Tunnel energy dissipation, shock absorption and fracture resistance structure system

The invention provides a tunnel energy dissipation and shock absorption anti-fracture structure system, and relates to the technical field of tunnel structure shock insulation and shock absorption. The structure comprises inner pipe pieces and outer pipe pieces surrounding the outer portions of the inner pipe pieces, the multiple outer pipe pieces and the multiple inner pipe pieces are assembled to form a tunnel main body structure, the adjacent outer pipe pieces are flexibly spliced, gaps are reserved between the outer pipe pieces and the inner pipe pieces, and multiple energy dissipation supporting devices which are fixedly connected with the outer pipe pieces and the inner pipe pieces and arranged at intervals are arranged in the gaps; buffering blocks are arranged between the adjacent energy dissipation supporting devices, and when external soil bodies generate relative dislocation, the energy dissipation supporting devices can conduct radial and axial deformation energy dissipation in a self-adaptive mod
