摘要
This research refers to the analysis and prediction of rockfall risk,whose objective is to determine the results of the validation of the model and application of modeling in the Rocfall Software,in this way to prepare the map of risk areas.Likewise,the general problem was identified:What are the results of the analysis and prediction of risks from rockfall in the city of Huancavelica?To respond to the problem posed,the following steps were carried out:obtaining field information with Drone equipment and using photogrammetric processes the topography of the study area was obtained,identification of unstable areas,trajectories,traces of the previously occurred landslides and five geomechanical stations.The specific weight of eight rock samples in the laboratory of the National University of Huancavelica was also calculated,which served to obtain the weight of the large-scale rock blocks.In addition,the normal and tangential restitution coefficients were calibrated,that is,field trials.Once the data were obtained,modeling was carried out by applying the Rocfall software,whose results of ten trajectories were:final distance reached,bounce height,kinetic energy and translational speed.With these values,risk maps have been prepared,taking into account the areas of housing vulnerability in the city of Huancavelica.Finally,it is proposed to mitigate these risks of rockfall,with dynamic barriers,which is important for the security of housing in the analysis sectors.
