Earthquake Dynamic Failure Mechanism of Dangerous Rock Based on Dynamics and PFC3D
Frontiers in Earth Science, 2021 The dynamic failure mechanism of horizontally layered dangerous rock during earthquakes is complex and only few studies have addressed the combination of particle flow code (PFC) meso-level failure mechanism and mechanical analysis.

Air Convection in the Active Layer of Rock Glaciers [PDF]
Frontiers in Earth Science, 2020 Coarse blocks are an abundant surface cover in mountainous permafrost landscapes. In this coarse blocky layer, air convection occurs and has a significant influence on the ground thermal regime of the underlying permafrost. Besides heat transfer through conduction, free convection of air takes place seasonally and leads to a pronounced ground cooling ...

Buoyancy-driven dispersion in a layered porous rock [PDF]
Journal of Fluid Mechanics, 2015 AbstractWe investigate the longitudinal dispersion of a passive tracer by a gravity-driven flow in a porous medium consisting of a series of independent horizontal layers connected to a constant pressure source. We show that in a formation of given vertical extent, the total flux is only weakly dependent on the number of layers, and is very similar to ...
