One Dimensional Consolidation of Double-Layered Foundation with Multi-Level Load

Abstract

An analytical solution for one dimensional consolidation of the double-layered foundation with vertical drainage under quasi-equal strain and a multi-level loading condition is studied in this paper. The analytical solution for one dimensional consolidation of the double-layered foundation has two solutions: one solution is the general consolidation solution for both single-surface and double drainage conditions; and another solution is a time-staged loading consolidation solution for both single and double drainage conditions. The average degree of consolidation has been calculated for each time-stage of loading. The consolidation response of a two-layered profile has been investigated. The consolidation settlement calculation of the expressway embankment foundation of Jiangsu marine clay is performed by the one dimensional consolidation of the double-layered foundation.
