Artykuł dotyczy miasta San Leo, znanego z atrakcyjnych zabytków historycznych, zwłaszcza twierdzy Rocca Fortezza stanowiącej architektoniczne arcydzieło. Jest ona położona na wysokiej skale, której zbocza od setek lat ulegały procesom osuwiskowym. Najpoważniejsze osuwisko miało miejsce w 2014. Aby uniknąć potencjalnej katastrofy i zapewnić bezpieczeństwo miastu, w pracy przeprowadzono analizę proaktywną, polegającą na przewidywaniu problemu i podejmowaniu działań w celu zminimalizowania możliwych trudności związanych ze statecznością obiektów. Parametry geomechaniczne określono metodą analizy wstecznej dla przekroju, w którym wystąpiło ostatnie rozległe osuwisko. Obliczenia numeryczne wykonano przy użyciu metody elementów oddzielnych (DEM). Dla wyznaczonych parametrów przeprowadzono analizę stateczności i deformacji w przekroju potencjalnie niekorzystnym. Ponadto przeanalizowano przekrój klifu znajdujący się bezpośrednio pod twierdzą, dla którego zaproponowano środki stabilizujące.

The paper is about the town of San Leo, known for its attractive historical monuments, especially the Rocca Fortezza fortress, which is an architectural masterpiece. It is situated on a high rock, the slopes of which have been subject to landslide processes for hundreds of years. The most serious one occurred in 2014. In order to avoid a potential catastrophe and ensure the safety of the city, the study conducted a proactive analysis, which consists of anticipating the problem and taking appropriate measures to minimize unforeseen difficulties. Geomechanical parameters were determined using the back analysis method for a cross-section located in the vicinity of the city, where the last extensive landslide occurred. Numerical calculations were performed using the distinct element method (DEM). A stability and deformation analysis was carried out for the determined parameters in a potentially unfavorable cross-section located nearby. In addition, a crosssection of the cliff directly below the fortress was analyzed, for which countermeasures were proposed.
