Embodiment 1

[0018] Such as figure 1 Shown: A method of excavation and support of loess tunnel based on BIM technology, including the following steps:

[0019] Step 1. Apply BIM technology to create a 3D visualization model of the tunnel;

[0020] Step 2. After passing the data review in step 1, conduct tunnel earthwork excavation simulation and support simulation based on BIM technology;

[0021] Step 3. After the results in step 2 are qualified, make videos of construction procedures such as earthwork excavation and support, and organize technical disclosure according to BIM construction simulation, carry out construction, and dynamically adjust.

[0022] in:

[0023] The three-dimensional visualization model of the tunnel described in step 1 includes tunnel length, width, height, and curvature.

[0024] The earthwork excavation simulation described in step 2 includes surveying and setting out, excavation machinery, excavation steps, earthwork transportation, and construction time.

Abstract

The invention discloses a loess tunnel earth excavation and support method based on a BIM technology. The loess tunnel earth excavation and support method based on the BIM technology comprises the following steps: building a tunnel visualization model through employing the BIM technology, and carrying out tunnel earth excavation simulation and support simulation based on the BIM technology; and making construction process videos of earth excavation, supporting and the like, organizing technical disclosure according to BIM construction simulation, and performing construction. The tunnel construction efficiency can be improved; and problems possibly occurring in construction can be predicted in advance, so that the problems are solved in advance, the construction scheme is optimized or readjusted, rework is avoided, the engineering cost is reduced, the construction period is shortened, and good social benefits and economic benefits are obtained.

Description

technical field [0001] The invention belongs to tunnel construction methods in highway engineering, and in particular relates to an earthwork excavation and support method for loess tunnels based on BIM technology. Background technique [0002] At present, with the rapid development of highway engineering in our country, there are more and more tunnels passing through mountains, and more and more tunnels passing through the loess area in the west. Tunnel construction includes earthwork excavation, support and other work. There are many procedures, the construction organization is easy to be confused, and safety accidents are very likely to occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an earthwork excavation and support method for loess tunnels based on BIM technology. [0004] In order to solve the above-mentioned technical problems, the inventor obtained the technical solution of the present invention...
