Correlation of Field and Laboratory Electrical Resistivity with Strength Properties of Soil

This Final Year Project involves the correlation of field and laboratory electrical
resistivity with strength properties of soil. In general, this report embraces the use of
electrical resistivity (ER) and geotechnical laboratory soil testing methods to obtain
soil resistivity and soil strength properties.
The objective of this study is to find correlation between field and laboratory
electrical resistivity with strength properties of soil such as cohesion, Internal Angle
ofFriction, moisture content, unit weight, and plasticity index.
Field electrical resistivity was conducted at a particular location at University
Teknologi PETRONAS (UTP) in the vicinity Block 13. From the same location two
boreholes were drilled and soil samples were extracted using Percussion Gouges
Gasoline Driven Hammer. Laboratory electrical resistivity and geotechnical
laboratory tests were further carried out on the soil samples.
The results obtained were compared and correlated with soil strength properties
obtained from the two boreholes. Results from both the boreholes and electrical
resistivity survey located at the boreholes locations indicated that there were
consistent in the correlation between the resistivity and soil strength properties. The
results indicated that there are some correlation between moisture content, internal
angle of friction, and plasticity index with electrical resistivity (Field and laboratory).
However, it shows lack of correlation between unit weight and cohesion with
electrical resistivity.
This final year project report covers background study, literature review,
methodology & tools, results & correlations, and conclusion & recommendations on
the title of this study.
