An historical, geomechanical and probabilistic approach to rock-fall hazard assessment
rock-fall hazard assessment an historical, geomechanical and probabilistic approach
2009/12/10
A new method (HGP for Historical, Geomechanical and Probabilistic) is proposed to estimate the failure probability of potentially unstable rock masses in a homogenous area, as a function of time. Ana...
Probabilistic approach to rock fall hazard assessment: potential of historical data analysis
Probabilistic approach hazard assessment historical data analysis
2009/12/9
In agreement with previous studies, this suggests, that the b value is not dependant on the geological settings. Regarding the rate of rock fall activity, determined as the number of rock fall events ...
Micro-seismic precursory cracks prior to rock-fall on coastal chalk cliffs:a case study at Mesnil-Val,Normandie,NW France
Micro-seismic precursory cracks rock-fall coastal chalk cliffs
2009/12/8
Erosion of rock cliffs has been considered to be relatively unpredictable. This perceived stochastic nature of the erosional processes often occurs through collapses along fractures in the rock-mass. ...
Considerations on Swiss methodologies for rock fall hazard mapping based on trajectory modelling
Swiss methodologies rock fall hazard mapping trajectory modelling
2009/12/8
Rock fall hazard assessment and hazard mapping are essential for the risk management of vulnerable areas. This paper analyses some issues concerning fragmental rock fall hazard mapping methodologies. ...
Numerical simulation of debris flows triggered from the Strug rock fall source area,W Slovenia
Numerical simulation debris flows Strug rock fall source area
2009/12/29
The Strug landslide was triggered in December 2001 as a rockslide, followed by a rock fall. In 2002, about 20 debris flows were registered in the Kosec village; they were initiated in the Strug rock f...
Using a laser measurement system for monitoring morphological changes on the Strug rock fall,Slovenia
laser measurement system morphological changes Strug rock fall
2009/12/25
A medium-ranged high performance handheld reflectorless laser measurement system, was used for a morphological survey on the Strug rock fall in W Slovenia in the period from August 2003 to August 2004...
