using open samplers (Shelby) as well as Osterberg-type fixed-piston samplers were scanned in this study. Statistical analysis of the CT images allows to define a quantitative index of sample quality. Sample quality classification based on this new non-destructive CT-based measure compares well with quality classification based on the well-established recompression sample quality index, e/e0. | ||
