Two centrifuge model tests were used to examine the effect of soil interlayering on the measured cone-penetration resistance in a layered soil model. The first centrifuge model included four soil profiles: two uniform loose and dense soil profiles and two two-layer sand profiles of loose over dense and dense over loose sands. The other centrifuge model involved a layer of loose or dense sand with varying thickness between overlying and underlying layers of low-plasticity clayey silt. Multiple cone-penetration soundings were performed using cone penetrometers with diameters of 6 and 10 mm. The results showed that the measured tip resistance in layered soils as well as the sensing and development distances depend on sand layer thickness and stiffness contrast between the subsequent soil layers. The results of these experiments were compared with the results obtained from analytical and numerical solutions. The results provide insights on the effect of thin-layer presence on cone tip measurements and an archived data set for evaluating design procedures and numerical analysis methods.
