    Contribución de las herramientas de teledetección y procesamiento computacional en la estimación de caídas de rocas en proyectos viales
    (Universidad EAFIT, 2024) López Rodríguez, Juan Diego; N/A
    This study analyses the use of remote sensing and computational processing tools for the quantitative estimation of rock falls in road projects. Advanced technologies such as LiDAR (Light Detection and Ranging) and digital photogrammetry allow for the generation of detailed three-dimensional models and the acquisition of high-resolution data of rock masses, significantly improving the risk assessment of slopes. These techniques overcome the limitations of traditional methods by facilitating access to hard-to-reach areas and offering greater precision in the identification of risk zones. The use of processing programs such as the Discontinuity Set Extractor (DSE) enables the identification and characterization of discontinuities in rock masses, a key factor in the analysis of slope stability. Likewise, the use of simulation software such as RocFall and RockGIS allows for the modelling of trajectories and distributions of blocks during their fall, providing essential information for the planning of mitigation measures. In particular, the implementation of the fractal fragmentation model in RockGIS represents a significant advance, improving the simulation of block behavior and, therefore, the effectiveness of protection strategies. The results indicate that the application of these technologies contributes significantly to road safety by providing detailed information that optimizes the design of containment barriers and other protection solutions. Also, the improvement towards the possible complete automation of these processes could further increase the efficiency in the management of geological risks in road projects, promoting the safety and sustainability of infrastructures.
