基于现场对岩体结构面的统计,应用蒙特卡罗法进行岩体结构面网络模拟,得到不同块度标准下岩体的RQD值。结合现场岩体出露条件及室内岩块力学试验结果,应用RMR和Q值分类法对岩体质量进行评价,通过Hock-Brown经验方法估算岩体强度参数,并提出了适合研究区的岩体强度参数建议值。 Based on the statistics of the rock mass structural plane in the field, the Monte Carlo method was used to simulate the rock mass structural plane network, and the RQD values ​​of the rock mass under different block standards were obtained. According to the rock outcropping conditions and the mechanical test results of indoor rock mass, the rock mass quality is evaluated by RMR and Q value classification method, the rock mass strength parameters are estimated by Hock-Brown empirical method, and the rock mass suitable for the study area is proposed Strength parameter suggested value.
