Problems solved by technology

However, there are few precedents for BIM modeling of mountain tunnels at home and abroad, and the related technologies are extremely immature, with low accuracy and low efficiency
[0004] In the past, the BIM modeling of mountain tunnels usually borrowed from the BIM modeling method of shield tunnels, and adopted the method of segment splicing, which could not reflect the real situation of mountain tunnels, and the model accuracy was not high

Embodiment

[0043] In this embodiment, by determining some standards for BIM modeling of mountain tunnels, the mountain tunnel is divided into two major parts: the civil model and the electromechanical model, and various software such as AutoCAD, Civil 3D, and Revit are used comprehensively, and plug-ins are written to achieve high modeling efficiency and realize the mountain tunnel fast and detailed modeling.

[0044] Such as figure 1 Shown is the fast and refined BIM modeling method for mountain tunnels disclosed by the present invention. First, refer to the existing municipal engineering BIM modeling standards to determine the BIM modeling standards for mountain tunnels; secondly, create the tunnel centerline in Civil 3D, import it into Revit, and load the outline family for lofting fusion to complete the main civil construction of the tunnel splice the adjacent tunnel sections, adjust the outline rotation angle, and cut off the colliding parts, so that the adjacent tunnel sections, t...

Abstract

The invention relates to a quick and refined mountain tunnel BIM building method. The method comprises the following steps of 1) determining mountain tunnel BIM building standards, and determining a plane graph and an elevation graph of a CAD base graph in a BIM; 2) performing civil modeling of a mountain tunnel by applying Revit and Civil 3D; and 3) determining a cross section mode in combinationthe Civil 3D, and performing electromechanical modeling of the mountain tunnel. Compared with the prior art, the method has the advantages that a set of the mountain tunnel BIM building standards isdetermined by reference to existing municipal engineering BIM building standards, so that the model precision requirements can be ensured; model members are expressed in a classified manner, so that the model information exchange is facilitated; the shortcoming of difficulty in directly creating a spatial curve in the Revit is avoided, and a tunnel center line is marked with mileage by adopting road assembly, so that the tunnel position can be accurately selected; and a tunnel profile assembly mode is created by adopting the Civil 3D, so that a large amount of electromechanical devices can bequickly placed.

Description

technical field [0001] The invention relates to a BIM modeling method, in particular to a fast and refined BIM modeling method for mountain tunnels. Background technique [0002] In recent years, with the country's emphasis on infrastructure, mountain tunnels have received a lot of construction and considerable development. While the construction scale of railway tunnels continues to expand, road tunnels are also increasing at an average annual rate of 350 kilometers. The massive construction of mountain tunnels has promoted the rapid development of technologies in design, construction, and management. A typical example is the application of BIM technology. [0003] The application history of BIM technology in the field of civil engineering is not long, and it is mainly used in visual management, auxiliary design, project operation and maintenance and other fields. The application of BIM in mountain tunnels is still in its infancy. Applying BIM technology to mountain tunn...
