In the framework of numerical modeling of landslide triggering and evolution, two important issues, among others, must be addressed. One is about a reasonable reconstruction of local and global geometry of the involved geological structures of the system. The other one, with which we are mainly concerned in this paper, regards the problem of how to satisfactorily handle the spatial variability of important parameters related to the selected constitutive models. Thus, in order to explore the importance of different spatial distribution values of mechanical parameters on landslide numerical studies, we applied a methodology based on random number generation, already proposed by one of the authors, to carry out about fifty-three FLAC3D runs of the same model of an actual landslide. For each run, different sets of numerical values for the selected parameters have been automatically implemented. Finally some statistical considerations have been reported.

Abstract
In the framework of numerical modeling of landslide triggering and evolution, two important issues, among others, must be addressed. One is about a reasonable reconstruction of local and global geometry of the involved geological structures of the system. The other one, with which we are mainly concerned in this paper, regards the problem of how to satisfactorily handle the spatial variability of important parameters related to the selected constitutive models. Thus, in order to explore the importance of different spatial distribution values of mechanical parameters on landslide numerical studies, we applied a methodology based on random number generation, already proposed by one of the authors, to carry out about fifty-three FLAC3D runs of the same model of an actual landslide. For each run, different sets of numerical values for the selected parameters have been automatically implemented. Finally some statistical considerations have been reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
