Problems solved by technology

However, the double helix arch has an enveloping effect on the bridge deck, which affects the driving vision
In addition, the construction of the two intersecting double helix space arches and the space cable network system arranged on the arches is also difficult, which is not conducive to the practical application of this type of bridge

Abstract

The invention discloses a bridge structure system combined with a single spiral arch and suspension cables, which includes a bridge deck system, a spiral arch, suspension cables and suspension cables; The bottom of the spiral arch below is supported on the pile cap; there is a support at the bottom of the side of the bridge deck system, and the support is supported on the support on the inner side of the spiral arch; the upper end of the sling is fixed on the The top of the spiral arch above the system, and the lower end is fixed at the longitudinal axis of the bridge deck system; the suspension cables arranged on both sides of the bridge system are correspondingly anchored on the spiral arch and the end of the bridge system. The invention has beautiful appearance, good driving vision, convenient construction and safe and stable overall structure.

Description

technical field [0001] The invention belongs to the technical field of bridge structures, and in particular relates to a bridge structure system combined with a single spiral arch and suspension cables. Background technique [0002] Spiral arch bridge is a novel space arch bridge. The foreign spiral arch bridge has Singapore Double Helix Bridge. This bridge is a pedestrian bridge with a total length of 280m. Two spiral curves are intertwined to form the main stress system of the bridge span structure. [0003] The domestic spiral arch bridge is Sanshan Bridge in Beijing. The bridge has two-way 4 lanes, sidewalks on both sides, and a total length of 452m. The Sanshan Bridge also adopts a double spiral arch structure. The bridge structure is suspended by high-strength steel cables, and the corrugated surface formed by the steel cables encloses the interior space of the bridge. [0004] The double-helix arch structure of the spiral arch bridge is not only novel and beautiful i...
