  • The Radial Consolidation of Clay Soils Géotechnique

    2015-05-25· Synopsis The radial consolidation theory of Barron (1948) and McKinlay (1961) has been extended to take account of smear at the drainage boundaries, a decreasing permeability and compressibility and non-linear structural viscosity for an homogeneous anisotropic clay. An engineering assessment is made of the errors likely to result in using laboratory ch values to predict field rates of
