A COMPUTER APPLICATION MODULE EVALUATING ROCK MASS QUALITY RATING

The Rock Mass Quality Rating (RMQR) classification system has become one of the attractive rock classification systems today, due to its up-to-date and user-friendly nature. When the system was proposed in 2014, correlations were also provided for finding out the equivalents of the rock quality score obtained from the RMQR system in other frequently used rock classification systems like RMR and Q. This option has contributed the system easier to use for researchers and engineers. The RMQR system classifies the rock environment according to 6 basic parameters. The ranges given for these parameters and based on the scoring are the issues that should be carefully considered in determining the rock class. In this study, the ranges used to calculate the RMQR system and the relations that digitize them have been converted into MATLAB functions. Based on these converted functions, a Windows-based computer application module has been coded that basically calculates the RMQR, determines the class of the rock and gives its equivalents in the RMR and Q systems. This module, called “RMQRCalc”, is an open source software by using the MATLAB graphical user interface, and is considered as a basic module that is a part of rock classification library to be made in this regard.
