Evaluation du potentiel archéologique du sol en milieu urbain

Abstract : Knowing the extense and thickness of cities' archaeological soil is crucial information in order to assess scientific knowledge, to value the intensity and use of the soil and to define strategies for research. Moreover, it is necessary to develop assessing methods suitable for the present heritage policy, aiming both at scientific and financial profitability.
This thesis aims at answering historical questions regarding cities, by assessing the informative potential of data available to archaeologists. It consists in grasping the means of formation of the urban space and socio-spatial elements, through the characteristics of the urban soil, resulting from human activities. More specifically, the analysis focused on assessing the thickness of the volume of the urban soil and its division into distinct functional layers, in the city of Tours and sites of comparison.
The crossroads between the vision of the archaeologist and that of the geotechnician enables the setting up of models on the production of stratification (maps charting the thickness of the archaeological deposit) and methods to model the heterogeneity of the deposit. Results have revealed that a theoretical 100-m² grid is enough to understand variations in the thickness of the deposit. Vertically, the scale of analysis necessary to distinguish the so-called “homogeneous” zones is roughly 10 – 25 cm.
On the scale of a site, an archaeologico-mechanical referential frame has been established for sites in Tours and Lyons. The study shows that the use of the PANDA penetrometer is capable of imporving the characterization of the archeological deposit. The elaboration of a common referential frame for a group of sites is, in the medium term, an issue which will allow the promotion of these advances.
