Abstract
Mechanical properties of discontinuities are different from those of a whole rock. In particular, shear strength of a discontinuity is closely related to its morphological characteristics. Study on mechanical behavior and its failure mechanism of jointed rocks under shear stresses is of great theoretical significance. This paper presents a fundamental research on mechanical properties of the regular jugged discontinuity under various normal stresses. The strength and roughness of discontinuity under shear stress are investigated by analysis of the shear test data. An empirical formula between slope ratio and roughness coefficient of discontinuity are proposed to calculate shear stiffness, and an empirical formula is finally established to evaluate shear strength of discontinuity.
Kurzfassung
Insbesondere ist Scherfestigkeit einer Diskontinuität eng mit ihrer morphologischen Merkmale. Studie über mechanische Verhalten und sein Scheitern Mechanismus der verbunden Felsen unter Schubspannungen ist von großer theoretischer Bedeutung. Dieses Papier stellt eine Grundlagenforschung auf die mechanischen Eigenschaften des regelmäßige zahnforme Diskontinuität unter verschiedenen Normalspannungen. Die Stärke und Rauhigkeit der Diskontinuität unter Scherbeanspruchung sind durch eine Analyse der Scher-Testdaten untersucht. Um Schubsteifigkeit zu berechnen, eine empirische Formel zwischen Hang-Verhältnis und Rauheit der Diskontinuität werden vorgeschlagen. Und eine empirische Formel ist endlich gegründet, um Scherfestigkeit der Diskontinuität zu bewerten.
