Tunnel Support Structure System and Its Synergy

Abstract

The tunnel support system is composed of lining bolt and steel frame. It is of great significance to effectively control the deformation of the surrounding rock of the tunnel make full use of the characteristics of different support methods and formulate an economical and effective support plan to ensure the safe operation of the tunnel structure. This paper clarifies the synergistic relationship between the support structure and the surrounding rock based on their fundamental characteristics and functions. Various support structures and components are also discussed in this paper. Additionally the paper presents an optimized design of the tunnel support structure system.
