摘要
在总结以往岩体质量分类经验基础上 ,突出岩体的结构特征分析与研究 ,阐明了岩体质量评价的理论方法、指标体系 ,结合实例建立了一种简洁、实用的岩体质量评价体系。在这一系统中 ,突出了岩体结构面网络模拟分析在评价中对确定RQD值的重要性 ,解决了RQD值的定量分析。通过工程实践说明这一评价体系对工程建设具有重要指导意义。
Based on previous classification experience of rock mass quality,standing out analysis and research of rock mass structure characters,the theoretical method and target system of rock mass quality evaluation are expounded.Combining with example,a kind of concise and applicable rock mass quality system are established.In which the glaring point is of the importance of the rock discontinuities network simulation analysis to confirm RQD value in evaluation,the quantitative analysis of RQD value being resolved.It has been validated that this evaluation system has important instruction to project construction through engineering practice.
