Description

Technical Field

[0001] The invention belongs to the field of computer data processing and proposes a method and system for inputting tunnel overbreak and underbreak measurement design data. Background Art

[0002] The digitization of tunnel construction design primarily focuses on two key aspects: centerline design and lining mileage design. Centerline design determines the overall tunnel orientation based on factors such as the tunnel's geographic location, traffic demand, and engineering conditions. Lining mileage design, on the other hand, considers multiple factors, including structural load-bearing capacity and construction techniques, including the design outlines for each construction step and the corresponding mileage ranges. Traditional tunnel surveying and layout processes typically rely solely on centerline design to meet construction requirements. However, with the continuous advancement of information technology, particularly the widespread use of reflectorless total stations, the need for monitoring and measuring tunnel walls during construction to extract information on overbreak and underbreak is increasing. Conventional design documents typically treat the designed centerline and lining outlines and their corresponding mileages separately. Consequently, in actual construction, surveying often relies solely on the centerline. When cross-sectional analysis is required, manual extraction of relevant cross-sectional data is often required to calculate cross-sectional parameters and perform digital analysis.

[0003] Currently, traditional methods rely on manual extraction and calculation of cross-sectional data, a process that is inefficient and prone to errors. This, especially when working within strict project schedules, places an additional workload on grassroots construction. With the advancement of informatization in tunnel construction design, while digital tools such as BIM (Building Information Modeling)-based design systems have improved construction analysis efficiency to a certain extent, these tools still face compatibility issues with traditional construction processes and are not fully adaptable to the complex environment of tunnel construction. Furthermore, some solutions rely solely on proprietary algorithms for data integration, resulting in cumbersome data entry and processing processes and a high learning curve. Summary of the Invention

[0004] In order to overcome the defect of low analysis efficiency caused by the failure to combine road centerline and lining profile data in the above-mentioned prior art, the present invention proposes a method and system for inputting tunnel overbreak and underbreak measurement design data.

[0005] In order to achieve the above technical effects, the technical solutions of the present invention are as follows: A method for inputting tunnel overbreak and underbreak measurement design data comprises the following steps: Get the road centerline design data and add mileage index at the broken link; get the lining profile; Based on the road centerline design data, the lining profiles are organized in mileage order to obtain a unified tunnel design data set; performing data self-check on the unified tunnel design data set; If the data self-check passes, the unified tunnel design data set is exported as a standardized road file.

[0006] As a preferred solution, the road centerline design data is obtained by importing a standard road file, importing an intersection method straight-curve table, or manually entering the data.

[0007] As a preferred solution, the manual entry step includes entering the horizontal curve based on the intersection method or the element method.

[0008] As a preferred solution, the step of entering a horizontal curve using the intersection method includes: calculating straight line, circular curve and gentle curve elements based on the entered curve radius and gentle curve length and generating road centerline design data in sequence.

[0009] As a preferred solution, the lining profile is obtained by uploading a main point file, uploading a CAD file, entering data using the height difference and horizontal distance method, or entering data using the central angle method.

[0010] As a preferred solution, the data self-check includes checking the integrity of the data format, missing information and logical consistency.

[0011] As a preferred solution, the exported road file can be directly called by external software integrated with SDK.

[0012] The present invention further proposes a system for inputting tunnel overbreak and underbreak measurement and design data, which uses the method for inputting tunnel overbreak and underbreak measurement and design data, including: Data acquisition module, used to obtain road centerline design data and lining profile and its corresponding mileage data; The data association module organizes the lining profiles in mileage order based on the road centerline design data to obtain a unified tunnel design data set; a data self-checking module, configured to perform a self-check on the unified tunnel design data set; The data export module is used to export standardized road files when the data self-check passes.

[0013] The present invention also proposes an electronic device, comprising a memory, a processor, and a computer program stored in the memory and runnable on the processor. When the processor executes the computer program, it implements a method for entering tunnel over-excavation and under-excavation measurement design data as described in the present invention.

[0014] The present invention also provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the method for entering tunnel overbreak and underbreak measurement design data as described in the present invention is implemented.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By realizing the linkage between road centerline design and lining profile design, the present invention can provide a complete one-stop design data basis required for tunnel construction measurement, simplifying the traditional decentralized design method. It also provides normalized and standardized data support for subsequent measurement data analysis and over-break and under-break analysis, avoiding the tedious process of traditional manual association, thereby greatly reducing the need for human intervention.

[0019] The accompanying drawings are for illustrative purposes only and are not to be construed as limiting the present invention; It is understandable to those skilled in the art that some well-known descriptions may be omitted in the drawings.

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1 This embodiment proposes a method for measuring and designing tunnel over-break and under-break data. The implementation flow chart is as follows: Figure 1 shown.

