Description

Technical Field

[0001] This invention relates to the field of creating three-dimensional tunnel geological models, and specifically to a method for creating three-dimensional tunnel geological models based on Dynamo. Background Technology

[0002] Dynamo is a flow-based visual programming software, now available as a plugin for Revit, used to enable visual programming and parametric component-driven programming. It provides functions such as rapid modeling, parametric design, and batch processing of model information.

[0003] Currently, building tunnel geological models in Revit typically employs traditional modeling methods: creating contour families based on measurement data, determining the road centerline, placing each contour family according to the centerline, and modifying the corresponding parameters. However, irregular contours make modeling extremely tedious, leading to low modeling efficiency, and coarse data processing results in poor model accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a method for creating three-dimensional tunnel geological models based on Dynamo, which greatly improves modeling efficiency and model accuracy.

[0005] The present invention achieves the above objectives by adopting the following technical solution: a method for creating a three-dimensional tunnel geological model based on Dynamo, comprising:

[0006] Step 1: Analyze the design drawings, obtain the coordinate data of each pile, and process the coordinate data of each pile.

[0007] Step 2: Generate the road centerline using the Dynamo program based on the processed stakeout coordinate data;

[0008] Step 3: Create a geological solid model using the Dynamo program based on the road centerline;

[0009] Step 4: Import the geological entity model into the project file and assign corresponding colors and materials to different geological entities.

[0010] Furthermore, in step 1, the step of analyzing the design drawings, obtaining pile-by-pile coordinate data, and processing the pile-by-pile coordinate data using an Excel spreadsheet specifically includes:

[0011] Step 101: Calculate the coordinate data of each pile using the horizontal and vertical curve element tables in the design drawings;

[0012] Step 102: Export the pile-by-pile coordinate data and categorize it in an Excel spreadsheet according to the pile-by-pile coordinate data, X coordinate, Y coordinate, and Z coordinate.

[0013] Step 103: Geologically differentiate the tunnel cross-section data, delineate geological change points, and generate multiple geological Excel spreadsheets.

[0014] It enables data processing for complex geological conditions, such as multi-layered, double-layered, and single-layered geological conditions.

[0015] Furthermore, in step 2, the step of generating the road centerline using the Dynamo program based on the processed stake-by-stake coordinate data specifically includes:

[0016] Step 201: Import the categorized data into the Dynamo program using the Data.ImportExcel node;

[0017] Step 202: Transpose the data using the List.Transpose node, extract the coordinates of the data using the List.Getltemindex node, and generate the point corresponding to the coordinates using the Point.ByCoordinates node.

[0018] Step 203: Connect the points corresponding to the coordinates generated by the PolyCurve.ByPoints node to form a closed loop and generate the road centerline.

[0019] This implementation achieves the conversion of Excel spreadsheet data into data within the Dynamo program, as well as the generation of center lines. It improves the efficiency of both data conversion and center line generation.

[0020] Furthermore, step 3, which involves creating a geological entity model based on the road centerline using the Dynamo program, specifically includes:

[0021] Step 301: Obtain multi-layer cross-sectional data from the geological Excel spreadsheet through the File Path node, import the cross-sectional data into the Dynamo program through the Data.ImportExcel node, transpose the cross-sectional data through the List.Transpose node, and extract the X, Y, and Z coordinates of the cross-sectional data through the List.Getltemindex node; This realizes the conversion of cross-sectional data from the Excel spreadsheet to data in the Dynamo program, improving data efficiency and accuracy.

[0022] Step 302: Group each section data into inverted arch arc data and non-inverted arch arc data using the List.Chop node and List.Getltemindex node. Generate points corresponding to the coordinates of the inverted arch arc data and non-inverted arch arc data using the Point.ByCoordinates node. This achieves grouping of each section data, obtaining inverted arch arc data and non-inverted arch arc data, and generating points corresponding to the coordinates of the data. This grouping process improves data accuracy.

[0023] Step 303: Filter the geological stratification point data using the List.FilterByBoolMask node, and generate points corresponding to the coordinates of the geological stratification point data using the Point.ByCoordinates node; thus realizing the filtering of geological stratification points.

[0024] Step 304: Based on the points corresponding to the coordinates of the non-inverted arch segment arc, generate the non-inverted arch segment arc through the Arc.ByBestFitThroughPoints node; thus realizing the generation of the non-inverted arch segment arc.

[0025] Step 305: Obtain the start and end points of the non-inverted arch arc using the Curve.StratPoint and Curve.EndPoint nodes, and generate the inverted arch arc using the Arc.ByBestFitThroughPoints node and the points corresponding to the inverted arch arc data coordinates; thus realizing the generation of the inverted arch arc.

[0026] Step 306: Using the Curve.SplitByPoints node, the non-inverted arch segment arc and the inverted arch segment arc are broken according to the points corresponding to the geological stratification data coordinates, generating a new arc formed by multiple arc segments; this realizes the breaking of arcs and the formation of new arcs by geological stratification points.

[0027] Step 307: Use the If node to determine the direction of the new arc curve, and use the Curve.Reverse node to unify the direction of the new arc curve; this unifies the direction of the start and end points of the arc.

[0028] Step 308: Extract the new arc starting point through the Curve.StratPoint node, and then use the Line.ByStratPointEndPoint node to divide the geological sections of each section according to the new arc starting point; this achieves the acquisition of each geological section.

[0029] Step 309: Use the PolyCurve.ByJoinedCurves node to form a closed profile of the geological stratification section, use the Python Script node to group the profile in pairs, and use the Curve.SweepAsSolid node to sweep the curve of the closed profile along the road centerline to create a geological solid model.

[0030] Through the above-mentioned refined data processing, a geological entity model was created, and the accuracy of the model was improved.

[0031] Furthermore, in step 4, importing the geological entity model into the project file and assigning corresponding colors and materials to different geological entities specifically includes:

[0032] Step 401: Import the geological entity model into the project file to form an editable family file using the Springs.FamilyInstance.ByGeometry node package;

[0033] Step 402: Split the physical geological entities using the List.Chop node, and assign corresponding color materials to different geological entities using the Element.OverrideColorInView node.

[0034] The beneficial effects of this invention are as follows:

[0035] This invention generates road centerlines and creates geological entity models using the Dynamo program based on processed stake-by-stake coordinate data, thereby improving modeling efficiency and model accuracy.

[0036] This invention utilizes the Dynamo program to process data, which facilitates batch modification of models and modeling of complex geological layers. Attached Figure Description

[0061] Step 302: Group each section data into inverted arch arc data and non-inverted arch arc data using the List.Chop node and List.Getltemindex node.

This grouping process improves data accuracy.

[0062] Step 303: Filter the geological stratification point data using the List.FilterByBoolMask node, and generate points corresponding to the coordinates of the geological stratification point data using the Point.ByCoordinates node; thus realizing the filtering of geological stratification points.
