Abstract
A new method for directly determining the coefficient of permeability of clays from the constant rate of strain consolidation tests was proposed by Yoshikuni et al. (1995). In order to confirm the reliability of this method, the constant rate of strain consolidation tests under three kinds of strain rates were carried out on four kinds of clays in this study. The permeability tests using a flow pump and the conventional consolidation tests were also carried out on the same clays for comparing the coefficient of permeability obtained from each test. As the results, it was found that the coefficient of permeability obtained by the proposed method from the constant rate of strain consolidation tests agreed with the coefficient of permeability obtained from the permeability tests.
