摘    要：在了解了国内外工程岩体分类方法研究历程的基础上，介绍了RMR系统、Q系统和BQ系统的由来与组成，重点分析了三者近年来在理论上、相关性、工程实践中的研究成果．现有的研究表明：首先，工程岩体分类方法为评估岩体质量好坏提供了捷径；其次，对于具体工程，恰当的对其进行修正，评价结果更能反映岩体的真实状态；再次，三者之间存在线性或非线性的关系，且均可用来对工程部分岩体力学参数进行估算；最后，结合应用各种数学方法，工程岩体分类方法更具合理性与操作性．

Abstract: Based on the survey of engineering rock masses evaluation methodologies, the Origin and composition of RMR, Q & BQ system are introduced. The research findings, including theoretical background, relativity and Engineering practice are analyzed. Existing researches show that: the engineering rock masses evaluation methodology provide a shortcut to evaluate rock quality; Second, for specific projects , evaluation results better reflect the true state of rock after amending; thirdly, linear or nonlinear relationship exists between them. Some rock mechanical parameters can be estimated by using each of them. Engineering rock masses evaluation methodology becomes more reasonable and feasible by applying mathematical method.
