Quantifying discontinuity orientation and persistence on high mountain rock slopes and large landslides using terrestrial remote sensing techniques
discontinuity orientation high mountain rock slopes remote sensing techniques
2009/12/16
This paper describes experience gained in the application of terrestrial digital photogrammetry and terrestrial laser scanning for the characterization of the structure of high mountain rock slopes an...
Variogram maps from LiDAR data as fingerprints of surface morphology on scree slopes
Variogram maps LiDAR data fingerprints surface morphology scree slopes
2009/12/16
Herein, an aerial LiDAR topographic dataset is analysed and interpolated by means of geostatistical techniques in order to examine the morphology of a scree slope area in the Eastern Italian Alps. The...
Terraces cover large areas along the flanks of many alpine and prealpine valleys. Soil slips and soil slips-debris flows are recurrent phenomena along terraced slopes. These landslides cause damages t...
Half-scale experimental study of rockfall impacts on sandy slopes
Half-scale experimental study rockfall impacts sandy slopes
2009/12/10
In the framework of rockfall trajectory modelling, the bouncing phenomenon occurring when a rock block impacts with the slope surface is the most difficult to predict, owing to its complexity and its ...
An experimental study of particle-driven gravity currents on steep slopes with entrainment of particles
particle-driven gravity currents steep slopes entrainment of particles
2009/12/9
Results of laboratory experiments are presented in which a finite suspension of sawdust particles was released instantaneously into a rectangular channel immersed in a water tank. Two kinds of gravity...
Snow fences on slopes at high wind speed: physical modelling in the CSTB cold wind tunnel
Snow fences high wind speed physical modelling the CSTB cold wind tunnel
2009/12/9
In order to determine the effect of steep slopes on snowdrift generated by snow fences, we have conducted physical modeling experiments in the CSTB (Centre Scientifique et Technique du Bâtiment)...
Risk-based stabilization planning for soil cut slopes
Risk-based stabilization planning soil cut slopes
2009/12/8
Risk-based slope stabilization planning integrates the failure probability and the failure consequence systematically and shows promise for use in the practice. This paper attempts to develop a risk-b...

Improvements of safety conditions of unstable rock slopes through the use of explosives
safety conditions unstable rock slopes the use of explosives
2009/12/30
The paper discusses operations aimed at creating a safer natural or man made rock slope by artificially inducing the displacement of unstable elements by blasting. A detailed analysis of the problems ...
Development of a ground displacement measurement method for failed slopes at the toes of landslides
ground displacement measurement method failed slopes toes of landslides
2010/1/27
Sediments produced by a slope failure of the toe of a landslide are assumed to prevent the spread of the failure. Thus, sediment removal is an emergency measure that must be done safely while the slop...
Softening and instability of natural slopes in highly fissured plastic clay shales
Softening instability natural slopes highly fissured plastic clay shales
2009/12/29
Softening is often considered to be the main cause of first-time slides in OC clay, but so far the mechanics of softening has not been satisfactorily explained. Bearing on laboratory data and field ob...
Real-size experiments and 3-D simulation of rockfall on forested and non-forested slopes
Real-size experiments 3-D simulation rockfall forested and non-forested slopes
2009/12/29
Only a few rockfall simulation models take into account the mitigating effect of existing forest cover. The objective of our study was to improve the generic rockfall simulation model RockyFor, which ...
