| Summary: | Consolidation theory is commonly applied on saturated soil that associated with
porous media layers below groundwater table. The actual condition shows that
consolidation phenomenon is also prevalent on unsaturated soil. Overburden on
consolidation process causing air to dissipate earlier than water, because air
compressibility value is higher than water compressibility value. Air dissipation
occurs gradually, causing air to come out from unsaturated soil condition that
gradually become saturated. When the saturated condition is achieved, then
subsequent water dissipation will occur in saturated condition, or commonly
referred as saturated consolidation.
The parameter that is often measured in the unsaturated soil is water content,
where the water content distribution in the soil is also closely related with the
infiltration process and evaporation process. The water content distribution
variation in unsaturated soil causes the hydraulic conductivity values also varies
based on the water content values. The hydraulic conductivity value variation has
an effect on the consolidation coefficient values, where the consolidation
coefficient values also varies to the hydraulic conductivity values. The variation of
consolidation coefficient values occured gradually and non-linearly.
Groundwater scientific developments, both in terms of engineering, science, and
technology, have brought a new future in groundwater scientific novelty. In this
research, Author studying a correlation between the distribution of water content
on unsaturated consolidation, that is expected a preliminary formulation on nonlinear
consolidation coefficient of unsaturated soil. Hopefully, this research
becomes a new insights into groundwater scholarly. |
