Application of a New Multi-functional Frame Shed Tunnel

In order to optimize the structural design of mountain side road in mountainous towns and solve the problem of support design of excavated subgrade slope affected by mountain terrain, an anti-slide shed tunnel scheme with double row anti-slide piles and building frame structure is proposed. According to the application of specific engineering projects, the stress characteristics of the shed tunnel was analyzed, and the techniques of the shed tunnel structure and the traditional subgrade retaining structure were compared. The structural calculation and construction process simulation were discussed. The research shows that the shed tunnel structure has strong lateral stiffness, and each beam and column structure could bear force as a whole. The construction safety could be achieved because of top-down method, and new scheme for the development and utilization of urban public space are provided.
