Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel design, in particular to a tunnel model construction method and device based on a CATIA platform. BACKGROUND

[0002] In a BIM model of a hydropower station, a large amount of tunnel design needs to be performed, and Boolean operations need to be performed between tunnels and between underground caverns and structures. On a CATIA collaborative design platform, different tunnels belong to different parts, that is, one tunnel corresponds to one part, and one part is one file. For example, when a tunnel section model (BIM model) of a tunnel A (part A) is transmitted to a tunnel B (part B), as shown in FIG. 1, the geometric features in the tunnel section model 110 include five features, that is, an excavation feature 111, an inner passage feature 112, a floor feature 113, a lining feature 114, and a support feature 115. Therefore, at least five features need to be transmitted when the tunnel section model of the tunnel A is transmitted to the tunnel B. Figure 1

[0003] In the related art, each tunnel section model needs to separately publish five features (excavation, inner passage, floor, lining, and support), and when cross tunnels are processed, n tunnel section models x 5 features = 5n times of publishing / reference operations. A large hydropower station project may involve hundreds of such operations, the transmission process is redundant, the operation is complex, and the efficiency is low. SUMMARY

When referencing the first tunnel cross-section model, the entire first tunnel cross-section model is published, eliminating the need to publish each geometric feature in the first tunnel cross-section model separately, thus reducing the number of publishing operations. In the target part area of ​​the CATIA platform, in response to the user's input operation to reference the publishing item of the first tunnel cross-section model to the target tunnel model, the geometric features of the first tunnel cross-section model are parsed to obtain multiple geometric features of the first tunnel cross-section model. After referencing the first tunnel cross-section model to the target tunnel model, the system automatically parses each geometric feature in the first tunnel cross-section model. The invention displays the published items corresponding to the first tunnel cross-section model in the target part area, as well as the marker items corresponding to multiple geometric features of the first tunnel cross-section model. By displaying the published items corresponding to the first tunnel cross-section model and the marker items corresponding to the multiple geometric features obtained from the parsing, the user can directly assemble the geometric features of the first tunnel cross-section model when assembling the first tunnel cross-section model to the target tunnel model. Thus, in the process of referencing the first tunnel cross-section model, this invention publishes and references the entire first tunnel cross-section model, without having to publish and reference each of the multiple geometric features of the first tunnel cross-section model individually, making the referencing process more efficient.

[0056] CATIA platform is a three-dimensional design platform, which is widely used in complex engineering field. In the design of hydropower station tunnel, CATIA supports parameterized modeling and three-dimensional collaborative design, which can efficiently complete tunnel axis optimization, section structure design and excavation support simulation.

[0057] As shown in Figure 2 The tunnel model construction method based on CATIA platform provided by the embodiment of the application comprises the following steps:

[0058] Step S210: In response to a publishing operation of a user on the first tunnel section model, a publishing item corresponding to the first tunnel section model is displayed in a publishing area of the CATIA platform.

[0059] Specifically, in a display interface of the CATIA platform, at least a source part area, a publishing area and a target part area are displayed, wherein the source part area is used to display a part model drawn by the user, the publishing area is used to display a publishing item corresponding to a published part model, and the target part area is used to display a target part model. In some embodiments, the part model can be the first tunnel section model, and the target part model can be the target tunnel model.

[0060] Specifically, the publishing operation of the user on the first tunnel section model displayed in the source part area can be that the user selects the first tunnel section model displayed in the source part area by operating a mouse or other input device, selects to publish the selected first tunnel section model (for example, selects to publish after right-clicking the mouse or selects to publish through a tool in a menu list in the display interface), and names the publishing item in a pop-up dialog box.

[0061] Step S220: In response to an operation of the user inputting to reference the publishing item of the first tunnel section model to the target tunnel model, geometric features of the first tunnel section model are analyzed to obtain a plurality of geometric features of the first tunnel section model.

[0062] Specifically, the first tunnel section model is a BIM model.

[0063] Specifically, in response to the operation of the user inputting to reference the publishing item of the first tunnel section model to the target tunnel model, the user can open the target tunnel model in the target part area, and select the publishing item corresponding to the first tunnel section model in a pop-up file explorer after selecting to reference.

[0064] Specifically, while referencing the first tunnel model, the CATIA platform analyzes the first tunnel model to obtain its geometric features. In one embodiment, the geometric features of the first tunnel cross-section model include at least: excavation features, internal passage features, floor features, lining features, and support features.

[0065] Step S230: Display the publication item corresponding to the first tunnel cross-section model in the target part area, and display the label items corresponding to multiple geometric features of the first tunnel cross-section model.

[0066] Specifically, after referencing the first tunnel cross-section model, in addition to displaying the publication items corresponding to the first tunnel cross-section model in the target part area, it also displays the label items corresponding to multiple geometric features of the first tunnel cross-section model. The label items can be the names of the geometric features. For example, "excavation", "internal passage", "bottom plate", "lining" and "support" are displayed below the first tunnel cross-section model in the target part area.

