摘要
本文对大量的岩石断口进行了扫描电镜分析和光学显微镜观察,探讨了岩石断裂的微观机理。用Cottrell位错塞积模型分析了岩石脆断裂纹的产生和扩展,并由此解释了一些宏观现象。
A great number of fractures of different types of rock are examined by electrical scanning and optical microscope to investigate micro-mechanism of rock fracture. Initiation and propagation of cracks in brittle rock are analyzed by using model of Cottrell's dislocation pile-ups based on which macro-phenomena are explained.
