[0009] Based on the above technical solution, further, in step 2, the generation of the toe board control line includes three methods: the first is to generate the toe board control line by clicking on the screen; the second is to automatically read and transfer the toe board control line data of the built toe board three-dimensional model by data transmission; the third is to import the toe board control line data file.

[0010] Based on the above technical solution, further, in step 3, the process is: step 31, select the type of joints of the anti-seepage panel, wherein the types of joints are tension joints and compression joints; step 32, set the joint parameters of the anti-seepage panel, wherein the input parameters of the tension joints include the number of tension joints, tension spacing and vertical turning distance; the input parameters of the compression joints include the number of compression joints, compression joint distance and compression joint width; step 33, perform joint and block operations on the anti-seepage panel in sequence from the bottom line end point of the left bank wave-breaking wall to the bottom line end point of the right bank wave-breaking wall; step 34, complete the setting of the anti-seepage panel joints, and calculate the width of the last panel.

[0011] Based on the above technical solution, further, the calculation process in step 34 is: according to t i =t 0 +bh i Dynamically and automatically calculate the thickness of each non-uniform panel; where t i is the bottom thickness of the i-th panel; h i is the height of the i-th panel.

[0012] Based on the above technical solution, further, in step 4, a three-dimensional block model of the anti-seepage panel is created according to the data input in steps 1 to 3, and each block model is numbered from left to right.

[0013] Based on the above technical solution, further, in step 5, the operation process is: Step 51: determine the reinforcement type of the anti-seepage panel; wherein, the anti-seepage panel reinforcement type includes single-layer bidirectional and double-layer bidirectional reinforcement types; Step 52: select the reinforcement position; wherein, the anti-seepage panel reinforcement position includes upper steel bars and lower steel bars; Step 53: preset reinforcement principles; wherein, including setting the axial and slope steel bar style, diameter, spacing and protective layer thickness of the anti-seepage panel respectively; Step 54: generate a three-dimensional reinforcement principle, and perform reinforcement processing based on the parameters.

[0014] Based on the above technical solution, further, in step 6, the operation process is: step 61, select the block panel and determine the cutting position; step 62, generate the two-dimensional reinforcement diagram of each block panel one by one or in batches; wherein, the two-dimensional reinforcement diagram includes the anti-seepage panel plan view, the surface layer steel bar plan view, the bottom layer steel bar plan view and the typical cross-sectional view of each cutting position.

[0032] The present invention is further described and illustrated below in conjunction with the accompanying drawings and specific embodiments. The technical features of each embodiment of the present invention can be combined accordingly without conflicting with each other.

[0033] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and easy to understand, the specific implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The technical features in each embodiment of the present invention can be combined accordingly without conflicting with each other.

[0034] In the description of the present invention, it is to be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or indirectly connected, that is, there are intermediate elements. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0035] Example 1

[0036] Combination Figure 1 As shown, this embodiment provides a three-dimensional design method for an anti-seepage panel of a concrete panel rockfill dam, comprising the following steps:

[0037] Step 1. Set the design benchmark information parameters of the anti-seepage panel. It should be noted that the design benchmark information parameters of the anti-seepage panel set in this step are the basic data support for the entire three-dimensional design method; these benchmark information parameters will run through the subsequent steps and provide necessary limitations and basis for the specific operations of each step. Step 1 provides basic data and parameters for the entire design system to ensure the accuracy and reliability of the design work; the toe board control line generation is used to interactively generate the spatial position of each toe board control line of the toe board, and the toe board control line is generated by screen selection, data transfer and manual import technology, and stored in the database; this step provides a variety of ways to generate toe board control lines to meet different design needs and data source requirements.

[0038] Reference Figure 2 As shown, the specific process includes the following steps:

[0039] Step 11: First, set the graphic space coordinate system and select the visualization model range, which lays an accurate spatial foundation for subsequent design work, so that subsequent design operations have a unified spatial reference standard, ensuring that all design elements can be positioned and displayed in the correct coordinate system.

[0040] Step 12: Pick up the design baseline of the anti-seepage panel and set the corresponding design parameters. There are two ways to determine the design baseline of the anti-seepage panel: the first is to select the bottom line of the concrete panel rockfill dam wave wall and set the corresponding elevation value Z 0The second method is to select the axis of the concrete face rockfill dam and set the corresponding dam crest elevation Z 1 , the horizontal distance Hdis from the dam axis to the bottom line of the wave-breaking wall, the vertical distance ΔH from the dam top elevation to the bottom line of the wave-breaking wall, and the upstream direction. Through the above two methods, the design baseline of the anti-seepage panel can be flexibly determined to prepare for further improvement of the anti-seepage panel design to meet the needs of different projects.

