For shallow buried tunnels with poor surrounding rock stability, reasonable construction methods have great significance for ensuring tunnel construction safety and controlling construction quality. Taking Wushutou Tunnel as an example, three different construction methods of double-side guide pit method, CD method (single- side guide pit method), three-step plus temporary inverted arch method are comprehensively analyzed, and three engineering methods are used by FLAC software. Simulate and analyze the plastic zone change and surrounding rock deformation of different construction methods tunnels, and put forward the construction method in accor- dance with the project, and compare the monitoring data at the same time. The research results show that the double-wall method can ensure the stability of surrounding rock and the deformation of surrounding rock, and optimize the construction parameters and key steps of the double-wall method, which can provide a reference for the construction of such highway tunnels.
