APPLICATION OF GEOPHYSICAL INVESTIGATION TO THE SYSTEM EARTHING OF BUILDINGS AT THE PHASE II OF FEDERAL UNIVERSITY OYE-EKITI, NIBGERIA

Abstract

Geoelectric method was employed in the investigation of the subsoil around the Phase II of the Federal University, Oye Electrical Earthing. Horizontal Profiling using Wenner array, Vertical Electrical Sounding were employed along four traverses in the area. The geoelectric sections developed from VES interpretation revealed four subsurface geologic layers, which comprise of the topsoil bedrock thickness ranging from 0.65 to 1.1 resistivity values range from 140 14.0 m. The third layer is made up of the from 38 to 384 basement bedrock varies from 314 to 885 also revealed averagely low resistivity topsoil. electrical problems experienced in Phase II, Federal University Oye soil related earthing problem because of the suitability of the topsoil. However, the areas from station 100 most suitable area for earthing sensitive laboratories and equipment.
