Large-span corridor structure composed of arc-shaped cantilever trusses and stay cable supporting structures and constituting method thereof

A large-span corridor structure composed of arc-shaped cantilever trusses and stay cable supporting structures, comprising cantilever trusses with arc-shaped facades, orthogonal connecting trusses at a corridor, connecting trusses at cantilever portions, corridor truss structures, and stay cable supporting structures;

• wherein
• the cantilever trusses with arc-shaped facades are composed of two sets of ultra-long cantilever trusses with arc-shaped facades and triquetrous planes wherein the two sets of ultra-long cantilever trusses with arc-shaped facades and triquetrous planes are fixedly supported by ground and symmetrical, and each are formed of several ultra-long cantilever trusses with arc-shaped facades and triquetrous planes arranged in parallel at a certain distance;
• the orthogonal connecting trusses at the corridor are located between the several ultra-long cantilever trusses with arc-shaped facades and triquetrous planes of each cantilever truss with arc-shaped facades at a height of the corridor of each set of ultra-long cantilever trusses with arc-shaped facades, and is in the form of a planar truss and is orthogonally arranged with and rigidly connected to the cantilever trusses with arc-shaped facades;
• the connecting trusses at cantilever portions are located between the several ultra-long cantilever trusses with arc-shaped facades and triquetrous planes and are in the form of a planar truss, and are arranged at a certain distance and orthogonally rigidly connected to the ultra-long cantilever trusses with arc-shaped facades and triquetrous planes;
• the corridor truss structures are composed of a middle large-span corridor truss area and cantilever corridor truss areas on both sides, and are in the form of a double-layer-union jack-shaped diagonal bracing truss structure, whose cantilever ends are rigidly supported on the cantilever trusses with arc-shaped facades, and form a horizontal integral continuity truss structure;
• and
• the stay cable supporting structures are located between the cantilever portions of the cantilever trusses with arc-shaped facades and the corridor truss structures, and includes stay cable supporting structures in the cantilever corridor truss areas and stay cable supporting structures in the large-span corridor truss area, top ends of stay cables of the stay cable supporting structures are suspended at a connection of the connecting trusses at cantilever portions and the cantilever trusses with arc-shaped facades or at top cantilever ends of the cantilever trusses with arc-shaped facades, bottom ends of the stay cables of the stay cable supporting structures are connected at cantilever portions and large-span portion of the corridor truss structures.
