Shallow Foundation Analysis on Heterogeneous Soil Formation in the Niger Delta of Nigeria
Akpila, S.B; Eluozo, S.N

Assessment on the stability and deformation requirements of shallow foundations on heterogeneous soil formation was carried out, using both field exploration and laboratory analysis. Results showed that based on site topography a Raft foundation can be placed on top of the overlying clay layer and subsequently backfilled to meet the adjacent highway grade level. However, the raft foundation exceeded the maximum permissible deformation requirement. A compromise on stability and deformation requirements was reached by either increasing footing dimension or placing the Raft foundation on the underlying cohesionless silty and slightly silty sand formations at one meter below ground level.
