The relationship between porosity and electrical resistivity in cemented soil polluted by vitriol

The electrical resistivity of cemented soil is the basic parameter for describing its physical property, and closely related with its engineering mechanic indexes. It may be used to reflect the pollution characteristic of cemented soil. The relations between various parameters of cemented soil polluted by different vitriol solution concentration were studied. The result indicated that the electrical resistivity and formation factor have a close correlation with pollution degree and porosity. The relationship between porosity and formation factor in cemented soil polluted by vitriol follow Tumidajski's equation and Archie'law.
