[0001] The present application relates to the technical field of settlement measurement, and in particular to a method, system, medium and equipment for measuring the settlement of a dike foundation section. Background Art

[0002] In engineering construction, especially the construction of levee projects, the stability of the levee is crucial to ensure the safety and functionality of the project. The structural stability of the levee directly affects the flood control effect and the safety of the surrounding environment.

[0003] Conventional embankment foundation section settlement measurement technology mainly relies on the use of settlement plates, which are usually buried at the embankment shoulders and the platforms on both sides to monitor the settlement of the embankment at different locations. During the construction process, these settlement plates are supported by bagged sand blowing technology, and the measuring tubes and protective tubes need to be manually extended to ensure the function of the settlement plates. The verticality of the measuring tube is difficult to accurately control during the installation process. Once tilted, it will directly affect the accuracy of the settlement observation data. The tilted measuring tube may cause deviations in the observation results, resulting in low accuracy in the settlement measurement of the embankment foundation section. Summary of the invention

[0004] The present application provides a method, system, medium and equipment for measuring the cross-sectional settlement of a levee foundation, which can improve the accuracy of the cross-sectional settlement measurement of the levee foundation.

[0005] In a first aspect, the present application provides a method for measuring the cross-section settlement of a dike foundation, the method comprising: Acquire the horizontal angle currently collected by each measuring segment in the array displacement meter, each of the measuring segments being installed on the surface of the embankment foundation section at a preset interval; A calculation is performed based on the horizontal angle and the length of each measuring segment to obtain a target settlement of each measuring segment; a cross-sectional settlement diagram is generated based on the target settlement of each measuring segment, and the safety status of the embankment foundation is determined based on the cross-sectional settlement diagram.

[0006] By adopting the above technical solution, an array displacement meter is used, and multiple measuring segments are installed on the embankment foundation section at preset intervals. This array point arrangement method can continuously obtain the settlement distribution on the entire embankment foundation section, avoiding the problems of scattered measuring points and measurement blind spots in traditional methods, and comprehensively reflects the deformation state of the embankment foundation section. The calculation is based on the method of horizontal angle and segment length to obtain a more accurate target settlement, and effectively eliminates the observation deviation caused by the tilted installation position of the measuring segment, thereby significantly improving the accuracy and reliability of the cross-section settlement measurement, and generates a cross-section settlement diagram based on the target settlement of each measuring segment, and the current safety status of the embankment foundation can be accurately judged based on the cross-section settlement diagram, effectively improving the accuracy of the embankment foundation section settlement measurement.

[0007] Optionally, each measuring segment is equipped with a MEMS accelerometer, and the step of acquiring the horizontal angle collected by each measuring segment in the array displacement meter includes: Acquiring tilt data collected by each of the MEMS accelerometers; The horizontal angle is extracted from the tilt data.

[0008] By adopting the above technical solution, the MEMS accelerometer is integrated and installed in each measuring segment. By acquiring the tilt data collected by the accelerometer, the horizontal angle can be directly extracted from the tilt data, which overcomes the complex operation steps of the traditional method that requires manual extension of the measuring tube and the protective tube, greatly reduces the construction workload, improves the measurement efficiency, and can eliminate the influence of the observation deviation caused by the tilt of the measuring tube, with high measurement accuracy and strong reliability.

[0009] Optionally, the calculating based on the horizontal angle and the length of each measuring segment to obtain the target settlement amount of each measuring segment includes: Taking the first measurement segment as the starting point, obtaining the starting elevation of each measurement segment; Substituting the horizontal angle and the length corresponding to each measuring segment of the starting elevation into a preset calculation formula to obtain the target settlement amount of each measuring segment; The calculation formula is: In the formula, ΔH i is the target settlement of the ith measurement segment, is the absolute deviation of the jth measurement segment relative to the starting point, is the initial absolute deviation of the nth measurement segment relative to the starting point; Δh is the starting elevation, l is the length of the measurement segment, θ i is the jth horizontal angle of the nth measurement segment, and θ0 is the initial angle of the nth measurement segment relative to the horizontal plane.

[0010] By adopting the above technical solution, the influence of the horizontal angle deviation caused by the tilted installation position of the measuring segment on the initial settlement is accurately considered, and it is corrected by the geometric calculation method of vector synthesis, which fundamentally eliminates the systematic error caused by the installation tilt and significantly improves the accuracy and reliability of settlement measurement.

