The consolidation of soils involves two interdependent processes. These are fluid (air and water) flows and the deformation of the soil structure. The two processes tend to be treated separately, especially in the common commercial softwares. This paper illustrates a technique for utilizing these two types of software simultaneously to perform a coupled consolidation analysis. Theoretical formulations and two example problems are presented to illustrate the proposed method. The coupled analysis results exhibit the classic Mandel-Cryer effect as commonly shown in analytical solutions.
