Problems solved by technology

[0003] However, for arch bridges, if the two middle spans are the main span, and the main span and side spans are large, the arch feet are prone to uneven stress, which is not only unfavorable to the bridge piers, but also deteriorates the stability of the overall bridge structure

Embodiment Construction

[0032] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0033] It should be noted that when an element is “fixed” to another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terminology used herein in the descrip...

Abstract

The invention discloses an arch bridge system, which includes a bridge deck structure; the pier structure includes a first pier, a second pier and a third pier; the arch rib structure includes a first arch rib and a second arch rib, and one end of the first arch rib is On the first pier and below the bridge deck structure, one end of the second arch rib is set on the third pier and below the bridge deck structure, and the other end of the first arch rib and the other end of the second arch rib are both set on the second arch rib The second bridge pier corresponds to the position of the bridge deck structure; the diagonal brace structure includes the first diagonal brace and the second diagonal brace, the two ends of the first diagonal brace are respectively supported on the first bridge pier and the bridge deck structure, the two ends of the second diagonal The ends are respectively supported on the third pier and the bridge deck structure. The first arch rib and the second arch rib form an under-supported arch bridge structure at the position of the second pier, the first arch rib forms a mid-support arch bridge structure at the corresponding position of the first pier, and the second arch rib forms an in-progress arch bridge structure at the corresponding position of the third pier The continuous arch bridge structure solves the problem of uneven stress on the arch foot structure of the simple intermediate arch bridge.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an arch bridge system. Background technique [0002] An arch bridge refers to a bridge with an arch as the main load-bearing member of the structure in the vertical plane. According to the relative positional relationship between the bridge deck and the arch ribs, arch bridges can be divided into three different types of arch bridge structures: top-supporting, middle-supporting and bottom-supporting. [0003] However, for arch bridges, if the two middle spans are the main span, and the main span and side spans are large, the arch feet are prone to uneven stress, which is not only unfavorable to the bridge piers, but also deteriorates the stability of the overall bridge structure . Contents of the invention [0004] Based on this, it is necessary to provide an arch bridge system; the force of the arch foot of the arch bridge system is relatively uniform, and the st...
