Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail transit line design, and in particular to a line and slope design method and system for a rail transit section tunnel. BACKGROUND

[0002] With the acceleration of urbanization in China, urban rail transit has been widely used as an important means to improve traffic conditions and promote urban development. In urban rail transit construction, underground section tunnels are the key part connecting various stations, and their design and construction quality directly affect the operation safety and efficiency of the entire system. Due to the complexity of urban underground space and the requirements of environmental protection, rail transit section tunnels are usually constructed by underground laying methods such as open-cut method, underground excavation method or shield method. However, these construction methods inevitably introduce measurement errors, construction errors, structural deformations and human operation errors, etc., resulting in certain deviations between the actual built tunnel and the design. Therefore, after the tunnel is completed, line plane adjustment and fitting and longitudinal section slope adjustment and fitting must be carried out to ensure the safety and comfort of train operation and provide accurate basis for subsequent track laying, catenary installation and installation of other equipment.

[0003] The traditional line and slope design of rail transit section tunnels mainly relies on the table method, that is, the construction unit measures the completed tunnel, calculates the information of the target tunnel section such as mileage, design coordinates and elevation at certain mileage intervals, and records these data in a table. After receiving the table, the design unit calculates the plane deviation of each section using self-programmed formulas, evaluates the deviation distribution of different line types, adjusts the line plane intersection position and curve parameters, etc., to eliminate the deviation between the design data and the measured data as much as possible. After completing the line adjustment, further slope design is carried out, based on the original longitudinal section design, to edit formulas to calculate the design elevation and clearance of the target mileage section, compare and analyze with the measured data, adjust the parameters such as slope length, elevation and slope, etc., until the section clearance meets the requirements of the running limit.

[0004] Although the traditional line adjustment and slope adjustment design method is relatively mature under the existing tool conditions, it still has some shortcomings. First, due to the existence of superelevation settings, the centerline of the tunnel is not the centerline of the line, and manual conversion is required during the coordinate calculation process. This process is time-consuming and prone to errors. Secondly, the traditional method requires designers to frequently switch between drawings and tables during the repeated adjustment and verification of line types and slopes. It cannot intuitively display deviations and make design adjustments, which increases workload and time costs. Finally, this method lacks effective plane line type fitting and slope fitting tools, and requires a high level of experience from designers. Only designers with rich experience can correctly judge the adjustment direction of the line type and the corresponding parameters. This undoubtedly raises the technical threshold for line adjustment and slope adjustment design. Summary of the Invention

[0040] The present invention provides a line adjustment and slope adjustment design method and system for rail transit section tunnels. The method and system can enable designers to quickly become familiar with the principles and processes of line adjustment and slope adjustment, realize flexible switching display between the line centerline and the tunnel centerline and seamless automatic conversion of spatial coordinates, and can display measured section data on the horizontal and vertical drawings of the designed line, which is more intuitive and vivid, and is convenient for designers to evaluate and judge deviation adjustments.

They can use the line adjustment and slope adjustment fitting tools to perform one-click fitting on the measured tunnel section data, and can also use the horizontal and vertical design tools to make adjustments, so that the overall system function integrates automation and flexibility.

[0041] Example 1:

[0042] like Figure 1 As shown, an embodiment of the present invention provides a line adjustment and slope adjustment design method for a rail transit section tunnel, comprising:

[0043] S100, converting the line centerline custom entity object into a tunnel centerline custom entity object;

[0044] The centerline of a line usually refers to the centerline of the track. Its line type consists of straight lines, gentle curves, and circular curves. Due to the need for driving comfort, the track needs to be set with superelevation on circular curves, but this is restricted by the vehicle clearance in the tunnel.

[0045] like Figure 2 As shown, the track centerline and tunnel centerline will offset depending on the superelevation setting, with the offset proportional to the superelevation. That is, the offset value is fixed on circular curves, zero on straight lines, and gradually changes from zero to a fixed value along the length of transition curves. To calculate the coordinates of any mileage point on the tunnel centerline, the coordinates of that mileage point on the line centerline must first be calculated, and then the corresponding offset value is shifted inward toward the curve. Therefore, the data and interface of the tunnel centerline object are essentially the same as those of the line centerline, with the addition of data information on the offset values ​​of each line curve and an interface for querying the offset value of any mileage point.