[0011] Optionally, generating a cross-sectional settlement diagram based on the target settlement amount of each measurement segment includes: Constructing a two-dimensional coordinate system, wherein the horizontal axis of the two-dimensional coordinate system is the horizontal position of the measuring segment, and the vertical axis is the settlement amount; Plotting the target settlement amount of each measuring segment as scattered points; The scattered points are connected to obtain the cross-sectional settlement diagram.

[0012] By adopting the above technical solution, a vivid and intuitive cross-sectional settlement diagram was generated using a two-dimensional coordinate system. It not only fully demonstrated the deformation trend of the entire embankment cross section, but also facilitated the intuitive comparison and analysis of the deviation between the settlement and the design contour line, providing an efficient and visual criterion for judging the stability status of the embankment foundation.

[0013] Optionally, determining the safety status of the embankment foundation based on the cross-sectional settlement diagram includes: Extracting the maximum settlement amount in the cross-sectional settlement diagram; Calculate the settlement deviation between adjacent measurement segments in the cross-sectional settlement diagram; Based on the maximum settlement and the settlement deviation, construct a levee foundation safety evaluation index; The safety status of the embankment foundation is determined based on the safety evaluation index.

[0014] By adopting the above technical scheme, a levee foundation safety evaluation system was established based on the maximum settlement and settlement deviation. Compared with the existing technology, not only is the evaluation process more scientific and standardized, but the indicator system is also more comprehensive and complete, laying a solid foundation for accurately determining the current stability status of the levee foundation.

[0015] Optionally, determining the safety status of the embankment foundation based on the safety evaluation index includes: Comparing the safety evaluation index with a corresponding safety threshold; If all safety evaluation indicators do not exceed the corresponding safety thresholds, the embankment foundation is determined to be in a safe state; If any safety evaluation index exceeds the corresponding safety threshold, the embankment foundation is determined to be in a warning state; If the number of safety evaluation indicators exceeding the safety threshold is greater than a preset number, it is determined that the embankment foundation is in a dangerous state.

[0016] By adopting the above technical solution and a hierarchical status determination method, three risk levels, namely safety, warning and danger, are distinguished. The guiding significance is clear and it is convenient to formulate appropriate subsequent prevention and control measures.

[0017] Optionally, the method further includes: Collecting loading parameters of the measurement area, wherein the loading parameters include fill height and fill rate; generating load data based on the loading parameters; Calculating the correlation coefficient between the load data and the target settlement; The loading speed and loading height of the array displacement meter are controlled based on the correlation coefficient.

[0018] By adopting the above technical solution, by collecting loading parameters such as fill height and fill rate in the measurement area, generating a load data model, and calculating the correlation between the load data and the target settlement, the loading process of the array displacement meter can be reasonably controlled to achieve the expected settlement effect, providing digital technical support for the reasonable regulation of the loading process.

[0019] In a second aspect of the present application, a system for measuring the cross-section settlement of a dike foundation is provided, the system comprising: A settlement acquisition module is used to acquire the horizontal angle currently collected by each measuring segment in the array displacement meter, each of which is installed on the surface of the embankment foundation section at a preset interval; A settlement correction module, used for calculating based on the horizontal angle and the length of each measuring segment to obtain a target settlement of each measuring segment; The settlement diagram generation module is used to generate a cross-sectional settlement diagram based on the target settlement amount of each measurement segment, and determine the safety status of the embankment foundation based on the cross-sectional settlement diagram.

[0020] In a fourth aspect of the present application, an electronic device is provided, comprising: a processor and a memory; wherein the memory stores a computer program, and the computer program is suitable for being loaded by the processor and executing the above-mentioned method steps.

[0024] In order to enable technicians in this field to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0025] In the description of the embodiments of the present application, words such as "for example" or "for example" are used to indicate examples, illustrations or explanations.

Specifically, the use of words such as "for example" or "for example" is intended to present related concepts in a specific way.

