Research on retaining the middle heading and spraying steel fiber concrete support method for large-span bifurcated tunnel
In order to solve the problem of surrounding rock deformation during the construction of large-span bifurcated tunnels, this article takes the Yangang East Interchange project as the engineering background, and combines with the existing construction design scheme of large-span bifurcated tunnels, establishes a construction method of retaining the middle heading and spraying steel fiber concrete. Firstly, the construction process of retaining the steel fiber reinforced concrete construction method for the middle guide pit was provided. Then, numerical models of B and C bifurcation tunnels were established based on universal finite element software. From the perspective of surrounding rock deformation, the advantages of this project’s construction method over the original design construction method were analyzed. Research has shown that the construction method proposed in this article not only significantly controls arch crown settlement and inverted arch uplift, but also improves construction efficiency. This study can provide reference for the construction of urban bifurcated tunnels.
