| Abstract: | Tujiangchong Tunnel of Chang-Ji Expressway was as engineering background in this paper. The tunnel construction of multi-arch tunnel with composite curve middle-wall was simulated by FLAC3D. The deformation characteristics of primary lining, axial forces of rock bolts, the stress of primary lining and secondary lining structure were obtained. The mechanical characteristics of lining structure in multi-arch tunnel with composite curve middle-wall were analyzed and the safety of secondary lining structure was evaluated in this tunnel. |