[0026] In the description of the embodiments of the present application, the meaning of the term "multiple" refers to two or more. For example, multiple systems refer to two or more systems, and multiple screen terminals refer to two or more screen terminals. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. The terms "include", "comprise", "have" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0027] The following will provide a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0028] See also Figure 1 , is a schematic diagram of burying settlement points of a dyke foundation using a settlement plate for settlement measurement provided in an embodiment of the present application.

[0029] At present, the surface settlement of the levee foundation is usually observed by using settlement plates, which are generally buried at the levee shoulders and the platforms on both sides. Its production mainly includes: the base is made of 100cm×100cm×10mm steel plate, and a 1.5-inch galvanized steel pipe is welded at the center of the steel plate surface as a measuring pipe. The verticality of the measuring pipe is 90°, and the bottom of the measuring pipe must be firmly welded to the steel plate; a φ20mm (L=400mm) steel bar is welded at each of the four corners under the steel plate. Its installation mainly includes: inserting the steel bars of the base into the levee foundation soil in the design, and using bagged sand to press on the top of the steel plate for fixing. After installation, the measuring pipe should remain vertical; the measuring pipe is protected by a 1.5-inch galvanized steel pipe to ensure the freedom of the measuring pipe in the protective pipe; during the construction of the levee filling, the measuring pipe and the protective pipe are extended every 1m. The settlement observation of the settlement plate is generally implemented by the GNSS RTK method, and the current settlement and cumulative settlement are calculated based on the initial elevation of the measuring pipe, the previous elevation and the current elevation. Observe the cumulative settlement before measuring pipe extension, and observe the new initial elevation after extension. The cumulative settlement after extension should include the cumulative settlement before extension.

[0030] However, although the use of settlement plates for settlement measurement can basically reflect the surface settlement at the designed position of each section of the embankment foundation, it has many defects. For example, the settlement plate method requires manual extension of the measuring tube and the protective tube during the bagged sand filling process, and the installation period is long; the verticality of the measuring tube is difficult to control during construction, and the accuracy of the observed settlement is reduced after excessive inclination.

[0031] Please refer to Figure 2 , a flow chart of a method for measuring the cross-section settlement of a dike foundation is proposed. The method can be implemented by a computer program, a single-chip microcomputer, or run on a dike foundation cross-section settlement measurement system. The computer program can be integrated into a computer device or run as an independent tool application. Specifically, the method includes steps 10 to 30, and the steps are as follows: Step 10: Obtain the horizontal angle currently collected by each measuring segment in the array displacement meter, and each measuring segment is installed on the surface of the embankment foundation section at a preset interval.

[0032] An array displacement meter is a linear monitoring device composed of multiple continuously arranged measuring units. It is a precision instrument specially designed to monitor the surface settlement of the embankment foundation. The characteristic of the array displacement meter is that it can provide continuous and high-resolution displacement data. In this embodiment, the array displacement meter is installed on the cross section of the embankment foundation to monitor the settlement of the embankment foundation in real time.

[0033] A measurement segment refers to a single measurement unit in an array displacement meter. Each measurement segment is usually 1 meter long and contains precision sensors (such as MEMS accelerometers). These sensors can capture tiny displacement changes and tilt angles. The measurement segment is the basic component of the array displacement meter. Multiple measurement segments are connected together to form a complete array displacement meter.

[0034] In the embodiment of the present application, the embankment foundation section refers to the vertical section of the embankment foundation. This section is an imaginary plane that vertically cuts through the embankment foundation and shows the structure and shape of the embankment foundation from the bottom to the top. Selecting a suitable embankment foundation section for monitoring is crucial to fully understand the settlement of the embankment foundation. Usually, multiple representative embankment foundation sections are selected for monitoring to obtain a comprehensive picture of the embankment foundation settlement.

[0035] Specifically, in order to achieve high-precision and continuous monitoring of the settlement of the surface section of the levee foundation, we use array displacement meters for measurement. The array displacement meter consists of multiple measurement segments, which are installed on the levee foundation section at preset intervals. The purpose of selecting the preset interval installation is to ensure the spatial resolution and representativeness of the monitoring data. The length of each measurement segment is usually set to 1 meter, so that continuous and complete settlement data for every 1 meter of the levee foundation surface can be obtained. During the installation process, first select a suitable monitoring position along the levee foundation section, taking into account the geometric characteristics of the levee foundation and possible weak areas. Then, a protective ABS inclinometer tube is laid along the levee foundation surface at the selected location. This inclinometer tube can protect the internal measurement equipment from interference from the external environment. Next, the array displacement meter is inserted into the ABS inclinometer tube to ensure that each measurement segment corresponds precisely to its predetermined position. After the installation is completed, the measurement segments are connected through an automated collector to form a complete monitoring system.

