The Radial Consolidation of Clay Soils Géotechnique

2015-5-25  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 ...

A large-strain radial consolidation theory for soft clays ...

2017-10-5  A system of vertical drains with combined vacuum and surcharge preloading is an effective solution for promoting radial flow, accelerating consolidation. However, when a mixture of soil and water is deposited at a low initial density, a significant amount of deformation or surface settlement occurs. Therefore, it is necessary to introduce large-strain theory, which has been widely used to ...

It was derived that micro-scale amount level of average pore radius of clay changed from 0.01 to 0.1 micron by an equivalent concept of flow in porous media. There is good agreement between the derived results and test ones. Results of experiments show that flow in micro-scale pore of saturated clays follows law of nonlinear flow. Theoretical analyses demonstrate that an interaction of solid ...
