Pressure tunnels are used to transfer water under high pressure values. Considered deterministic terms and conditions contributed in design of such tunnels significantly affect results of any related analysis, resulting in necessity of a realistic modeling containing any possible situation. In this paper, modeling discussion, analysis and design process of a pressure tunnel is presented regarding practical conditions usually available. this procedure contains initial data which must be provided, discussion on functionality of common support systems in variable executional conditions, modeling details and tips, seepage analysis in potential cases, stress/strain nanlysis and design of liner besed on reinforced concrete design concepts.
