| Abstract: | In Mila Province, Algeria (a.k.a Mila Wilaya), sensitive clays presenting shrinkage-swelling phenomena are widespread, covering
large areas. Due to this, constructions and infrastructures sustainability built on such soils is questionable. Such clays
sensitivity is amplified by seasonal rainfall deficits which reaches extreme magnitudes. In order to develop disasters’ prevention
measures, we present in this work, areas mapping susceptible to shrinkage-swelling phenomenon by adopting a French method
developed by B R G M. This method takes into account three measurable characteristics: i.e. lithological, mineralogical and
geotechnical, of clayey formations identified in the studied sector. Based on these characteristics, three scores are attributed
for each formation. Then, the susceptibility index is the obtained score average for each clayey formation. The susceptibility
map is established on this index basis with three classes: low, medium, high. |
