Abstract：According to the reinforcement issue of tunnels which are located in the deep landslide，a kind of self-anchored landside tunnel strengthening structure system is put forward. To the system，only the landslide，which is directly related to the tunnel stability，around the tunnel is taken anti-slide and reinforcement treatment with anti-slide pile and anchor cable，at the same time，strengthening tunnel lining structure. The tunnel lining structure，anti-slide pile and anchor cable form the self-anchored landslide tunnel strengthening structure system. The strengthening structure，which belongs to the statically indeterminate structure，will make slide bed as the stable support point of pile and anchor cable. According to the characteristics of the strengthening structure system，the physical and mechanical model is established，and the matrix transfer method is used to the theoretical derivation，internal forces and displacements of the reinforcement system are obtained.Example analysis results show that as a result of the action of anchor cable，the adverse stress of tunnel wall has been improved，and the anti-slide pile can constraint the deformation of tunnel invert and lining. Accordingly，the stress and deformation of the tunnel lining structure can be optimized and controlled by the anchor cable and anti-slide pile structure.
