Description

Technical Field

[0001] The present invention relates to the technical field of vibro-impact encryption, and specifically designs a method, a device and a medium for analyzing the inclination of gravel piles based on sensor distribution. Background Art

[0002] Currently, during vibroflotation simulation tests, multiple monitoring points are set up around the vibroflotation holes to analyze the effects on the shape of the gravel piles formed during vibroflotation. Sensors are placed at these points to measure the pressure generated during the vibroflotation process. However, vibroflotation simulation tests are limited, as soil is generally used to simulate the strata, which results in a lack of diversity in the ground properties of the strata. In actual vibroflotation, not only are strata divided into different layers due to varying ground properties, but the ground properties within each layer are not necessarily the same. Consequently, the excitation force generated by the vibroflotation device on different ground properties will also vary, causing the gravel piles formed by vibroflotation to tilt between the two layers. Summary of the Invention

[0003] The purpose of the present invention is to provide a method, device and medium for analyzing the inclination of gravel piles based on sensor distribution. The land properties of different strata and different areas are analyzed through sensor distribution, thereby analyzing whether the shape of the gravel piles formed by vibration compaction and densification is tilted. Combined with the actual stratum conditions, the accuracy of the analysis of the gravel pile shape can be improved.

[0004] In order to solve the above technical problems, the present invention adopts the following solutions:

[0005] A method for analyzing the inclination of gravel piles based on sensor distribution includes: a first pile hole to be formed and a second pile hole to be formed are set in the same foundation; in the vertical direction, the foundation is divided into multiple strata at preset vibration retention depths; and multiple identical earth pressure sensors are set in each stratum. In the horizontal direction, the multiple earth pressure sensors are set at equal intervals on a connecting measurement line between the centers of the first pile hole to be formed and the second pile hole to be formed;

[0006] The method comprises the following steps:

[0007] S1. Collecting data during the vibro-impact densification process: While the vibro-impact device is performing vibro-impact densification on the first and second pile holes to be formed at the same vibro-impact setting value, obtain the pressure vector of each earth pressure sensor and mark and record the pressure vector with the coordinate point of the earth pressure sensor;

[0008] S2. Data grouping preprocessing: Packing the pressure vectors of the earth pressure sensors located in the same stratum into a pressure vector group according to the coordinate points of the earth pressure sensors, and connecting the pressure vectors in the same direction in the pressure vector group into a pressure vector chain according to the direction of the pressure vectors;

[0009] S3. Same-layer data analysis: Obtain the regional change values ​​corresponding to the earth pressure sensor and the pressure vector chain. Perform symmetrical cross-comparisons on the pressure vector chains in different directions based on the coordinates of the earth pressure sensor. Determine in turn whether the earth pressure sensor near the first or second pending pile hole meets the large pressure fluctuation condition. If so, mark the current earth pressure sensor as the sensor to be tested.

[0010] S4. Analysis of upper and lower layer data: The current stratum is obtained based on the coordinate point of the sensor to be detected, and it is determined whether the pressure inclination change condition is met between the sensor to be detected and the sensor to be detected in the next stratum to be detected in the current stratum. If so, it is marked that the gravel pile formed in the first pile hole to be formed or the second pile hole to be formed close to the sensor to be detected in the current stratum has tilted in the current stratum.

[0011] Furthermore, the vibration setting values ​​include vibration depth, vibration duration, vibration current, and single gravel addition amount.

[0012] Furthermore, the pressure vector is a pressure variation with a direction. The pressure variation is the maximum value between the data collected by the earth pressure sensor before the vibro-densification and the data collected during the vibro-densification process. The pressure variation is then directionally marked to obtain the pressure vector.

[0013] Specifically, when the pressure change of the current earth pressure sensor is obtained during the process of the vibrator vibrating and densifying the first pile hole to be formed, the direction of the pressure change from the first pile hole to be formed to the second pile hole to be formed is marked to form a pressure vector;

[0014] When the pressure change of the current soil pressure sensor is obtained during the process of the vibrator vibrating and densifying the second pile hole to be formed, the direction of the pressure change from the second pile hole to be formed to the first pile hole to be formed is marked to form a pressure vector.

