In combination with the real geological engineering conditions and the design parameters of the tunnel layout
numerical analysis is performed to analyze the rock mass stability for two different supporting structures
the ordinary concrete lining with thickness of 500 mm and the wet-sprayed polypropylene fiber reinforced concrete lining with the thickness of 200 mm respectively. The tunnel rock mass stability is analyzed for the stress
displacement and plastic zone distribution. The numerical simulation shows that the lining structure using the polypropylene fiber reinforced concrete is stable.
