Dinámica del volteo de bloques en taludes rocosos

This document presents the dynamic analysis of a toppling's process in a rock slope. For this, the program Toppling UN was created, which is capable of reproducing the movement of a block system. The program was formulated based on the Discrete Element Method (DEM). This method is a numerical procedure that allows to study the movement of a system of particles, in this case rigid blocks, from the calculation of the interaction between blocks. The shock forces between blocks are simulated by rheological units, while the movement is calculated through a set of equations that arise from Newton's second Law. The program is applied in a rocky slope susceptible to toppling. As a result, is obtained the forces, the velocity and the displacement of each blocks in the slope. With this information, the dynamic behavior of the slope for di erent values in the friction angle of the blocks is analyzed. It can be seen that, although a slope is established, it is possible that a series of local movements may occur due to the individual instability of the blocks.
