Geophysical detection and structural characterization of discontinuities in rock slopes
The stability of a potentially unstable rock mass strongly depends on the discontinuity pattern and the face topography. Basic geological analysis could provide useful structural information but suffers from the lack of information on discontinuities at depth. Of major importance is the persistence of discontinuities inside the mass. Several geophysical methods (seismic, electric and electromag...
متن کاملAutomated sliding susceptibility mapping of rock slopes
We present a suite of extensions for ARCVIEW GISTM (ESRI) that allows to map the spatial distribution of first-order mechanical slope-properties in hard rock terrain, e.g. for large slope areas like water reservoir slopes. Besides digital elevation data, this expert-system includes regional continuous grid-based data on geological structures that might act as potential sliding or cutoff planes ...
متن کاملRock Slopes from Mechanics to Decision Making
Rock slope instabilities are discussed in the context of decision making for risk assessment and management. Hence, the state of the slope and possible failure mechanism need to be defined first. This is done with geometrical and mechanical models for which recent developments are presented. This leads with appropriate consideration of uncertainties to risk determination and to the description ...
متن کاملStability of rock slopes in Valles Marineris, Mars
[1] New slope measurements from the Mars Orbiter Laser Altimeter (MOLA), in conjunction with the Rock Mass Rating system (RMR), permit inversions of slope height and angle from wallrock and interior deposits within Valles Marineris troughs for strength and lithology. Wallrock (50 < RMR < 65) is stronger than interior deposits (30 < RMR < 55). These values are consistent with layered igneous roc...
متن کاملFlexural Toppling Failure in Rock Slopes: From Theory to Applications
Toppling failure is one of the most common modes of failure of rock slopes in layered rock strata. Flexural toppling is one of the well-known modes of the failure. This type of failure occurs due to bending stress. In this article, a brief yet comprehensive review of toppling failure is presented. Firstly, the conditions and general mechanism of the failure are described. Then, experimental, th...
