Support design for jointed rock masses can be approached in several ways. When designing support systems for these conditions, the potential block sizes and likelihood of occurrence should be considered. This paper outlines an approach whereby probabilistic ...

In nearly 240 years 53 landslides have occurred along the Quebec City Promontory, causing 88 fatalities mainly by rockfalls. In October 2004 a rockfall reached the road close to the 1889 rockfall event which killed 35 people and injured 30 others. Using a ...

Since 1857, several hundred rockfalls, rockslides, and debris flows have been observed in Yosemite National Park. At 12:45 a.m. on December 26, 2003, a severe winter storm triggered a rockfall west of Glacier Point in Yosemite Valley. Rock debris moved quickly ...

The analysis of structure using joint set statistics is well known. Other data such as the position of discontinuities and the contacts between rock mass units cannot be easily incorporated in simple statistical analysis based on orientation alone. Algorithms ...

A case study is presented that relates statistical descriptions of joint sets to the distribution of local wedge failures along the crest of a catch bench at the Yellowstone Talc Mine. The fracture sets and bench width were mapped by teams of geological engineering ...

<p>This paper applies numerical limit analysis to evaluate the bearing capacity of strip footings on an anisotropic, homogenous material. While solutions exist for footings on jointed rock [Proceedings of the Third International Conference on Computational ...

One of the valuable services a forest in the Alps provides is protection against natural hazards such as rockfall. Adequate management of a mountain forest that protects downslope areas against impacts of rockfall requires insight into the dynamics of the ...

<p>About 22 mio m³ of rock fell from a cliff near the village of Randa (10 km north of Zermatt, Switzerland) on 18 April 1991. A second retrogressive rockslide of about 7 miom³ followed on 9 May 1991. At present, a rock mass situated ...

This report summarizes much of the material presented at the workshop and provides an extensive list of selected references pertaining to geochronology and tectonics of the Colorado Plateau to facilitate further research.
