| dc.description.abstract | Rockfall cases are a natural and dynamic geologic process, commonly occur within mountainous areas near by the cliffs undercut by human for developing building or highway. This paper simulated rockfall process within manmade slope in the quarry at the Kloch, Austria. This paper revealed 7 (seven) slope surface parameters for this slope, including; dynamic and static friction angles (350), normal and tangential damping (0.2 and 0.95 consecutively), rolling resistance (0.2 to 0.3), amplitude of roughness (0), and frequency of roughness (1). These results were than treated as an input data in the simulation of the designated rockfall. Based on the simulation results, it was identified that the Kloch slope height was 15 m, the rocfall would yield the kinetic energy of 240 kJ, and 0.5 m of bouncing height. Hence, in order to protect toe area from the rockfall risks, it is recommended to construct a minimum 1 m height of retaining wall with a capacity to restrain the rockfall kinetic energy up to 500 kJ as an appropriate barrier for this case | en_US |
