[0002] With the development of the transportation industry, the implementation of linear projects such as high-speed railways, intercity railways, urban railways, and various rail transit systems has brought convenience to transportation, but its impact on environmental vibration along the route has also become increasingly prominent. To mitigate the environmental vibration impact of such projects, the current main approach is to evaluate them through environmental impact assessment reports and implement the proposed vibration reduction measures. The preparation of environmental impact assessment report prediction calculation sheets (Excel calculation sheets) has always suffered from significant manual intervention and low work efficiency. During the preparation process, adjustments to the project often lead to repetitive work, resulting in errors and omissions. Furthermore, the environmental vibration mapping work for environmental impact assessment reports is extensive, and the alignment of linear projects such as railways is prone to change at various stages, often requiring rework.

[0058] To address at least one of the technical problems existing in the aforementioned related technologies, this invention provides a method for evaluating the environmental vibration impact of rail transit projects. Figure 1 This is a flowchart illustrating a method for evaluating the environmental vibration impact of a rail transit project, provided as an embodiment of the present invention.

[0059] As an embodiment of the present invention, such as Figure 1 As shown, the environmental vibration impact assessment method for the rail transit project includes:

[0060] Step S100: Construct a basic database based on project information and source strength information;

[0065] It should be noted that the execution subject in this embodiment can be an electronic device, which can be a computer device with data processing function, or other devices that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment, a computer device is used as an example for explanation.

[0066] Understandably, to address the current problems of long on-site investigation cycles, heavy workload in later analysis stages, excessive reliance on manual labor, low efficiency, high error rates, and inefficient adjustments during linear engineering design and environmental impact analysis, the environmental vibration impact assessment method for rail transit projects provided in this embodiment is generally applicable to environmental vibration impact assessments of linear engineering projects such as high-speed railways, intercity railways, urban railways, and various types of rail transit. This embodiment uses a CAD-based environmental vibration impact assessment of railway and rail transit projects as an example for illustration.

[0067] In some embodiments, a basic database is constructed based on project information and source strength information, including: acquiring project parameters, terrain data, engineering demolition boundary lines, and acoustic environment functional zoning tables; acquiring source strength data stored according to boundary conditions; and constructing a basic database based on the project parameters, terrain data, engineering demolition boundary lines, acoustic environment functional zoning tables, and source strength data.

[0068] Specifically, a basic database is built through a database module, which includes a project information component and a source strength information component.

[0069] For example, project information includes, but is not limited to, the predicted overall route plan, chain break table, bridge table, tunnel table, gradient table, station table, train model and rolling stock information, train operation organization information, topographic map of a certain area on both sides of the route (including buildings sensitive to environmental vibration), the red line of the demolition area, and the acoustic environment functional zoning table. Among them, buildings sensitive to environmental vibration can be buildings used for residential, scientific research, medical and health, cultural and educational, government and institutional offices, social welfare, etc. The red line of the demolition area indicates the boundary line for house expropriation and demolition determined by the implementation of the project. The topographic map of a certain area on both sides of the route includes, but is not limited to, ground elevation, building plan projection and building number of floors, sensitive point names, etc.

[0070] For example, source strength information includes source strength information for bridge sections and ground sections under corresponding boundary conditions listed in test reports and guidance documents issued by relevant departments; source strength information for bridge sections and ground sections under corresponding boundary conditions measured in currently operating railway and rail transit projects; and source strength information for bridge sections and ground sections under corresponding boundary conditions provided by manufacturers for test sections. This source strength information can be continuously supplemented and improved based on the information sources. Corresponding boundary conditions represent track type, bridge type, vehicle type, axle load, speed, turning radius, and track bed type. Measured source strength information also includes information on the administrative region where the test was conducted. Track type includes bridges, roadbeds, and tunnels. Track bed type includes ballasted track and ballastless track.

[0071] In one example, parameters such as the left and right lines of the engineering route and the starting point of the route are defined, while parameters such as the broken chain table, bridge table, and tunnel table are imported from the database.

[0072] In some embodiments, the process of capturing and identifying sensitive point information of environmental vibration-sensitive buildings based on the basic database to obtain a final sensitive point table includes: extracting sensitive point information of environmental vibration-sensitive buildings based on the basic database; analyzing and calculating the captured sensitive point information to generate a preliminary sensitive point table; and correcting and adjusting the preliminary sensitive point table to generate a final sensitive point table.

