Rock mass classification systems provide more insight into rock mass conditions. Therefore, rock mass classification systems, mainly used in engineering applications is an empirical design method. RMR, Q, and M-RMR classification systems take into account 28 geotechnical parameters. To characterize rock mass behavior for each of geotechnical intervals, 28 geotechnical parameter must be described. The number of data gathered for all boreholes increases exponentially. As a result, evaluation of these data and also reporting is quite difficult and time-consuming procedure. In order to overcome these difficulties, ROCKMASS v2.0 has been developed, which is only based on RMR, Q and M-RMR classification systems. The geotechnical parameters obtained from each of geotechnical interval can be easily recorded by ROCMASS v2.0. After recording all the data for borehole, the needed log reports and evaluations for investigated borehole are given by ROCKMASS v2.0.
