Tunnel structure shield section parameterization design method based on BIM

Abstract

The invention discloses a BIM (Building Information Modeling)-based tunnel structure shield section parameterization design method which comprises the following steps: S1, carrying out two-dimensional design on a plane route and a longitudinal section route of a tunnel shield section, analyzing and outputting route data of the shield section, and carrying out plane route and longitudinal section design on the tunnel shield section in a two-dimensional design platform; s2, establishing a three-dimensional component model of a shield segment standard block, an adjacent block and a top sealing block, and placing a base point of the shield segment on the round point; the method has the advantages that rapid parameterized design work is achieved by developing existing two-dimensional and three-dimensional design platforms, the problems that most of tunnel shield modeling is manual modeling, the efficiency is low, most of tunnels are space curves, and the accuracy of manual modeling is low are solved, and through combination of two-dimensional design and three-dimensional design, the construction efficiency is greatly improved. The method comprises the following steps of: modeling a tunnel shield route, a shield segment and a shield internal structure, and designing, drawing and quantity.

Description

technical field [0001] The invention relates to the technical field of BIM in the engineering design industry, in particular to a parametric design method for shield sections of tunnel structures based on BIM. Background technique [0002] BIM is a building information modeling technology, which is a data tool applied to engineering design, construction and management. [0003] Parametric technology is a revolutionary technology produced in the continuous development of Computer Aided Design (CAD) technology. When the manufacturing industry puts forward higher requirements for automation and intelligence, it needs more suitable technical support. As a result, parameterization technology came into being. Compared with traditional CAD design, parametric design is not designed for a certain geometric shape, but a class of geometric shapes with common feature parameters. By modifying the feature parameters, similar but different geometric shapes can be obtained. Use parameters...
