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.]]>Alavi, M.,199621133Arshadnejad, Sh., H. Poshtvan and H.
