Rock Slope Stability Analysis Using Discrete Element Method
Rock slope stability depends very much on the strength features of the rock and the geometrical and strength characteristics of the discontinuities (e.g., roughness, wall strength and persistence). Since a rock mass is not a continuum, its behavior is dominated by such discontinuities as faults, joints and bedding planes. Also, Rock slope instability is a major hazard for human activities and o...

متن کاملDiscrete element modeling of a mining-induced rock slide
Slopes are subjected to stress redistributions during underground mining activities, and this may eventually cause deformation or landslide. This paper takes Madaling landslide in Guizhou Province, China as a case study to investigate the failure mechanism and its run-out behaviours by using discrete element method. Previous qualitative analysis indicated that the slope experienced four stages ...
متن کاملA Study of Fragmentation Processes Usinga Discrete Element Methodferenc Kun
We present a model of solids made from polygonal cells connected via beams. We calculate the macroscopic elastic moduli from the beam and cell parameters. This mod-ellisation is particularly suited for the simulation of fragmentation processes. We study the eeects of an explosion inside a circular disk and the impact of a projectile and obtain the fragment size distribution. We nd that if break...
متن کاملDiscrete element modeling of explosion-induced fracture extension in jointed rock masses
The explosion process of explosives in a borehole applies a very high pressure on its surrounding rock media. This process can initiate and propagate rock fractures, and finally, may result in the rock fragmentation. Rock fragmentation is mainly caused by the propagation of inherent pre-existing fractures of the rock mass and also from the extension of the newly formed cracks within the intact ...