[0046] The tunnel centerline custom entity object in this embodiment is derived based on the line centerline custom entity object, and the line centerline custom entity object is derived based on the entity base class object of the AutoCAD platform. Figure 3As shown, the tunnel centerline custom entity object inherits all data and method interfaces of the route centerline custom entity object. In terms of data, the tunnel centerline custom entity object contains not only the intersection information, field and office break information, and plotting style information of each element of the route custom entity object, but also the offset value information of all planar curves. In terms of method interfaces, the tunnel centerline custom entity object contains not only the intersection editing interface, break editing interface, style editing interface, mileage positioning interface, and geometric projection interface of the route custom entity object, but also the offset value editing and querying interface, which can not only edit the fixed offset value of each circular curve on the tunnel centerline, but also query the offset value of any mileage point on the tunnel centerline. In addition, the mileage positioning interface and geometric projection interface of the tunnel centerline custom entity object are restructured to allow mileage positioning and projection point querying on the tunnel centerline.

[0047] The present embodiment provides a tunnel centerline design tool set for the tunnel centerline custom entity object, including a file I / O tool set, offset editing tool set, centerline conversion tool set, and line fitting tool set. The file I / O tool set supports hard disk access operation of the offset value information of the tunnel centerline custom entity object in the PYZ custom format file. The offset editing tool supports customizing and modifying the fixed offset value of any circular curve on the tunnel centerline by the designer. The centerline conversion tool supports mutual conversion between the route centerline custom entity object and the tunnel centerline custom entity object by the designer. The line fitting tool supports line fitting of the tunnel centerline custom entity object according to the measured section data. Since the tunnel centerline custom entity object inherits the route centerline custom entity object, the route centerline design tool set can also perform editing operation on the tunnel centerline custom entity object.

[0048] S200, edit and extract tunnel measured data and import the tunnel centerline custom entity object to form a scatter point adjustment annotation custom entity object;

[0049] The present embodiment extracts and edits the tunnel measured data to form a PTS custom text format file, and imports and loads the file to the designed tunnel centerline custom entity object to form a scatter point adjustment annotation custom entity object. The subway tunnel section is generally formed by splicing circular tunnel segments, and the circular tunnel will present an elliptical section form under the double action of soil pressure and groundwater buoyancy after construction, and gradually stabilize. The actual measurement of the tunnel section after adjustment of the line and slope is generally performed after the section form stabilizes.

[0050] As Figure 4As shown, the long axis of the elliptical tunnel section is horizontal, and the short axis is vertical. The length of the short axis is generally less than the design value of the tunnel diameter. In combination with the design experience of adjusting the line and slope, four data need to be extracted for a single measured tunnel section, which are: the geodetic coordinates (X, Y) corresponding to the center point of the section, the top elevation Z1 of the tunnel section, and the bottom elevation Z2 of the tunnel section. The data of a single section is arranged as a row, and the data of all sections are arranged in the order of mileage to form a PTS custom text format file. Then, the measured data editing tool of the scatter point adjustment and annotation design tool set is used to generate a scatter point adjustment and annotation custom entity object.

[0051] In order to more intuitively view the positional relationship between the design tunnel center line and the plane deviation between each measured tunnel section on the CAD drawing, the embodiment faces the measured tunnel section data and the deviation annotation, and defines a scatter point adjustment and annotation custom entity class, as shown in the formula (1). Figure 5 As shown, the scatter point adjustment and annotation custom entity class is derived from the entity base class object of the AutoCAD platform, and contains three types of data, i.e., tunnel measured section data, tunnel design section data, and plane deviation parameter style, and editing interfaces of the three types of data, i.e., measured data editing interface, design data editing interface, and style editing interface. The tunnel measured section data is a data linked list of the measured section, and each unit records the center coordinates and the top and bottom elevations of the measured section. The tunnel design section data is a data linked list formed by the design values corresponding to each measured section, and each unit records the design coordinates and the track surface elevation corresponding to the same measured section. The plane deviation parameter style records the maximum allowed deviation between the measured and the design, and the corresponding warning annotation color, font and other information.

