Abstract: In analyzing consolidation settlements caused by time dependent loading, the engineer typically replaces the actual load-time curve with a series of step loads and applies the theory for instantaneous loading. For the case of one-dimensional vertical flow and simple ramp loading, the time-settlement curve may be approximated using a graphical construction orginiated by Terzaghi or curves presented by Schiffman. However, the method is reviewed and suitable design curves are presented. For one-dimensional vertical flow all of the assumptions of Terzaghi.s basis theory are retained except the assumption of instantaneous loading. For the sand drain case, solutions are obtained for purely radial flow and for combined vertical and radial flow.
