- 摘要:
- 岩石的微观结构特征往往能很好反映其宏观特性，深入研究其微观结构特征对宏观特性的把控及工程建设具有重要意义。通过对常见砂、泥岩微观结构特征进行的电镜扫描实验，从微观结构特征上充分解释了其软化特性、抗冲击特性及波的传播特性等宏观力学特性方面表现的异同，并据此建议工程施工爆破中针对硬岩应注意爆破药量和爆破方式对岩石强度的影响，软岩应特别注意水的影响。同时，认为地震中硬脆岩石的大规模破坏和破碎可能与其微观结构也存在一定联系并建议进行深入研究。
- Abstract:
- The microstructure characteristic of rock frequently can reflect its macroscopic properties well, so it is very important and significant to deeply study on the microstructure characteristic of rock for controlling its macroscopic properties and engineering construction. This paper, through the electronic microscope scanning experiment to the common sandstone and mudstone, fully explain the similarities and differences of macroscopic mechanical characteristics from microstructure characteristic, such as softening, shock resistance and wave transmission, and so on. Base on this, it suggests that blast construction to hard rock ought to pay attention to the influence of blasting quantity and way to rock strength, and soft rock should especially take note of the influence of water. At the same time, it still thinks that the large scale destruction and cracking of hard brittle rock in earthquake are able to have connection with its microscopic characteristic, and suggests deeply study it.
