Description and Dynamic Analyses of the 1935 Luchedu Rock Avalanche in Sichuan, China
Geofluids, 2022 The Luchedu rock avalanche (LRA) that occurred in 1935 at the junction of Sichuan and Yunnan in Southwest China is a disaster chain of the rock slide, debris avalanche, and river blocking induced by heavy rainfall.

Natural Hazards and Earth System Sciences, 2022 . The fracturing and fragmentation of rock blocks are important phenomena that occur ubiquitously during the propagation of rock avalanches. Here, the movement of a rectangular rock block characterized by different joint sets along an upper sloped and ...

Frontiers in Earth Science, 2020 Since the retreat of glaciers after the Last Glacial Maximum, rock avalanches have occurred intermittently in Yosemite Valley, California. We investigated the distal portion of the oldest of these, the Royal Arches Meadow rock avalanche, which has been ...

Conceptual Framework of Energy Dissipation During Disintegration in Rock Avalanches
Frontiers in Earth Science, 2020 Rock avalanches usually progress through three consecutive phases: Detachment (Phase 1), Disintegration (Phase 2), and Flow (Phase 3). While significant advances have been achieved in modeling Rock Avalanche Phase 1 (Detachment) and Phase 3 (Flow), the ...

Rock‐and‐soil avalanches: Theory and simulation [PDF]
Journal of Geophysical Research: Earth Surface, 2009 We present a 2‐D Contact Dynamics discrete element model for simulating initiation and motion of rock avalanches, integrating hillslope geometry, Mohr‐Coulomb rock behavior, pore pressure before avalanche triggering, and avalanche trigger. Avalanche motion is modeled as a dense granular flow of dry frictional and cohesive particles.

Fragmentation and boosting of rock falls and rock avalanches [PDF]
Geophysical Research Letters, 2015 Fragmentation has been proposed as an important dynamical process in the propagation of rock avalanches. The occurrence of an intense block fragmentation inside a rock avalanche traveling on smooth inclined terrain followed by a flat region (a geometry common to many landslides) is first studied numerically by means of a discrete element 2-D code in ...

Seismic response and failure characteristics of granite slope using large-scale shaking table test
Rock and Soil Mechanics, 2022 Huge hazards are frequently caused by earthquake-induced rock avalanche. The study of dynamic response characteristics and failure mechanism of the rock slope in specific geological condition is a challenging issue in geotechnical engineering.

Ground thermal and geomechanical conditions in a permafrost-affected high-latitude rock avalanche site (Polvartinden, northern Norway) [PDF]
The Cryosphere, 2018 On 26 June 2008, a rock avalanche detached in the northeast facing slope of Polvartinden, a high-alpine mountain in Signaldalen, northern Norway. Here, we report on the observed and modelled past and present near-surface temperature regime close to ...

Journal of Rock Mechanics and Geotechnical Engineering, 2023 A massive rock and ice avalanche occurred on the western slope of the Ronti Gad valley in the northern part of Chamoli, Indian Himalaya, on 7 February 7, 2021. The avalanche on the high mountain slope at an elevation of 5600 m above sea level triggered a

MONITORING AND MODELLING OF ROCK SLIDES AND ROCK AVALANCHES
Italian Journal of Engineering Geology and Environment, 2013 Rockslides can appear in a large variety of types and with different characters which make difficult their understanding and the prediction of their behav- iour. This contribution highlights some of the most important steps in rockslide monitoring and modeling showing the relationships between them. Monitoring is a fundamental step in the understanding
