Problems solved by technology

[0005] However, the topography and landform drawings provided in related technologies are generally two-dimensional drawings, and the length and proportion of various lines in the drawings are manually set, which is prone to data errors, and it is difficult to find topography and topography in the plane display of two-dimensional drawings. Data errors make it difficult to provide accurate data support for bridge erection and bring inconvenience to bridge construction

Abstract

The invention relates to the technical field of landform modeling and particularly relates to a method and a device for achieving three-dimensional landform modeling by using BIM. The method for achieving the three-dimensional landform modeling by using the BIM comprises the following steps: obtaining survey data of a construction site; determining types of the survey data, wherein the types of the survey data comprise two-dimensional drawing data of the construction site and geological drilling information data of the construction site; and establishing a CATIA geological scale model for the survey data according to the determined types of the survey data. According to the method and the device for achieving the three-dimensional landform modeling by using the BIM, a three-dimensional landform model of a bridge establishing position is established and a landform of the bridge establishing position is directly displayed, so that the accuracy of producing the data for bridge erection is improved.

Description

technical field [0001] The present invention relates to the technical field of topography and topography modeling, in particular to a method and device for realizing three-dimensional topography and topography modeling by using a building information model (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] In the process of design, erection and selection of construction methods of steel truss arch bridges, not only factors such as bridge form, span, width, traffic, equipment, construction period and cost must be considered, but also the hydrology, geology, topography and other topography where the bridge is located. condition. [0004] In related technologies, the main method of providing the topography of the bridge constru...
