摘要
RMR classification in the design in tunnel is that classification rock has been used with determination according to the rock jewel mode of grade extensively. However, the method can only be used the judgement classification rock of experiences of the available hayeoyaman of RMR classified variables in view of habitat conditions and by technician. All RMR for considering evaluation factor, when utilizing RMR petrographic classifications in the design phase, this is not feasible. ;Therefore design, which makes full use of the unit of only quantity to analyze, will carry out confirming that potential RMR of classification determined. The highly relevant coefficient of data or RQD of rock strength is between RMR values, when seeing existing batu intensity and RQD classification is the key factor for rock category. When being classified using discriminant analysis, batu rock mass classification and discriminant analysis be performed by existing RMR petrographic classifications only consider the intensity of two variable as an independent variable, 74.8%, when use discriminant analysis as an independent variable RQD 74.When 3% accuracy RMR classification may be vibrated. 82.5% accuracy may RMR petrographic classifications when considering to have the discriminant analysis of rock strength and RQD. The center of design procedure is thrown, and is brought by the entire elements of RMR of the existing case study from the design phase, it is contemplated that 40.3% horizontal sujunim it will be only rock strength and RQD is enough RMR petrographic classifications.
