Controlling the critical construction steps of the CRD method plays an important role in ensuring construction and ensuring construction safety. When using the CRD method for the construction of the Re Shuitang No. 3 tunnel, through the numerical simulation of the initial support structure and the temporary support structure during the tunnel construction process, it is concluded that the left upper step, the upper right step and the temporary support structure are obviously stressed. Construction steps. According to the analysis results, the surrounding rock of the vault should be strengthened in advance, and the second lining structure should be applied after the surrounding rock is stabilized.