[0015] Furthermore, the pressure vector group includes two pressure vector chains with opposite directions, one pressure vector chain is composed of pressure vectors with directions from the first pile hole to be formed to the second pile hole to be formed connected in sequence, and the other pressure vector chain is composed of pressure vectors with directions from the second pile hole to be formed to the first pile hole to be formed connected in sequence.

[0016] Furthermore, the step S3 specifically includes the following steps:

[0017] S31: performing central average calculation on two pressure vector chains in opposite directions in the pressure vector group based on the coordinate position of the earth pressure sensor to obtain the central average located at the center of the pressure vector chain, and performing a subtraction between the central average and the value of the pressure vector to obtain the regional change value corresponding to the earth pressure sensor and the pressure vector chain;

[0018] S32: On two pressure vector chains in opposite directions, with the central average value as the center, compare the change values ​​of two symmetrical and intersecting areas on both sides of the central average value. According to the comparison results, determine in turn whether the earth pressure sensor close to the first pile hole to be formed or the second pile hole to be formed meets the large pressure fluctuation condition. If so, mark the current earth pressure sensor as the sensor to be detected.

[0019] Furthermore, in S31, the process of calculating the central average value is:

[0020] Find the pressure vector at the center of two pressure vector chains with opposite directions, calculate the average of the values ​​of the two pressure vectors, and use it as the central average.

[0021] Furthermore, in S3, the condition for large pressure fluctuation is that two regional change values ​​of the earth pressure sensor obtained according to the comparison result are both greater than corresponding regional change values.

[0022] Furthermore, in S4, the pressure inclination change condition is:

[0023] The coordinate point of the sensor to be detected in the current stratum is close to the first pile hole to be formed. At this time, if the coordinate point of the sensor to be detected in the stratum next to the current stratum is close to the second pile hole to be formed, it is determined that the sensor to be detected in the stratum next to the current stratum meets the pressure inclination change condition;

[0024] The coordinate point of the sensor to be detected in the current formation is close to the second pile hole to be formed. At this time, if the coordinate point of the sensor to be detected in the next formation of the current formation is close to the first pile hole to be formed, it is determined that the sensor to be detected in the next formation of the current formation meets the pressure inclination change condition.

[0025] A device for analyzing the inclination of gravel piles based on sensor distribution, comprising:

[0026] a memory for non-transitory storage of computer-readable instructions;

[0027] The processor is configured to execute the computer-readable instructions, wherein the computer-readable instructions, when executed by the processor, implement the method for analyzing the inclination of gravel piles based on sensor distribution.

[0028] A non-transitory computer-readable storage medium stores computer-readable instructions, wherein the non-transitory computer-readable storage medium stores computer-readable instructions, and when the computer-readable instructions are executed by a processor, the method for analyzing the inclination of gravel piles based on sensor distribution is implemented.

[0029] Beneficial effects of the present invention:

[0030] The present invention provides a method, device, and medium for analyzing the inclination of gravel piles based on sensor distribution. The method primarily considers the complexities of actual strata. Multiple sensors are evenly distributed between two vibro-drilled holes, with the sensors being linearly distributed on both the horizontal and vertical planes. This linearly uniform distribution of sensors allows analysis not only of the soil properties within the same stratum but also of the areas between them, making the present invention applicable to actual vibro-drilling processes. Furthermore, by analyzing different strata and different areas, it is possible to quickly and accurately determine whether the shape of the gravel pile formed by vibro-drilling is tilted, thereby improving the accuracy of the analysis of the gravel pile shape.

[0043] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments:

[0045] Example 1

[0046] In this embodiment, to analyze the soil properties of different strata and regions based on actual ground conditions, sensors are distributed to determine whether the vibro-insertion-formed gravel piles exhibit tilt. In this embodiment, the sensors are earth pressure sensors, which utilize the contact area between the soil and the sensor and the soil's elastic modulus to convert soil pressure into an electrical signal for output.

