  • Method for deformation control of large-span tunnel in chlorite schist stratum
    Patent number: 10280749
    Abstract: A method for deformation control of large-span tunnel in chlorite schist stratum. The method divides the large deformation of large-span tunnel in chlorite schist stratum into five deformation grades according to the surrounding rock conditions of the tunnel. In response to each deformation grade, the deformation control of large-span tunnel is determined so as to ensure the safety and stability of the tunnel support structure and to avoid the clearance intrusion caused by tunnel deformation.
    Type: Grant
