in the past, rock slope stability analysis were performed either graphically or using a hand-held calculator, but nowadays there are variety of slope stability analysis which can be used according to the field condition and potential failure mode. in 2-d analysis, effect of convex and concave walls are neglected, however concave slopes are believed to be more stable than straight walls due to t...

Data on discontinuities are always necessary for design, characterization and analysis of rock structures. The time honored method of manual measurements with Brunton compass is both time consuming and often inconvenient given issues such as restricted access to measurement areas, introduction of erroneous data due to sampling difficulties and human bias, considerable safety risks since measure...

The city bypass tunnel of Waidhofen an der Ybbs (Austria) is situated in an intricate geological-geotechnical complex consisting of soil, hard soil, weak rock and solid rock. Marls and marly limestone (Waidhofener formation) predominate followed by tectonic breccia of the Alpine cliff zone, which is a tectonic melange zone. Materials of this kind universally have isolated interior blocks embedd...

Rock walls and talus slopes, which are the most common features of high-mountain relief, have been researched for many years. Geomorphologists taken particular interest in debris flows, play a major role development slopes. This paper presents results first lichenometric dating flows on southern slopes Tatra Mountains. The greatest flow activity took place Little Ice Age last two decades.

ABSTRACT: A number of civil engineering projects which include river valley projects, transportation projects and metro rail projects are under construction in India. Various structures, such as underground openings, powerhouse caverns, metro tunnels, dam foundations and slopes are increasingly located in/on rock formations. The rock in its natural state is a very complex material especially wh...

This paper describes the interim results of a study to characterize discontinuous rock masses using 3D laser scanning data. One of the main advantages of this method is that now an unbiased, rapid and accurate discontinuity analysis can be done. With 3D laser scanning it is now also possible to measure rock faces whose access is restricted or rock slopes along highways or railway lines where wo...
