A study for the requalification and safety against natural hazards of the environmental and building heritage of Sant’Agata de’ Goti (Italy)

摘要

The historical center of Sant’Agata de’ Goti (Campania region, Italy) is located on a steep and narrow cliff of pyroclastic soils and rocks, overlying a thick Miocene flysch formation, which makes it particularly sensitive to both landslide and seismic hazards. The paper describes the subsoil characterization and two urban design proposals submitted to the town municipality by a multi-disciplinary research team. The first proposal deals with the environmental requalification of a cliff side, by assessing the stability of the overlooking cavities and by reshaping and consolidating the rock slope through reinforced earth and nailing. The second one includes a site-specific evaluation of seismic response, addressed to verify the seismic safety of the foundations of a masonry historical building.
