摘      要：Back-analysis is broadly used for approaching geotechnical problems when monitoring data are available and information about the soils properties is of poor *** landslide stability assessment back-analysis calibration is usually carried out by time consuming trial-and-error *** paper presents a new automatic Decision Support System that supports the selection of the soil parameters for three-dimensional models of landslides based on monitoring *** method considering a pool of possible solutions,generated through permutation of soil parameters,selects the best ten configurations that are more congruent with the measured *** reduces the operator biases while on the other hand allows the operator to control each step of the *** final selection of the preferred solution among the ten best-fitting solutions is carried out by an *** operator control is necessary as he may include in the final decision process all the qualitative elements that cannot be included in a qualitative analysis but nevertheless characterize a landslide dynamic as a whole epistemological subject,for example on the base of geomorphological evidence.A landslide located in Northeast Italy has been selected as example for showing the system *** proposed method is straightforward,scalable and robust and could be useful for researchers and practitioners.
