Discussion on the paper entitled “Quantitative assessments of the correlations between rock mass rating (RMR) and geological strength index (GSI)” by Qi Zhang, Xianbin Huang, Hehua Zhu and Jianchun Li, Published in Tunnelling and Underground Space Technology (2019) 83:73–81

Abstract The rationality of formulas 22, 27 and 28 in the paper by Qi Zhang et al. (2019) were discussed due to its derivation process. The reason for this irrationality was analyzed in detail and the relationship between RMR89 and RMR14 under the condition of considering only discontinuities of rock mass was extracted. On this basis, a more reasonable formula has been proposed to replace formula 22. And another new relationship between R M R 89 and GSI considering strength of intact rock and groundwater has also been put forward. The case study shows that the two formulas proposed in this discussion are applicable.

对张齐、黄贤斌、朱鹤华和李建春发表的题为“岩体等级(RMR)与地质强度指数(GSI)之间相关性的定量评估”论文的讨论,发表于隧道与地下空间技术(2019)83 :73–81

摘要 齐张等人论文中公式22、27、28的合理性。(2019)因其推导过程而被讨论。详细分析了这种不合理性的原因,提取了仅考虑岩体不连续性条件下RMR89与RMR14的关系。在此基础上,提出了一个更合理的公式来代替公式22,并提出了另一种考虑完整岩石强度和地下水强度的RMR 89与GSI之间的新关系。案例研究表明,本次讨论中提出的两个公式是适用的。
