Abstract
This paper reports an improved constitutive model for the shear creep behaviour of offwhite marbles which are selected from slope or underground cavern and contain greenschist's weak structural planes. The shear creep behaviour of the samples is characterized by rheological tests. Based on the experimental measurements on mechanical properties under different normal stress conditions, an improved model is proposed to analyze the experimental results. It is demonstrated from a further discussion that such model can reflect the non-linear creep characteristics of structural planes, and especially, it is suitable for description of the viscoelastic and viscoplastic deformation behaviour of structural planes.
Kurzfassung
In dem vorliegenden Beitrag wird über ein verbessertes konstitutives Modell für das Scherkriechverhalten von cremefarbenem Marmor, der von Hängen oder Untergrundaushöhlungen stammen und der schwache Strukturebenen aus Grünschiefer enthalten. Das Scherkriechverhalten der Proben wurde mittels rheologischer Versuche charakterisiert. Basierend auf den experimentellen Messungen der mechanischen Eigenschaften unter verschiedenen Normalspannungsbedingungen wird ein verbessertes Modell vorgeschlagen, um die experimentellen Resultate zu analysieren. Anhand einer früheren Diskussion hat sich gezeigt, dass ein solches Modell die nichtlinearen Kriechcharakteristika von Strukturebenen reflektiert und insbesondere, dass es geeignet ist, um das vsikoelastische und das viskoplastische Verformungsverhalten von Strukturebenen zu beschreiben.
