From the software aspect, the application also provides a railway tunnel parametric modeling device for executing all or part of the railway tunnel parametric modeling method, referring to fig. 8, the railway tunnel parametric modeling device specifically comprises the following contents:

The parameterization algorithm application module 10 is configured to form a corresponding railway tunnel parameterization modeling program according to program codes corresponding to general railway tunnel section geometric parameterization algorithm data, where the general railway tunnel section geometric parameterization algorithm data includes: based on the geometric semantic decomposition definition data and parameter definition data of the pre-acquired various railway tunnel outlines, the parameterization algorithm data corresponding to each outline segment in the pre-generated various railway tunnel outlines is obtained.

The embodiment of the device for parameterizing and modeling the railway tunnel provided by the application can be particularly used for executing the processing flow of the embodiment of the method for parameterizing and modeling the railway tunnel in the embodiment, and the functions of the device are not repeated herein, and reference can be made to the detailed description of the embodiment of the method for parameterizing and modeling the railway tunnel.

The part of the railway tunnel parametric modeling device for carrying out the railway tunnel parametric modeling can be executed in a server, and in another practical application situation, all operations can be completed in the client device. Specifically, the selection may be made according to the processing capability of the client device, and restrictions of the use scenario of the user. The application is not limited in this regard. If all operations are done in the client device, the client device may further comprise a processor for specific processing of the parametric modeling of the railway tunnel.

The client device may have a communication module (i.e. a communication unit) and may be connected to a remote server in a communication manner, so as to implement data transmission with the server. The server may include a server on the side of the task scheduling center, and in other implementations may include a server of an intermediate platform, such as a server of a third party server platform having a communication link with the task scheduling center server.

Because the method for the professional parameterization modeling of the railway tunnel still uses BIM modeling software represented by Autodesk Revit and Bentley, CATIA software which are mainstream abroad to carry out secondary development so as to realize the parameterization generation of the tunnel, the method relates to a tunnel BIM parameterization modeling part, all uses the existing abroad commercial software to carry out development, and has great dependence on the commercial software. Meanwhile, in the modeling process, geometric drawing methods such as line segments, curves and the like are used, and if geometric description outside the built-in drawing method is involved, the drawing cannot be directly performed. Therefore, the application example of the application searches the dependency relationship among the structures of the tunnel through the geometric semantics of the railway tunnel, deduces a parameter formula capable of describing the tunnel, realizes the parameterized modeling of the railway tunnel by using codes (such as python, matlab, c++), can get rid of the dependence of foreign software to the greatest extent, and is a key step for realizing the BIM parameterized modeling software of the domestic autonomous railway tunnel.
