Paper presented at the 1st Canada - U.S. Rock Mechanics Symposium, May 27–31, 2007
Paper Number: ARMA-07-155
... ABSTRACT ABSTRACT: Forecasting potential rock slope failure in open pit mines is necessary to maintain safety and mine productivity. Laboratory testing of rain induced landslides in Japan over 20 years ago led to an inversevelocity approach for estimating the time of a slope failure. This...

... Mountains 23 km northwest of the town of Grande Cache in western Alberta (Fig. 1). This paper deals with a ground-based photogrammetry survey conducted immediately before and after a footwall slope failure in the No. 12S B2 pit, supplemented with movement histories of prisms placed on the slope. The slope...

... to model precisely the physical process involved in slope failure. The methods we do use to describe the anisotropic strength of a closely jointed rock mass and model its deformation are highly subjective and experiential. Consequently, different operators not infrequently provide quite different...

... ABSTRACT ABSTRACT: The slope failure of debris flow fans is distinct from common rock and soil slope failures due to the unique geotechnical features of debris flow sediment. This type of failure was not comprehensively and systematically studied in the past. In our recent research, based on...

... ABSTRACT ABSTRACT: This paper presents a new geomechanical classification for slopes, the SFi (Slope Failure Index) system based on the detailed examination of more than 700 road cuts. The SFi system adopts different evaluation codes based on the different geotechnical conditions. In the SFi...

Combined with models of the temporal nature of slope failure evolution, for example first time failure due to brittle crack nucleation and coalescence, these data have the...
