Summary

A Portable Shear Box for Testing Rock Joints

The authors describe their early work on the development and operation of a portable shear box for testing rock joints. Experiences with sampling, roughness assessments, testing techniques and test interpretation using the shear box are outlined. More recent modifications and developments are also discussed, and a number of test results are presented.

Zusammenfassung

Ein transportables Schergerät zur Untersuchung von Gesteinsklüften

Die Verfasser schildern ihre Arbeit an der Entwicklung und Verwendung eines transportablen Schergerätes zur Untersuchung von Gesteinsklüften. Es werden die Erfahrungen bei der Probengewinnung, mit der Abschätzung der Rauhigkeit, mit den Untersuchungsverfahren und der Versuchsauswertung während des Einsatzes der Scherbüchse besprochen. Außerdem werden neuere Abänderungen und Entwicklungen des Gerätes erörtert und mehrere Versuchsergebnisse vorgelegt.

Résumé

Une boîte de cisaillement portative servant aux essais des joints rocheux

Les auteurs donnent une description de leur travaux lors du développement et de l'utilisation d'un appareil de cisaillement destiné à l'examen de joints des roches. Ils communiquent leurs expériences concernant les prélèvements d'éprouvettes, l'estimation de les méthodes d'essai et l'exploitation des résultats d'essai à l'aide de l'appareil de cisaillement décrit. D'autre part on décrit les modifications et améliorations récentes de l'appareil et on présente les résultats d'essai.
