Description

Technical Field

[0001] The present application relates to the field of tunnel BIM modeling, and specifically to a tunnel BIM intelligent modeling method based on Revit macro programs. Background Art

[0002] The emergence of BIM (Building Information Modeling) technology has set off a new revolution in infrastructure construction. As a new technology, BIM has been deeply studied at home and abroad and applied in large-scale engineering construction. Practice has shown that BIM technology can indeed shorten the construction period, save construction costs, reduce construction risks, and improve the level of construction management. Tunnel design and construction involve a large number of scientific and application fields, and multiple processes overlap with each other, which has high requirements for the rationality of engineering project technology, overall quality, environmental protection and other aspects.

[0003] Although information-based models have been gradually rolled out at home and abroad, the design and construction of large-scale construction projects cannot be separated from BIM. However, the application of BIM in the domestic transportation industry is still in its infancy. Tunnels are the difficulty and pain point of mountain transportation development. Long tunnel BIM models have many structures and components, and the modeling process is complex, the modeling difficulty and workload are large.

[0052] At present, long tunnel BIM models have many structures and components, and the modeling process is complex, with high modeling difficulty and workload. How to quickly and intelligently arrange each tunnel structure and component according to design and construction requirements to replace manual creation of long tunnel BIM models? Considering the changes and needs in each design, construction and operation stage, establishing a tunnel BIM model is not a one-time thing, and changes will occur during design, construction and later maintenance.

[0053] To this end, this solution uses Revit based on macro program visual programming, and with the help of self-encoding macro program, it can directly fit the traffic engineering route in Revit, and use the self-encoding macro program to call the sub-family model to drive the automatic creation of the tunnel BIM model, so that the process of creating the BIM model no longer depends on software such as Civil 3D, reducing the modeling steps, creating sub-family models in parameter form, and using parameter data to drive the formation and adjustment of the tunnel BIM model, automatically improving the attribute content, replacing the existing manual input of attribute content to complete the modeling, and improving the accuracy and efficiency of tunnel BIM modeling.

[0059] In this solution, Revit is the name of a series of software from Autodesk. The Revit series of software is built for Building Information Modeling (BIM), which helps architects design, build and maintain better quality and more energy-efficient buildings. Self-encoded macros are used to assist Autodesk Revit in doing things that cannot or are difficult to achieve on the current platform. Self-encoded macros are visual scripting programs that help users define algorithms to process data and generate geometric graphics.

[0060] In order to meet the construction and management functions of the tunnel project throughout its life cycle, reference Figure 2 , Figure 2 A flowchart of the steps of the tunnel BIM intelligent modeling method based on the macro program of Revit in the embodiment of the present application is shown, and the method may include the following steps:

[0061] Step S101: According to the pre-collected tunnel horizontal curve data and vertical curve data, the three-dimensional tunnel line is fitted in Revit.

[0062] In the specific implementation process, horizontal curve refers to the general term for curves at the turning point of the route in the plane line; vertical curve refers to the curve connecting two adjacent slope sections on the longitudinal section of the line with the slope change point as the intersection point; the three-dimensional line of the tunnel is directly obtained through operations in the Revit software.

[0063] Step S102: extracting the geometric features of each main structure of the tunnel and its subsidiary components, parametrically creating a sub-family model of each main structure and its subsidiary components in Revit, and setting the adjustable parameters of the corresponding sub-family model according to the geometric features to obtain a tunnel modeling family library; wherein, when modifying the adjustable parameters of any sub-family model, the geometric dimensions of the sub-family model in the tunnel modeling family library are adaptively modified.

[0064] In the specific implementation process, the main structure of the tunnel refers to the building built underground or underwater or in the mountain, where railways are laid or roads are built for motor vehicles to pass. It mainly includes lining, and concrete is commonly used as the material for the lining. There are also sprayed anchor mesh structures as lining. The auxiliary components of the tunnel generally include drainage facilities, lighting facilities, ventilation facilities and safety avoidance facilities. The purpose of building auxiliary components is to ensure the safe passage of vehicles in the tunnel and to ensure the normal use of the tunnel. Adjustable parameters are parameters that can be modified according to actual design requirements. Geometric features refer to the characteristics used to generate geometric figures. The tunnel modeling family library contains multiple sub-family models.

