Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0038] Before modeling the initial support of the tunnel, it is first necessary to establish the centerline 2 of the tunnel 1 in the 3D modeling software, such as figure 1 As shown in , the center line 2 of the line is used as the position reference for initial support modeling. When it is necessary to change the route direction of the tunnel 1, only the center line 2 of the route needs to be modified, and the initial support model will be automatically updated accordingly.

[0039] The components of the initial support of the tunnel include system anchors, locking foot anchors, sma...

Abstract

The invention discloses a tunnel primary support rapid modeling method which comprises the following steps: step 1, in three-dimensional modeling software, setting related parameters of a certain component in a tunnel primary support, the related parameters comprising a shape parameter and a positioning parameter; 2, establishing a model of a single component in three-dimensional modeling software; 3, packaging and defining the process of establishing the model in the step 2 and the related parameters set in the step 1 as user characteristics, and in the defining process, releasing all the related parameters in the step 1 as modifiable parameters; 4, compiling a knowledge engineering language based on the user characteristics defined in the step 3, so that relevant parameters can be modified and the modeling process in the step 2 can be repeatedly operated; and 5, checking the compiled knowledge engineering language, operating the knowledge engineering language after checking is correct. The components are automatically arranged in the circumferential direction and the longitudinal direction of the tunnel, and therefore rapid modeling of tunnel primary support is completed.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a rapid modeling method for tunnel primary support. Background technique [0002] In engineering practice, although the layout of primary support design and construction modeling has certain rules, it cannot be completed through arrays. In the actual operation of the existing technology, each component of the first ring is usually drawn separately , and then implement the drawing result in a linear array along the line. The main disadvantages are as follows: [0003] (1) There are usually more than ten components in each ring for the initial support of the tunnel, and the drawing workload of more than ten components in the first ring is relatively large. In addition, such components are usually arranged differently in odd and even rings, which almost doubles the workload , the model processing takes a long time; [0004] (2) The line of the tunnel is often not a str...
