Abstract

This paper presents a geological and architectural integrated pilot study, aiming at the preservation of the Biet Gabriel-Rufael church, the worldwide known Ethiopian rock hewn monumental site protected by UNESCO since 1978. The main scoriaceous basalt level, embedded within the massive basalts, corresponds to the horizon within which the Biet Gabriel-Rufael church and all the other monuments of Lalibela have been carved. Many fracture systems of both natural (i.e. geological) and anthropic origin (these latter connected to the carving of the church), were recognized. The fracture pattern determined the subdivision of the church into different blocks that can behave independently, thus compromising the stability of the monument. A net of deformometers and fracture gauges was installed for the monitoring of the fracture system and a preliminary Finite Element analysis, following the approach used for underground excavations, was performed, with the aim of elucidate the mechanical behaviour of the rock. - (NF)
