Description

Technical Field

[0001] The present invention relates to the field of building technology, and in particular to an integrated calculation method and device for airport earthwork in a fusion business scenario. Background Art

[0002] All parts of the airport are built on the earth's surface, which is undulating. Obviously, the original ground cannot be used directly by aircraft and needs to be transformed to be relatively flat to meet the requirements of aircraft use. This requires terrain design for the airport, which mainly includes determining the slope of the entire field and calculating the earthwork volume. In the prior art, in the preliminary design and construction drawing design stage, due to the high accuracy requirements for earthwork calculation, the average working elevation method is usually used for calculation. Its workflow is as follows: Figure 1 As shown, it includes the steps of site plane planning, determining the site design slope, site grid planning, determining the grid intersection data and site earthwork calculation.

[0003] The current earthwork calculation has the following shortcomings:

[0004] 1. The steps cannot be linked. This includes the inability to link the site design slope with the grid planning, and the inability to link the site design slope with the grid surface design elevation data. Among them, since the airport surface is composed of many faces, there are many horizontal slopes and vertical slopes. In the existing technology, the earthwork grid planning first distinguishes the faces with the same slope. Therefore, if the site design slope changes, that is, the slope change position changes, the grid must be re-planned. And the grid point data of the flight site, such as Figure 2 As shown, there is a problem that the site design slope and the grid surface design elevation data cannot be linked, which results in the need to manually reprocess other data after a certain data changes.

[0005] 2. The automation of the earthwork grid planning in the site is insufficient. The earthwork grid planning is to distinguish the surfaces with the same slope, and distinguish the road surface area and the soil area, and then further subdivide them according to the same size on this basis. For this work, there are several current methods: one is to complete it manually, but it takes a long time; the second is to use the current auxiliary software, but it can only grid the surfaces with the same slope, and it is necessary to manually determine the division surface first, resulting in a site area. Many surfaces need to be divided, which is time-consuming and the earthwork calculation also needs to be calculated by partition; the third is to perform grid division in advance during the terrain survey, which leads to limited planning. Once the planning position is changed, the data must be re-surveyed.

[0006] 3. The surface design elevation must be set by area. Figure 3 This is a partial schematic diagram of the slope control of an airport. Figure 3It can be seen that the airport surface is composed of multiple faces, and there are transverse and longitudinal slopes. And each face can be divided into several squares of about 20m×20m. After determining the slopes of the four sides of a face and the elevation of the control point, the elevation of each small square point within the face can be determined, that is, the design elevation. The current earthwork calculation software can only calculate faces with the same transverse and longitudinal slopes, resulting in an airport having to be divided into multiple faces for calculation, which is cumbersome. Summary of the invention

[0007] In view of this, the purpose of the present invention is to provide an integrated calculation method and device for airport earthwork in a fusion business scenario, so as to overcome the problem of cumbersome and complex earthwork calculation and low efficiency during the current airport construction.

[0043] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0044] Figure 4 This is a flowchart of an integrated calculation method for airport earthwork in a fusion business scenario provided by an embodiment of the present invention. Figure 4 , this embodiment may include the following steps:

[0045] S101. Establish a coordinate system based on a measurement map, and determine the coordinates of each measurement point in the measurement map to obtain coordinate data.

[0046] Specifically, the survey map of the area where the airport is to be built can be rotated a certain angle in the preset software to the horizontal direction of the runway, the OPH (P is the horizontal coordinate, H is the vertical coordinate) coordinate system can be established, and the PH coordinates of each measuring point can be determined to obtain the coordinate data. It should be noted that the establishment of this coordinate system is mainly to provide position coordinates for subsequent plane parameterization, slope design and database creation, and these steps are all carried out on the basis of this step.

[0047] S102. Based on the survey map and coordinate data, plan the airport plane planning parts, and assign attributes to each airport plane planning part.

[0048] This step is to carry out plane parametric planning, which mainly assigns attributes to the airport plane planning parts so that the subsequent earthwork grid can distinguish between the pavement area and the soil area.

[0049] Specifically, it can include assigning hardening function area attributes, construction property attributes and filling material attributes for the pavement area; among them, hardening function area attributes include runway, U-turn pad, transition section / end hardening, end contact road, middle contact road, rapid exit taxiway, taxiway and apron; construction property attributes include covering, reconstruction and new construction; filling material attributes include cement concrete and asphalt concrete. The soil surface (i.e. soil area) is not divided into zones.

[0050] S103. Create longitudinal and transverse section diagrams of the airport area based on the planning results, and determine the design slope and design elevation of each airport plane planning part.

