摘    要:为研究岩石材料的时间效应,利用CSS-1950型岩石流变试验机,分别对绿泥石片岩和云母石英片岩进行压缩蠕变试验.基于试验结果,分析了蠕变对岩石荷载-变形关系的影响规律,研究了轴向变形随时间变化的基本趋势,论述了两种片岩在蠕变过程中的变形特性,并阐明了岩石的蠕变破裂形式及损伤机制.结果表明:岩石的蠕变特性与岩性、初始损伤密切相关;云母石英片岩的蠕变性好于绿泥石片岩.

关 键 词:岩石力学  绿泥石片岩  云母石英片岩  流变试验  蠕变

Abstract:Compressive rheological experiments were carried out on chlorite-schist and sericite-schist respectively to study their time-effect by using rock rheological test equipment CSS-1950.The influence law of creep on relation between load-deformation characteristics and rheology of rock were analyzed based on the experimental results,and the basic tendency of axial strains with the time was investigated. The deformation properties of chlorite-schist and sericite-schist during the course of rheology were discusse...
Keywords:rock mechanics  chlorite-schist  sericite-schist  rheological experiment  creep
