Abstract
As is known, there are many fractures in rock slope, and these fractures are often the cause of failure. Especially, the mechanism of toppling failure depends on fractures in rock slope. In this paper, two-dimensional simulation analysis and visualization for toppling failure of rock slope by distinct element method are carried out. In related with this simulation, the tensile stress of rock mass can be tried to be expressed by bonding theory. The rock slope model with this analysis can be freely setting the slope shape and the location of joints. Using this analytical model, it is tried to be simulated an actual toppling failure of rock slope. As the results of this analysis, it is recognized that this simulation can be expressed on this toppling failure phenomena. Moreover, the process of toppling failure can be visualized.
