In general practice, soil investigation (SI) incorporating bore hole sampling will perhaps produce the most reliable value of the relevant soil parameters for the purpose of actual calculation on factor of safety (FOS) in slopes. however, bore hole sampling is in general time consuming and very expensive. This project is a part of the whole research which is to implement a quick method of establishing the factor of safety in slopes by replacing the conventional soil parameters such as cohesion and angle of internal friction with electrical parameters such as resistivity. hence, eliminating the need of the more elaborate bore hole sampling which is very high in maintenance cost. This research is fiocusing on finding the correlation between resistivity and some soil parameters. In this paper, a sandbox resistivity testing has been conducted for soil samples at two difTerent locations and for each sample, the moisture content varies from 20%, 30% and 40%. It is an appropriate method mainly to collect the resistivity data in the laboratory, and far analysis purposes. The experiments involved resistivity sandbox, moisture content, particle size distribution and direct shear test. Direct shear tests were performed for each sample in order to investigate the strength behavior of soil due to the various amount of water content. Initial correlation is found and subjected to further testing firr better findings
