[0002] In the field of tunnel construction, the traditional method of technical briefing mainly relies on 2D design drawings and construction drawings. This method of briefing requires high spatial imagination and technical level of construction personnel, and it is easy to cause the loss of technical details during the briefing process. Since construction drawings are mostly 2D drawings, technicians need to rely on spatial imagination to construct the three-dimensional entity of the structure. For tunnels, which are complex entities composed of many structures, there is a problem that component conflicts are difficult to detect. In addition, the engineering quantity statistics of tunnel projects usually require manual calculations, which is not only inefficient, but also difficult to ensure accuracy. In the end, the construction information stored in the project is mainly retained in the form of construction drawings, and detailed component construction information is difficult to effectively retain.

[0003] The existing technology has the following deficiencies in the management of mining tunnel construction: 1. Technical briefings rely on 2D drawings and lack 3D visualization support, which makes it difficult for construction workers to accurately understand the construction details.

[0004] 2. Component conflict detection mainly relies on manual work, which is inefficient and prone to errors.

Steps S101 to S105 of modeling using the Revit series software not only improve the accuracy and efficiency of tunnel design and construction, but also provide strong support for construction safety, schedule control and later maintenance.Optionally, a 3D tunnel model is created based on the tunnel 2D construction drawing information. When establishing the BIM model, the modeling software is first selected. Commonly used software are corresponding software provided by Autodesk, Bentley, Dassault, and Nemetschek. Here, Autodesk's Revit series software is preferably used for modeling.

[0027] Optionally, when using Autodesk's Revit software to model the tunnel, the specific modeling steps are: S101: Determine the location of the tunnel and the 3D model of the topography and geology Import drawing information: First, you need to import the plan view, longitudinal section view and engineering geological map into Revit. This can be achieved through the "Import CAD" function under the "Insert" tab. During the import process, you can set the scale, rotation angle, etc. to ensure the accuracy and consistency of the drawings.

[0028] Create a 3D terrain model: Using imported engineering geological maps, use Revit's modeling tools to build a 3D model of the terrain. You can import geological data (such as digital elevation model DEM data) into Revit and use drawing tools to draw stratum boundaries and fill colors. In addition, you can also use Revit's wall elements to represent stratum boundaries.

[0029] Integrate terrain and tunnel location: Combine imported plan and profile views with the 3D terrain model to determine the exact location and direction of the tunnel. Ensure the tunnel accurately matches the terrain by adjusting the 3D view of the model.

[0030] S102: Constructing tunnel structure model Import cross-section drawings: Import the cross-section drawings of the tunnel into Revit using the same method as importing other drawings.

[0031] Create tunnel profile: Based on the cross-section drawing, use Revit's parametric modeling capabilities to create the tunnel profile. You can use Revit's family editor to define the tunnel's cross-sectional shape and size.

[0032] Generate tunnel structure model: Use visual programming tools such as Dynamo to perform parametric programming design of tunnel structure in combination with the centerline and section profile of the tunnel. Through Dynamo, the centerline of the road can be segmented and the corresponding section profile can be placed at the segmented position. Finally, a complete tunnel structure model is generated in Revit, either by placing a predefined family or directly creating a solid shape and then converting it into a Revit model.

[0033] Through the 3D modeling function of Revit, the structure and topographic geological conditions of the tunnel can be accurately simulated, the design errors can be reduced, and the accuracy and reliability of the design can be improved. At the same time, the use of parametric modeling and automation tools (such as Dynamo) can speed up the modeling process and improve the design efficiency. The established 3D model can be used as a common language between departments, so that different departments such as engineering, geology, and construction can understand and communicate engineering information more accurately. Through the BIM platform, data sharing and collaborative work can be achieved, and the collaborative efficiency of the engineering team can be improved. The detailed 3D model can provide intuitive guidance for construction, help construction personnel better understand the tunnel structure and construction requirements, and reduce errors and rework in construction. In addition, construction simulation and optimization can be carried out in the model to discover potential problems in advance and formulate more reasonable construction plans and management plans. The established tunnel model can be used for various analyses and evaluations, such as structural stability analysis, geological disaster risk assessment, etc. Through these analyses, a scientific basis can be provided for engineering decision-making to ensure the safety and economy of tunnel engineering.
