Abstract
As is known, there are many fractures in rock slope, and these fractures are often the cause of failure. Especially, the mechanism of sliding failure depends on fractures in rock slope. In this paper, Three-dimensional numerical simulation for sliding failure by distinct element method are carried out. In relation to this simulation, the interparticle bonding force can be tried to be expressed by bonding theory. It is tried to be simulated an actual sliding failure of rock slope. As the results of this simulation, it is recognized that this simulation can be expressed on this sliding failure phenomena. Moreover, the process of sliding failure can be visualized.