[0067] In this embodiment, in the source part area of ​​the CATIA platform, in response to the user's publishing operation for the first tunnel cross-section model, the publishing item corresponding to the first tunnel cross-section model is displayed in the publishing area of ​​the CATIA platform. When referencing the first tunnel cross-section model, the entire first tunnel cross-section model is published, eliminating the need to publish each geometric feature separately, thus reducing the number of publishing operations. In the target part area of ​​the CATIA platform, in response to the user's input to reference the publishing item of the first tunnel cross-section model to the target tunnel model, the geometric features of the first tunnel cross-section model are parsed to obtain multiple geometric features of the first tunnel cross-section model. After referencing the first tunnel cross-section model to the target tunnel model, the system automatically parses each geometric feature in the first tunnel cross-section model. The invention displays the published items corresponding to the first tunnel cross-section model in the target part area, as well as the marker items corresponding to multiple geometric features of the first tunnel cross-section model. By displaying the published items corresponding to the first tunnel cross-section model and the marker items corresponding to the multiple geometric features obtained from the parsing, the user can directly assemble the geometric features of the first tunnel cross-section model when assembling the first tunnel cross-section model to the target tunnel model. Thus, in the process of referencing the first tunnel cross-section model, this invention publishes and references the entire first tunnel cross-section model, without having to publish and reference each of the multiple geometric features of the first tunnel cross-section model individually, making the referencing process more efficient. After referencing, the multiple geometric features of the first tunnel cross-section model are automatically parsed, thus not affecting subsequent assembly operations.

[0068] Optionally, such as Figure 3 As shown, Figure 3A schematic diagram of a first tunnel section model of a ZX plane in a tunnel coordinate system is shown, wherein in the tunnel coordinate system, the X axis is the transverse horizontal direction of the tunnel section, the Y axis is the longitudinal direction of the tunnel, and the Z axis (not shown in the figure) is the vertical direction of the tunnel.

[0069] Specifically, as shown in the first tunnel section model, the geometric features of the first tunnel section model are analyzed to obtain a plurality of geometric features of the first tunnel section model, including the following steps: Figure 4

[0070] Step S410: determining a straight line corresponding to the minimum value of the first tunnel section model in the Z axis direction of the tunnel coordinate system to obtain a first straight line.

[0071] Specifically, taking the first tunnel section model shown in the figure as an example, the minimum value in the z axis direction is the first straight line AB. Figure 3

[0072] Step S420: determining two closed loop curves in the first tunnel section model perpendicular to the X axis of the tunnel coordinate system to obtain a first contour line and a second contour line, and determining the excavation feature and the inner channel feature in the first tunnel section model according to the distance relationship between the first contour line, the second contour line and the first straight line.

[0073] Specifically, taking the first tunnel section model shown in the figure as an example, the first tunnel section model includes two contour lines, which are the first contour line ABCDA and the second contour line EFGHE, and the first contour line ABCDA and the second contour line EFGHE are not connected and do not intersect, and can be discretized into two objects, namely the contour ABCDA and the contour EFGHE. Figure 3

[0074] In some embodiments, according to the distance relationship between the first contour line ABCDA, the second contour line EFGHE and the first straight line, the excavation feature and the inner channel feature in the first tunnel section model are determined, including:

[0075] Step S421: determining the shortest distance between the first contour line ABCDA and the first straight line AB to obtain a first distance.

[0076] Step S422: determining the shortest distance between the second contour line EFGHE and the first straight line AB to obtain a second distance.

[0077] Step S423: if the first distance is less than the second distance, the first contour line ABCDA is the excavation feature, and the second contour line EFGHE is the inner channel feature.

[0078] Step S424: if the second distance is less than the first distance, the first contour line ABCDA is the inner channel feature, and the second contour line EFGHE is the excavation feature.​​​

[0079] for Figure 3 As shown in the cross-sectional model of the first tunnel, the shortest distance (first distance) between the first contour line ABCDA and the first straight line AB is less than the shortest distance (second distance) between the second contour line EFGHE and the first straight line AB. Therefore, the first contour line ABCDA represents the excavation feature, and the second contour line EFGHE represents the internal passage feature.

[0080] Step S430: Determine the two endpoints of the first straight line to divide the excavation feature into two contour lines, resulting in the third and fourth contour lines. Based on the length relationship between the third and fourth contour lines, determine the support features in the first tunnel cross-section model.

[0081] Specifically, the two endpoints of the first straight line AB are point A and point B, respectively. The minimum value of the first straight line AB in the X direction is point A, and the maximum value is point B. The excavation feature corresponding to the contour line ABCDA is divided into the third contour line AB and the fourth contour line ADCB by point A and point B.