[0051] This step is the design of the longitudinal and transverse slopes of the site. Specifically, multiple horizontal and longitudinal section lines can be determined according to the above planning results, and multiple longitudinal section diagrams can be created to form longitudinal and transverse section diagrams of the site, and the longitudinal and transverse section diagrams of the site can be used to design the slope and elevation of each airport plan area, that is, to determine the design slope and design elevation of each airport plan area (it should be noted that the design slope and design elevation in this application are the slope and elevation designed according to building requirements, which are different from the data of natural ground).

[0052] S104. Automatically create a grid.

[0053] Specifically, the boundaries of the earthwork grid are determined based on the edge lines of the outermost airport plan area and the preset distance value; the edge lines of each airport plan area are used as the first vertical and horizontal lines of the earthwork grid; the slope change positions in the vertical and horizontal profiles of the site are used as the necessary points to generate the second vertical and horizontal lines of the earthwork grid; and the third vertical and horizontal lines of the earthwork grid are generated by preset refined standard specifications to create the earthwork grid.

[0054] S105. Improve the design elevation data based on the earthwork grid and generate a surface design elevation database.

[0055] It should be noted that the design slope and design elevation of each airport plane planning part have been designed and determined in the above step S103, but the data designed in this part is not complete relative to the data used to calculate the earthwork in the end. For example, the design elevation of each airport plane planning part in step S103 cannot cover the design elevation of all intersections in the subsequently generated earthwork grid, that is, there are still some intersections in the earthwork grid that do not have a design elevation. Therefore, in this step, the design elevation data is improved on the basis of the design data in step S103, that is, the design elevation of the intersections in the earthwork grid other than the positions where the design elevation has been determined in step S103 is determined.

[0056] S106. Perform earthwork calculation based on the surface formed by the design elevation in the surface design elevation database and the surface formed by the actual natural ground in the site.

[0057] Specifically, earthwork calculations can be performed based on the surface formed by the design elevation in the surface design elevation database and the natural surface formed by the natural ground measurement data. For example, the two surfaces can be superimposed through a preset software program, and the filling and excavation form can be determined based on the comparison between the design elevation of the intersection in the earthwork grid and the corresponding natural ground elevation to perform earthwork calculations.

[0058] The integrated calculation method for airport earthwork in a fusion business scenario provided by the present application, on the one hand, can realize the identification of different structural areas by assigning attributes to the airport plane planning parts, so as to achieve the automatic creation of earthwork grids that distinguish different structures; on the other hand, by identifying the slope change positions in the longitudinal and transverse profiles of the site as the basis for creating the earthwork grid, it is possible to automatically create earthwork grids on the same slope surface; and by associating the elevation data of the intersection of the longitudinal sections, it is possible to realize the automatic association of the longitudinal sections in the site, so that when the design elevation of a certain longitudinal section changes, the one associated with it can be automatically adjusted; and the surface design elevation of the site controlled by one point can be automatically created through the longitudinal and transverse profiles of the site, which can greatly improve the efficiency of airport design, especially earthwork calculation.

[0059] Figure 5 : is a schematic diagram of the distribution of the longitudinal and transverse profiles of the midfield area in the integrated calculation method of the airport earthwork in the fusion business scenario provided by the embodiment of the present invention, such as Figure 5 As shown ( Figure 5 The black solid lines with the positions of the apron, taxiway, flat area and runway are the edges of the airport plan. In this embodiment of the application, the longitudinal and transverse longitudinal lines (such as Figure 5 The dotted lines in the figure show the longitudinal sections 1-11), wherein each longitudinal section line corresponds to a longitudinal section diagram, and the longitudinal and transverse longitudinal section diagrams of the field mentioned above are composed of all the longitudinal section diagrams.

[0060] As introduced in the above embodiments of the present application, the information of the longitudinal and transverse profiles of the above-mentioned site can be used as the basis for creating an earthwork grid. For example, the slope change position (P, H) in each longitudinal profile can be used as the basis for creating a soil grid, so as to realize the creation of an earthwork grid that distinguishes surfaces with the same slope.

[0061] In addition, in the present application, the elevation data (mainly the design elevation) of each longitudinal section can be associated through the intersection point, so that when the elevation in a longitudinal section changes, the one associated with it can be automatically adjusted. The intersection point can be determined by its own information or the intersection point of the longitudinal section line.