[0036] Before construction begins, the system will automatically collect initial data for each measurement segment, which will serve as a reference point for subsequent settlement calculations. Due to construction impacts or their own position tilt, these segments will have a certain angle deviation relative to the horizontal plane. Directly using the measured values ​​for analysis will result in a large system error. The acquisition process of the horizontal angle is automated. The collector will complete the data reading of all measurement segments within a preset time, usually within 1 minute, to obtain the horizontal angle collected by each measurement segment. Since a high-precision inclination sensor is built into the displacement meter of each measurement segment, the sensor uses the principles of gyroscopes, accelerometers, etc. to accurately measure the current inclination angle of the segment relative to the horizontal plane.

[0037] Based on the above embodiment, as an optional embodiment, the step of obtaining the initial settlement amount collected by each measuring segment in the array displacement meter may further include the following steps: Step 101: Obtain tilt data collected by each MEMS accelerometer.

[0038] Specifically, a MEMS accelerometer is installed in each measuring segment. The MEMS (micro-electromechanical system) accelerometer has the characteristics of high precision, miniaturization and low power consumption, and is suitable for long-term and continuous monitoring of embankment settlement. Each measuring segment is equipped with a MEMS accelerometer to capture tiny tilt angles. After the array displacement meter is installed, the system will be initialized. At this stage, each MEMS accelerometer will collect tilt data in its initial state. These data reflect the initial position and posture of each measuring segment on the embankment. The collection process is automatic, and the data reading of all measuring segments is completed in a short time (usually no more than 1 minute) through a pre-set data collector. The MEMS accelerometer determines its spatial posture by measuring the components of gravity acceleration in three axes, and the tilt data can be directly calculated from the output of the accelerometer.

[0039] Step 102: extracting the horizontal angle from the tilt data.

[0040] Specifically, the system receives the tilt data from the MEMS accelerometers of each measurement segment, which represents the tilt angle of the measurement segment relative to the horizontal plane. The tilt data collected in real time by the MEMS accelerometers of each segment will be uploaded to the data processing system of the monitoring center via wireless transmission. The system analyzes and geometrically calculates the tilt data to accurately extract the current horizontal angle of each measurement segment.

[0041] Step 20: Calculate based on the horizontal angle and the length of each measuring segment to obtain the target settlement amount of each measuring segment.

[0042] The horizontal angle of each measuring segment refers to the angle between each measuring segment and the horizontal plane, which is the angle between the axis of the measuring segment and the horizontal plane. This angle reflects the degree of inclination of the measuring segment. In practical applications, the horizontal angle is a dynamically changing value, because the settlement of the embankment foundation will cause the posture of the measuring segment to change.

[0043] The length of the measuring segment refers to the actual length of each individual measuring unit. In this application, this is usually a fixed value, such as 1 meter. This length is the basic unit of the array displacement meter and is also an important parameter for calculating the settlement.

[0044] The target settlement refers to the actual settlement of each measuring segment obtained after correction and calculation.

[0045] Specifically, the horizontal angle is obtained by the MEMS accelerometer built into each measuring segment. The measurement of the horizontal angle is performed dynamically because the settlement of the embankment foundation will cause the continuous change of the attitude of the measuring segment. At the same time, the length of the measuring segment is input into the system as a preset parameter, usually 1 meter. The accurate acquisition of these two parameters is crucial for the subsequent settlement calculation because they directly affect the actual projection length of the measuring segment in the vertical direction.

[0046] Then, using a pre-set mathematical formula, the horizontal angle and length are combined to calculate the settlement. This calculation process takes into account the impact of the geometric changes of the measuring segment on the settlement measurement. Specifically, the system uses trigonometric function relationships to calculate the change in the projection length of the measuring segment in the vertical direction according to the change in the horizontal angle. This method can accurately reflect the additional vertical displacement caused by the inclination of the measuring segment, thereby improving the accuracy of the settlement calculation. Finally, the corrected target settlement of each measuring segment is obtained. This target settlement not only includes the initial measured settlement data, but also comprehensively considers the posture changes and geometric characteristics of the measuring segment, so it can more accurately reflect the actual settlement of the embankment foundation.

