| Résumé : |
Northern Algeria is one of the most active regions in the world. Therefore, when building infrastructure, manufacturers are enormous difficulties, especially in some regions, including the CONDE-Smendou. In this region spend three of the most important infrastructures of Algeria, RN3, the railway line connecting Constantine Skikda and recently the East-West highway. This is the area where companies have struggled to develop some sections of the East-West highway, and this
because of the poor quality of materials "rock", but also because of the misinterpretation of investigations made by consulting firms.
We are mainly interested in this study the formation of the rocks of this region. In this context and varied geological and geomorphological complex, characterized by high tectonic activity and active seismic activity, we examined the morphological consequences of tectonic and erosion processes.
The main areas that we have discussed in this magister memory are the dismemberment and evolution of structural relief terrain and tectonic movements, analysis of regional structural morphological markers, active tectonics and seismic activity, then the study and characterization of the quality of the materials present.
The tools and techniques used in the context of this work include imaging and geomatics as well as litho stratigraphic correlation. Furthermore, X-ray analyzes on a series of samples allowed us to have a better characterization of materials and rocks making up this region.
After analyzing our different results, we were able to develop two morpho-structural maps (scale 1:
20,000). These cards made from the interpretation of aerial photographs, provide a wealth of information about the origin of morphological elements (scree cone droppings, landslides and solifluxion) and the origin of structural elements (fault scarps, dip and accidents). These maps reveal a rather complex fracture network that confirms the existence and the role played by some accident directions, their essential nature and the extent of their scopes. This data can help to update
the currently used map showing a relatively even terrain, moderately unstable geological and without morphological peculiarities. |
