Integrated Geophysics Methods For Post Foundation Student Phase One, Faculty Of Social Science And Humanities, Federal University Oye Ekiti, Ekiti State

ABSTRACT

A combined geophysical method involving very low electromagnetic method. magnetics and electrical resistivity methods were used in delineating the causes of crack in the building at Faculty of social Science and Humanities Oye Ekiti, Ekiti, State. Five (5) VLF-EM traverses were established in both east-west direction and also north-south direction were occupied in the building and Twenty-one (21) VES studies were also occupied around the building. The VLF-EM helped in the identification of conductive zone that have high peak ,positive filtered, pseudo section and 2-D VLF-EM models and lineament map that were interpreted in terms of structures. lithology. and thickness in the distressed building. The electrical resistivity help us in generating geoelectric section profiles. and also some maps on the study area. The interpretation shows that there is high conductive zone which the value ranges from 11.5- 102ohms-rn. I 9. 7- l 15ohms-m and 17. 7-281 ohms-m respectively and the thickness ranges from 0.3-2.1 m. 2.7-2.8111a nd 1.0-21.Jm respectively. Also the depth to bedrock value ranges from 1.0- 21.3111 respectively Also from the geoelectric section three layers were delineated in the study area which include the top soil. weathered layer and fresh basement. The YES curve types obtained were A,H.K and Q curves respectively in the study area. • It is concluded that the possible causes of the crack in the foundation study area is due to the presence or clayey material at the distressed building.
