Abstract In light of the clearance intrusion of the primary support in the Sujiawan tunnel, this paper determines relevant parameters for controlling support deformation based on checking the support structure and secondary lining with MIDAS-GTS software and analyzing the geological conditions of the tunnel body. Reasonable countermeasures are proposed after the analysis of required construction technologies, including strengthening geological surveys of the top of the tunnel's central line, improving the drainage system, enhancing the support system with an increased reserved deformation allowance, and intensifying tunnel monitoring and measurements.
