Novel two-way curved arch bridge

Abstract

The invention relates to a novel two-way curved arch bridge. The novel two-way curved arch bridge comprises a main beam, main arch ribs, auxiliary arch ribs, a side hanging rods and middle hanging rods, wherein one parabolic main arch rib is arranged on each of the two sides of the main beam; a plurality of parabolic auxiliary arch ribs are arranged between the two main arch ribs; the two ends (namely arch feet) of the main arch ribs are positioned above middle piers respectively; the two ends of the auxiliary arch ribs are fixed to the two main arch ribs respectively. Compared with the priorart, the novel two-way curved arch bridge provided by the invention has the advantages as follows: due to the actions of the hanging rods and the auxiliary arch ribs which are added between the parabolic main arch ribs, stress on a cross beam is reduced for a wide bridge, so that reduction on the beam height of the cross beam and control of the height of a wide bridge structure are facilitated.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a novel double-curved arch bridge. Background technique [0002] When encountering a bridge design with a wide deck, the tied arch bridge is usually designed as a tied arch bridge with three bearing surfaces or two tied arch bridges arranged side by side. The size of the rib structure leaves 4-7m for the width of the bridge deck, which increases the width of the bridge deck or the width of the red line of the route, and the driving space on the bridge deck creates a strong sense of depression, which is visually opaque; and it is neither economical nor beautiful. Contents of the invention [0003] The object of the present invention is to provide a novel double-curved arch bridge with more optimized stress and better economy in order to overcome the defects of the above-mentioned prior art. [0004] The purpose of the present invention can be achieved through the following tech...
