Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The embodiment of the present invention provides a technical solution: a model building system for a concrete continuous box girder bridge. When the span of a continuous system girder bridge exceeds 40 to 60 m or more, the main girder mostly adopts a box-shaped section, and its structure and layout are flexible. , suitable for various construction methods such as cast-in-place construction with supports, hole-by-hole construction, cantilever construction, etc.;

[0025] The bridges constructed by the present invention using the jacking method...

Abstract

The invention discloses a model building system of a concrete continuous box girder bridge. The model building system comprises the specific steps that 1, comparison and selection are conducted on a bridge type building scheme, and a bridge construction scheme is drafted; step 2, drawing up the size of the upper structure of the bridge; 3, establishing a space finite element model of the bridge structure by applying midas civil software; 4, performing curve continuous box girder counter-force checking calculation, and continuously adjusting the structure size or reinforcing bars until all checking calculations meet the standard; 5, structural internal force calculation and internal force combination are carried out; the invention relates to the technical field of bridge construction. According to the model building system of the concrete continuous box girder bridge, the problems that an existing data simulation system is too tedious in process, large in error and incomplete in analysis factor are solved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a model building system for a concrete continuous box girder bridge. Background technique [0002] The advantages of concrete continuous box girder are low cost, good durability, low maintenance, comfortable driving, beautiful appearance, and land saving. Therefore, it has been more and more widely used. In the 1970s, continuous box girder bridges began to be built on highways in my country. So far, many continuous box girder bridges have been built. With the rapid growth of traffic volume and the increase of vehicle speed, people hope to have fast and comfortable traffic conditions when traveling. [0003] With the rapid growth of traffic volume and the increase of vehicle speed, people hope to have fast and comfortable traffic conditions when traveling. Continuous box girder has been widely used. It has less bridge deck joints, small beam height, high rigidity and st...
