Estimating rockfall release scenarios based on a straightforward rockfall frequency model
2022<p>A realistic quantification of rockfall risk is crucial for an effective and efficient prevention of damages. The estimation of realistic block and event volumes as well as their release frequencies remain a major challenge and are often based on mere expert estimation.

Do Apparent "Precursory" Rockfalls Coincide with Large Rockfalls by Chance?
59th U.S. Rock Mechanics/Geomechanics SymposiumABSTRACT: Rockfalls present a hazard to infrastructure, particularly for slopes along major roadways. Rock slope monitoring studies have linked large failures with the presence of previous, smaller spatially co-located precursory rockfalls.

Process analysis of rockfalls with stationary terrestrial LiDAR and RockFall Analyst
2011Rockfalls are a hazard concern for many transportation corridors in Alberta and British Columbia. A method of analyzing and further understanding rockfalls could help to reduce the hazard potential that rockfalls present. Rockfall hazard assessments are carried out in three steps: (1) identification of hazard zones, (2) site investigation to establish ...

Three-dimensional model for rockfalls Assumes point-like boulders Simulates trajectories from user-defined starting points Simulated trajectories: falling, bouncing, rolling Boulders stop when kinetic energy is exhausted by friction Input: digital elevation model (here, 10 m national DEM, 300,000 km2) Ancillary data: terrain geological/lithological ...

Modelling Rockfall Protection Fences
2008The paper reports an analytical formulation of a block impacting into a metallic net of a rockfall protection fence able to evaluate the net elongation and its braking time. The analytical procedure has been calibrated through a comparison with the experimental results of full-scale impact tests carried out in a vertical-drop test site.