[0065] Step S103: According to different tunnel BIM model information requirements, targeting the characteristics of different main structures and their auxiliary components and engineering overviews, the family file name, pile number parameters, size parameters and attribute content of each sub-family model in the tunnel modeling family library are batch defined in an EXCEL table.

[0066] In the specific implementation process, the family file name of the sub-family model includes: secondary lining, anchor rod, steel bar and primary lining; the size parameters include the secondary lining longitudinal slope, anchor rod length, steel mesh specifications, etc., and the pile number parameters include the pile number code. It should be noted that the pile number parameters and size parameters defined here do not include actual values.

[0067] Step S104: using a self-encoding macro program to call multiple target sub-family models required for the three-dimensional line of the tunnel, and modifying the size parameters of the target sub-family models in an EXCEL table so that the target sub-family models match the three-dimensional line of the tunnel in the macro program, and constructing a tunnel BIM model.

[0068] In the specific implementation process, the self-encoded macro program is obtained through secondary development and is used to call the target sub-family model. The target sub-family model is any sub-family model among the multiple sub-family models corresponding to each main structure and its auxiliary components. After modifying the size parameters of the target sub-family model, the multiple target sub-family models with modified size parameters are combined to obtain the actual required tunnel BIM model.

[0069] This solution aims to solve the problems of long tunnel BIM models with many structures and components, complex modeling process, difficulty and workload. Through Revit macro-based visual programming, and with the help of self-encoding macros, traffic engineering routes can be directly fitted in Revit. The self-encoding macros are used to call sub-family models to drive the automatic creation of tunnel BIM models, so that the process of creating BIM models no longer depends on software such as Civil 3D, reducing the steps of modeling, creating sub-family models in parameter form, and using parameter data to drive the formation and adjustment of tunnel BIM models, automatically improving attribute content, replacing the existing manual input of attribute content to complete modeling, and improving the accuracy and efficiency of tunnel BIM modeling. Furthermore, batch definition of attributes can not only define the attributes of the family according to project needs, but also no longer rely on manual definition by modeling workers, improving the informationization capabilities of tunnel BIM and further increasing the efficiency of tunnel BIM modeling.

[0070] In the present application, the implementation steps of fitting the three-dimensional line of the tunnel in Revit according to the preset collected tunnel horizontal curve data and vertical curve data in step S101 may include:

[0071] Step S101-1: Calculate plane coordinate data according to preset collected tunnel plane curve data;

[0072] Step S101-2: Fitting the plane coordinate data and the preset vertical curve data into a three-dimensional curve in Revit by using the least squares method to obtain the three-dimensional line of the tunnel.

[0073] Wherein, step S101-1 can be specifically implemented by the following steps:

[0074] Step S101-1-1: determining the linear characteristics of the tunnel horizontal curve according to the horizontal curve data;

[0075] Step S101-1-2: According to the linear features of the three-dimensional curve, the plane curve data is calculated by using the intersection method or the line element method to obtain the plane coordinate data.

[0076] Among them, when the intersection method is used to calculate the horizontal curve data, the following horizontal curve data can be obtained from the "Horizontal Curve Element Table" in the line design: starting coordinates, intersection curve elements and end point coordinates, the intersection curve elements include intersection coordinates, curve radius, front easement curve length, and rear easement curve length; the starting coordinates are QD starting point coordinates or previous intersection coordinates JD; the end point coordinates are end point coordinates or rear intersection coordinates JD. The horizontal curve data fitted by the intersection method can be shown in Table 1.

[0077] Refer to Table 1, which shows the flat curve data obtained by fitting the intersection method.

