Your single point of reference for all your Geotechnical Inquiries
The program classifies rock masses using both the Bieniawski and the Barton methods, making it thus possible to compare the results that can be obtained with the two most frequently used classification methods.
The Bieniawski classification (RMR Index) evaluates different parameters to which a numerical coefficient is assigned.
The sum of these coefficients determine the Rock Mass Rating class the rock mass belongs to.
At the end of the analysis, the program calculates the GSI index (Geological Strength Index) using the relation GSI = RMR89 - 5, Where RMR89 is evaluated by placing the rating of the parameter over a presence of water equal to 15, and the correction parameter over the direction of the joints equal to zero.
The classification proposed by Barton (Q Index) is based on the determination of the Q index which denotes the quality of the rock. The calculation results are proposed in tabular form that can be viewed and printed within the program or can be imported into any word processor for a later re-elaboration stage.u
