Traffic support tunnels are among the most widely used structures in tunnel engineering,characterized by short service life,small tunnel section,and poor durability.For traffic tunnels,traditional composite lining structures have problems such as high safety hazards and inefficiencies.In addition,the confined space,steep gradients,and complex environments of traffic support tunnels make secondary lining construction challenging and compromise safety and quality.Therefore,it is of great significance to conduct research on the collaborative bearing mechanism of support structures for traffic tunnels and propose suitable support structure types for traffic tunnels.This project takes the construction support tunnel of Wangwuyan Tunnel on G4216 highway as the research object.Through a combination of research analysis,numerical simulation,and on-site measurement,the collaborative force mechanism and optimization of the support structure are studied.
