【摘要】 CSM R岩体质量分级方法是我国在RM R-SM R体系的基础上,引入高度修正系数和结构面条件修正系数而成,本文在阐述CSM R法应用的基础上,综合国内外对其修正的意见,提出修正的CSM R法,并通过大量的工程实例对修正的CSM R法进行校验,并回归出修正的CSM R法与RM R法的关系函数,结果表明修正后的岩体质量分级方法更适用于工程实际,可进一步推广。更多还原

【Abstract】 The CSMR classification method of rock mass was obtained by introducing the height correction coefficient and the jiont correction coefficient based on the RMR-SMR system.The paper adopted the opinions from domestic and abroad while application of CSMR method to engineering practice and suggested a modified CSMR method.Application of the modified CSMR method to engineering practice and got it verified and obtained the modified function between CSMR and RMR methods.The application of the new CSMR classification method of rock mass showed that the modified classification method of rock mass is suitable for the actual project,so that the evaluation method can be popularizedfurther.更多还原
