Abstract
To clarify the stability of tunnel face and tunnel convergence excavated in squeezing rock, the numrical analysis was conducted. And the Nanao Tunnel was analyzed, which constructed tunnel in squeezing rock. As a result, tunnel face stability can be improve by using face bolts. And tunnel cross deformation can restrict by tunnel ring closure immediately. AIso, from analysis result of the Nanao tunnel, it is possibletocontrole the cross deformation and stabilize tunnel cross when closure stage is properly to rock state. And also, measurement result and numerical analysis are analogously.