[0073] In some embodiments, extracting sensitive point information of environmental vibration-sensitive buildings based on the basic database includes: extracting terrain data and engineering demolition boundary lines based on the basic database; capturing the planar contours of environmental vibration-sensitive buildings and the attribute information of the planar contours based on the terrain data and the engineering demolition boundary lines; and obtaining sensitive point information based on the planar contours and attribute information.

[0074] In some embodiments, the captured sensitive point information is analyzed and calculated to generate a preliminary sensitive point table, including: performing mileage analysis, distance calculation, and acoustic environment functional zone analysis on the captured sensitive point information to obtain analysis results; merging adjacent or related buildings according to the analysis results to form preliminary sensitive points; and generating a preliminary sensitive point table based on the preliminary sensitive points.

[0075] Specifically, the information capture and recognition module includes an information capture and recognition component and a correction and adjustment component.

[0076] For example, the sensitive point information capture component includes three parts: sensitive point information capture, sensitive point identification, and correction adjustment. Sensitive point information capture involves capturing the planar outlines of buildings sensitive to environmental vibration on the topographic map based on the input requirements for the area on both sides of the route, combined with the engineering demolition boundary red line from the project information component in the database module, and marking them with a defined color on the topographic map. During sensitive point information capture, the captured planar outlines of environmentally vibration-sensitive buildings are also included in the database module, along with their name, location, nearest ground elevation, rooftop elevation, and number of floors. The input requirements for the area on both sides of the route refer to the evaluation range of this project, i.e., the maximum horizontal distance from the centerline of the outer track (i.e., the centerline of the left or right line).

[0077] Specifically, the sensitive point identification component further identifies the sensitive point information processed by the information capture component. It identifies sensitive point information based on factors such as distribution, location, name, and building characteristics to form a preliminary list of sensitive buildings. These identification factors include, but are not limited to, the corresponding floor number and location information of the building's floor plan in the database module.

[0078] For example, the extracted preliminary sensitive point buildings undergo calculations including but not limited to mileage analysis, horizontal distance calculation from the track, elevation difference calculation from the track surface, sensitive point name analysis, acoustic environment functional zone analysis, and number of floors analysis. After completing the building analysis, the sensitive point buildings are merged, and the merged sensitive points are given a unified name in the preliminary sensitive point table.

[0079] In one example, environmental vibration-sensitive buildings within a certain number of houses on both sides of the railway line are identified and extracted, including parameters such as building location, name, and number of floors. The environmental vibration-sensitive buildings undergo various functional operations, including mileage analysis, horizontal distance analysis, functional area analysis, administrative division analysis, sensitive point name analysis, sensitive point sequence number analysis, number of floors analysis, ground elevation analysis, rooftop elevation analysis, and number of households analysis. The sensitive buildings are then merged to form a preliminary environmental vibration-sensitive point table, and the number of households at different horizontal distances from the railway line is counted.

[0080] In some embodiments, the method further includes: automatically selecting the nearest building in the first row facing the line as a monitoring point from the merged sensitive points based on the preliminary sensitive point table; or, based on the preliminary sensitive point table, selecting the first floor of the building closest to the line outside the functional area boundary of the next functional area in the subsequent row as a monitoring point according to the functional area order.

[0081] Specifically, after sensitive points are generated, environmental vibration monitoring / prediction points are arranged on the ground floor of the nearest building in the first row facing the line, and the nearest building in the first row facing the line in different functional areas of the following row. Environmental vibration point placement can also be done manually. The logic for environmental vibration point placement is as follows: the nearest building in the first row is the planar outline of the environmental vibration sensitive building with the closest horizontal distance to the line among the merged sensitive points, and it is marked with a defined color on the topographic map. The nearest building in the first row facing the line in the following row is the nearest building outside the boundary line of the next sequential functional area among the merged sensitive points; and it is marked with a defined color on the topographic map.

[0082] For example, the next-order functional zone boundary line refers to the next sequence line of either the 4b or 4a category of the functional zone boundary lines at the location of the sensitive point in the database. That is, for example, if there is only a 2-category zone, the next-order functional zone boundary line is simply the nearest environmental vibration-sensitive building plan outline outside the 2-category zone line, and it is marked with a defined color on the topographic map. The functional zones are arranged in the order of 4b > 4a > 3 > 2 > 1 > 0, and the overlapping functional zones are those with higher order.