[0041] Step 13: Set the design parameters of the anti-seepage panel. After completing the setting of the graphic space coordinate system and the selection of the anti-seepage panel design baseline, further set the specific design parameters of the anti-seepage panel, such as the panel bottom slope, panel initial thickness, and panel thickness coefficient. Among them, the anti-seepage panel design parameters include the panel bottom slope m 0 , i.e. the slope coefficient of the bottom surface of the anti-seepage panel; the initial thickness of the panel t 0 , that is, the thickness of the top of the panel, in cm, not less than 30cm; the panel thickness coefficient b, that is, the thickness variation coefficient of the anti-seepage panel, 0.002≤b≤0.004, when the anti-seepage panel is a panel of equal thickness, b=0. By clarifying these parameters, the parameterization of the anti-seepage panel design is realized. With this parameterization method, the design can be quickly adjusted and optimized to achieve the consistency and standardization of the design. At the same time, it also improves the flexibility of the design in the face of different engineering situations, making the entire anti-seepage panel design more scientific, reasonable and adaptable to various engineering needs.

[0042] It should be noted that the three steps from step 11 to step 13 are carried out in sequence from the construction of the overall spatial layout foundation, to the determination of the design baseline of the anti-seepage panel, and then to the setting of specific anti-seepage panel design parameters. The previous step provides the necessary basis and conditions for the next step, and together they constitute a relatively complete logical framework of the relevant design process.

[0043] Step 2: Generate the toe plate control line and set the starting point and end point of the toe plate control line of the riverbed section.

[0044] Reference Figure 3 As shown in the figure, there are three ways to generate the toe board control line: the first is to generate the toe board control line by screen selection, which is intuitive and convenient. Designers can accurately select the toe board control line on the screen according to the actual situation to generate the toe board control line; the second is to automatically read and transfer the toe board control line data of the built toe board three-dimensional model through data transmission, making full use of existing data resources and improving design efficiency; the third is to import the toe board toe board control line data file, which provides more flexibility for design. Furthermore, by setting the starting point and end point of the toe board control line of the riverbed section, the scope of the toe board control line in the riverbed section is clarified, which is convenient for the subsequent seam and block and reinforcement design of the slope section and riverbed section panels.

[0045] In this embodiment, the toe board control line in step 2 is the anti-seepage panel baseline "Y" line. The "Y" line is the intersection of the bottom surface of the anti-seepage panel and the downstream slope of the toe board. When the dam axis and the toe board line are determined, the "Y" point connection line is unique. At the same time, the toe board control line generated in step 2 takes the bottom line endpoint of the left bank wave wall as the starting point Y of the toe board control line. 1 , the bottom line end point of the right bank wave wall is the end point of the toe board control line Y i (i=1,2,3......n, n is an integer).

[0046] Step 3: Perform parametric seam and block processing on the anti-seepage panel and calculate the panel width.

[0047] Reference Figure 4 The specific process includes the following steps:

[0048] Step 31, first select the type of joints for the anti-seepage panel. The joint types are tension joints and compression joints. Tension joints can be set in the bank slope section of the panel, and compression joints can be set in the riverbed section. Different joint types are designed to be suitable for different stress conditions and deformation characteristics. Tension joints can provide expansion and contraction space for the panel due to temperature reduction, so that the panel can shrink freely, avoid cracks due to excessive tensile stress, ensure the structural integrity of the panel, adapt to the tensile deformation of the panel caused by uneven foundation settlement, and prevent cracks between the panel and the foundation due to uncoordinated deformation. It can also be used as a structure to release the tensile stress of the panel concrete hardening shrinkage, so that the panel has space to shrink during the shrinkage process, reducing the possibility of cracks; compression joints can provide a certain compression space for the panel, so that the panel can produce appropriate deformation under the action of water pressure, evenly distribute the pressure within a certain range, avoid local excessive compressive stress and damage to the panel, and can also adapt to the compression deformation of the panel caused by the deformation of the rockfill body, ensuring that the panel can withstand the reaction force of the rockfill body without being damaged. Therefore, it can meet the different joint requirements of the bank slope section and riverbed section of the anti-seepage panel.