[0078] Table 1 Flat curve data fitted by intersection method

[0079]

[0080] When the horizontal curve data is calculated using the line element method, the following horizontal curve data can be obtained from the "Horizontal Curve Element Table" in the line design: the line type, starting point coordinates, starting azimuth, starting radius, ending radius, deflection direction and line element length of each line segment. The horizontal curve data fitted using the line element method are shown in Table 2.

[0081] Table 2 Flat curve data fitted by line element method

[0082]

[0083]

[0084] As for the choice of intersection method or line element method, in general, the intersection method is mainly applicable to symmetrical or asymmetrical transition curves and circular curves. Therefore, when the line characteristics of the tunnel flat curve meet the transition curve and circular curve, the intersection method can be used to extract the tunnel flat curve data from the flat curve element table in the line design; on the contrary, when the line characteristics of the tunnel flat curve meet the front transition curve, the length of the rear transition curve is 0 or the three-unit curve, the line element method should be used. In addition, according to the line characteristics of the tunnel flat curve, when the line type of the tunnel flat curve is relatively uncomplicated and the data supports it, the intersection method can be used to fit the required line faster; when the tunnel flat curve is more complex, the line element method is more applicable.

[0085] In the present application, the vertical curve data in step S101-2 can be extracted from the pre-obtained line design "slope table", and the vertical curve data can include the slope change mileage, slope change elevation and vertical curve arc length, wherein the vertical curve arc length is the vertical curve arc radius in the circular curve type, or the parabola length in the parabola type. The extracted vertical curve data can be shown in Table 3.

[0086] Table 3 Vertical curve data

[0087]

[0088] In this application, as far as step S101-2 is implemented, the program module can be developed in Revit with the help of the line fitting principle method, and the plane coordinate data and the vertical curve data are fitted with a three-dimensional curve by the least squares method to obtain the three-dimensional line of the tunnel. Least squares approximation is a commonly used numerical approximation fitting method. When the approximation fitting function is a polynomial, it is a polynomial function approximation, and the fitting of the three-dimensional curve needs to be implemented with the least squares method-polynomial fitting function. Among them, the least squares curve fitting process is to calculate the interpolation square sum of the plane coordinate data and the function fitting value to reach the minimum as the best fitting result. This calculation formula can refer to the relevant existing technology and will not be elaborated here.

[0089] In the present application, the parametric creation of the sub-family model of each main structure and its attached components in Revit in step S102 may include the following steps:

[0090] Extract multiple elements of each main structure and its attached components in Revit, and set basic parameters between different elements in the multiple elements;

[0091] In the specific implementation process, the primitive generally refers to the basic graphic element. Any graphic expression is composed of a number of different points, lines, surface patterns or the same pattern cycle combination. These points, lines, and surface patterns are the basic graphic elements. Setting the basic parameters of the primitive can increase the geometric connection between multiple sub-family models.

[0092] The basic parameters are associated in the form of data to obtain the sub-family model of each main structure and its auxiliary components created parametrically.

[0093] In the specific implementation process, the basic parameters are associated in the form of data to facilitate the control and management of the parameters of the sub-family model, so that when the adjustable parameters of any sub-family model are subsequently modified, the geometric dimensions of the sub-family model in the tunnel modeling family library are adaptively modified.

[0094] As shown in the above scheme, in the BIM modeling process, it is difficult to quickly and accurately create the size, angle, relative coordinates and other elements of the sub-family model of the main structure and its auxiliary components. The parametric creation method in the above steps is used to associate the relevant elements in the BIM model, and set the attributes of the sub-family model size, angle, relative coordinates and other elements, that is, the sub-family model can be created and modified in the form of parameters. By writing formulas or associating element parameters with conditional language to meet certain geometric and quantitative relationships, they restrict each other. In order to modify one of the element parameters, the associated related parameters will change together, thereby achieving the function of quickly modifying the BIM model.

