Abstract
This paper describes the effect of the initial volume ratio f0 (or the initial water content w0) on the rate of self-weight consolidation of dredged clay as well as the effect of the expressive form of the consolidation characteristics, by examinations on results of the consolidation calculation by means of the finite deferential method. The consolidation characteristics such as the compression curve were considered to express either the arithmetic f or the logarithmic f in calculations performed with different f0 (or w0) conditions. It was found as conclusions that the faster rate of self-weight consolidation was observed in cases of the arithmetic f was considered, and the rate of consolidation became faster with an increase of f0. It is also found that the stable calculation can be performed if consolidation characteristics were expressed in log f form even though a large interval of time difference was configured. In contrast, the short interval of time difference was needed to obtain stable results from calculations with the arithmetic f expressive form.
