Integrated analysis of data collected by an innovative monitoring system and results of a 3D numerical model in Boschetto landslide

摘要

This paper illustrates the studies carried out on a landslide phenomenon occurred during the Spring of 2013 in Boschetto, a little town in the Parma Apennines, after some days of heavy rain. The activation/reactivation of the landslide caused the interruption of a provincial road and the disruption of few houses. The work presented aims to reconstruct the process that caused the landslide activation. It describes also an innovative automated monitoring system that collects and remotely sends data. The main advantages of an automated monitoring system are the high acquisition frequency, the simultaneous recording of several physical entities. The large database of collected data and a statistical approach have been used for the analysis, in order to verify if accidental or systematic errors were present and eventually correct them. The results are shown together with the back-analysis simulation, made with 3D numerical model (GTS-NX) based on FEM and Mohr-Coulomb criteria.
