Description

Technical Field

[0001] The present invention belongs to the field of tunnel end reinforcement design, and in particular relates to a rail transit shield tunnel end reinforcement design method, system, equipment and medium. Background Art

[0002] In rail transit construction, the design of shield tunnel end reinforcement is an important part of ensuring tunnel structural stability and construction safety. However, designers in the rail transit industry currently still rely mainly on manual operations when performing this work, which is a cumbersome and inefficient process. Specifically, designers need to manually draw the longitudinal section end reinforcement range based on the geological longitudinal section conditions in the shield tunnel longitudinal section design plan file and mark the corresponding mileage information. After the design is completed, it is also necessary to manually measure the mileage range of the end reinforcement of each section of the longitudinal section, and based on this, manually draw the plane end reinforcement range and corresponding mileage markings one by one in the shield tunnel plane design plan file.

[0003] This process involves numerous manual operations, such as measuring lengths, editing polylines, adding text annotations, and pattern fills. This not only increases the designer's workload but also makes the entire process time-consuming. Furthermore, due to its heavy reliance on manual operations, human error is difficult to avoid, impacting design accuracy and construction feasibility. Therefore, improving the automation level of shield tunnel end reinforcement design, reducing repetitive work, and improving efficiency and accuracy has become a pressing issue within the industry.

[0052] S2. Open the rail transit shield tunnel longitudinal section design plan file and read the shield tunnel longitudinal section design plan data.

[0053] Specifically, the rail transit shield tunnel longitudinal section design scheme file is a dwg, dws, dwt, or dxf format file, and the shield tunnel longitudinal section design scheme data can be read based on the AutoCAD secondary development program described in step S1;

[0054] Specifically, the shield tunnel longitudinal section design scheme data includes line mileage data, line longitudinal section slope data, line longitudinal section vertical curve data, station and shield tunnel interface data, shield tunnel cross-section dimensions, section name and section start and end mileage data;

[0055] Specifically, the rail transit shield tunnel longitudinal section design plan file includes a shield tunnel geological longitudinal section.

[0056] S3. Based on the longitudinal section design scheme data of the shield tunnel, the station and shield tunnel interface data are calculated. According to the station and shield tunnel interface data, the station and shield tunnel interface to be reinforced that needs to be designed for end reinforcement is obtained, and the mileage of the station and shield tunnel interface to be reinforced is obtained.

[0057] Specifically, according to the station and shield tunnel interface data described in step S2, the station and shield tunnel interface to be reinforced that need to be designed for end reinforcement is selected, and the mileage of the station and shield tunnel interface to be reinforced is obtained.

[0058] S4. According to the mileage of the interface between the station to be reinforced and the shield tunnel, set the data of the area to be reinforced at the end of the longitudinal section of the shield tunnel within the interface between the station to be reinforced and the shield tunnel.

[0059] Specifically, the scope of the shield tunnel longitudinal section end to be reinforced includes the end reinforcement mileage range and the end reinforcement elevation range;

[0060] Specifically, the end reinforcement mileage range is determined by inputting the length of the end reinforcement range along the line centerline based on the mileage of the interface between the station and the shield tunnel in step S3.

[0072] Specifically, the upper and lower boundaries of the pattern filling range are determined according to the polyline contours of the upper and lower areas of the shield tunnel longitudinal section end reinforcement in step S4;

[0073] Specifically, the pattern and proportion of the pattern filling of the longitudinal section end reinforcement range are preset in the AutoCAD secondary development program in step S1.

[0074] S5.2. Automatically draw the mileage mark of the longitudinal section to be reinforced at the end in the shield tunnel longitudinal section design plan file.

[0075] Specifically, the mileage marking of the longitudinal section of the end to be reinforced includes a marking leader and corresponding mileage text, wherein the insertion position of the marking leader is the left boundary and the right boundary of the pattern filling range in S5.1, and the mileage text content is determined according to the starting mileage and the ending mileage of the end reinforcement in step S4.

[0076] S6. Open the rail transit shield tunnel plane design plan file, read the shield tunnel plane design plan data and the data of the area to be reinforced at the end of the longitudinal section of the shield tunnel.

[0079] S7. Calculate and set the width parameter of the area to be reinforced at the end of the shield tunnel plane according to the shield tunnel plane design plan data and the data of the area to be reinforced at the end of the shield tunnel longitudinal section.

[0080] Specifically, the width parameter is calculated using the following formula:

[0081] Width parameter = 2 × single-side offset + line spacing;

[0082] Among them, the unilateral offset is a preset distance expanded outward to one side along the center line of the shield tunnel based on the data of the area to be reinforced at the end of the longitudinal section of the shield tunnel, and the line spacing is automatically parsed from the plan design data of the shield tunnel.

[0084] Step S8 specifically includes the following steps:

[0085] S8.1. Automatically draw the pattern filling of the area to be reinforced at the plane end in the shield tunnel plane design plan file.

[0086] Specifically, the pattern filling of the plane end area to be reinforced is arranged along the center line of the shield tunnel plane, and the pattern filling range can be divided into a pattern filling mileage range and a pattern filling plane range width, wherein the pattern filling mileage range is determined according to the end reinforcement mileage data in the longitudinal section end area to be reinforced data in step S4, and the pattern filling plane range width is the width of the shield tunnel plane end area to be reinforced in step S7;

[0090] Figure 2 and Figure 3 This is a schematic diagram of the shield tunnel longitudinal section and planar end reinforcement design results of the present invention.

[0091] This invention uses AutoCAD secondary development technology to achieve automated design of shield tunnel end reinforcement. Specifically, a dedicated program module is developed in the C++ or C# programming language. When the program is run, it first automatically reads design files in DWG / DWS / DWT / DXF formats and analyzes key data such as route mileage, slope, and geological profile. It then intelligently calculates the reinforcement boundaries in both longitudinal and planar dimensions based on the input reinforcement parameters. Finally, it automatically generates standard design elements in the AutoCAD environment, including polyline boundaries, pattern fill areas, and mileage annotation text, and outputs the design results.
