Abstract
For contaminated clay soils, it has been found that current testing methods to determine compressibility characteristics do not truly identify the physico-chemiral interaction present in the soil-pore fluid-electrolyte system. Most methods are virtually impracticable due to various reasons such as evaporation of pore-fluid, difficulty of handling toxic chemicals, etc. Also, destructive test methods may not maintain in-situ conditions while testing.
The electrical properties of soils, the dielectric dispersion in particular is considered to represent the amount of physico-chemical interaction present in the soil-pore fluid-electrolyte system. For uncontaminated soils, correlations between the dielectric dispersion and the slope of the isotropic consolidation line has been previously established.
In this thesis, it is attempted to extend the above correlation for chemically contaminated soils considering the physical and chemical effects pertaining to the pore fluid. The optimized electrical parameters such as the dielectric constant and the conductivity of the soil clusters as well as the solution, geometric parameters reflecting the fractions of the above two phases are calculated for different water contents corresponding to different loading conditions.
