Evaluating block shape and block volume distributions of rock faces using LiDAR and 3DEC

摘要: The use of Light Detection And Ranging (LiDAR) has expanded rapidly since 1994, when it became commercially available1. equipment mobility, as well accuracy and rate data collection, in comparison to conventional surveying stereophotogrammetric methods, have enabled the application LiDAR traditionally unrelated fields study. For instance, is currently employed applications from precise volumetric analysis open pit mines2 archaeology projects ancient ruins3. This abstract discusses a geotechnical engineering which relevance rock cuts along infrastructure corridors mines. focus this work determine distribution block size shape for given cut, each these factors crucial implications potential hazard at specific location, should failure occur. will provide geological input into rating Canadian National railroad tracks.
