Geodetic monitoring and geotechnical analyses of subsidence induced settlements of historic structures

A comprehensive analysis of the Cathedral, Torre Civica, and Piazza Grande in Modena—part of a UNESCO World Heritage Site—reveals significant subsidence-induced settlements, driven by complex historical construction, subsoil conditions, and both natural and human-induced factors. The study integrates geodetic monitoring data from 1984 with advanced 3D finite element modeling to assess long-term structural behavior, particularly differential settlements that pose risks to the monuments' stability. By incorporating soil characteristics derived from laboratory and in situ tests, the model accurately predicts settlement profiles, aligning with high-precision leveling observations. This approach provides a proactive tool for conservation authorities to manage heritage safety by anticipating risk scenarios.
