On November 25, 2012, a rockslide occurred along the Canadian National Railway tracks, approximately 150 km northeast of Vancouver, Canada. The volume of the slide was approximately 53,000 m3. It caused four days of service disruption and the collapse of a rock shed protecting the tracks. This paper studies the triggering factors and the failure mechanism based on a combination of airborne and terrestrial LiDAR data, site investigation and discrete fracture network (DFN) modeling. This work provided input parameters for subsequent runout analysis and design of a railway protection structure (rock shed).
