| Abstract | The McAuley Creek Landslide is a 6 Mm3 rock slope failure that occurred in south-central British Columbia (Canada) in late May-early June 2002. The Geological Strength Index (GSI) was used to
characterize the quality of the overall rock mass and its reduced (damaged) quality near tectonic structures and alteration zones. Potential failure mechanisms were investigated using kinematic analysis and three-dimensional distinct element codes.
Of the 6 Mm3 of material involved in the slope failure approximately 5 Mm3 was deposited immediately below the source area against the opposite valley wall with the remaining 1 Mm3 traveling an additional 1.6 km downstream. The run-out behaviour was
investigated using a three-dimensional dynamic analysis code. |
