Abstract
The effect of flood analysis on the foundation investigation
of the proposed Gas-Fired Power Plant in Badagry, Lagos,
Nigeria was carried out using geophysical, geotechnical
and geographical information system (GIS) methods. The
subsurface information was obtained by using two
electrode arrays for the resistivity data acquisition.
Geotechnical data were obtained through two boreholes via
percursion drilling within the study area. The integration of
geophysical and geotechnical data reveals that the subsoil
materials comprises fibrous peat, organic silty clay, clayey
sand, sandy clay and sand. The analysis of the subsoil
conditions via geotechnical data shows the feasibility of
foundation around 25 m via piling while the safe grade
elevation has been worked out to be 6.672 m for 100yrs
return period via GIS approach. Thus, in order to avoid
adverse effect of flood on the proposed structure, the safe
grade elevation value has to be added to the foundation
floor.
