- Uncertainty on the use of the cone penetration test for silts compromises the safety of ground structures. Challenges posed by the small size of silt grains have prevented quantitative particle-scale studies that could help explaining the mechanisms underpinning the drainage patterns. This is the first study to link the change in orientation of the silt grains during cone penetration with drainage patterns. The findings contribute to explain the phenomena controlling the cone resistance and the development of pore pressures and are, thus, of utmost importance to accurately determine the geotechnical parameters for engineering design.
