Combining with the tunneling of exit on certain multi-arch tunnel in shallow and soft stratum,the structure-load-elastic reaction model was employed to analyze the bearing capacity of the tunnel support system.A coupling analysis was conducted with respect to the relationship between the stiffness of surrounding rock and support system using FEM,the stress of shotcrete of various thickness and the relationship between steel frame parameters and its support effect was obtained.Based on the above work,the reasonable initial support parameter was proposed.In addition,the reasonable secondary lining was discussed in the paper as well.
