These instructions give you basic guidelines for preparing papers for conference proceedings. The paper first introduces the principle and key of tunnel-supporting characteristic curve, and analyzes the stress distribution behavior and deformation of surrounding rock after excavation according to the Moll-Coulomb strength destruction criterion. And then, on the base of discussing the rigidity of preliminary supporting structure, the author explains the solution method of composite supporting supply curve. What's more, combining with the supporting structure optimization design of Jiepaiguang Tunnel on Shiman Expressway, the thesis represents the practical application of convergence-confinement method, and discusses the parameter arrangement, the strata convergence curve, the preliminary supporting stress & deformation, and together with the interaction between supporting structure and surrounding rock. Finally, the optimal design scheme got in the paper provides theoretical foundation for the construction.
