heal.abstract	Αντικείμενο της παρούσας διπλωματικής εργασίας, είναι η μελέτη και παρουσίαση των συστημάτων ταξινόμησης της βραχομάζας, με τελικό στόχο την εύρεση, μελέτη, επαλήθευση και εν τέλει παρουσίαση μιας ήδη υπάρχουσας μεθόδου η οποία συνδυάζει τα ευρέως γνωστότερα και χρησιμοποιούμενα εκ των κριτηρίων αυτών.	el
heal.abstract	The purpose of this thesis is the study and presentation of the rock mass classification systems. The purpose for which each one developed and their various corrections over time are examined throughout the thesis, along with simplifications and additional information added in response to the growing need for their use. All of the above ultimately aim to find and study, and conclude to the verification and presentation of an already existing method which combines the widely known and used out of these criteria. The classification methods presented are the Geotechnical Classification RMR, the Q System, the RMi Classification, and, last but not least, the Geological Strength Index GSI. The structure of the thesis consists of eight chapters, which include the following: The first chapter introduces the reader to the subject of this work. In this are stated the history and current use of the classification systems, their objectives, as well as the empirical criteria of rock mass strength. The second chapter is exclusively about the Geotechnical Order RMR and the updates it received over the years. The third chapter consists of the Q system. How to use it properly in the field, the support designing and its application for TBM drilling. In the fourth chapter, we present the advantages of RMi system, restrictions arising from its use and the way in which the scale of rock mass effects the rating. The fifth chapter is devoted to the GSI Index and its use. The cases when it shouldn’t be applied are stated, and how the presence of water affects the rating. Throughout the sixth chapter, we present the various correlations of the Rock Mass Rating Systems. The seventh chapter, which along with the sixth are the main body of the thesis, consists of the presentation and analysis of the results obtained from the correlation of criteria, with the help of chart of Rock Mass Textures. Finally, in the eighth and last chapter we present our conclusions and propose ways that this issue of the criteria correlation could be further studied.	en
