Abstract : The urban expansion of the megacity of Kinshasa necessitates the occupation of marginal areas with precarious mechanical characteristics. The Yolo Sud IV district, located in the Funa plain, exhibits complex Quaternary sedimentation characterized by a sub-surface water table at 0.20 m. This study examines the mechanical response of the surface formations using an integrated approach combining geotechnical investigations (oedometer tests, dynamic penetration) and geophysical methods (Electrical Resistivity Tomography - ERT).

Keywords : Urban Geotechnics, Compressible Soils, Oedometer Consolidation, ERT, Kinshasa, Geogrids, Coffee Husk Ash.
