Statistical analysis of rockfall volume distributions: Implications for rockfall dynamics [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2003
We analyze the volume distribution of natural rockfalls on different geological settings (i.e., calcareous cliffs in the French Alps, Grenoble area, and granite Yosemite cliffs, California Sierra) and different volume ranges (i.e., regional and worldwide catalogs).

Repetitive Rockfall Trajectory Testing [PDF]

open access: yesGeosciences, 2018
Numerical simulations of rockfall trajectories are a standard procedure for evaluating rockfall hazards. For these simulations, corresponding software codes must be calibrated and evaluated based on field data. This study addresses methods of repeatable rockfall tests, and investigates whether it is possible to produce traceable and statistically ...

Semi-Automatic Determination of Rockfall Trajectories [PDF]

open access: yesSensors, 2014
In determining rockfall trajectories in the field, it is essential to calibrate and validate rockfall simulation software. This contribution presents an in situ device and a complementary Local Positioning System (LPS) that allow the determination of ...

Preliminary analysis on basic characteristics and mechanism of rockfalls in layered red rocks with gentle dip angle: A case study of the Tiejiangwan rockfall in Hongya County, Sichuan Province

open access: yesZhongguo dizhi zaihai yu fangzhi xuebao, 2023
Gentle dip angle rock slopes are often developed in layered red rocks, which are prone to geological disasters due to the combination of soft and hard lithology.

Rockfall Zoning Based on Rockfall Trajectory in GIS Case: Haraz road (Emamzadeh Ali) – Amol [PDF]

open access: yesجغرافیا و توسعه, 2013
In this paper, Geographic information system (GIS) modeling is used in combination with three-dimensional (3D) rockfall process modeling to assess rockfall hazards. The 3D rockfall model considers dynamic processes on a cell plane basis.

Evaluation of Rockfall Hazard Based On UAV Technology And 3D Rockfall Simulations [PDF]

open access: yes, 2021
Abstract In this study, the rockfall hazard in Hacıabdullah village located in the Central Anatolia region of Turkey was assessed with three-dimensional (3D) rockfall analyses based on unmanned aerial vehicle (UAV) technology using RAMMS (Rockfall software). With several rockfall disasters experienced in the village, the final event occurred in

Study of Passive Protective Net Protecting the Rockfall Caused by Open-Pit Blasting on High and Steep Slope

open access: yesShock and Vibration, 2021
In order to prevent rockfall caused by open-pit blasting on the high and steep slope and ensure that the passive protective net structure has sufficient impact resistance, the mechanism of blasting flyrock causing rockfall is analyzed by using ANSYS ...
