Abstract：
Using domestic and foreign experiences in non-ballasted track construction and related technical documents as references and the double-block non-ballasted track construction of tunnel groups on the Gui-Guang railway as a background, the equipment configuration and organization of logistics for non-ballasted track construction for tunnel groups in mountain areas were studied and the related procedures for construction in a double-track tunnel are proposed in this paper. Engineering practices indicate that in-situ assembly of the track panel using a combined track framework could be adapted to adjust to the curve radius of the track and guarantee the technical indexes of non-ballasted track construction, therefore having rapid construction conversion capability. With high precision and stiffness, the assembled track framework is recyclable to shorten the construction period and save construction costs.
