Effect of porewater salinity on compression behaviors and hydraulic conductivity of soft marine clay
This study investigates the effect of porewater salinity on the compression behaviors of soft marine clay with multi-mineral compositions. A series of one-dimension compression tests were conducted with clays at different porewater salinity. The results indicate that the compression index decreases with increasing porewater salinity and can be described by a second-order polynomial equation, where the influence of porewater salinity is limited as the salinity increases to a threshold value. The normalized void indexes are taken from both ICL and EICL curves. It is believed that the compression behaviors of soft marine clay depend on the bentonite content. Hydraulic conductivity was back calculated based on empirical equations and is found to increase with increasing porewater salinity. Hydraulic conductivity is dominated by the inter-aggregated voids for soft marine clay at relatively high porewater salinity, and the influence of porewater salinity on the inter-aggregated voids of soil is limited at high salinity. A conceptual framework was presented to understand the changes in macroscopic soil behaviors with respect to the particles and pore fabrics of soil under the effect of porewater salinity.
