| Zusammenfassung |
The superimposition of geological formations with marked contrast in
geotechnical properties presents one of the most critical environments for
slope instability due to the different response of the materials to the
applied disturbances. Moreover, the above-mentioned geological setting is
often associated with high risk conditions, since many isolated rock slabs
located at a higher altitude than the surrounding countryside have been
sites of historical towns or buildings.
The purpose of the present paper is to investigate the mechanisms
determining instability in rock slabs overlying a soft substratum, with
reference to two cultural heritage sites in Malta. Accurate investigations have been carried out to evaluate the geological,
geotechnical and geomechanical properties together with the main
geomorphological features of the soft clayey substratum and the overlying
limestone rock mass.
The main instability processes have thus been identified and investigated
through kinematic analyses and numerical modeling, combined with a 1992–2001
Persistent Scatterers monitoring of ground displacements. The study
constitutes the basis for the subsequent restoration works. |
