ESTABLISHMENT OF SOIL STRENGTH PARAMETERS AND SELECTED INDEX PROPERTIES USING ELECTRICAL RESISTIVITY METHOD

The strength parameter of soil is the most important aspect of ground engineering.
Therefore, quick and early indications on the engineering parameters of soil is essential
for many calculation purposes in geotechnical engineering design such as ground bearing
capacity and ground slope stability. Soil investigation (SI) incorporating bore hole
sampling provides the most reliable value of the relevant soil parameters for the purpose
of geotechnical design, yet it is time-consuming, expensive and invasive. As an
alternative, geophysical method has been found to be an attractive tool for delineating of
subsurface properties without soil disturbance. The primary objective of this research
work is to investigate the relationship between electrical resistivity and various soil
.parameters- The research work consists of field resistivity surveys, scuiJx>ring_and-SQi
characterization tests. Field survey includes ID vertical electrical sounding (VES) and 2D
resistivity imaging for comparison.
