[0023] See also Figure 2 The embodiment of the present invention provides a method for dividing standard soil layers according to geotechnical parameters, which may include the following steps: S201, collecting multiple geotechnical parameters of the target soil layer, wherein the geotechnical parameters at least include: soil density, water content, permeability coefficient, and shear strength; In the first step of this method, the goal is to collect multiple geotechnical parameters of a specific soil layer, which are crucial to understanding the physical properties of the soil. Soil density refers to the mass of soil per unit volume, which affects the bearing capacity and stability of the soil; moisture content refers to the proportion of water in the soil, which is directly related to the engineering properties and applicability of the soil; permeability is used to measure the ability of soil water to pass through, and is an important indicator for evaluating soil drainage performance; and shear strength is the ability of soil to resist deformation and damage when subjected to force, and is also a key parameter for evaluating soil strength characteristics. Through the collection of these geotechnical parameters, the physical properties of the soil layer can be comprehensively evaluated, providing the necessary data support for the subsequent soil layer division.

[0024] The process of collecting geotechnical parameters is an important basis for global soil layer analysis. These parameters can not only reflect the physical and mechanical properties of the soil, but also provide a scientific basis for engineering construction, soil improvement, soil and water conservation and other fields. By accurately grasping information such as soil density, moisture content, permeability coefficient and shear strength, engineers can evaluate the stability and bearing capacity of the soil layer, predict the deformation and settlement behavior of the soil, and take corresponding safety measures during the design and construction process. In addition, the analysis of these data can also help optimize soil use strategies, reduce resource waste, and improve the long-term sustainability of the project.

[0025] Specifically, select the target area for research and fully understand its geographical conditions and soil types for subsequent geotechnical parameter collection. According to the changes in soil properties, design a reasonable sampling point layout plan to ensure the representativeness of different soil layers in the coverage area. Use soil drilling equipment (such as manual or mechanical samplers) to sample at predetermined sampling points, ensuring multi-point sampling at different depths to obtain the physical parameters of each layer of soil. Use standardized test methods to measure soil density (such as dry density, saturated density), moisture content (such as drying method), permeability coefficient (such as conventional permeability test) and shear strength (such as direct shear test or triaxial test). Summarize the various geotechnical parameters obtained from the experiment and establish a complete geotechnical parameter data set for subsequent normalization and soil layer division.

[0026] S202, performing normalization processing on the collected geotechnical parameters, and constructing the processed normalized parameter set into a multidimensional parameter matrix, wherein each row in the multidimensional parameter matrix represents a parameter set of a sampling point, and each column represents a specific parameter; Normalization of the collected geotechnical parameters refers to standardizing multiple geotechnical parameters (such as soil density, moisture content, permeability, shear strength, etc.) so that they are within the same range (usually between 0 and 1). This processing is mainly done by calculating the minimum and maximum values ​​of each parameter and applying the normalization formula to convert the original data. The constructed multidimensional parameter matrix organizes the normalized parameter set of each sampling point to form a structure with rows and columns representing sampling points and parameters, respectively, to facilitate subsequent data analysis and model construction.

[0027] By normalizing the collected geotechnical parameters and constructing a multidimensional parameter matrix, the effects of dimensional differences between different parameters can be effectively eliminated. This consistency makes the parameters more comparable in subsequent data analysis, machine learning or model applications, and improves the reliability and stability of the model. The normalized multidimensional parameter matrix can not only help identify soil layer characteristics, but also improve the accuracy of data mining, providing a solid data foundation for soil layer division and feature analysis, and helping to gain a deeper understanding of the relationship between soil physical properties and engineering properties.

[0028] Specifically, after sampling the target soil layer, record the relevant geotechnical parameters, including soil density, moisture content, permeability, and shear strength. For each collected geotechnical parameter, calculate its minimum and maximum values ​​in all sampling points. This is the core step of normalization and provides basic data for subsequent normalization operations. Apply the normalization formula to the geotechnical parameters of each sampling point to convert each parameter into a standardized value. Specifically, for each parameter, traverse all sampling points, calculate its corresponding normalized value, and generate a new set of parameter values. Create a multidimensional parameter matrix in which each row represents a normalized parameter set for a sampling point, and each column corresponds to a specific geotechnical parameter (such as soil density, moisture content, permeability, shear strength, etc.). Check the multidimensional parameter matrix to ensure that all normalized parameter values ​​are between 0 and 1, and confirm the effectiveness and accuracy of the normalization process.

[0029] S203, determining a segmentation threshold function for dividing the standard soil layer, and calculating a change amount of the segmentation threshold function between adjacent sampling points for the sampling points in the multidimensional parameter matrix; In this method, determining the segmentation threshold function for dividing the standard soil layer is a key step in identifying soil layer changes. The segmentation threshold function integrates multiple geotechnical parameters (such as soil density, moisture content, permeability and shear strength) to establish a mathematical model, which is designed to reflect the characteristic changes between different soil layers. By calculating the change in the segmentation threshold function of adjacent sampling points in the multidimensional parameter matrix, we can effectively capture the slight changes in the soil layer, thereby providing the necessary basis for the subsequent soil layer division.

