Stability of Embankments Resting on Foundation Soils with a Weak Layer [PDF]
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.

Geosciences, 2021 The presence of minor details of the ground, including soil or rock masses, occurs more frequently than what is normally believed. Thin weak layers, shear bands, and slickensided surfaces can substantially affect the behaviour of foundations, as well as ...

Preconditioning of sediment failure by astronomically paced weak-layer deposition [PDF]
Nature CommunicationsLow-strength sediment layers within continental slope strata precondition submarine sediment for failure, potentially leading to destructive tsunamis.

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

Failure characteristics and conditions of rock-coal combination structure with weak layer under dynamic and static stresses. [PDF]
Sci Rep, 2023 To comprehensively understand the mechanical response of a rock-coal combination structure containing a weak layer, a series of laboratory static loading and impact loading experiments were conducted.

Stress measurements in the weak layer during snow stability tests
Annals of Glaciology, 2023 The snow compression test is a snow stability test where an isolated column of snow is progressively loaded by tapping on it to induce failure in a possible weak layer.

Weak layer fracture: facets and depth hoar [PDF]
The Cryosphere, 2013 Understanding failure initiation within weak snow layers is essential for modeling and predicting dry-snow slab avalanches. We therefore performed laboratory experiments with snow samples containing a weak layer consisting of either faceted crystals or ...

Advances in Civil Engineering, 2019 Slope stability analysis is the most important problem in slope engineering design and construction. Open-pit slope often spans several strata, many of which are relatively weak. There may be faults and weak layers across the whole rock.

Modeling weak snow layer fracture in propagation saw test using an ice column model
Arctic, Antarctic, and Alpine Research, 2022 Fracture initiation and propagation in a weak snow layer are two primary processes of the slab avalanche formation process. This study proposes a model for the weak snow layer and investigates the fracture propagation process.
