Soil-structure interface studies for offshore piles
Abstract eng: The effect of different salinity sedimentation environments on marine clay-pile interface and the effect of particle crushing on marine sand—pile interface are presented with two laboratory studies. Kaolinite is consolidated under different salinity values representing the range for Black Sea to Red Sea and split samples of clay and concrete are subjected to interface direct shear tests. The same concrete pile has nearly twenty per cent higher shaft capacity in higher salinity when compared to that of at lower salinity. Cold bonding palletization technique is used to manufacture crushable artificial sand from fly ash with similar behavior of calcareous sand. Interface direct shear tests are conducted on split samples of concrete and pellets. Mechanical sieving is conducted before and after the shearing to quantify the crushing. At low normal stresses The dilative behavior at low stress levels during shear is inhibited due to particle crushing.
