Abstract Building on the work of Fyodorov (2004) and Nadal (2012) we examine critical behaviour population saddles with fixed instability index k in high dimensional random energy landscapes. Such landscapes consist a parabolic confining potential part N ? 1 dimensions. When relative strength m is decreasing below value c , exhibit glass-like transition from simple phase very few points to comp...

Underground mining activity in the karst mountain southwestern China has induced several large-scale rocky landslides and caused serious casualties. At present, there is a lack of systematic research on formation mechanism this area using multi-method fusion technology. First, orthophoto images landslide obtained by UAV photography were used to analyze deformation characteristics landslide. Sec...

The absorbing "ricepile" model with stochastic toppling rules has been numerically studied. Local limited, local unlimited, nonlocal limited, and nonlocal unlimited versions of the absorbing model have been investigated. Transport properties and different dynamical regimes of all of the models have been analyzed, from the point of view of self-organized criticality. Phase transitions between di...

The phenomenon of toppling deformation and failure is common in slopes with anti-dip structures, especially soft metamorphic rock slopes. This paper aims to explore the instability mechanism layered landslides. Taking slope a mining area southern Qinling Mountains China as geological prototype, large-scale centrifuge model test numerical simulation based on combined finite discrete element meth...

The purpose of this study is to identify the leading causes slope instability along a local highway in Anhui, People’s Republic China. As part east expansion project, mountain range will be excavated create two-way, nearly 30 m wide highway. site’s topography consists hill with palm-shaped faces carved from limestone running its sides. geological characteristics and stability research area high...
