Abstract：
Aimed at the construction difficulties of the Xihekou shallow-buried large-section tunnel that passes under the Great Wall of the Ming dynasty, this paper proposes a comprehensive safety control technology, i.e., pre-reinforcement by cement-water-glass grouting on the ground and a double-layer pipe-roof support in the tunnel; construction by double-side drift with a short bench; and locally optimizing the support parameters. Based on a model test, the feasibility of the scheme was verified and control standards of ground settlement were determined. Scheme rationality was assessed in light of field monitoring.
