Abstract
(Paper pages 2559-2574)
This paper presents a case study of the instability mechanism, to verify and
reinforcement method adopted construct collapsed zone of Sabzkuh water
conveyance tunnel in southwest Iran. The instability problems were
encountered during tunnel excavation due to the failure, changes in stress
field lead to deformation causing dilation and increasing the permeability of
sand and gravel layers, local fault gouge zones, landslide and in turn
significant reduction in shear strength and collapse in tunnel. IPE Arch
Support Technique (IAST) was, used for T1 part of Sabzkuh tunnel zone in
order to reinforce the ground around tunnel and to cross the zone falling. In
this study, Finite Element Method was employed for the quantitative
reinforcement effect with deformation modulus of ground, IPE length and
size. As a result, the settlement increases as length increases and decreases
with the increase of the deformation modulus of ground and IPE size.
