Abstract
The Behesht-abad Water Conveyance Tunnel is one of the most important tunnels conveying water to central Iran plain having 60 km length and 6 m diameter. The tunnel portal intersects with important faults of the region which is nearby Ardal city. Therefore, the rock mass surrounding the tunnel portal faces instability problem. Initially, the joints characteristics of the rock mass surrounding the inlet portal were evaluated to find the dominant joint sets along with the characteristics required for stability analyses inputs. Also the deformation modulus and other engineering properties of the rock mass were assessed using the available drilled boreholes data. The extensive stability analyses were conducted using stereographic, empirical SMR, limit state equilibrium and 3-dimensional discontinuum numerical methods. Finally, the results of the analyses were compared together.
