Abstract: The installation process of a vertical drain with a mandrel normally causes a smear zone with reduced permeability around the drain. The smear zone affects the consolidation of the soil. This paper presents a new analytical solution for the consolidation analysis of soil with a vertical drain under ramp loading considering the smear effects. The solution is described in detail in this paper. A new normalised time factor, T, is suggested. It is shown in the paper that the average degree of consolidation exhibits very good normalised behaviour using this new factor T. Results are presented in tables and charts for practical applications. The influence of time-dependent loading is incorporated in the solution charts.
