monitoring process of the re-construction of an ancient structure: the baluarte do cavaleiro

the baluarte do cavaleiro is part of the stone masonry wall system existing in the city ofchaves of portugal and it is a construction dated from the xvii century. the baluarte docavaleiro is formed by three walls (north-east, ne; south-east, se; south-west, sw) andby two junction elements (designated here by cunhais). the se wall has suffered twocollapses recently. the main objective of this research work is to describe the monitoringprocess adopted to control the stability of the baluarte do cavaleiro and the adjacentconstructions that could be affected during the last rebuilding process of this wall. takinginto account that this rebuilding process included the total removal of this wall, it was alsopossible to identify the real geometry of the cross section of the wall, its building solution andthe type of the sustained soil. it was also possible to contribute for a better understanding ofthe structural behaviour of this kind of stone masonry construction.
