Methodical design for stability assessments of permafrost-affected high-mountain rock walls


Fischer, L; Huggel, C (2008). Methodical design for stability assessments of permafrost-affected high-mountain rock walls. In: 9th International Conference on Permafrost, Fairbanks, Alaska, 29 June 2008 - 3 July 2008, 439-444.

Abstract

Slope stability of steep rock walls in glacierised and permafrost-affected high-mountain regions is influenced by a number of different factors and processes. For an integral assessment of slope stability, a better understanding of the predisposing factors is particularly important, especially in view of rapid climate-related changes. This study introduces a methodical design that includes suitable methods and techniques for investigations of different predisposing factors in high-mountain rock walls. Current state-of-the-art techniques are reviewed, and their potential application for in situ and remote studies is assessed. A comprehensive array of analyses and modeling tools is presented, including data-acquisition methods and subsequent stability analyses. Based on two case studies of recent slope instabilities in the European Alps, the effective application and coupling of measurements, analyses, and modeling methods are shown.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