[0052] The embodiment provides a scatter point adjustment and annotation design tool set. The measured data editing tool set supports a designer to specify a design tunnel center line object, generate a scatter point adjustment and annotation object, and initialize the object by importing a PTS custom text format file. The design data editing tool set allows the designer to update and modify the tunnel design section data in the scatter point adjustment and annotation object by specifying the tunnel center line object. The parameter style modification tool set allows the designer to modify the overrun parameters and the annotation style information of the scatter point adjustment and annotation object.

[0053] S300, set the plane deviation parameter style of the scatter point adjustment and annotation custom entity object, calculate and display the plane deviation between the design tunnel center line and each measured tunnel section based on the tunnel measured data;

[0054] After the initialization of the scatter adjustment mark custom entity object, the designer sets the plane deviation parameter style of the object, mainly sets the maximum value of the plane deviation allowed, and the corresponding over-limit warning mark color, font size and other information. After setting, according to the tunnel measured section data of the object, the design tunnel centerline object is specified, the geometric projection interface of the tunnel centerline custom entity object is called, the projection of the measured section center point on the design tunnel centerline is queried section by section, the projection point is recorded in the tunnel design section data of the scatter adjustment mark object according to the mileage order, and the distance and deviation direction of the measured section are calculated. Determine whether the deviation distance is over-limit, determine the drawing color according to the over-limit situation, and mark the measured section mileage and the corresponding deviation distance according to the deviation direction of the plane deviation.

[0055] S400, according to the plane deviation between the design tunnel centerline and each measured tunnel section, use the automatic fitting tool to complete the tunnel design centerline plane fitting;

[0056] The line type automatic fitting tool of the tunnel centerline mainly has a straight line fitting tool and a curve fitting tool. After using the straight line automatic fitting tool, the designer first selects the straight line segment of the tunnel centerline object to be fitted, and then selects the reference scatter adjustment mark object. The tool prompts the designer whether the straight line needs to be rotated. If it needs to be rotated, the system will first adjust the slope, that is, the average slope is calculated by using the center points of all measured sections in the scatter adjustment mark object, and the slope of the target straight line is adjusted to the average slope. Then adjust the translation. If the straight line does not need to be rotated, it will directly enter the translation adjustment. During the translation adjustment, the average value and direction of the projection deviation distance between each measured section and the adjusted straight line segment are calculated, and the straight line segment is adjusted according to the calculation result. The curve automatic fitting tool mainly uses the concentric circle principle of the circular curve. After using the tool, first select the curve segment of the tunnel centerline object to be fitted, and then select the reference scatter adjustment mark object. The tool calculates the average value and direction of the projection deviation distance between each measured section and the circular curve segment, and adjusts the circular curve segment according to the calculation result. The adjustment of the circular curve is calculated by the concentric circle method. The radius of the circular curve before adjustment is R1, the easement curve is LS1, and the average deviation is D. When the deviation is inside the circular curve, the direction coefficient FX is-1, and when the deviation is outside the circular curve, the direction coefficient FX is 1. Then the radius of the adjusted circular curve can be calculated as R2=R1+FX*D, and the easement curve is LS2=√[LS12+FX*D*(R2*24)].

[0057] In this step, in addition to the automatic fitting tool in the tunnel centerline design tool set, the intersection editing tool, the straight line editing tool and the curve editing tool in the line centerline design tool set can also be used to manually adjust the tunnel centerline object.