[0022] This embodiment proposes a method for tunnel overbreak and underbreak measurement design data, comprising the following steps: S1. Obtain the road centerline design data and add mileage index at the broken link; obtain the lining profile; S2. Based on the road centerline design data, the lining profiles are organized in mileage order to obtain a unified tunnel design data set; S3. Performing data self-check on the unified tunnel design data set; S4. If the data self-check passes, export the unified tunnel design data set as a standardized road file.

[0023] This example establishes a unified design dataset by associating road centerline data with lining profile mileage indexes, achieving structured integration of tunnel construction survey data. A data self-checking mechanism ensures data integrity and logical consistency, ultimately outputting a standardized road file. This example significantly improves the standardization and reusability of design data, providing reliable data support for overbreak and underbreak analysis and reducing human error.

[0024] like Figure 2 FIG. 1 is a schematic diagram of a workflow of a method for tunnel over-break and under-break measurement and design data proposed in Example 1.

[0025] More specifically, the mileage before and after the break is saved at the broken link. For the road centerline design data and lining profile, it is necessary to distinguish whether the current survey mileage is within the broken link.

[0026] In an optional embodiment, obtaining the road centerline design data includes any one of importing a standard road file, importing an intersection method straight-curve table, or manually entering the data.

[0027] Specifically, importing standard road files provides a standardized way to import road files to create new engineering tasks. Importing intersection method straight curve tables provides standardized straight curve table import for generating road centerline designs.

[0028] In this embodiment, through a variety of lining profile acquisition methods, users can select an appropriate method according to specific needs, which improves the flexibility and applicability of data entry, thereby ensuring the integrity and accuracy of design data.

[0029] In an optional embodiment, the manual entry step includes entering the horizontal curve based on an intersection method or entering the horizontal curve based on an element method.

[0030] More specifically, the intersection method uses the center angle and radius of a curve as a basis, combined with the position of the road centerline, to determine the curve's geometry. The intersection method constructs intersection information by inputting intersection information (point name, north-east coordinates), curve radius, bend length (first bend, second bend), and calculation parameters (bend parameters, bend radius). The element method directly designs a road's alignment by constructing curve elements (such as line segments, circular curves, and bends). The element method constructs a road's horizontal curve by inputting line segments (length, azimuth), circular curves (length, azimuth, starting radius, direction), and bends (length, azimuth, starting radius, ending radius, and direction).

[0031] Furthermore, manual entry also includes vertical curve entry, which is achieved by entering the point name, mileage, elevation and radius to enter the vertical curve, calculate the slope ratio, and realize the data entry of the vertical curve.

[0032] In this embodiment, two horizontal curve entry methods that conform to engineering practices are provided to meet the needs of different scenarios. Among them, the intersection method is suitable for fast entry of simple lines, and the element method can handle complex line combinations.

[0033] In an optional embodiment, the step of entering the horizontal curve using the intersection method includes: calculating the straight line, circular curve and gentle curve elements based on the entered curve radius and gentle curve length and generating road centerline design data in sequence.

[0034] In this embodiment, by entering the basic parameters of the curve, a simple line shape can be quickly entered.

[0035] In an optional embodiment, obtaining the lining profile includes uploading a main point file, uploading a CAD file, entering data using a height difference and horizontal distance method, or entering data using a central angle method.

[0036] More specifically, the data in the uploaded main point file includes: circle center coordinates, tunnel center coordinates and radius.

[0037] In this embodiment, through multi-source heterogeneous data fusion technology, it supports both the import of BIM model data (master point file) and the analysis of traditional CAD drawings, and is compatible with commonly used on-site measurement methods (elevation difference horizontal distance / central angle method).

[0038] In an optional embodiment, the data self-check includes checking the integrity of the data format, missing information, and logical consistency.

[0039] In this embodiment, the self-checking mechanism can effectively ensure the quality of tunnel design data, reduce human errors, ensure high accuracy during data entry, and improve the efficiency and reliability of data processing.

[0040] In an optional embodiment, the exported road file can be directly called by external software integrated with SDK.

[0041] In this embodiment, the exported standardized road file can be seamlessly connected to the external system, reducing the user's operation complexity and integration workload, improving the flexibility and compatibility of the system, and further promoting the efficient sharing and application of tunnel design data.

[0044] It can be understood that the system of this embodiment corresponds to the method of the above-mentioned embodiment 1, and the options in the above-mentioned embodiment 1 are also applicable to this embodiment, so they will not be described again here.

[0045] Example 3 This embodiment proposes a computer device, including a memory and a processor, wherein the memory stores computer-readable instructions, wherein when the computer-readable instructions are executed by the processor, the processor executes the steps of the method for tunnel over-break and under-break measurement design data proposed in Example 1.

[0046] Example 4 This embodiment provides a storage medium having computer-readable instructions stored thereon, wherein the computer-readable instructions, when executed by a processor, implement the steps of the method for tunnel over-break and under-break measurement design data proposed in Embodiment 1.
