This paper shows the case of Ravenna, an italian town, subject to troubling phenomenon of anthropic subsidence. This is mainly due to the unchecked withdrawal of water from the subsoil. The control of the settlement due to subsidence was made by means of performing periodic precise levellings on the land in the 70's and 80's.

Abstract

This paper shows the case of Ravenna, an italian town, subject to troubling phenomenon of anthropic subsidence. This is mainly due to the unchecked withdrawal of water from the subsoil. The control of the settlement due to subsidence was made by means of performing periodic precise levellings on the land in the 70's and 80's. In the other hand, the analysis of the subsidence made use of geotechnical information obtained through soil samples, taken during two deep boreholes driven down to -500 and -1500 meters. In this paper, the main results obtained with geotechnical laboratory tests are summarized.