[0047] There are two identical first and second pile holes in the current foundation. Identical means that the first and second pile holes have the same parameters as each other, such as depth and diameter. Figure 1 As shown, in the vertical direction, the foundation can be divided into multiple layers at a preset vibration retention depth or into multiple layers according to the actual land properties, including the first layer, the second layer, and the third layer. Then, the earth pressure sensors located on different layers can be seen on the vertical plane. Figure 1In the figure, soil pressure sensors are represented by square marks, so that the soil pressure sensors on different strata are distributed in an array. Based on the array distribution, each soil pressure sensor can be labeled. Specifically, the soil pressure sensors on the first layer are labeled R11, R12, and R13 from left to right, the soil pressure sensors on the second layer are labeled R21, R22, and R23 from left to right, and the soil pressure sensors on the third layer are labeled R31, R32, and R33 from left to right.

[0048] In the horizontal direction, multiple earth pressure sensors are arranged at the same interval on the connecting survey line between the centers of the first pile hole to be formed and the second pile hole to be formed. Then, the earth pressure sensors located on one stratum can be seen on the horizontal plane. The earth pressure sensors on one stratum are linearly distributed. Based on the distribution of the earth pressure sensors, a coordinate system can be made to map all the earth pressure sensors on the coordinate system. The coordinate points (xi, yj) of the earth pressure sensors, i=1,2,3,…, j=1,2,3,…, are used to reflect the positional relationship of the earth pressure sensors located on the same horizontal plane through xi, such as Figure 2 As shown, in the horizontal direction, soil pressure sensors (x1, y1), soil pressure sensors (x2, y2) and soil pressure sensors (x3, y3) are arranged between the first pile hole to be formed and the second pile hole to be formed. It can be seen that each soil pressure sensor is closer to the first pile hole to be formed or the second pile hole to be formed; yj is used to reflect the positional relationship of soil pressure sensors located on different strata, and it can be seen that the soil pressure sensor is located in the upper or lower layer of the current stratum. The surrounding positional relationship of the soil pressure sensor can be judged through the coordinate point position.

[0049] When the foundation is vibrated and densified according to the vibrator, a vibration densification is performed in a stratum so that the pressure value detected by the sensor can avoid being affected by other factors. The pressure value is only detected once during the vibration densification process. In addition, the vibrator vibrates and densifies the first pile hole and the second pile hole with the same vibration setting value. The vibration setting value includes the vibration depth, vibration time, vibration current, and the amount of gravel added in a single time. The purpose is to reduce the influence of other factors on the pressure value detected by the sensor, so that the pressure value detected by the sensor can reflect the nature of the land around the sensor. For example, when the same exciting force is applied to the same sensor, if the pressure change detected by the current sensor is large, it can indicate that the nature of the land around the current sensor is loose; if the pressure change detected by the current sensor is small, it can indicate that the nature of the land around the current sensor is hard.

[0050] When the vibrator is vibrating and densifying the first unformed pile hole in the current stratum, the vibrator will apply an exciting force from the first unformed pile hole to the second unformed pile hole. At the same time, the pressure sensors located in the current stratum will be subjected to the pressure generated by the exciting force in sequence, that is, the pressure sensors from the soil pressure sensor close to the first unformed pile hole to the soil pressure sensor close to the second unformed pile hole will be subjected to the pressure generated by the exciting force in sequence. Therefore, the pressure change value generated by the current vibratory densification can be detected by the soil pressure sensor, and the pressure change amount is then marked with the direction of the exciting force applied from the first unformed pile hole to the second unformed pile hole to obtain a pressure vector. Then Later, when the vibrator is vibrating and infilling the second unfinished pile hole in the current stratum, it will apply an excitation force from the second unfinished pile hole to the first unfinished pile hole. Simultaneously, the pressure sensors located in the current stratum will be sequentially subjected to the pressure generated by the excitation force, i.e., the pressure sensors from the soil pressure sensor near the second unfinished pile hole to the soil pressure sensor near the first unfinished pile hole will be sequentially subjected to the pressure generated by the excitation force. Thus, the soil pressure sensors can detect the pressure change caused by the current vibratory infilling. The pressure change is then directional-labeled according to the direction of the excitation force applied from the second unfinished pile hole to the first unfinished pile hole, resulting in a pressure vector. It can be seen that the two current pressure vectors are generated by excitation forces in different directions within the same stratum. By analyzing the pressure vectors in different directions within the same stratum, the soil properties of that stratum can be determined.

