This study was carried out after the realization of numerous geomechanical analyses, finalized to the stability analysis of rock walls during a carriageway widening in a mountainous area. With this aim, a cartography based on SMR Index of Romana was realized, through a spatial analysis of both geomechanical parameters and the distribution of the discontinuities. This approach therefore allowed the estimation of the potentially unstable zones for each area and their classification on the basis of the resulting stability degree. Such methodological approach could find an important application above all in scarcely accessible zones, where, however, a good structural homogeneity exists. This methodology was elaborated during geomechanical surveys, aimed at the realization of structural engineering works in the Middle Valley of the Serchio River. The purpose of the study consisted in the determination of the corrected profile of the slope based on the stability conditions of the rock masses and the consequent planning of eventual works as support. The data elaboration allowed the individuation of the most critical areas, prone to sliding or toppling. This study revealed particularly suitable to experimentation, because it regarded a meaningful area with spatially homogenous geological/geomechanical/structural situation. The data obtained, appropriately compared with traditional methods, showed a good degree of reliability.

Abstract
This study was carried out after the realization of numerous geomechanical analyses, finalized to the stability analysis of rock walls during a carriageway widening in a mountainous area. With this aim, a cartography based on SMR Index of Romana was realized, through a spatial analysis of both geomechanical parameters and the distribution of the discontinuities. This approach therefore allowed the estimation of the potentially unstable zones for each area and their classification on the basis of the resulting stability degree. Such methodological approach could find an important application above all in scarcely accessible zones, where, however, a good structural homogeneity exists. This methodology was elaborated during geomechanical surveys, aimed at the realization of structural engineering works in the Middle Valley of the Serchio River. The purpose of the study consisted in the determination of the corrected profile of the slope based on the stability conditions of the rock masses and the consequent planning of eventual works as support. The data elaboration allowed the individuation of the most critical areas, prone to sliding or toppling. This study revealed particularly suitable to experimentation, because it regarded a meaningful area with spatially homogenous geological/geomechanical/structural situation. The data obtained, appropriately compared with traditional methods, showed a good degree of reliability.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
