摘要:

以厄瓜多尔CCS水电站地下厂房为研究对象,在综合分析RMR法、Q系统法及水电HC法3种围岩分类的特点及适用范围的基础上,采用3种分类方法对CCS水电站地下厂房洞群围岩进行了分类,并对分类结果进行了对比分析,以RMR法、Q系统法和水电HC法分类结果为基础,采用专家经验对地下厂房围岩进行综合评判,得出各洞段的最终围岩等级。研究结果表明: 3种方法分类结果相差较小,分类结果较为可靠;水电HC法以往在国内应用较多,同样适用于国外工程,值得进一步向国际工程推广应用。

Abstract:

The characteristics and application scopes of RMR method, Q system and HC method are analyzed. The surrounding rock of the underground powerhouse of CCS hydropower station in Ecuador is classified by RMR method, Q system and HC method respectively, and the classification results are compared. Expert experience is used to make comprehensive evaluation on the surrounding rock of the underground powerhouse, which has already been classified on basis of RMR method, Q system and HC method respectively, and the final classification of the surrounding rock of each section of the underground powerhouse is obtained. The study result shows that there is little difference among the classification results of these three methods and that HC method, which has been widely used in China, is applicable to projects in foreign countries and is worth to be further promoted to projects abroad.

Key words: CCS hydropower station, underground powerhouse, surrounding rock classification, RMR method, Q system, HC method