[0049] Step 32, setting the anti-seepage panel joint parameters, wherein the tension joint joint input parameters include the number of tension joints, tension spacing and vertical turning distance; the compression joint joint input parameters include the number of compression joints, compression joint distance and compression joint width. The reasonable setting of these parameters is crucial to controlling the deformation and crack generation of the anti-seepage panel. The parametric joint design enhances the flexibility and scalability of the design and improves the design efficiency.

[0050] Step 33: The anti-seepage panel is split and divided into blocks from the bottom line end point of the left bank wave-breaking wall to the bottom line end point of the right bank wave-breaking wall. The split and block are performed in a certain order to ensure the rationality and consistency of the design.

[0051] Step 34: Complete the anti-seepage panel joint setting and calculate the width of the last panel. i =t 0 +bh i Dynamically and automatically calculate the thickness of each non-uniform panel, where t i is the bottom thickness of the ith panel; h i is the height of the ith panel. The realization of non-uniform panel thickness makes the panel thickness design more in line with actual engineering needs.

[0052] In this embodiment, in step 3, the joints and blocks of the anti-seepage panel can be added or reset, and the joints and blocks can be automatically judged whether they reach or leave the riverbed section, and prompts and automatically deletes the redundant joint settings, which improves the flexibility and accuracy of the design. In step 3, the compression joint is set with a construction joint width, and the set joint width has been deducted when calculating the final panel width, which improves the accuracy of the design. In step 3, the control line of the toe plate and the tension joint are represented by vectors respectively. For the toe plate, the key control node is selected to calculate and determine its edge vector and surface normal vector; for the tension joint, the starting point and direction vector are determined, and the position and direction of the tension joint are represented in the form of vectors. By establishing the corresponding rotation matrix and translation matrix, the rotation matrix is ​​used to adjust the direction of the vector, and the translation matrix is ​​used to change the position of the vector. These matrices will be used to adjust the position and direction of the tension joint. The rotation matrix is ​​applied to rotate the direction vector of the tension joint so that it is gradually adjusted in the direction perpendicular to the toe plate surface. By continuously adjusting the parameters of the rotation matrix, the angle between the direction vector of the tension joint and the surface normal vector of the toe plate is gradually reduced; the translation matrix is ​​used to move the tension joint to the correct relative position with the toe plate. According to the position of the toe board and the design requirements of the tension joint, the translation vector is determined to ensure that the connection between the tension joint and the toe board is reasonable. Multiple iterative adjustments are performed, and after each adjustment, the dot product of the tension joint direction vector and the toe board surface normal vector is calculated to determine whether the vertical relationship meets the requirements. If not, continue to adjust the matrix parameters until the predetermined accuracy is achieved.

[0053] Step 4: Create a block model of the anti-seepage panel and perform numbering. Figure 5 As shown, a block model of the anti-seepage panel is created according to the data input in step 1 to step 3, and each block model is numbered from left to right. Block numbering of the anti-seepage panel facilitates designers to identify and manage each block panel, and facilitates subsequent three-dimensional reinforcement block by block, thereby improving the coordination, accuracy and efficiency of the design work.

[0054] Step 5: Perform three-dimensional automatic reinforcement operation on the anti-seepage panel.

[0055] Reference Figure 6 As shown, the specific operation process includes the following steps:

[0056] Step 51: First, set the reinforcement type. The reinforcement types of anti-seepage panels include single-layer bidirectional and double-layer bidirectional reinforcement types. Different reinforcement types can be applied to different engineering requirements. For relatively low-height concrete panel rockfill dams, panels with relatively uniform stress distribution, and projects under non-extreme environmental conditions, single-layer bidirectional reinforcement can be selected; for high-panel rockfill dams, panels with complex stress distribution, important projects under harsh environmental conditions, and pumped-storage power stations with relatively complex operating conditions, anti-seepage panels mostly use double-layer bidirectional reinforcement. Designers can choose according to actual conditions.

[0057] Step 52: Select the reinforcement position. The reinforcement position of the anti-seepage panel includes the upper steel bars and the lower steel bars. When single-layer reinforcement is used, the steel bars should be placed in the middle of the panel section or in the position facing the water surface, and only the upper steel bars are arranged; when double-layer bidirectional reinforcement is used, the upper steel bars and the lower steel bars of the anti-seepage panel need to be arranged separately. Step 53: Set the reinforcement principle. This includes setting the axial and slope steel bar style, diameter, spacing and protective layer thickness of the anti-seepage panel.