[0058] S500, based on the scatter adjustment mark custom entity object and the tunnel centerline design object after plane fitting, generate the longitudinal section slope adjustment custom entity object;

[0059] In order to facilitate the use of slope adjustment tool, and in line with the design of the slope section design habit, the slope adjustment custom entity object of the embodiment is derived based on the slope custom entity object, as shown in Figure 6 The line slope custom entity object is derived based on the entity base class object of the AutoCAD platform, and is mainly used for longitudinal section slope section design. The slope adjustment custom entity object inherits all the data and method interfaces of the slope custom entity object. In terms of data, in addition to the plane intersection information, the mileage break information, the slope change data information and the slope drawing style of the slope custom entity object, the slope adjustment custom entity object also contains the tunnel measured section data, the longitudinal section clearance parameter style, the tunnel measured section data is a data linked list formed by the design values corresponding to each measured section, each unit records the design coordinates and track surface elevation corresponding to the same measured mileage section, and the longitudinal section clearance parameter style records the allowed maximum deviation of the track surface upper clearance and lower clearance, as well as the corresponding warning label color, font and other information. In terms of method interface, in addition to the plane information editing interface, the grid attribute interface, the slope change point editing interface, the elevation query interface, the longitudinal section column editing interface and the longitudinal section label interface of the slope custom entity object, the slope adjustment custom entity object also contains the clearance editing query interface and the clearance style editing interface. The clearance editing query interface can not only edit the section measured data, but also query the clearance value between the design elevation of any mileage point track surface and the measured tunnel top and bottom elevation. The clearance style editing interface can access and edit the longitudinal section clearance parameter style data.

[0060] The embodiment provides a slope adjustment design tool set around the slope adjustment custom entity object. It contains slope adjustment initialization tool set, slope section fitting tool set and clearance style tool set. In this step, the slope adjustment initialization tool set and the clearance style tool set are mainly used to generate and set the longitudinal section slope adjustment custom entity object.

[0061] The slope adjustment initialization tool set can support the designer to select the tunnel centerline object, extract the plane intersection and mileage break information, select the scatter adjustment mark object, extract the measured section data, import the slope design data in SQX custom file format, and pop up the clearance style editing dialog box to obtain the allowed minimum upper and lower clearance values, warning color, font and other label styles. According to the above data, the slope adjustment custom entity object is initialized and generated.

[0062] The clearance style tool set allows the designer to modify the minimum allowed upper clearance, the minimum allowed lower clearance, the compliance color and the out-of-limit color of the slope adjustment custom entity object, and the identification content whether to contain mileage, font size and other information.

[0063] S600, obtaining the upper and lower clearance conditions of the measured section based on the longitudinal gradient self-defined entity object, and using the slope section fitting tool set to complete the automatic fitting of the longitudinal slope section gradient.

[0064] According to the tunnel measured section data of the object, the elevation query interface of the gradient self-defined entity object is called, the projection mileage and design elevation of the measured section are queried section by section, and the track surface upper clearance between the design elevation and the measured top elevation of the measured section and the track surface lower clearance between the measured bottom elevation of the measured section are calculated. The labeling and drawing color is determined according to the out-of-limit condition. The upper clearance is labeled and drawn above the gradient line, and the lower clearance is labeled and drawn below the gradient line. After the generation of the gradient self-defined entity object, the system will automatically generate the longitudinal section column and grid. Then, according to the upper and lower clearance conditions of the measured section, the slope section fitting tool set in the gradient design tool set is used to complete the automatic fitting of the longitudinal slope section gradient, including: selecting the slope section that needs to be fitted by the gradient self-defined entity object, prompting the designer whether the slope section needs to be adjusted, if it needs, first adjust the slope, that is, calculate the average slope by using the center point elevation of all measured sections, adjust the slope of the target slope section to the average slope, and then adjust the lifting and falling of the slope section. If the slope section does not need to be adjusted, it will directly enter the lifting and falling adjustment of the slope section. When lifting and falling adjustment, the upper and lower clearances of the target slope section will be sorted respectively, and the sum of the sorted upper and lower clearances will be added in order to obtain the section with the maximum sum of upper and lower clearances and not exceeding the limit. With this section as the reference, the relationship between the upper and lower measured clearances and the clearance limit value is judged, and then the lifting and falling amount of the slope section is determined, and the slope of the slope section is adjusted.

[0065] In addition to using the slope section fitting tool in the gradient design tool set, the line longitudinal design tool set can also be used to manually adjust the gradient self-defined entity object.
