Method and device for realizing rapid steel truss arch bridge modeling by utilizing BIM

Abstract

The invention relates to the field of bridge construction and in particular relates to a method and a device for realizing rapid steel truss arch bridge modeling by utilizing BIM. The method comprises the following steps: constructing a framework model of a steel truss arch bridge according to two-dimensional drawing of the steel truss arch bridge; setting basic parts of the steel truss arch bridge in a layered mode by adopting a pre-constructed BIM knowledge base and tree structures, wherein the basic parts comprise parts used by a main arch ring of the steel truss arch bridge, parts used for an upright post on the arch of the steel truss arch bridge, and parts used by juncture piers, approach bridges and arch seats of the steel truss arch bridge; and constructing association between the parts by virtue of functional parameters of the various parts, thereby obtaining a BIM model. According to the method and the device for realizing rapid steel truss arch bridge modeling by utilizing BIM disclosed by the invention, the accuracy of data provided for bridge construction can be improved.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a method and device for realizing rapid modeling of a steel truss arch bridge by using BIM. Background technique [0002] With the continuous development of bridge construction technology, long-span bridges are emerging rapidly with each passing day, and steel truss arch bridges are widely used because of their better cross-domain capabilities than prestressed concrete bridges. [0003] There are many erection methods for steel truss arch bridges. The choice of construction method should not only consider the bridge form, span, width, hydrology, geology, terrain and other conditions of the bridge position, but also consider factors such as traffic, equipment, construction period and cost. . [0004] In the related art, the general method of erecting a steel truss arch bridge is: design the bridge drawing according to the topography of the bridge to be built and the functional ...

AI Technical Summary

Problems solved by technology

[0005] In related technologies, the bridge drawings designed by designers are generally two-dimensional drawings. The lengths and proportions of various lines in the drawings are manually set, which is prone to data errors, and it is difficult to find in the plane display of two-dimensional drawings. It is difficult to provide accurate data support for bridge construction and bring inconvenience to bridge construction
