Problems solved by technology

[0003] First, when the actual tunnel is constructed on a curve, due to the existence of superelevation and overdistance, the actual tunnel centerline and the designed tunnel centerline will not completely coincide. Currently, BIM technology is only used to obtain the designed tunnel centerline for modeling;
[0004] Second, when splicing shield segment rings in the curved section of the tunnel centerline, it cannot effectively adapt to the real situation of the tunnel, and the accuracy of the tunnel model is low

Embodiment Construction

[0056] Such as figure 1 A tunnel BIM rapid modeling method shown includes the following steps:

[0057] Step 1. Draw tunnel plan and tunnel profile:

[0058] Use computer to draw tunnel plan and tunnel longitudinal section in CAD software, and draw shield segment diagram;

[0059] Step 2. Obtain the centerline of the designed tunnel:

[0060] Use the computer to import the drawn tunnel plan and tunnel profile into Civil 3D software, and use the computer to obtain the centerline of the designed tunnel through the "Create Route from Object" tool in the Civil 3D software;

[0061] Step 3. Design the marking label on the centerline of the tunnel:

[0062] Step 301, using a computer to mark a label on the centerline of the designed tunnel through the "Create Road" tool in the Civil 3D software; wherein, the number of labels is multiple, and the distance between two adjacent labels is the ring width of the shield segment;

[0063] Step 40, using a computer to import the design t...

Abstract

The invention discloses a tunnel BIM rapid modeling method. The method comprises the following steps of: 1, drawing a tunnel planar graph and a tunnel longitudinal section graph; 2, acquiring a designed tunnel center line; 3, marking the designed tunnel center line with labels; 4, obtaining the coordinates of labels on a correction tunnel center line; 5, creating a shield segment block; and 6, splicing the shield segments to finish tunnel modeling. The method provided by the invention is simple in step and novel and reasonable in design. According to the tunnel BIM rapid modeling method of theinvention, the coordinates of all the labels on the designed tunnel center line are corrected, so that the method can effectively adapt to the existence of superelevation and over-distance on a bend;segment blocks are corrected when shield segment ring splicing is conducted on the curve section of the tunnel center line, and therefore, the method can effectively adapt to the actual situation ofa tunnel, tunnel model precision is improved, and efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of tunnel BIM modeling, and in particular relates to a fast tunnel BIM modeling method. Background technique [0002] At present, tunnel modeling usually draws on 3D software such as 3DMAX to perform manual typesetting one by one, and does not consider related parameters such as segment correction, and cannot be visualized, so it is difficult to feel the difference. In addition, the modeling efficiency Low, the accuracy is not high. With the development of BIM technology, it is very important to apply BIM technology to tunnels to guide construction, reduce design adjustments, improve construction efficiency, and achieve visual operation and maintenance to ensure engineering safety. Applying BIM technology to tunnel modeling is very important. However, there are still some problems in using BIM technology for tunnel modeling: [0003] First, when the actual tunnel is constructed on a curve, due to the exist...
