Geophysical Investigation Of Road Failures, Using Seismic Refraction Survey: Case Study Of Ireukpen-Ozalla Road Axis, Ekpoma, Esan-West Local Government Area Edo State:- Omai Obinna M
ABSTRACT
This project work was carried out
at Ireukpen-Ozalla Road Axis Ekpoma, Esan-West Local Government Area Edo State.
Using seismic refraction prospecting method to examine the cause(s) ofthe
persistent failure ofthe road. An ABEM TERRALOC MARK-6 Seismometer was used as
the recording instrument and twelve geophones as wave detectors in series with
one another. The geophones were spread at predetermined distances and the
impact of a sledge hammer on a flat plate served as the source of generating
seismic waves. The “SERCOM1” software was employed in the interpretation of the
field result for the forward and reversed shooting respectively. From which the
subsurface reveals two layers of velocities, which are 980ms-1 and 1283ms-1 for
the forward shooting, 851ms-1 and 1276ms-1 for the reversed shooting
respectively. The investigation also shows that at twenty three metres (23 m)
from the surface ofthe forward shooting, clay deposit could be discovered. And
even at thirteen metres (13 m) from the surface ofthe reversed shooting clay
deposit could also be encountered. The form ofroad failure identified in this
study is due to subsidence associated with clayey material and the delineated
clayey water absorbing sections which are major geologic factors responsible
for road failure in the area.
