Abstract
Investigation of rockfalls motion to estimate affected area and hazard effects is very important. The importance of studying of such phenomena is determined by a number of reasons, among them the danger to human life in the relevant territories. Mathematical and computer modeling methods allow to estimate the influence of the slope geometry (the angle of the slope and the height of the slope) on the distance of the run after rockfalls. This paper presents the results of modeling of the rocks motion along the slope that is attached to a horizontal section. We obtained the results of modeling using the discrete element method for different values of the angle of the slope and the height of the slope. The results of modeling were compared with the experimental data. In general, the model, based on the discrete element method, satisfactorily describes the experiments of the falling dolomite rock in the investigated range of the angle of the slope and the height of the slope. The results of calculations of the distance of the run after rockfalls are overestimated in comparison with the experimental data. The distance of the run after rockfall increases almost linearly with the angle of the slope. The difference between the results of calculations and experiments increases with the increasing of the height of the slope. The difference also increases with the increasing of the angle of the slope in the case of the high value of the height of the slope. We concluded, that the model, based on the discrete element method, can be used to simulate rockfalls.
