PHYSIC-MECHANICAL CHARACTERIZATION OF THE CLAYEY SOILS OF ISSABA DEPRESSION IN THE SOUTH-EAST OF BENIN

Cover Page

Abstract


The instability of soils due to the swelling phenomenon is among others at the origin of enormous damages in civil engineering works, such the deformations, the cracking, the tear- ing, the wear of the rotation surface and the destruction of the foundations observed at the infrastructures level (housing, socio-community centers, covered road or not). This phenome- non is a very complex and particularly threatening situation for the different construction projects, in a lot of regions of the world where these types of soilsare met and at the level of which we note premature damages of the works. It urges then to make specific arrangements during the execution of infrastructures. The phenomenon described above is also present in Benin mainly in the depression of Lama.
