Summary

Characterizing and Extrapolating Rock Joint Properties in Engineering Practice. The engineering properties of a rock mass are influenced, often for the largest part, by the joints and other discontinuities within the mass. To determine and evaluate these properties it is necessary, therefore, that an acceptable method of sampling, processing and interpreting the joint population be used. Any extrapolation of these properties to other portions of the mass requires that the region to which extrapolation applies is delineated. This requires in part that certain important aspects such as regional tectonic history and joint patterns, genesis of jointing, assessment of structural controls, and so forth, are considered.

Zusammenfassung

Ingenieurgeologische Kennzeichnung und Extrapolation von Klufteigenschaften. Die technischen Eigenschaften einer Gesteinsmasse sind in den meisten Fällen durch Klüfte und andere Unstetigkeitsflächen, welche den Zusammenhang der Gesteinsmasse vermindern, beeinflußt. Zur Bestimmung und Auswertung dieser Eigenschaften ist es notwendig, eine annehmbare Methode der Untersuchung und Erklärung der Klüftung usw., also des Gefüges, zu benutzen. Eine Extrapolation dieser technischen Eigenschaften auf andere Örtlichkeiten der Gesteinsmasse setzt voraus, daß diese Regionen geologisch erschlossen sind. Dies macht es erforderlich, daß in die Beurteilung bestimmte geologische Anhaltspunkte, wie z. B. örtliche tektonische Tätigkeit, Ausbildung und Entstehung des Flächengefüges, Einfluß auf konstruktive Maßnahmen usw., mit einbezogen werden.

Résumé

Comment caractériser et extrapoler pour l’ingénieur les propriétés des roches fissurées. Les propriétés techniques d’un massif rocheux sont influencées, souvent d’une façon déterminante, par les fissures et autres discontinuités.

Pour déterminer et évaluer ces propriétés il est donc nécessaire qu’une méthode acceptable d’échantillonage, de traitement et d’interprétation de la population des fissures soit utilisée. Toute extrapolation de ces propriétés à d’autres parties du massif exige que soit délimitée la région à laquelle l’extrapolation est appliquée. Ceci demande en particulier que certains aspects importants soient considérés, tels l’histoire tectonique régionale ainsi que les réseaux de fissures, la genèse de la fissuration, la détermination des relations entre tectonique et structure, etc.
