Cartographie semi-automatisée des chutes de pierres le long d'infrastructures linéaires
|Abstract:||The detailed characterization of large area is a challenging task because time and resources are frequently limited. This Master’s thesis is part of the ParaChute research project. The aim of this project is to develop a rockfall susceptibility rating system along linear infrastructures. A partially automated method has been developed to facilitate field works planning while optimizing time and resources. It is mainly based on 3D rockfall simulations carried out systematically and efficiently on every rock slopes located nearby the infrastructure to help identify potential hazardous natural cliffs. Automation tools were developed to allow the realization of simulations over large area. The proposed method also uses the software Rockyfor3D and only requires surface elevation model obtained from airborne LiDAR survey as input data. However, other data, such as orthophotos, were used for calibration. The method was applied along the ArcelorMittal Infrastructures Canada railway. The covered zone starts near Port-Cartier (Québec) and extends 260 km north along the ArcelorMittal Infrastructures Canada railway up to the Groulx Mountains. In this Master’s thesis, a partially automated method that helps to choose on which areas to focus field work by telling if there is a possibility for a block to reach the linear infrastructure is detailed.|