[0030] The implementation of this step helps to objectively quantify soil layer changes and ensure the scientificity and accuracy of soil layer division. By analyzing the changes in adjacent sampling points, the differences between soil layer characteristics can be quantitatively evaluated, thereby accurately locating the critical points of soil layer changes. This process not only improves the reliability of soil layer division, but also provides an important basis for engineering practice, especially in fields such as civil engineering and environmental engineering, where accurate soil layer division is crucial for structural design and construction scheme selection.

[0031] Specifically, a method for determining the segmentation threshold function may be: Among them, the is the soil density (reflects the compactness of the soil and affects the bearing capacity of the soil layer), moisture content (affects soil physical properties such as permeability and strength), permeability coefficient (determines the water flow characteristics of the soil layer and has a significant impact on hydrological conditions), shear strength (a measure of the ability of soil layers to resist sliding, which is crucial for stability analysis) segmentation threshold function, is a correction function used to more accurately reflect the nonlinear relationship between parameters. , , , is the corresponding adjustment coefficient. This formula is a form of linear combination that combines the linear weights of multiple geotechnical parameters with correction functions to quantify the comprehensive value of the land characteristics. It is designed to comprehensively evaluate the importance of each parameter in dividing the soil layers.

[0032] Among them, a correction function can be:

[0033] Among them, the , , , , , is the corresponding fitting coefficient. This formula adopts a polynomial form to capture the nonlinear interaction between parameters and improve the sensitivity and predictive ability of the segmentation threshold function to soil layer changes.

[0034] a_1, a_2, a_3, a_4: quadratic coefficients corresponding to each parameter, reflecting the impact of a single change of each parameter on the threshold function; a_5, a_6: interaction coefficients, reflecting the importance of the linkage effect between geotechnical parameters and explaining the comprehensive influence of soil characteristics in some cases.

[0035] Among them, another correction function can be: Among them, the , , , is the corresponding weight coefficient, reflecting the importance of the corresponding parameter in the overall segmentation threshold. , , , is the corresponding exponential coefficient, which determines the acceleration effect of parameter changes, especially when the parameter reaches a certain critical value, its influence on the segmentation threshold will increase significantly. This formula introduces an exponential function form to present the nonlinear relationship between the parameter and the segmentation threshold, which is particularly suitable for dealing with the uneven influence of geotechnical parameter changes on soil layer division, so as to increase the sensitivity to extreme cases.

[0036] Specifically, a calculation formula for the change in the segmentation threshold function between adjacent sampling points can be:

[0037] Among them, the is the change in the segmentation threshold function between adjacent sampling points, indicating the overall change in the segmentation threshold caused by the change in geotechnical parameters. By analyzing this change, the significance of soil layer changes can be identified, thereby providing a basis for subsequent soil layer division. is the change in soil density, is the change in moisture content, is the change in permeability coefficient, is the change in shear strength.

[0038] This formula is designed to calculate the change in the segmentation threshold function between adjacent sampling points and is based on the partial differential of the segmentation threshold function. By calculating the change in each geotechnical parameter and multiplying it by its sensitivity to the segmentation threshold function, the effect of soil layer characteristics as the parameter changes can be quantified. This method helps to identify the relative size of the impact of each important parameter on soil characteristics during soil layer changes, so that we can determine the changes in soil layers and their critical points, and then provide a basis for the division of soil layers.

[0039] : The change in the segmentation threshold function between adjacent sampling points indicates the overall change in the segmentation threshold caused by the change in geotechnical parameters. By analyzing this change, the significance of soil layer changes can be identified, thereby providing a basis for subsequent soil layer division.

[0040] : The partial derivative of the segmentation threshold function f with respect to soil density theta reflects the sensitivity of soil density changes to the segmentation threshold. If the value of this partial derivative is large, it means that a small change in soil density will cause a significant change in the segmentation threshold, indicating that soil density plays a key role in soil layer division.

[0041] : The partial derivative of the segmentation threshold function f with respect to the moisture content k measures the degree of influence of the change in moisture content on the segmentation threshold. A higher partial derivative indicates that the fluctuation of moisture content may significantly affect the segmentation threshold, and thus its importance cannot be ignored in the analysis of soil layer changes.

[0042] : The partial derivative of the segmentation threshold function f with respect to the permeability coefficient tau represents the effect of changes in the permeability coefficient on the segmentation threshold. This effect is critical, especially when considering water flow and soil permeability, changes in the permeability coefficient may directly affect the stability and bearing capacity of the soil layer.

[0043] : The partial derivative of the segmentation threshold function f with respect to the shear strength E, reflecting the relative influence of the shear strength on the segmentation threshold. Since the shear strength is used to judge the ability of the soil layer to maintain its shape and structure, its change is particularly important for the critical judgment of the soil layer change.

