Modification of rock mass rating system: Interbedding of strong and weak rock layers
Journal of Rock Mechanics and Geotechnical Engineering, 2017 Rock mass classification systems are the very important part for underground projects and rock mass rating (RMR) is one of the most commonly applied classification systems in numerous civil and mining projects.

Crack propagation speeds in weak snowpack layers
Journal of Glaciology, 2022 For the release of a slab avalanche, crack propagation within a weak snowpack layer below a cohesive snow slab is required. As crack speed measurements can give insight into underlying processes, we analysed three crack propagation events that occurred ...

Eigendegradation Algorithm Applied to Visco-Plastic Weak Layers
Applied Sciences, 2022 In geotechnical engineering, very often, the soil behavior varies with time. This is of particular interest in many cases such as embankments in soft clays, shear band progression in slopes or where the speed of the application of the load affects the ...

Dynamic response of down-dip multi-weak-layer rock slope under earthquake
Zhongguo dizhi zaihai yu fangzhi xuebao, 2021 The long-term mining of the Fushun West Open-pit Mine has resulted in the exposure of underground rock layers, forming numerous down-dip and weak-layer rock slopes.

Modeling snow slab avalanches caused by weak-layer failure – Part 1: Slabs on compliant and collapsible weak layers [PDF]
The Cryosphere, 2020 Dry-snow slab avalanche release is preceded by a fracture process within the snowpack. Recognizing weak-layer collapse as an integral part of the fracture process is crucial and explains phenomena such as whumpf sounds and remote triggering of avalanches

Stability of Embankments Resting on Foundation Soils with a Weak Layer
Geosciences, 2021 The presence of weak layers in geotechnical systems, including soil or rock masses, both natural and man-made, is more frequent than is normally believed.

FEM Modelling of Thin Weak Layers in Slope Stability Analysis
Geosciences, 2023 Modelling the presence and the effect of a thin weak layer of soil or rock in a slope stability analysis performed through the finite element method (FEM) presents several problems of purely numerical nature.

Dynamic crack propagation in weak snowpack layers: insights from high-resolution, high-speed photography [PDF]
The Cryosphere, 2021 Dynamic crack propagation in snow is of key importance for avalanche release. Nevertheless, it has received very little experimental attention. With the introduction of the propagation saw test (PST) in the mid-2000s, a number of studies have used ...

Mechanical behaviors of deep pillar sandwiched between strong and weak layers
Journal of Rock Mechanics and Geotechnical Engineering, 2023 A variety of coal room and pillar mining methods have been efficiently practiced at depths of up to 500 m with least strata mechanics issues. However, for the first time, this method was trialled at depths of 850–900 m in CSM mine of Czech Republic.
