    Abstract
  • For shallow-buried oversized cross-section flat structure tunnels, reasonable cross-section design and construction method selection are crucial for ensuring tunnel construction safety. In this study, finite difference computation software FLAC 3D was employed to optimize the flat ratio and construction method for Tunnel No.2 of Tonggang Road in the Shenzhen-Shanwei Cooperation Zone. The effects of four different flat ratios and two distinct construction methods on the deformation and stress distribution of the surrounding rock were analyzed, and the entropy weight method was utilized to determine the weights of indicators such as plastic zone area, vault settlement, and ground settlement. Each scheme was evaluated through comprehensive scoring and comparison, leading to the proposal of the optimal flat ratio and construction method for the studied tunnel project. Numerical simulation results indicated that a section design with a flat ratio of 0.65 combined with the double-side drift excavation method represents the optimal solution. The high consistency between field construction monitoring data and numerical simulation results was demonstrated, validating the accuracy of the established numerical model and the feasibility of the proposed optimized construction scheme. The findings provide theoretical support and data references for the construction of shallow buried super-large sections of flat structure tunnels.