[0047] Based on the above embodiment, as an optional embodiment, the step of calculating based on the horizontal angle and the length of each measuring segment to obtain the target settlement amount of each measuring segment may also include the following steps: Step 201: Taking the first measurement segment as the starting point, obtain the starting elevation of each measurement segment.

[0048] Specifically, first use a high-precision level to measure the first measuring segment to determine its absolute elevation. This elevation value will serve as the reference point for the entire measurement system. Subsequently, by utilizing the characteristics of the array displacement meter and measuring the elevation difference between adjacent segments, the starting elevation of other measuring segments can be gradually calculated. In specific operations, the MEMS accelerometer built into the array displacement meter can be used to measure the inclination of each segment relative to the horizontal plane, and then combined with the known segment length, the elevation difference between adjacent segments can be calculated through trigonometric functions. This method not only simplifies the measurement process, but also ensures the continuity and consistency of the measurement. By comparing the latest measured elevation with the initial elevation, the system can calculate the cumulative settlement of the starting point, and can also obtain the current settlement amount by the difference between the current elevation and the previous elevation.

[0049] Step 202: Substitute the starting elevation, the horizontal angle and the length corresponding to each measuring segment into a preset calculation formula to obtain the target settlement of each measuring segment.

[0050] like Figure 3 The figure shows a schematic diagram of the settlement calculation principle of an array displacement meter provided in an embodiment of the present application.

[0051] Specifically, the starting elevation, the horizontal angle and the length corresponding to each measuring segment are substituted into a preset calculation formula to obtain the target settlement of each measuring segment.

[0052] The calculation formula is: In the formula, ΔH i is the target settlement of the ith measurement segment, is the absolute deviation of the jth measurement segment relative to the starting point, is the initial absolute deviation of the nth measurement segment relative to the starting point; Δh is the starting elevation, l is the length of the measurement segment, θ i is the jth horizontal angle of the nth measurement segment, and θ0 is the initial angle of the nth measurement segment relative to the horizontal plane.

[0053] The core idea of ​​this formula is to correct the initial settlement by considering the geometric changes of the measuring segment, so as to obtain a more accurate target settlement, taking into account the change in the inclination angle and length of the measuring segment, as well as the starting elevation of the starting point.

[0054] This formula can be divided into two main parts: Part I: It indicates the change of settlement relative to the starting point, and their difference reflects the actual settlement during the measurement period. The relative settlement change can be obtained by l· The vertical displacement caused by the change in the angle of the measuring segment is calculated. The second part: Δh is the starting elevation of the starting point, which is a correction for the possible settlement of the starting point itself, which ensures the accuracy of the entire measurement system relative to a fixed reference point.

[0055] By combining these three parts, the calculation formula can accurately calculate the actual settlement of each measuring segment. It not only takes into account the settlement data measured directly, but also takes into account the measurement errors that may be caused by geometric changes (such as tilt) of the measuring equipment itself, as well as changes in the benchmark points of the entire measuring system. It can provide high-precision settlement estimates, especially in long-term monitoring or complex terrain. By considering multiple influencing factors, it can more accurately reflect the actual settlement of the embankment foundation, providing a reliable data basis for evaluating the safety of the embankment foundation and guiding construction.

[0056] Step 30: Generate a cross-sectional settlement diagram based on the target settlement amount of each measuring segment, and determine the safety status of the embankment foundation based on the cross-sectional settlement diagram.

[0057] The cross-sectional settlement diagram refers to a graphical representation generated based on the target settlement data of each measuring segment, that is, a two-dimensional chart. The horizontal axis represents the horizontal distance of the embankment section or the position of the measuring segment, and the vertical axis represents the settlement. It intuitively shows the settlement of each point on the embankment section and can clearly reflect the distribution characteristics and changing trends of the settlement.

[0058] The safety status of the embankment foundation refers to the current stability assessment result of the embankment foundation obtained based on the cross-sectional settlement diagram and other relevant data analysis. In the embodiment of the present application, the safety status of the embankment foundation is generally divided into the following levels: safe state, alert state and dangerous state.