[0095] In this application, the process of parameterizing and creating a subfamily model is described in detail with reference to the following examples:

[0096] For example, a parameterized model is established for the lining body, wherein the lining body includes a secondary lining and a primary lining.

[0097] In the specific implementation process, the secondary lining is modeled parametrically. The inner and outer contours of the tunnel secondary lining are mainly composed of five-center circle arcs that are tangent to each other. In the drawing process, it is first necessary to use the size parameters to find the relative coordinates of the fixed center of the circle, and use the fixed center of the circle to draw the corresponding arc. The length of the arc is controlled by the angle to achieve the purpose of the five arcs being tangent and non-conflicting. The five arcs are associated through geometric constraints and size constraints to make the degrees of freedom and constraints equal. In different secondary linings, only static values ​​or formulas need to be adjusted to complete the drawing of the secondary lining contour, thereby meeting the contour requirements of various lining types. After establishing a contour system that can be driven by parameterization, the lofting, stretching, fusion, and shearing operations are implemented according to the spatial creation function of the modeling, and then different three-dimensional lining Revit family models are created.

[0098] Specifically, the inner contour of the tunnel is mainly centered at five fixed points with radius r 1 To r 4 Draw an arc at a certain angle to form the inner contour, R 1 To R 4 Draw the outer contour at a certain angle; create an 1 (0, 0) is the relative coordinate system of the center of the circle, find O 2 (X 2 , Y 2 ), O' 2 (-X 2 , Y 2 ), O 3 (X 3 , Y 3 ), O' 3 (-X 3 , Y 3 ) and the center of the invert O' 4(0, Y 4 ) Draw arcs with their respective radii and angles according to the center point positions in the design drawings, and lock the tangent geometric relationship, so that the inner circle contour can be drawn in a parametric way. The five-center circle outer contour Ri is calculated and drawn based on the geometry and value of the radius of the tunnel inner contour. The calculation implementation formula is as follows:

[0099] R i =r i +L

[0100] Where r i is the radius length of the inner contour with the same center, and L is the lining thickness value.

[0101] Refer to Table 4, which shows the adjustable parameters of the secondary lining profile.

[0102] Table 4 Adjustable parameters of the secondary lining profile

[0103]

[0104]

[0105] Further create a standard family template file through Revit, create a reference line in the coordinate center of the standard family template, and set the length dimension parameters and longitudinal slope angle parameters. Use the reference line as the standard layout path, insert the outline of the lining sub-family model to be modeled for layout, and by setting the length dimension parameters and longitudinal slope angle parameters of the layout, you can enter relevant parameters to adjust the length and longitudinal slope of the secondary lining.

[0106] Refer to Table 5, which shows the adjustable parameters of the standard family template.

[0107] Table 5 Adjustable parameters of the second lining standard family template

[0108]

[0109] Furthermore, referring to the above steps of parameterizing and modeling the secondary lining, parameterize and model the primary lining.

[0110] A parametric model is established for the supporting components in the tunnel, which mainly include anchor rods, steel arch frames and grilles.

[0111] In the specific implementation process, the size of the designed anchor rods and their effective positions in the tunnel vary according to the tunnel surrounding rock grade and construction plan, and the forms of the steel arches and grilles also vary.

[0112] Specifically, in the process of parametric modeling of anchor rods, there are differences in diameter, length and number of anchor rods used in various lining types, and the anchor rods act on the arch and the side wall.

[0113] In the process of establishing the anchor rod parameter model, first create a new standard family template, set a single anchor rod reference line as the anchor rod layout path in the standard family template file, set the anchor rod layout length as an instance parameter, and mark the anchor rod radius as the profile parameter in the layout profile. In tunnel modeling, the modeling of anchor rod subfamilies with different lengths and radii can be completed by adjusting the parameters. In order to make the anchor rod model more in line with the actual application of the project, an anchor plate is set at the bottom of the anchor rod.

[0114] Refer to Table 6, which shows the adjustable parameters of the anchor standard family template.

