摘要: Abstract A quick clay soil from a site close to the Grande‐Baleine River on west bank of Hudson Bay has been resedimented artificially. Specimens were formed at salinities 0.2 and 35 g/L simulate freshwater marine environments. Under consolidation pressure 50 kPa, specimens shown yield sensitivities 5 26, highest being for low‐salinity specimens. The natural sensitivity (as measured with fall cone) is greater than 300. initial compressibility soils low salinity lower those high salinity, but values higher pressures converge intact soil. artificial that reflects structuration latter. For soils, increases as decreases; this due mostly reduction in remolded strength. Results show freshly deposited can have void ratio results structur...