[0059] Specifically, the system collects and organizes the target settlement data of each measuring segment, including the influence of factors such as horizontal angle and length, so it can accurately reflect the actual settlement of each point on the embankment foundation. Next, use these data to construct a two-dimensional coordinate system, in which the horizontal axis represents the horizontal position of the measuring segment on the embankment foundation section, and the vertical axis represents the settlement. The system plots the target settlement of each measuring segment as scattered points, and then connects these scattered points to form a settlement curve. In addition, the system also annotates time information, scale, and key data points to enhance the information content and readability of the chart. The purpose of generating a cross-sectional settlement map is to convert complex numerical data into an intuitive graphical representation. This visualization method enables engineers to quickly identify areas of abnormal settlement, understand the spatial distribution characteristics of settlement, and observe the temporal evolution of settlement trends.

[0060] Based on the generated cross-sectional settlement diagram, the safety status of the levee foundation is further analyzed and determined. The system extracts key features from the settlement diagram, such as the maximum settlement and its location, the slope of the settlement curve (reflecting the settlement rate), etc. The system then compares these features with preset safety thresholds. These thresholds are pre-set based on engineering experience and specific project requirements, reflecting different degrees of safety risks. The safety status of the levee foundation is determined by comparing the results. Each status corresponds to a specific settlement feature and risk level, accompanied by corresponding recommended measures.

[0061] Based on the above embodiment, as an optional embodiment, the step of generating a cross-sectional settlement diagram based on the target settlement amount of each measurement segment may further include the following steps: Step 3011: construct a two-dimensional coordinate system, the horizontal axis of which is the horizontal position of the measurement segment, and the vertical axis is the settlement amount.

[0062] Specifically, the range of the coordinate system is determined according to the installation conditions of the array displacement meter and the actual size of the embankment. The range of the horizontal axis usually starts from the position of the first measuring segment and extends to the position of the last measuring segment, covering the entire monitoring section. The range of the vertical axis is set according to the expected maximum and minimum settlements, and a certain margin is usually left to deal with possible abnormal settlements. Draw the coordinate axis and scale lines in the coordinate system. The scale on the horizontal axis represents the distance along the embankment section, usually in meters; the scale on the vertical axis represents the settlement, in millimeters or centimeters, depending on the scale of the settlement. In order to improve accuracy and readability, the system may use different scale densities, such as using denser scales in key areas, and adding clear labels to the coordinate axes, including unit information and the physical meaning of the axis (such as "distance (m)" and "settlement (mm)").

[0063] Step 3012: Plot the target settlement amount of each measurement segment as scattered points.

[0064] Step 3013: Connect the scattered points to obtain a cross-sectional settlement diagram.

[0065] Specifically, in the two-dimensional coordinate system constructed above, the target settlement data of each measuring segment is plotted as scattered points. The abscissa of each scattered point corresponds to the horizontal position of the measuring segment on the embankment foundation section, and the ordinate represents the target settlement of the segment. These scattered points intuitively display the settlement data obtained by actual measurement. Connecting these scattered points can generate a continuous settlement curve, thereby obtaining a cross-sectional settlement diagram.

[0066] like Figure 4 As shown, it is an exemplary sedimentation diagram provided in an embodiment of the present application.

[0067] Combination Figure 4 It can be seen that the horizontal axis of the cross-sectional settlement diagram is the distance to the starting point (m), and the vertical axis is the cumulative settlement (mm). The cumulative settlement is also the target settlement in the embodiment of the present application. Different colors represent different times. The figure shows the settlement distribution status of different periods.

[0068] Based on the above embodiment, as an optional embodiment, the step of determining the safety state of the embankment foundation based on the cross-sectional settlement diagram may further include the following steps: Step 3021: Extract the maximum settlement in the cross-sectional settlement diagram.

[0069] Specifically, based on the analysis of the continuous settlement curve data generated above, in order to extract the maximum settlement, the system will traverse all data points on the entire settlement curve, compare their settlement values, find the maximum value, obtain the maximum settlement, and record its value and its position coordinates on the embankment foundation section.

[0070] Step 3022: Calculate the settlement deviation between adjacent measurement segments in the cross-sectional settlement diagram.

