[0044] D. Real-time display of the current tunnel substructure cross section design results;

[0045] E. Update the tunnel substructure cross section database.

[0046] Step A creates a tunnel substructure cross section database, the specific process is as follows:

[0047] First, the tunnel substructure cross section database is composed of multiple tunnel substructure cross section objects;

[0048] Then, determine that each tunnel substructure cross section object is composed of four parts.

[0049] The cross section object is composed of four parts: track structure cross section name, track structure type, tunnel inner surface type, and indefinite length array for storing cross section size parameter structure object.

[0050] Step B creates a tunnel substructure cross section prototype template database, the specific process is as follows:

[0051] The tunnel substructure cross section prototype template database has the same structure as the tunnel substructure cross section database, that is, the cross section prototype template database is composed of multiple tunnel substructure cross section objects.

[0052] In the cross section prototype template database, the track structure type of each cross section object is different, and in the cross section database, the track structure type of different cross section objects can be the same.

[0053] Step C interactively modifies the current tunnel substructure cross section object, the specific process is as follows:

[0054] First, based on the cross section database, the cross section object is interactively modified;

[0055] Then, based on the cross section prototype template database, the cross section object is interactively modified.

[0058] Then, extract the cross-section object of the current tunnel track structure from the tunnel track structure cross-section database;

[0059] Then, traverse the indefinite-length array member of the cross-section object for storing cross-section dimension parameter structure object;

[0060] Later, display the parameter value and parameter name of all cross-section dimension parameter structure objects in the interactive interface;

[0061] Finally, modify the dimension parameter value according to the parameter name.

[0062] Based on the cross-section prototype template database, the interactive modification of the cross-section object is carried out, and the specific process is as follows:

[0063] Firstly, extract all track structure types from the cross-section prototype template database of the tunnel track structure;

[0064] Then, select a track structure type different from the track structure type of the current cross-section object;

[0065] Later, with the newly selected track structure type as the index, extract and replace the cross-section dimension parameter value and parameter name currently displayed in the interactive interface from the cross-section prototype template database of the tunnel track structure.

[0066] Step D displays the cross-section design results of the current tunnel track structure in real time, and the specific process is as follows:

[0067] Firstly, compile a tunnel inner contour modeling function, and the modeling function takes the tunnel inner surface type and the indefinite-length array for storing cross-section dimension parameter structure object as input to create a tunnel inner contour model in two-dimensional or three-dimensional space;

[0072] Then, the latest member data is extracted from the current tunnel understructure cross-section object, and according to the tunnel inner surface type of the current understructure cross-section object, a tunnel inner contour drawing function is called;

[0073] Then, according to the understructure type of the current understructure cross-section object, an understructure contour drawing function is called.

[0074] Then, the above two functions are inputted with an indefinite length array for storing the cross-section size parameter structure object.

[0075] Finally, the two-dimensional or three-dimensional understructure design result and the relationship between the understructure design result and the tunnel inner contour are displayed in real time in the interactive interface.

[0076] Specifically, step E updates the tunnel understructure cross-section database, and the specific process is as follows:

[0077] As a way, the current understructure cross-section object is inserted into the tunnel understructure cross-section database.

[0078] As another way, the current understructure cross-section object is used to replace the cross-section object with the same understructure cross-section name in the tunnel understructure cross-section database.

[0079] As another way, the current understructure cross-section object is used to replace the cross-section object with the same understructure cross-section name in the tunnel understructure cross-section database.

[0080] The tunnel understructure cross-section interactive design method of the present application creates a tunnel understructure cross-section database, creates a tunnel understructure cross-section prototype template database, interactively modifies the current tunnel understructure cross-section object, displays the current tunnel understructure cross-section design result in real time, and updates the tunnel understructure cross-section database.
