This research deals with the analysis of rockfall motion and the importance of kinematic simulations as well as in situ tests in designing of protection measures. The study area is a talus slope located in Northern Italy (Provence of Sondrio), where rockfalls frequently occur. The positions and dimensions of fallen blocks were measured and used in the calibration process, performed through the back-analysis approach. The calibrated values of restitution coefficients were compared with those obtained from in situ tests, which were carried out on the examined slope. Looking at the resulting rock fall hazard, the bidimensional kinematic simulations were performed in order to individuate the most suitable location and dimensions of mitigation measures.

Abstract
This research deals with the analysis of rockfall motion and the importance of kinematic simulations as well as in situ tests in designing of protection measures. The study area is a talus slope located in Northern Italy (Provence of Sondrio), where rockfalls frequently occur. The positions and dimensions of fallen blocks were measured and used in the calibration process, performed through the back-analysis approach. The calibrated values of restitution coefficients were compared with those obtained from in situ tests, which were carried out on the examined slope. Looking at the resulting rock fall hazard, the bidimensional kinematic simulations were performed in order to individuate the most suitable location and dimensions of mitigation measures.File | Dimensione | Formato | |
