Elaboration of the geotechnical map of ain temouchent-city (Algeria)

Abstract

The region of Ain-Témouchent is a seismic zone; its land is predominately agriculturaland shows complex structures, with many problems linked to the development of urbanized areas;these problems are directly or indirectly related to the geotechnical conditions of soil.The purpose of the present research is to build a database from the different measurements carriedout in the region, and to conduct tests in places where information is not available in order to considerthe entire perimeter of the study area.Once the database is completed, an analysis of all the data will be carried out using a numerical tool inorder to establish the geotechnical map of the city. This map will certainly allow all decision-makersand designers to have clear and precise information when proposing or designing new structures.The geotechnical mapping of Ain-Temouchent soils based on 178 observations divided these soilsinto ten groups. Eight of them according to the Unified Soil Classification System (USCS): CH (Highplasticity clay), CL (Low plasticity clay), MH (High plasticity silt), ML (Low plasticity silt), SC(clayey sand), SM (Silty sand), GM (Silty gravel with sand), OH (organic soil of high plasticity).The other two groups are rocky soils: basalts (hard volcanic rock with high resistance), and limeston turf (sedimentary rock).
