The rate of consolidation for a clay cylinder with external radial flow of water is usually analyzed by the solution, which is presented by I. Da Silveira as a solution of the consolidation equation of Terzaghi in radial case, independent of the deformation condition of a clay cylinder. However, it is well known from laboratory test results that the rate of K0-consolidation differs from that of isotropic consolidation.In this study, processes of consolidation for a clay cylinder with external radial drainage are investigated under four conditions as an application of the consolidation theory proposed by H. Yoshikuni. The prepared conditions for calculation of consolidation are as follows; 1) The K0-consolidation with the average vertical load kept constant. 2) The K0-consolidation with radial load kept constant. 3) The isotropic consolidation with load kept constant. 4) The no vertical strain consolidation with radial load kept constant.
