Single tower cable-stayed bridge with unsymmetrical plane broken line arranged bridge deck and building method thereof

Abstract

The invention relates to a single tower cable-stayed bridge with an unsymmetrical plane broken line arranged bridge deck and a building method thereof, which belong to the cable-stayed bridge with the unsymmetrical plane broken line arranged bridge deck and the building method thereof. The single tower cable-stayed bridge with the unsymmetrical plane broken line arranged bridge deck comprises an unsymmetrical pyramid-type bridge tower and bridge piers, wherein the bridge piers are arranged at the two ends of the bridge; two ends of a long bridge deck and a short bridge deck are fixedly connected with the unsymmetrical pyramid-type bridge tower and the bridge piers, respectively; two ends of inhaul cables are respectively connected with tower columns of the unsymmetrical pyramid-type bridge tower and the bridge deck; the two sides of the long bridge deck or the short bridge deck are fixedly connected with arc damping cables, respectively. According to the invention, the single tower cable-stayed bridge with the unsymmetrical plane broken line arranged bridge deck can be used for hydraulic wading cable-stayed bridge structural designs; the technology of the single tower cable-stayed bridge is simple and convenient; the broken line angle of the single tower cable-stayed bridge can be set at 0-30 degrees according to needs; as the damping cables are arranged, the seismic capability of the cable-stayed bridge is improved, bridge deck slab displacement is also effectively limited, the stability of the bridge deck in use is improved, and an inhaul cable protecting method has a long-acting effect.

Description

Technical field [0001] The invention belongs to a cable-stayed bridge with asymmetrical plane broken line layout bridge deck and a construction method thereof. Background technique [0002] As we all know, cable-stayed bridges are long-span structures, and different arrangements can be used for different geological and topographical conditions. Generally, single-tower cable-stayed structures are mostly arranged in a symmetrical straight line, which can balance the load transferred by the bridge deck through the tower type. The mid-tower structure uses symmetrical bearing interaction to reduce the load, which can reduce the structural bearing system, reduce the amount of structural engineering, and effectively save investment; the side-tower structure needs to bear the load transferred from the bridge deck through the tower itself. Because the cable-stayed bridge does not block water, has a light structure and a beautiful space, the cable-stayed bridge structure has become an imp...

Problems solved by technology

Although the cable-stayed bridge has the above-mentioned many advantages, there are still the following problems: because the cable-stayed bridge is a multi-time statically indeterminate structure, the design calculation is relatively complicated, the cable-stayed cable is expensive to manufacture, and the installation and debugging require a high level of equipment, so it is difficult The durability and anti-corrosion requirements of large and cable-stayed cables are high, and the anti-corrosion of cable-stayed bridges is directly related to the safety and life of the cable-stayed bridge project. Measures need to be taken to improve its wind resistance stability and avoid resonance damage caused by wind