[0071] Specifically, based on the cross-sectional settlement data generated above, the target settlement amount of each measuring segment is extracted. Then, the system compares the settlement amounts of adjacent measuring segments one by one and calculates the settlement deviation between them. The calculation formula for settlement deviation is: h = |S i -S i+1 | / L, where h is the settlement deviation, S i and S i+1 They represent the target settlement of two adjacent measuring segments, and L represents the horizontal distance between the two measuring segments.

[0072] Step 3023: Construct embankment foundation safety evaluation indicators based on the maximum settlement and settlement deviation.

[0073] Specifically, based on the maximum settlement and settlement deviation data, these raw data are converted into corresponding safety evaluation indicators. For the maximum settlement, the system constructs the maximum settlement safety index MSSI = Smax / Smax_critical, where Smax is the measured maximum settlement and Smax_critical is the critical maximum settlement determined according to engineering specifications and project requirements. For the settlement deviation, the system constructs the settlement uniformity index SDI = Dmax / Dmax_allowable, where Dmax is the measured maximum settlement deviation and Dmax_allowable is the maximum allowable settlement deviation. These two indicators each reflect different aspects of the safety status of the embankment foundation: MSSI reflects the most serious local settlement, while SDI reflects the uniformity of settlement.

[0074] Step 3024: Determine the safety status of the embankment foundation based on the safety evaluation index.

[0075] Specifically, the safety evaluation indicators calculated in the above steps are read, including but not limited to comprehensive indicators based on maximum settlement and settlement deviation. At the same time, the system will also load pre-set safety thresholds. These thresholds are determined based on engineering specifications, historical experience and specific project requirements, reflecting different degrees of safety risks. For each safety evaluation indicator, the system will compare it with the corresponding safety threshold. If all safety evaluation indicators do not exceed the corresponding safety threshold, the system will determine the state of the embankment foundation as a safe state, which indicates that all indicators of the embankment foundation are within an acceptable range and no special intervention measures are required. If any safety evaluation indicator exceeds the corresponding safety threshold, the system will determine the state of the embankment foundation as a warning state, which means that some abnormal conditions have occurred in the embankment foundation, which requires attention and may require preventive measures. If the number of safety evaluation indicators exceeding the safety threshold is greater than the preset number, the system will determine the state of the embankment foundation as a dangerous state, which indicates that the embankment foundation may face multiple risks and emergency measures need to be taken immediately.

[0076] Based on the above embodiment, as an optional embodiment, a method for measuring the cross-section settlement of a dike foundation may further include the following process: In practical applications, in order to better control and optimize the loading process of the levee foundation, this scheme first collects the loading parameters of the measurement area, including fill height and fill rate. These parameters directly reflect the load conditions borne by the levee foundation and are key factors affecting settlement. Then, based on these loading parameters, load data are generated, which can quantitatively represent the pressure on the levee foundation. Subsequently, the correlation coefficient between the load data and the target settlement is calculated. This step aims to analyze the strength of the relationship between load and settlement. Through this correlation coefficient, we can deeply understand the degree of influence of the loading process on settlement. Finally, based on the calculated correlation coefficient, the loading speed and loading height of the array displacement meter are controlled in real time.

[0077] Specifically, the filling height can be measured regularly using measuring equipment (such as laser rangefinder, GPS, etc.), while recording the filling time and calculating the filling rate. These raw data are input into the preset model to generate load data reflecting the stress condition of the embankment foundation. Then, the correlation coefficient between the load data and the target settlement is calculated using statistical methods (such as Pearson correlation coefficient). Finally, according to the size and positive and negative of the correlation coefficient, the loading speed and loading height of the array displacement meter are adjusted through the pre-set control algorithm. For example, if the correlation coefficient is large and positive, it means that the current loading has a significant impact on the settlement, and it may be necessary to reduce the loading speed or limit the loading height; on the contrary, if the correlation coefficient is small, the loading speed can be appropriately accelerated or the loading height can be increased. Accurate control of the loading process is achieved, avoiding excessive settlement or instability of the embankment foundation caused by blind loading. Secondly, by analyzing the relationship between load and settlement, the loading strategy can be optimized to improve construction efficiency while ensuring safety. In addition, this real-time control mechanism can respond to the dynamic changes of the embankment foundation in a timely manner, improving the adaptability and reliability of the entire system.