[0058] Step 54: Generate three-dimensional reinforcement principles and perform parametric reinforcement. After the parametric three-dimensional model of the anti-seepage panel is generated, since the topological relationship of each panel is fixed, the structural surfaces such as the water-facing surface, the water-receiving surface (excavation surface), the upper plane, the lower bottom surface, the upstream side surface, the downstream side surface, etc. are coded, and each endpoint is also coded. Since the code number is fixed, the structural surfaces such as the water-facing surface, the water-receiving surface (excavation surface), the upper plane, the lower bottom surface, the upstream side surface, the downstream side surface, etc. of the structure where the steel bars need to be arranged can be searched according to these codes. For each steel bar object, such as the surface layer slope steel bar 1, the surface layer axial steel bar 2, the lower layer slope steel bar 4, the lower layer axial steel bar 5, etc., the reinforcement direction is fixed. Through the pre-set starting point code number in each steel bar, the corresponding structural point can be matched to determine the reinforcement range. Finally, the geometric relationship between the protective layer distance of the steel bar line and the anti-seepage panel contour line 3 structural surfaces is used, and after reading the parameters such as steel bar diameter, spacing, and protective layer from the database, the block panel that needs reinforcement is selected. Within the reinforcement range, a series of cross-sections are constructed perpendicular to the reinforcement direction. Each cross-section intersects with the reinforcement surface to obtain the intersection line. These intersection lines are the newly created steel bar lines, so that the anti-seepage panel shape is automatically matched according to the set reinforcement principle to arrange the axial and slope-oriented steel bars on different structural surfaces, such as Figure 7 This parametric reinforcement layout method improves the efficiency and accuracy of the design, while also ensuring the rationality and reliability of the reinforcement layout. Step 6: Batch generate the reinforcement drawings of the anti-seepage panels to complete the three-dimensional design process.

[0059] The specific operation process is as follows:

[0060] Step 61: Select a certain block anti-seepage panel and determine the cutting position. First, identify and manage each block panel according to the anti-seepage panel number, select the block panel number that needs reinforcement, set the horizontal section and vertical section in the middle of the three-dimensional structure of this block panel, and after calculating the intersection of each section and the three-dimensional structure, the contour line information at the cutting position can be obtained. Therefore, by selecting a specific block panel and determining the cutting position, the internal structure and reinforcement arrangement of the block panel can be displayed in more detail;

[0061] Step 62: Generate two-dimensional reinforcement drawings of each panel block one by one or in batches, such as Figure 8-Figure 11 As shown, it includes the plan view of the anti-seepage panel, the plan view of the surface reinforcement, the plan view of the bottom reinforcement and the typical cross-section views of each cutting position.

[0062] In this embodiment, the anti-seepage panel reinforcement diagram generated in step 6 is to arrange a layer of axial and slope-oriented reinforcement lines on the water-facing surface and the water-receiving surface, mainly surface slope reinforcement 1, surface axial reinforcement 2, lower slope reinforcement 4, and lower axial reinforcement 5; the three-dimensional information of the horizontal and vertical reinforcement lines on the structural surface of the anti-seepage panel is searched out through the water-facing surface and the water-receiving surface structural surfaces of the anti-seepage panel, and projection is performed to obtain the two-dimensional information of the contour lines and the reinforcement lines.

[0063] In this embodiment, step 6 is performed by setting a horizontal section and a vertical section in the middle of the three-dimensional structure of the anti-seepage panel. After each section and the three-dimensional structure are intersected, the contour line 3 information of the anti-seepage panel at the section position can be obtained. If the steel bar line is perpendicular to the section, the intersection point is the coordinate information of the point steel bar on the two-dimensional graph; if the steel bar line is perpendicular to the section, the first steel bar line located within the steel bar spacing distance is searched along the section direction, and after projecting it, it is the line steel bar of the section graph.

[0064] In this embodiment, the rebar drawing generated in step 6 includes point rebar and line rebar annotation units, annotation leaders, and attributes such as rebar diameter, number, and spacing. By putting the above information of each annotation unit together, a custom object is constructed. By operating the grip points on the annotation body geometry, the position of the rebar leader and annotation text can be easily adjusted to eliminate the overlap of annotation text.

[0065] In this embodiment, the reinforcement diagram generated in step 6 can be broken. By interactively specifying a rectangular area (break area) in the middle of the view, the contour lines and reinforcement lines in the rectangular area will be cleared, leaving only the left and right sides; the remaining contours, reinforcement lines, and reinforcement points on one side will be translated to the vicinity of the other side to form a broken view.
