<p>The current investigation concentrates on enhancing structural stability in tunnel construction for the Xi’an metro system, highlighting design processes associated with tunnel linings and support methods in urban geotechnical engineering. In rapidly expanding cities where urban metro networks are becoming more intricate, guaranteeing the safety, stability, and efficiency of underground infrastructure is becoming more critical. This study comprehensively examines the Xi’an metro tunnel case, emphasizing the different lining materials, support frameworks, and design approaches utilized while considering the geological conditions, elevated urban density, and variable environmental factors. The study examines the effectiveness of different lining designs regarding bearing capacity, durability, and ease of construction, considering significant concerns regarding soil-structure interaction, groundwater management, and risk reduction. In the design, a method based on overall circular lining calculations is employed to determine the lining structure, and modeling and analysis are conducted using Lizheng deep foundation software to compute the relevant internal forces of the structure. The diagrams for axial force, shear force, and bending moment have been created in the results. This enhancement to the structural strength and eco-friendliness of metro tunnel systems aids in reducing interruptions to normal operations, extends the operational lifespan of a tunnel, and guides the development of future urban infrastructure.</p>
