The Micro-Mechanism Analysis on Rock Creep Damage

Abstract:

Rock creep is a hot topic and key point in engineering geology. Based on renormalization group theory, the rock creep instability of micro-mechanism can be described as follow: with the expanding and interaction of micro-cracks and the main fault forms, which leads to failure. Comparing with the similarity of rock creep and rock compression process, and combining results of rock creep process, it is shown that there a distinct pertinence between different stages of rock creep. The relationship characteristics of different evolutionary stages can be used to provide scientific foundation for rock creep.