[0044] , , , : Represent the changes in soil density, water content, permeability and shear strength respectively. Their specific values ​​directly affect the comprehensive evaluation of the segmentation threshold, reflecting the importance of the changes in various parameters to the characteristics of the soil layer in actual sampling.

[0045] S204, identifying soil layer change critical points in the sampling points according to the change amount of the segmentation threshold function between the adjacent sampling points, so as to divide the soil layers based on the soil layer change critical points.

[0046] In this method, the critical point of soil layer change can be effectively identified by analyzing the change of the segmentation threshold function between adjacent sampling points. This process is based on comparative analysis of the calculation results of the segmentation threshold function to determine which sampling points show significant differences when the geotechnical parameters change. When the change of a sampling point exceeds the preset threshold, this point is identified as the critical point of soil layer change. The identification of this critical point is crucial to understanding the continuity and variability of the soil layer, and provides a basis for further soil layer division.

[0047] By identifying the critical points of soil layer changes, the boundary of soil layers can be effectively determined, providing a scientific basis for soil layer classification and characteristic analysis. This process not only improves the accuracy of soil layer division, but also helps in subsequent geotechnical engineering decisions, including infrastructure construction, environmental protection, and resource development. In practical applications, accurate judgment of soil layer changes can effectively reduce engineering risks, optimize design solutions, and improve engineering safety and economy.

[0048] Specifically, if the variation of the segmentation threshold function between the adjacent sampling points is greater than a preset threshold, the corresponding sampling point is identified as a critical point of soil layer variation.

[0049] In the claim, the critical point of soil layer change is identified based on the change in the segmentation threshold function between adjacent sampling points. Specifically, the core of the evaluation is to set a preset threshold. When the calculated change Delta P exceeds the preset value, the corresponding sampling point is identified as the critical point of soil layer change. This step is an important link in judging the change in soil layer characteristics and directly affects the subsequent soil layer division and analysis.

[0050] By setting a reasonable preset threshold, a sensitive response to soil layer changes can be ensured, and sampling points with significant changes can be identified in a timely manner. This not only enhances the accuracy of soil layer classification, but also provides key information for engineering design, soil management, etc. In addition, this step also helps to clearly define the boundaries between different soil layers, providing a reliable basis for subsequent engineering decisions. A reasonable preset threshold can be set based on past experience or statistical analysis results. For example, a threshold value of change suitable for the area can be determined by analyzing historical data. The calculated change is compared with the preset threshold, and the sampling points whose change exceeds the threshold are identified and marked as critical points of soil layer change.

[0051] Specifically, at the identified critical points of soil layer change, corresponding rows in the multidimensional parameter matrix are marked to achieve soil layer division.

[0052] In this step, based on the identified critical points of soil layer changes, the corresponding rows in the multidimensional parameter matrix are marked to achieve soil layer division. This step ensures that the changing position of the soil layer and the characteristics of each layer can be clearly seen in the visualization and analysis of the data, thus providing an important basis for the practical application of the soil layer. By marking the relevant rows in the multidimensional parameter matrix at the critical points of change, the distribution of different soil layers can be intuitively displayed, providing clear guidance and reference for subsequent engineering design, construction plans and soil improvement measures. This process not only enhances the readability of the data, but also improves the efficiency and accuracy of subsequent operations to a certain extent.

[0053] Under the indication of the identified critical point of soil layer change, the corresponding sampling point can be selected and its row in the multidimensional parameter matrix can be marked. For example, the soil layer type corresponding to each sampling point can be identified by adding a column of "soil layer mark". The marked multidimensional parameter matrix is ​​saved in a database or file for subsequent analysis and reference. Data visualization tools such as GIS (geographic information system) can also be used to display the marked data in space, making the distribution of soil layer changes more intuitive and easy to understand. Based on the marking results, a specific engineering implementation plan is formulated, such as determining the burial depth of the foundation project and selecting appropriate soil improvement measures.

[0054] It can be seen that multiple geotechnical parameters of the target soil layer are collected; the collected geotechnical parameters are normalized, and the processed normalized parameter set is constructed into a multidimensional parameter matrix, wherein each row in the multidimensional parameter matrix represents a parameter set of a sampling point, and each column represents a specific parameter; a segmentation threshold function for dividing the standard soil layer is determined, and for the sampling points in the multidimensional parameter matrix, the change amount of the segmentation threshold function between adjacent sampling points is calculated; according to the change amount of the segmentation threshold function between the adjacent sampling points, the critical point of soil layer change in the sampling point is identified, so as to divide the soil layer based on the critical point of stratum change, so as to collect and normalize multiple geotechnical parameters of the target soil layer, and construct a multidimensional parameter matrix, and use a scientific segmentation threshold function to identify the critical point of soil layer change, so as to achieve objective and systematic soil layer division, and improve the accuracy and efficiency of soil layer division.
