Abstract:
The Siah Bishe pumped storage project is now under construction. The investigation results, the stability analysis for the power intake shafts and head race tunnels at vicinity of a rock slope are discussed in this study. Power intake shafts and head race tunnels in Siah Bishe dam have a complex geometry. In site investigation was found 3 joint sets in the rock mass. Therefore first of all the structure analyzed for finding underground wedges by Unwedge software. After that overall and local stability of the power intake shafts, the headrace tunnels and slope were analyzed by two conditions (static and pseudo static). Complex geometry of the project due to stability analysis was used 3D modeling by ABAQUS software. Results show that when a rock slope is closed to a shaft, 2D modeling is wrong. Especially, there were some other underground spaces, like tunnels. Results of numerical 3D modeling show that maximum displacement occurs in the roof of the tunnels between transition zone-conjunction of shaft to tunnel- and tunnel portal.
