Q-Sistem

Q-Sistem (NGI indeks), koji su uveli Nick Barton i saradnici na Norveškom geotehničkom institutu 1974. godine, predstavlja alternativnu klasifikaciju stenske mase RMR-u. Kombinuje šest parametara u bezdimenzioni indeks Q koji se kreće od 0,001 do 1000, gde više vrednosti Q ukazuju na bolji kvalitet stene. Q-Sistem je posebno cenjen za projektovanje tunela i podzemnih iskopavanja zbog eksplicitnog razmatranja hrapavosti pukotina i uticaja podzemnih voda.
