PHYSICAL ANALYSIS AND INVERSE METHODS APPLIED TO ARCHAEOLOGICAL FIRE REPLICATIONS ON ATACAMA DESERT SOILS, NORTHERN CHILE

Résumé

Physical analysis of in situ fire experiments on soils are useful for the estimation of subsurface thermal diffusivity, which is affected by factors like water, heterogeneity and heating conditions. To address the uncertainties of these factors, a new data processing based on inverse methods was developed and experimentally applied to soils from an archaeological site in the Atacama Desert, Chile. By combining experimental data and numerical simulations, we determined the dominant physical processes arising during the heating. Our analysis succeeded in defining practical procedures to obtain a more accurate estimation of the diffusivity values, thus reducing the above-mentioned limiting factors.
