A STUDY OF THE SELF-WEIGHT CONSOLIDATION PROCESS OF VERY SOFT SOILS WITH NUMERICAL MODELING

In recent decades numerical modeling of self-weight consolidation of very soft soils which has a nnmber application in the analysis of consolidation of dredged materials and deposited materials behind tailing dams, has attracted special attention. In this paper, by considering large strain effects and variation of permeability and compressibility of soft soils during consolidation, and employing a new techniqne for discretization of spatial domain during stage filling, a finite difference based computer program has been developed that is capable of modeling different scenarios of self-weight consolidation. Then the performance of the model for analyzing of practical applications has been evaluated via comparing the model results with measured values in the site as well as compnter programs results that have been verified previously.
