چکیده مقاله:

The aims of this work are the evaluation of the vulnerability of landslides in pseudostatic and dynamic conditions, to produce slope stability maps, and the evaluation of the influence of stability process on infrastructures, using a GIS (۱). The analysis in pseudostatic condition, using the ordinary slice method, is carried out and the values of Kc (coefficient of critical horizontal acceleration) are evaluated; the analysis in dynamic condition is performed, using Newmark's (۲) method, and the value of the final displacement during the application of an accelerogram is calculated. The applied methodologies and the results for the area corresponding to the NE sector of the ۱:۵۰.۰۰۰ "Fabriano" (Marche Region, Italy) geological map sheet, are presented.
