Abstract—The stability of both natural and engineered
slopes has always been a major concern of geotechnical
engineers especially in recent years where an increasing
number of development are encroaching into hillside areas. In
tropical regions, soil slope failures due to frequent rainfall are
quite common. One of the long term objectives of this whole
research is to implement a quick method of assessing the factor
of safety (FOS) in slopes by replacing the conventional soil
parameters such as cohesion and internal angle of friction with
electrical parameters such as resistivity. However, this paper is
limited to the preliminary comparison of laboratory results
obtained from controlled laboratory soil samples and results
obtained from actual field samples. Results from both the
laboratory controlled samples and actual field samples shows
consistencies in the correlation between friction angle and
electrical resistivity while correlations between moisture
content and electrical resistivity shows a similar trend of
decreasing moisture content with increase of electrical
resistivity value.
Index Terms—Electrical resistivity, correlation, shear
strength, slope stability.
