摘要
岩体质量分级是定量化描述岩体结构复杂性的手段,为岩体工程稳定分析与合理利用提供依据。系统介绍了基于ItasCAD三维地质模型的岩体质量分级方法和实现过程,并以镇安抽水蓄能电站大型地下厂房为研究对象,运用BQ、RMR和水电HC分类对围岩质量进行分析评价。结果表明,虽然各岩体质量评价方法的侧重点有所不同,但ItasCAD能将这3种方法综合使用,起到相互借鉴与补充的作用,进而更加真实地反映岩体的质量条件,可为地下工程岩体质量分析与评价提供借鉴。
Rock mass quality classification is a means to quantitatively describe the complexity of rock structures,which provides a basis for the stability analysis and rational utilization of rock engineering.This study introduces the method and process of rock mass quality classification based on ItasCAD 3 D geological modeling,and taking the underground powerhouse of Zhen’an Pumped-storage Power Station as an object,the quality of surrounding rock is estimated using BQ,RMR and HC classifications.The results show that,although the emphases of each evaluation method are different,the ItasCAD can comprehensively use these three methods,learn from and supplement each other,to reflect the quality of rock mass.The research provides a reference for the evaluation of rock mass quality in underground engineering.