[0115] Table 6 Adjustable parameters of anchor standard family template

[0116]

[0117] Different from other supporting components placed in vertical arrays along the tunnel direction, anchors are arranged at certain angles and spacings in the design of tunnel anchor support to achieve better mechanical effects. Therefore, when drawing the anchor subfamily model, the curve array modeling function is used, and the angle of the anchor staggered and the number of arrays are generally adjusted by designing size parameters to meet the design and construction standards.

[0118] Furthermore, in the tunnel support components, the steel arch frame and the grille are vertically distributed along the tunnel direction. The modeling process is basically consistent with the establishment principle and method of the above-mentioned anchor subfamily model, which will not be elaborated here.

[0119] The rest of the tunnel structures are modeled parametrically.

[0120] In the specific implementation process, according to the design standards and use requirements of the tunnel, the tunnel also contains some conventional structures and rail transit pavement structures. In the actual design and construction, the tunnel construction limits and inner contours have not changed. The conventional structures inside have no size and structural changes, and the auxiliary structures have no obvious geometric parameter characteristics, and do not have universality and secondary utilization value.

[0121] In the actual BIM modeling process of the tunnel, after confirming that the tunnel structure design and construction drawings are correct, the AutoCAD file is imported into Revit, and the inner and outer contours of the remaining tunnel structures are created by picking lines, and the closed graphics are used to realize the lofting to form the structural geometry. In addition, the longitudinal slope and lofting length and other parameters are set in the same way as the parametric establishment of the second lining sub-family model mentioned above to realize the parametric modeling of sub-family models such as cable trenches, drainage ditches, invert backfill, tracks, ballast and open-cut tunnel portals. The created sub-family models are exported and saved by classification and naming to form a tunnel modeling family library for calling when building the BIM model.

[0122] In this application, step S103 specifically includes the following contents:

[0123] S103-1: extracting a standard family template in Revit, wherein the standard family template includes a plurality of inherent properties to be written and a plurality of adjustable properties to be written;

[0124] S103-2: according to different tunnel BIM model information requirements, and targeting the characteristics and engineering overviews of different main structures and their auxiliary components, a plurality of the adjustable attributes are set, and the plurality of the adjustable attributes are written in text form in an EXCEL table;

[0125] S103-3: Implementing attribute definitions of the plurality of adjustable attributes in the EXCEL table, wherein the content of the attribute definition includes the family file name, pile number parameters, size parameters and attribute content of each sub-family model in the tunnel modeling family library.

[0126] In the specific implementation process, it is necessary to set the adjustable parameters of the standard family template in Revit to parameterize the creation of sub-family models, so that when the adjustable parameters of any sub-family model are modified later, the geometric dimensions of the sub-family model in the tunnel modeling family library can be adaptively modified, thereby making the creation of BIM models more convenient and quick.

[0127] This solution quickly and batch-defines the properties of each sub-family model for the tunnel BIM model family components. In the batch definition process, the attribute types that need to be defined for the sub-family model are counted in the EXCEL table according to each family file name, and the attribute content set in the tunnel BIM modeling family library and the EXCEL table is read by writing code blocks to realize the attribute definition of the sub-family model. In the attribute writing process, this solution considers the display and sharing of attribute information, and uses the Select BuiltlnParameter Group node block to divide the attributes to be defined into IFC attribute parameters to meet the model attribute interaction.

[0132] In the specific implementation process, first create a tunnel standard family template in Revit, and load the parametrically created tunnel modeling family library into the project file.

[0133] The data of modeling parameters are based on the tunnel design and construction drawings, and the lining types corresponding to the pile number parameters are counted. The sub-family models corresponding to the pile number parameters are recorded in an Excel table, and the attribute content of the sub-family models defined in batches during the parametric modeling process is filled in the table. If the size parameters in the sub-family model need to be changed, the content in the EXCEL table file is also read through the self-encoded macro program node.