[0083] In one example, environmental vibration monitoring points are set up as follows: After the environmental vibration sensitive points are generated, the environmental vibration monitoring / prediction points are set up on the first floor of the nearest building in the first row facing the line and the first floor of the nearest building in the first row facing the line in different functional areas in the back row. The environmental vibration points can also be set up manually.

[0084] Specifically, the correction and adjustment component is the manual adjustment window. Operations are performed on the preliminary sensitive point table formed by the identification component. Based on the actual situation on site, sensitive points can be further merged, split, deleted, and corrected in terms of mileage, name, distance, elevation, etc., to obtain the final sensitive point table.

[0085] For example, sensitive point correction: the preliminary sensitive point list can be further merged, split, deleted, mileage corrected, name corrected, distance corrected, elevation corrected, etc., based on the actual situation on site to obtain the final sensitive point list.

[0086] In some embodiments, comparing project parameters with source strength data based on the basic database to filter out predicted input source strengths includes: extracting project parameters and source strength data based on the basic database; comparing the project parameters with the source strength data according to a preset priority, filtering and selecting matching source strength data as predicted input source strengths.

[0087] In some embodiments, an environmental vibration prediction calculation is performed based on the final sensitive point table, the predicted input source strength, and the monitoring point location to generate an environmental vibration prediction result table.

[0088] Specifically, the environmental vibration prediction module includes a source strength selection component and a calculation component.

[0089] For example, the main function of the source strength selection component is to select a suitable source strength as the prediction input source strength by comparing information such as track type, bridge type, vehicle type, vehicle axle load, vehicle speed, track straightness or curve radius, and track bed type in the project information group and source strength information component in the database module. The priority (preset priority) of the source strength selection comparison information can be manually defined in the aforementioned comparison information.

[0090] For example, the calculation component generates an environmental vibration prediction result table based on the final sensitive point table and its built-in environmental vibration prediction calculation method. It performs environmental vibration prediction calculations based on the coordinates, distances, elevation information, and predicted source strength from the final sensitive point table, generating the environmental vibration prediction result table. The built-in environmental vibration prediction calculation method includes vibration prediction calculation methods entered according to relevant national requirements, standards, and guidelines. It can calculate environmental vibrations and, based on the specified vibration reduction measures, calculate the type and length of vibration reduction measures to be taken at the line at the sensitive points exceeding the standard. The daytime standard value and nighttime standard value are environmental vibration values ​​that meet the requirements of the functional area, derived from the sensitive point functional area information. The daytime exceedance is the daytime environmental vibration value minus the daytime standard value. The nighttime exceedance is the nighttime environmental vibration value minus the nighttime standard value.

[0091] In one example, environmental vibration prediction: After configuring prediction parameters such as environmental vibration source intensity, train type, train length, and train operation organization, environmental vibration prediction evaluation can be performed. The prediction analysis can export data such as correction items and prediction results in a standard format (e.g., Excel format).

[0092] For example, the geometric and attribute parameters of each sensitive point are read from the final sensitive point table, including the mileage marker of the corresponding line, the horizontal distance from the line, the elevation difference from the rail surface, the number of floors, etc.; simultaneously, the vibration source intensity data of the corresponding road segment determined by the source intensity selection component is read. The read geometric parameters, attribute parameters, and vibration source intensity data are substituted into the built-in environmental vibration prediction calculation formula or model that conforms to relevant requirements and specifications. Based on the built-in environmental vibration prediction calculation method, the predicted environmental vibration values ​​for each sensitive point during the day and night are calculated. According to the acoustic environment functional zone information of the location of the sensitive point, the corresponding daytime and nighttime environmental vibration standard values ​​are obtained for standard comparison. The environmental vibration exceeding the standard during the day and night is calculated by comparison (e.g., subtracting the standard value from the predicted value), and all the above calculation results are summarized to generate an environmental vibration prediction result table.

[0093] In some embodiments, generating a plan view of measures based on the environmental vibration prediction result table and outputting an environmental vibration prediction layout map and a plan view of measures includes: automatically calculating the required vibration reduction measures type and length for sensitive points that are predicted to exceed the standard based on the environmental vibration prediction result table, and generating a final measure table; generating a plan view of measures based on the final measure table; generating an environmental vibration prediction layout map based on the location and number of environmental vibration monitoring points; and outputting the plan view of measures and the environmental vibration prediction layout map.

