    Abstract

    In this paper, one-dimensional consolidation and permeability tests are conducted to investigate the compressibility and permeability of reconstituted marine clay that has been used as filling material for a land reclamation project in Tianjin, China. A curve-fitting method is used to best fit the measured consolidation and permeability data to determine the void ratio–effective stress relationship (compressibility) and hydraulic conductivity–void ratio relationship (permeability). Relatively good agreements are found when comparing the obtained relationships with model test data of reconstituted clays in literature. The proposed relationships could be used as preliminary tools for the calculation of the compressibility and permeability of the reconstituted clays in land reclamation projects.
