Problems solved by technology

In the field of highway tunnel engineering, there is a lack of tools for parametric batch creation of BIM models, and the modeling efficiency is not high. The system cannot match the composite lining structure for tunnel segments according to the surrounding rock grade; the system cannot locate the coordinates of the communication channel according to the pile number of the communication channel. And place the 3D model of the communication channel and automatically remove the overlapping parts

Embodiment 1

[0032] Depend on figure 1 As shown, the present invention is a method for dynamically creating a BIM model of a highway tunnel project based on a Unity platform. This method mainly goes through the following steps in the process of realizing the creation of the tunnel model:

[0033] S1. Import the route information and key stake number information of the tunnel based on the route file, analyze the route file, read the design line list under the route file, and obtain the design line Guid where the current tunnel is located. The design line Guid is obtained from the route database file The primary key of each design line is the unique identifier of the design line generated through a series of coding methods. According to the key stake number information, the engineering coordinates are analyzed, and the engineering coordinates are shifted to the origin and converted into the available coordinates of the tunnel in the three-dimensional space. The three-dimensional space fits ...

Abstract

The invention discloses a highway tunnel engineering BIM model dynamic creation method based on a Unity platform, and the method comprises the steps: importing route design line horizontal and vertical information and key stake number information of tunnel engineering based on a route file; then reading geological prospecting data, importing surrounding rock grades and description, building a lining model, and segmenting the tunnel; then, creating a supporting component scheme based on the composite lining general design drawing; designing a tunnel body; designing a lining, a tunnel portal anda connection channel; according to the method, the highway tunnel engineering design scheme can be displayed more clearly and visually in a three-dimensional visualization mode, dynamic interaction between input design parameters and tunnel engineering model creation is achieved, the design concept of designers is reflected in real time, and the tunnel engineering BIM modeling efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of dynamic parameterized creation of highway tunnel engineering information models, in particular to a method for dynamically creating BIM models of highway tunnel engineering based on a Unity platform. Background technique [0002] At present, there are mainly three platforms that carry BIM technology at home and abroad, namely Autodesk, Bentley and Dassault platforms. The idea of ​​creating models on these three platforms is mainly manual creation, and assists in improving the efficiency of model creation with basic component models. In the field of highway tunnel engineering, there is a lack of tools for parametric batch creation of BIM models, and the modeling efficiency is not high. The system cannot match the composite lining structure for tunnel segments according to the surrounding rock grade; the system cannot locate the coordinates of the communication channel according to the pile number of the communication...
