New rockfall testing method of flexible rockfall barriers
2020Practical case studies show that current design procedures of rockfall nets do not consider all possible impact processes in natural terrain. Barriers fail because of a high component of rotational speed of the impacting blocks or hits to corner or end fields of the barrier section. A post hit to a barrier can be seen in Figure 1. Barriers are designed

Computer Simulation of Rockfalls
Environmental & Engineering Geoscience, 1989The Colorado Rockfall Simulation Program (CRSP) is a computer program written in BASIC which models rockfall behavior and provides a statistical analysis of rockfall simulations at a given site. This analysis can be used as a tool to study the behavior of rockfall, determine the need for rockfall mitigation, and design rockfall mitigation measures.

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 ...

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.
