AbstractThe sensitivity (ratio of the natural strength to the remoulded strength) of Norwegian marine sediments reported in the literature shows an inverse relationship to the existing salt concentration of the pore water. These findings are explained by the "leaching theory " of sensitivity which is based on the premise that sedimentation took place in sea-water or brackish water. The decrease in the salt concentration of pore water by subsequent leaching and/or diffusion causes the salt-flocculated structure to become "metastable". This reduces the remoulded strength much more than the natural strength.
