dc.description.abstract |
Resistivity survey is one of the geophysical methods which can be
used to identify subsurface ground conditions. The research is focused on
determining the bed rock depth, variation of soil overburden thickness and areas
suitable for ground water exploitations at the proposed site for Institute of
Technology, University of Moratuwa by using the Vertical electrical sounding. The
survey was carried out using Schlumberger electrode configuration along three
main profile lines, with 18 resistivity points. The results of the survey were provided
2-3 distinct geo-electrical layers overlying the bedrock. The first thin upper layer
represents of Sandy Silt/sandy gravel and second layer corresponds to lateritic soil.
The third represents the saturated soil materials with less resistivity. The forth layer
corresponds to the bedrock and the depth ranging from 8 to 26m from the surface.
Geo-electrical results based upon 1-D models, which were created by IXlDv3
software, provide a satisfactory approximation of the various soil and rock
components. Based on the above results, it is confirmed the soil overburden in the
Northern part of the site, constitutes an aquifer, with a thickness of about 1.3m
above the bed rock covering an area of about 100 m2. |
