Description of the drawings
Fig. 1 is the flow chart of the preferred embodiment of the present invention；
Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and coordinate attached drawing
Detailed description are as follows：
Referring to Fig. 1, a kind of railroad track BIM modeling methods based on up to rope V6 systems, including：
Step 1: based on railway IFC data store standard and IFD railway engineering information model classification and coding standards
Establish railroad track BIM standard elements storehouse；
Step 2: the track skeleton comprising superrelation on curve is created using CAA secondary development modes；
Step 3: determine the spatial position of sleeper and track plates in three dimensions；
Step 4: generate the Ballast track railway roadbed model of different sub-rail foundations and without tiny fragments of stone, coal, etc. rail using CAA secondary development modes
Pedestal, the railway roadbed Slab in road；
Step 5: using CAA secondary development mode by Ballast track railway roadbed model, the pedestal of non-fragment orbit and railway roadbed template die
Type stores standard according to railway IFC and IFD coding standards are converted to BIM models.Wherein：
Step 1 is specially：Standard and IFD railway engineering information model classification and coding standards are stored with railway IFC data
Based on establish railroad track BIM standard elements storehouse
The primary trace type used at present in China railways engineering includes Ballast track, III plate-types of CRTS without tiny fragments of stone, coal, etc. rail
Road, I type double-block type ballastless tracks of CRTS and storehouse line non-fragment orbit etc..Some track components are substantial amounts of in a railway projects
Repeat, such as sleeper, fastener, track plates.Iron can be formed in track BIM using these components as standard element model
Rail road BIM standard elements storehouse.
When the geometry appearance of component is similar, but, it is necessary to establish different standard elements during IFC property value differences.Such as
High speed railway track fastener, the fastener appearance of different model is similar, fastener type is determined by IFC property values, so being directed to
The fastener of different model needs to establish different standard elements.
, it is necessary to the corresponding IFC of routine call when Ballast track railway roadbed, non-fragment orbit pedestal and road bed board is established
Class template adds information to model.So it needs to be established respectively with IFC property sets and IFD sorting code numbers according to IFC classification
Without the IFC class template standard elements of threedimensional model.
Step 2 is specially：The track skeleton comprising superrelation on curve is created using CAA secondary development modes
Track superelevation is designed in railway curve location, is generally realized in a manner that outer rail is raised.In track BIM models
Middle orbit skeleton plays the role of each track component of positioning, it is necessary to realize track superelevation in track skeleton.Utilize CAA bis- times
Exploitation batch selects the circuit three-dimensional center line of each work point, and In-put design superelevation value can generate the track bone containing superelevation
Frame.The track skeleton of generation is mainly included in the rail top among two one steel rail top lines and the rail top surface thus generated and rail top surface
Heart line.
Step 3 is specially：The spatial position of sleeper and track plates is determined in three dimensions
In sleeper standard element and track plates standard element combine track structure height in a model the heart determine one or
Point is forced in two spaces position, is used to position point position is forced to establish coordinate system.Combined circuit superelevation is similary on in-orbit top line
The spatial position of sleeper and track plates is accurately positioned by the way of coordinate system is generated.In-orbit top is determined by reading Excel
The position of the coordinate origin of each sleeper or track plates on line.The X-direction selection tangential direction of coordinate system on rail top line；
The Z-direction selection normal direction of coordinate system.
Step 4 is specially：Using CAA secondary development modes generate different sub-rail foundations Ballast track railway roadbed model and
Pedestal, the railway roadbed Slab of non-fragment orbit
Using track skeleton as input condition, progressively given birth to using CAA secondary development by track skeleton by topological criteria by line
Into face, by adult of looking unfamiliar, pedestal, the road bed board threedimensional model of Ballast track railway roadbed threedimensional model and non-fragment orbit are then generated.
Final only display result of calculation is without intermediate generating process on Model Structure Tree, therefore modeling speed is very fast, model data amount
It is smaller.
It writes the corresponding IFC classes of threedimensional model and property set exactly in XML file, reads XML file according to its content from mark
Corresponding IFC class templates are retrieved in quasi- template library, then by each information standard content of IFC class templates in the form of parameter set
It is added in each physical model.
By the geometric parameter for changing threedimensional model and corresponding IFC classes, can generate suitable for friction speed etc.
Grade, the different Ballast track railway roadbed models of sub-rail foundation and the pedestal of non-fragment orbit and railway roadbed Slab.
Step 5 is specially：Using CAA secondary development mode by Ballast track railway roadbed model, the pedestal and road of non-fragment orbit
Bed board model stores standard according to railway IFC and IFD coding standards are converted to BIM models
Ballast track railway roadbed model, non-fragment orbit pedestal and the railway roadbed Slab of CAA secondary development generation are with parameter set
Form is accompanied with IFC property sets and IFD codings, but there is no classify to create model with IFC.It is deposited to meet railway IFC data
Storage standard searches for corresponding IFC class templates from track BIM standard elements storehouse using CAA secondary development, model is switched to again
IFC class models.
In above preferred embodiment, refer mainly to store standard and the classification of IFD railway engineerings information model with railway IFC data
With railroad track BIM standard elements storehouse is established based on coding standard；It is created using CAA secondary development modes comprising superrelation on curve
Track skeleton；The spatial position of sleeper and track plates is determined in three dimensions；Different rails are generated using CAA secondary development modes
The Ballast track railway roadbed model on lower basis and the pedestal of non-fragment orbit, railway roadbed Slab；There to be the tiny fragments of stone, coal, etc. using CAA secondary development mode
Ballast bed of track model, the pedestal of non-fragment orbit and railway roadbed Slab store standard according to railway IFC and IFD coding standards are converted to
BIM models.This method is suitable for current China mainstream track structure type used being built railway, such as friction speed grade
Ballast track；Different sub-rail foundations, various types of non-fragment orbits, such as I type double-block type ballastless tracks of CRTS, III templates of CRTS
Formula non-fragment orbit and storehouse line non-fragment orbit etc..
It the method achieve and criticized for criterion up to storing standard and IFD coding standards according to railway IFC in rope V6 systems
Quantify to establish the railroad track BIM models with information, be to carry out BIM based on railroad track BIM models to apply such as engineering
Calculation amount etc. is laid a good foundation.Railroad track BIM models are established using this method, not only model geometric precision is high, but also models effect
Rate is high, and model data amount is controllable, and the railroad track BIM projects of hundreds of kilometer are reached suitable for line length.
The embodiment of the present invention is described in detail above, but the content is only presently preferred embodiments of the present invention,
It should not be construed as limiting the practical range of the present invention.Any changes and modifications in accordance with the scope of the present application,
It should all still belong within the patent covering scope of the present invention.
