Objective: To explore the influence of different supporting structures on the long-term stability of tunnel surrounding rock. Methods: establish the mechanical model of tunnel surrounding rock, and explore its influence on the model shape by changing the support structure parameters. Results: different supporting structures will affect the shape of tunnel surrounding rock model, indicating that it has a certain impact on the long-term stability of tunnel surrounding rock. Conclusion: when carrying out tunnel surrounding rock support, four reasonable support parameter design schemes, such as 0.5m structural plane spacing and 75 ° ~90 ° inclination angle, can be selected to ensure the safety and stability of tunnel surrounding rock to the greatest extent.
