Summary: | The invention relates to a tunnel lining structure with an eternally un-dismountable lining tire and a construction installation method of the tunnel lining structure. The tunnel lining structure is mainly composed of the lining tire and a steel arch. According to the tunnel lining structure and the construction installation method of the tunnel lining structure of the invention, the installation position of the lining tire and the shape of the lining tire are determined through numerical simulation; stress generated by the deformation of surrounding rock can be uniformly transferred to the steel arch through the air and the flexibility of rubber; and therefore, the area of the fracture surface of the section steel and requirements for strength can be greatly decreased, and the utilization rate of the steel arch can be fully utilized, and the local failure of the steel arch can be avoided to the greatest extent, and construction cost can be saved to an extremely great extent, and the surrounding rock fully utilizes the supporting and protecting ability of the surrounding rock itself assuredly, and local failure of the surrounding rock can be prevented, and safety can be improved. |
