چکیده مقاله:
in this research, considering the experiment of tunnel inflow due to 10 different tun nels in iran and adopting idea from idea from site geomechaics rating like RMR, a new method has been devolped for rating the tunel site to evaluate the potential of tunnel inflow according to the preliminary investigation data. this method is called site groundwater rating SGR considered parameters in this mehod are:jont frequency , joint aperture, karstification, crashed zone, schisty , head of water above tunnel , soil permeability, and annual raning using these parameters and following SGR method tunnel site can be categorized into six rates as follow no risk moderate risk risky, high risk and critical . the method has been checked out with the observed groundwater in flow of ghomroud and also implied to rate the amirkabir tunnel site in iran.