[0082] Specifically, for the third contour line AB and the fourth contour line ADCB, the contour line with the larger length is the support feature. That is, the support features in the first tunnel cross-section model are determined based on the length relationship between the third contour line AB and the fourth contour line ADCB, including the following steps:

[0083] Step S431: If the length of the third contour line AB is greater than the length of the fourth contour line ADCB, then the third contour line AB is a support feature.

[0084] Step S432: If the length of the fourth contour line ADCB is greater than the length of the third contour line AB, then the fourth contour line ADCB is a support feature.

[0085] for Figure 3 As shown in the cross-sectional model of the first tunnel, it can be seen that the length of the fourth contour line ADCB is greater than the length of the third contour line AB, so the fourth contour line ADCB is a support feature.

[0086] Step S440: Determine the straight line corresponding to the minimum value of the contour line of the inner passage feature in the Z-axis direction of the tunnel coordinate system to obtain the second straight line, and determine the bottom plate feature in the first tunnel cross-section model based on the second straight line and the first straight line.

[0087] Specifically, the line corresponding to the minimum value of the inner passage feature contour line EFGHE in the Z-axis direction of the tunnel coordinate system is the second line GH.

[0088] Specifically, the bottom slab features in the first tunnel cross-section model are determined based on the second straight line and the first straight line, including the following steps:

[0089] Step S441: determining a foot point of one end point G of the second straight line GH on the first straight line, to obtain point a.

[0090] Step S442: determining a foot point of the other end point H of the second straight line GH on the first straight line, to obtain point b.

[0091] Step S443: connecting the end point G and point a to obtain straight line Ga, connecting the end point H and point b to obtain straight line Hb, and connecting point a and point b to obtain straight line ab.

[0092] Step S444: composing the straight line Ga, the straight line Hb, the straight line ab and the second straight line to obtain a contour line GHbaG, to obtain the floor feature in the first tunnel section model.

[0093] Step S450: determining the lining feature in the first tunnel section model according to the excavation feature, the inner passage feature and the second straight line.

[0094] Specifically, the lining feature in the first tunnel section model is determined according to the excavation feature, the inner passage feature and the second straight line, including the following steps:

[0095] Step S451: point a and point b divide the contour line ABCDA corresponding to the excavation feature into line segment aADCBb, and divide the contour line EFGHE corresponding to the inner passage feature into line segment GEFH.

[0096] Step S452: composing the line segment aADCBb, the straight line Hb, the line segment GEFH and the straight line Ga, to obtain the lining feature.

[0097] In the optional embodiment, by extracting the extreme value of the geometric figure in the first tunnel section model, by segmenting the geometric figure through the extreme value, and by judging the distance and length of the segmented figure, each geometric feature in the first tunnel section model can be accurately analyzed.

[0098] As shown in Figures 5(a) and 5(b), Figure 5(a) is a schematic diagram of the source part region 511 and the publishing region 521 when the existing tunnel cross-section model is published with five features alone. In the source part region 511, “Sketch.1”, “Sketch.2”, “Sketch.3”, “Sketch.4”, and “Sketch.5” correspond to the five geometric features of the first tunnel cross-section model. Similarly, the publishing region 521 displays “Sketch.1”, “Sketch.2”, “Sketch.3”, “Sketch.4”, and “Sketch.5”. As can be seen from the prior art, it is necessary to publish each of the five geometric features of the first tunnel cross-section model one by one, that is, publish it five times. Figure 5(b) is a schematic diagram of the target part area 531 corresponding to the case where the five features of the existing tunnel cross-section model are referenced individually. The target part area 531 shows "Sketch.1", "Sketch.2", "Sketch.3", "Sketch.4" and "Sketch.5". As can be seen from the prior art, it is necessary to reference each of the five geometric features of the first tunnel cross-section model one by one, that is, reference it five times.

[0099] As shown in Figures 6(a) and 6(b), Figure 6(a) is a schematic diagram of the source part region 511 and the publishing region 521 corresponding to the published tunnel cross-section model in an embodiment of the present invention. The “Sketch.1” displayed in the source part region 511 corresponds to the first tunnel cross-section model. The publishing region 521 also displays “Sketch.1”, which is the publishing item of the first tunnel cross-section model. It can be seen that in this embodiment of the present invention, only the first tunnel cross-section model needs to be published, that is, published once. Figure 6(b) is a schematic diagram of the target part region 531 corresponding to the referenced tunnel cross-section model in an embodiment of the present invention. The target part region 531 displays “lining”, “excavation”, “internal passage”, “bottom plate” and “support”. It can be seen that in this embodiment of the present invention, only the first tunnel cross-section model needs to be referenced, that is, referenced once, and each geometric feature can be automatically parsed.

[0100] In summary, compared with the prior art, the tunnel model construction method of this invention significantly reduces the number of publications and citations, simplifies the operation, and enables more efficient referencing of tunnel cross-section models.
