Rockfall Hazard Analysis for Hong Kong Based on Rockfall Inventory
Rock Mechanics and Rock Engineering, 2003¶This paper compiles and analyzes the rockfall data in Hong Kong in the last fifty years. A simple rockfall hazard analysis is presented based on this rockfall inventory. A frequency-magnitude relation, which is analogous to the Gutenberg-Richter relation for earthquake occurrence, is proposed for rockfall, and direct correlation between rockfall ...

Three-dimensional rockfall modelling and rockfall protection – Port Hills
Proceedings of the 2013 International Symposium on Slope Stability in Open Pit Mining and Civil Engineering, 2013After the February 2011 Christchurch earthquakes Geovert were commissioned by the Canterbury Earthquake Recovery Authority (CERA) to provide the desperately needed answers to the widespread rockfall hazard. Including how best to protect people and assets, how much will it cost and how long will it take.

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.

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 ...

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.
