| Abstract: | The polypropylene fiber reinforced concrete,which is a new type of the tunnel lining structure,has the characteristic of easy construction and can improve the concrete behavior and durability. To assure the safety in the construction process of the polypropylene fiber reinforced concrete lining structure, the nonlinear finite element method is used to analyze the large section tunnel excavation and the anchor sprayed lining process within the hard rock mass of the Dongjusi railway tunnel. The numerical analysis is carried out to investigate the force and the displacement distribution of the anchor sprayed concrete layer and the plastic distribution region around the tunnel during the large section tunnel excavation and anchor sprayed lining construction process. The rock mass stability and the lining effect after the construction of the lining structure is studied. |