[0062] Figure 6 is a schematic diagram of a part of the earthwork grid in the integrated calculation method of airport earthwork in the fusion business scenario provided by the embodiment of the present invention, such as Figure 6 As shown, in the embodiment of the present application, based on the above information data, it is possible to automatically create an earthwork grid that distinguishes the pavement area, the soil area, and the entire field of the same slope surface, specifically including:

[0063] The boundary lines of each airport plan area after attribute assignment are defined as the first vertical and horizontal lines in the earthwork grid (also referred to as boundary line layout lines); the slope change position in the vertical and horizontal longitudinal section diagram of the site is defined as the necessary position of the vertical and horizontal lines, and the second vertical and horizontal lines in the earthwork grid (also referred to as slope change layout lines, where it should be noted that when a slope change position has been passed by the first vertical and horizontal lines, there is no need to set additional lines, or when a horizontal line in the first vertical and horizontal lines passes through a slope change position, in this step, only the vertical line passing through the slope position can be added; and the boundary line of the airport plan area (the outermost airport plan area) is used as a reference to expand a certain distance, that is, a preset distance value, as the layout boundary, that is, the boundary line of the earthwork grid; and the third vertical and horizontal lines of the earthwork grid are generated by preset refined standard specifications, such as subdividing with a refined standard specification of 20m×20m (to avoid Figure 6 Too complex to distinguish, so this part is Figure 6 (Not fully drawn in the figure, but can be understood based on this part of the text) The grid generated by the above-mentioned arrangement of boundaries, the first vertical and horizontal lines, and the second vertical and horizontal lines eventually forms an earthwork grid.

[0064] On this basis, the global control points are selected, and then based on the global control points and the determined design slope and design elevation, the design elevations of all intersections in the earthwork grid are determined to generate a surface design elevation database.

[0065] For example, the global control point can be the midpoint of one end of the runway. Correspondingly, the generated surface design elevation database may include:

[0066] S201. Along the direction parallel to the runway, based on the design elevations of all control points in the field, determine the design elevations of all intersections in the earthwork grid at the centerline of the runway.

[0067] Specifically, the design elevation of all intersection points in the earthwork grid at the centerline of the runway can be automatically calculated along the direction parallel to the runway through a preset software program. The calculation formula is as follows:

[0068]

[0069] Where: Z p is the design elevation of the intersection point to be calculated in this step; Z p-1 is the design elevation of the previous intersection point of the current intersection point to be calculated in this step; i is the slope between the two intersection points; L p To calculate the distance, that is, the distance between the two intersection points, that is, the difference in the P values ​​of the two intersection points.

[0070] S202, and determining the design elevations of the remaining intersections in the earthwork grid based on the design elevations of the intersections in the earthwork grid at the centerline of the runway and the determined design slopes and design elevations.

[0071] Specifically, for the design elevation of other intersections in the earthwork grid, the transverse slope (such as Figure 6 The slope corresponding to the center longitudinal line 6-11 is calculated by the design elevation of the intersection with the runway centerline. The calculation formula is as follows:

[0072]

[0073] Where: Z H is the design elevation of the intersection point currently to be calculated in this step; The design elevation of the upper and lower intersection points of the current intersection to be calculated (the upper and lower intersection points are based on Figure 6 i the slope between the corresponding intersection points; L H To calculate the distance, the difference in H values ​​corresponding to the two intersection points.

[0074] It should be noted that, because the longitudinal and transverse sections of the site are created based on the planning results, and the design slope and design elevation of each part of the airport plan are determined, a large amount of data on the design slope and design elevation are determined (and the design position can be specified, etc.), so when calculating the design elevations of other intersections in the earthwork grid in this step, the design elevations of the upper and lower intersections of the current intersection to be calculated can always be determined.

[0075] In this way, the surface design elevation of the intersection of the earthwork grid, that is, the design elevation, can be achieved through the longitudinal and transverse slopes and a single control point. On this basis, the design elevation is extracted point by point in the direction parallel to the runway to generate a surface design elevation database, and then the earthwork calculation is performed based on the surface formed by the design elevation in the surface design elevation database and the surface formed by the actual natural ground in the site.

[0076] The integrated calculation method for airport earthwork in the integrated business scenario provided by the present application can automatically create an earthwork grid that distinguishes the pavement area, the soil area and the entire field with the same slope surface, and realize the mutual association between the plane planning, the field slope and the earthwork grid, so that the earthwork grid can be automatically arranged according to the design facility layout, and the automatic association between the design facility layout and the grid can be realized; moreover, the elevation data of each longitudinal section diagram is associated through the intersection point, so that after the elevation of a longitudinal section diagram is changed, the associated ones can be automatically adjusted; and the longitudinal and transverse longitudinal sections of the field area are automatically created by a The surface design elevation of the site controlled by the point can realize the automatic association between the surface design elevation and the site slope design; and by assigning attributes to the airport plane planning parts, it can realize the identification of different structural areas, and can automatically calculate the earthwork calculations of structural types such as pavement cover area, pavement reconstruction area, pavement new construction area and soil area at the same time; and in the entire terrain design, engineering personnel can focus their main energy on the design of the longitudinal and transverse slopes of the site, while the earthwork grid layout and earthwork calculations can be automatically completed by the software program, saving manpower, shortening working time and improving work efficiency.
