Abstract

In order to estimate the structural competency of the sub-surface geological features of the Construction  site, the application was performed for data attainment using Schlumberger configuration of the resistivity  profiling and Vertical Electrical Sounding (VES) around outer ring road of Mysore City. A 1D numerical  reversal of discrete DC resistivity was applied to boost the results for better accomplishment of the study  objective. For the edifice of geo-electric sections displaying the key geo-electric physiognomies of the  geological entities existing in the subsurface region, the data obtained from the VES techniques were used. The interpretation outcomes reveals the geo-electric segments comprise of 3 to 4 layers explicitly:  vegetative topsoil, highly weathered silty loam soil, moderately weathered rock and massive hard rock. The  stratum thicknesses and resistivities vary from 1.2 - 1.55 m/31 - 132 Ohm-m, 0.2- 3.875m/ 24 - 300 Ohm m and 2.5 – 12.76 m/ 27.2 – 1000 Ohm-m and 50 – 1840 Ohm-m respectively. Based on geophysical  study of the region states, design of shallow substructure for average civil engineering projects in the  extremely and moderately weathered layers are the most competent beds and for multistoried structures,  the undeformed hard rock zone is formidable.
