Summary

This paper presents the methodology adopted for assessing experimental parameters relevant to computer rockfall analyses and describes the data gathered from several in situ rockfall tests carried out by ISMES and ENEL CRIS during recent years.

Through the calculation of block velocities during their fall from and onto slopes of various geometry, and the measurement of the run-out distances, heights of bounce and the geometric characteristics of blocks, the following experimental parameters were studied: Restitution Coefficient, Rolling Friction Coefficient, dispersion of trajectories, effect of block geometry on its fall, and efficiency of a ditch, at the bottom of a slope, for arresting fallen blocks.