[0094] Specifically, the environmental vibration prediction and mitigation measures module includes prediction and mitigation measures components. The prediction and mitigation measures components will retrieve the prediction result table (environmental vibration prediction result table) from the automatic point detection and environmental vibration prediction module based on the environmental vibration data input obtained from the automatic point detection and environmental vibration prediction module, and generate an environmental vibration prediction table and a final measures table.

[0095] For example, the environmental vibration prediction table includes, but is not limited to, the starting point of the corresponding line's mileage marker, the ending point of the corresponding line's mileage marker, sensitive point floor information, horizontal distance from the line, elevation difference from the rail surface, sensitive point functional area information, vehicle speed, predicted daytime environmental vibration value, predicted nighttime environmental vibration value, daytime standard value, nighttime standard value, daytime exceedance of environmental vibration, and nighttime exceedance of environmental vibration. The daytime exceedance of environmental vibration is the predicted daytime environmental vibration value for the same sensitive point minus the daytime standard value. The nighttime exceedance of environmental vibration is the predicted nighttime environmental vibration value for the same sensitive point minus the nighttime standard value.

[0096] For example, the final measures table includes, but is not limited to, the name of the sensitive point, the type of measure, the starting point of the corresponding line's mileage marker, the ending point of the corresponding line's mileage marker, the floor information of the sensitive point, the horizontal distance from the line, the height difference from the rail surface, the functional area information of the sensitive point, the vehicle speed, the predicted value of daytime environmental vibration, the predicted value of nighttime environmental vibration, the standard value of daytime environmental vibration, the standard value of nighttime environmental vibration, the amount of daytime environmental vibration exceeding the standard, the amount of nighttime environmental vibration exceeding the standard, the starting point of the mileage marker of the line corresponding to the vibration reduction measures, and the ending point of the mileage marker of the line corresponding to the vibration reduction measures.

[0097] It should be noted that the environmental vibration prediction point map output can automatically generate an environmental vibration prediction point map with a standard map frame size based on the location and number of environmental vibration prediction points, and can be automatically exported as a PDF atlas after generation.

[0098] In one example, environmental vibration mitigation measures analysis involves conducting a compliance analysis based on environmental vibration prediction results. Different types of environmental vibration mitigation measures are implemented at sensitive points that do not meet the standards, ensuring that the predicted values ​​meet the standards after the measures are taken. The measures analysis can export data such as measure type, measure location, measure mileage, measure length, and post-measure prediction results in a standard format (e.g., Excel format). Environmental vibration measures mapping: A standard-size plan view of the measures can be automatically generated based on the location and length of the vibration reduction measures, and the generated plan view can be automatically exported as a PDF atlas.

[0099] It should be noted that the method in this embodiment integrates various engineering information and source strength information through a database module, improving the automation and efficiency of data processing. This enables rapid import and management of line parameters and sensitive point information, reducing manual intervention and significantly improving work efficiency. The information capture and identification module automatically extracts and analyzes sensitive point information, combined with automatic point placement and calculation functions, enhancing the accuracy of prediction and evaluation. This avoids repetitive work and human errors caused by engineering adjustments in traditional manual compilation, ensuring the accuracy of evaluation results. The system can automatically generate standardized environmental vibration prediction point maps and measure planar diagrams based on sensitive point information and vibration reduction measures, supporting export in PDF and Excel formats. When engineering alignments or parameters change, the system can quickly update relevant charts and data, significantly reducing the manpower and material costs of rework and enhancing the responsiveness to changes in drawing and engineering.

[0100] This embodiment provides a method for assessing the environmental vibration impact of rail transit projects, including: constructing a basic database based on project information and source strength information; capturing and identifying sensitive point information of vibration-sensitive buildings based on the basic database to obtain a final sensitive point table; comparing project parameters with source strength data based on the basic database to filter out predicted input source strengths; performing environmental vibration prediction calculations based on the final sensitive point table, predicted input source strengths, and monitoring points to generate an environmental vibration prediction result table; generating a measure plan based on the environmental vibration prediction result table, and outputting an environmental vibration prediction layout map and a measure plan. This embodiment integrates various project information and source strength information through a basic database, enabling rapid import and management of line parameters and sensitive point information, improving the automation and efficiency of data processing, reducing manual intervention, and significantly improving work efficiency. Utilizing information capture and identification to automatically extract and analyze sensitive point information, combined with automatic point layout and calculation functions, avoids human error and improves the accuracy of prediction and assessment. Automatically generating standardized environmental vibration prediction layout maps and measure plan maps enhances mapping responsiveness.
