摘要
煤矿地下工程所涉及的岩石为层状的,岩石的呈层性,层状岩石结构本身的不连续、非均质性,使工程岩石的力学分析存在相当大的困难。根据工程实际的需要,层状岩石结构中的每一层岩石,均可视为均质、各向同性的弹性体。通过分析计算,用一种当量介质来代替层状岩石结构,从工程岩石力学的不同角度为研究层状岩石的当量弹性特征提供了一种简便的分析方法。
The rock of underground engineering in the colliery is bedded. Because of the bedded strata it has much difficulties in the mechanical analysis of the engineering rock. Based on the actual needs of the engineering, every stratum of layered rock structure can be regarded as the homogeneous and isotropic elastic body. But the layered rock structure itself is discontinuous and heterogenous. By analysis and calculation, the equivalent medium is found to substitute for the layered rock structure. A simple and convenient method is provided for studying mechanical behavior of layered rock at a different angle of the engineering rock mechanics.
