Repair and strengthening of the foundations of ancient buildings in acireale city (Sicily)

摘要

This paper describes the strengthening of the foundations of some historical buidings in Acireale, a town in the outskirts of Catania in eastern Sicily after a flood in 1995 which caused differential settlements in the foundations and damage to the masonry structures. After a brief seismological history of the area and the description of the geotechnical investigation carried out to establish the properties of the fondation soil, the underpinning of the existing foundation by micropiles and its enlargement by r.c. beams is reported.
