摘　　要：岩体分类在岩体的变形、强度以及岩石工程稳定性评估中有着重要的作用,尤其是在工程的经验设计和数值模拟中,是最基本的依据。通过对当前常用岩体分类方法 RQD、Q、RMR、RMi、GSI、RCR和N法的分析,讨论了各种分类方法在实际应用中存在的问题,给出了一些各种分析方法之间的关系式,从而便于实际的应用。Rock mass classification plays an important role in estimating the strength and deformability of rock masses and in assessing the stability of rock engineering,which is essential in engineering empirical design and numerical analyses. The methods of RQD,Q,RMR,RMi,GSI,RCR and N of rock mass classification are analyzed,the systems discussed and some problems in the engineering application pointed out. A series of correlations were established between the systems. The relationships were then compared with those reported in the literature.
