| Abstract | ||
| The Ahwaz urban railway tunnel, which is at the stage of construction, is located within the area of Ahwaz anticline and the associated reverse fault. The geological hazards during drilling line 1 tunnel may include variable adhesion between the rotating cutting head shield of the TBM, variable inhomogeneity at the rotating head, planer and wedge failure on the tunnel's roof and sides in addition to the geometric effects of the different joint sets. These effects are studied using Unwedge 3.0 and Dips software. The occurrence of earthquakes on Ahwaz fault would create liquefaction hazard in the saturated sand soils of the fault footwall at the central and southwestern parts of the urban railway. | ||
