A long-span corridor comprising two sets of floor cantilevered inclined trusses combined with suspension cable bearing, comprising floor cantilevered inclined trusses, floor double-arch trusses, radial circumferential connecting structures, V-shaped support structures, corridor truss structures and suspension cable bearing structures, wherein the two sets of floor cantilevered inclined trusses symmetrically form a combination of the floor cantilevered inclined trusses, each set of floor cantilevered inclined trusses comprise two trapezoidal tapering planar inclined trusses that are obliquely joined, and the two trapezoidal tapering planar inclined trusses of each set of floor cantilevered inclined trusses are connected to each other through a combination of the floor double-arch trusses and through the radial circumferential connecting structures to form a single-set system;
- wherein the floor double-arch trusses comprise two-end floor vertical arc-shaped arch trusses, two trusses of two-end floor vertical arc-shaped arch trusses are arranged at a lower part of the single-set system at intervals, end parts of the two-end floor vertical arc-shaped arch trusses are inclined truss bottom floor ends (5), and two sets of the floor double-arch trusses symmetrically form a combination of the floor double-arch trusses;
- wherein the radial circumferential connecting structures comprise radial circumferential orthogonal small trusses and radial circumferential connecting steel beams, and the radial circumferential orthogonal small trusses comprise middle shaft radial inclined long trusses (11), two-side radial inclined short trusses (12) and circumferential arc-shaped arch trusses (13);
- wherein each single-set system is also connected to the V-shaped support structures;
- the V-shaped support structures comprise V-shaped support inclined columns (16) and V-shaped support top beams (17);
- and top ends of the two V-shaped support inclined columns (16) are respectively connected to two ends of the V-shaped support top beams (17) while bottom ends are mutually joined, connected to and fixedly supported on the ground;
- and
- wherein the corridor truss structures are arranged between two single-set systems;
- the suspension cable bearing structures comprise suspension cables (32), spars (33) and slings (34), two ends of the suspension cables (32) are connected to the two single-set systems, the suspension cables (32) are connected to the slings (34), and each of the slings (34) comprises a cable member section (35), a cable measuring section (36), a cable regulating section (37) and a cable anchoring end;
- and the suspension cables (32) are laterally supported by the spars (33).
