Journal ArticleDOI
Classifications of properties influencing the drillability of rocks, based on the NTNU/SINTEF test method
TL;DR: The demand for representative rock property parameters related to planning of underground excavations is increasing, as these parameters constitute fundamental input for obtaining the most reliable underground excavation plans as discussed by the authors, as well as providing a more reliable underground exploration model.
Journal ArticleDOI
Examples of multiple rock-slope collapses from Kofels (Otz valley, Austria) and western Norway
Reginald L. Hermanns,Lars Harald Blikra,M. Naumann,Bjørn Nilsen,Krishna Kanta Panthi,D. Stromeyer,Oddvar Longva +6 more
TL;DR: In this paper, the effects of large massive rock-slope failures on subsequent slope stability are described, and the authors show that failure increases the probability of further collapses. But they do not consider the impact of these failures on the stability of the slope.
Journal ArticleDOI
Uncertainty analysis of tunnel squeezing for two tunnel cases from Nepal Himalaya
TL;DR: In this paper, a probabilistic approach to uncertainty analysis that focuses on the effect of the variations in each input parameter of tunnel squeezing is used for analyzing and predicting the extent of tunnel tunnel squeezing for two tunnel cases in Nepal; Kaligandaki “A” (completed) and Middle Marsyangdi (under construction).
Journal ArticleDOI
New trends in rock slope stability analyses
TL;DR: In this article, alternative approaches to stability analyses including the traditional deterministic principle, the so-called partial factor principle and the probabilistic approach which assesses the probability of failure rather than the factor of safety are discussed.
Journal ArticleDOI
Probabilistic rock slope stability analysis for Himalayan conditions
Shubh Pathak,Bjørn Nilsen +1 more
TL;DR: In this article, the authors estimate the value of variable input parameters (groundwater pressure, active friction angle and seismic acceleration) and study their sensitivity in rock slope stability analyses for Himalayan conditions.