[0051] Based on the above principle, the present invention provides a method for analyzing the inclination of gravel piles based on sensor distribution, such as Figure 3 As shown, the method includes the following steps:

[0052] S1. Collecting data during the vibro-impact densification process: While the vibro-impact device is performing vibro-impact densification on the first and second pile holes to be formed at the same vibro-impact setting value, obtain the pressure vector of each earth pressure sensor and mark and record the pressure vector with the coordinate point of the earth pressure sensor;

[0053] S2. Data grouping preprocessing: Packing the pressure vectors of the earth pressure sensors located in the same stratum into a pressure vector group according to the coordinate points of the earth pressure sensors, and connecting the pressure vectors in the same direction in the pressure vector group into a pressure vector chain according to the direction of the pressure vectors;

[0054] S3. Same-layer data analysis: Obtain the regional change values ​​corresponding to the earth pressure sensor and the pressure vector chain. Perform symmetrical cross-comparisons on the pressure vector chains in different directions based on the coordinates of the earth pressure sensor. Determine in turn whether the earth pressure sensor near the first or second pending pile hole meets the large pressure fluctuation condition. If so, mark the current earth pressure sensor as the sensor to be tested.

[0055] The S3 specifically includes the following steps:

[0056] S31: performing central average calculation on two pressure vector chains in opposite directions in the pressure vector group based on the coordinate position of the earth pressure sensor to obtain the central average located at the center of the pressure vector chain, and performing a subtraction between the central average and the value of the pressure vector to obtain the regional change value corresponding to the earth pressure sensor and the pressure vector chain;

[0057] S32: On two pressure vector chains in opposite directions, taking the central average as the center, compare the change values ​​of two symmetrical and intersecting regions on both sides of the central average. Based on the comparison results, determine in turn whether the earth pressure sensor close to the first pile hole to be formed or the second pile hole to be formed meets the large pressure fluctuation condition. If so, mark the current earth pressure sensor as a sensor to be tested.

[0058] S4. Analysis of upper and lower layer data: The current stratum is obtained based on the coordinate point of the sensor to be detected, and it is determined whether the pressure inclination change condition is met between the sensor to be detected and the sensor to be detected in the next stratum to be detected in the current stratum. If so, it is marked that the gravel pile formed in the first pile hole to be formed or the second pile hole to be formed close to the sensor to be detected in the current stratum has tilted in the current stratum.

[0059] By using the above-mentioned gravel pile inclination analysis method, it is possible to analyze whether the gravel pile formed in the first to-be-formed pile hole or the second to-be-formed pile hole is inclined based on the distribution of soil pressure sensors.

[0060] Specifically, when a vibrator with the same vibration setting value is used to vibrate and densify the current stratum in the first and second pile holes to be formed, respectively, through the soil pressure sensors R11, R12, and R13, one soil pressure sensor corresponds to two pressure changes. Pressure change 1 is generated by the vibrator vibrating and densifying the current stratum in the first pile hole to be formed, and pressure change 2 is generated by the vibrator vibrating and densifying the current stratum in the second pile hole to be formed, as shown in Table 1. The pressure change is the maximum value between the data collected by the soil pressure sensor before vibrating and densifying and the data collected during the vibrating and densifying process.

[0061] Table 1 Pressure change table

[0062] R11 R12 R13 Pressure change 1 100 80 50 Pressure change 2 60 86 110

[0063] According to Table 1, when the vibrator generates the same exciting force on the same stratum, the pressure change detected by the earth pressure sensor is different according to the different vector directions of the exciting force. Because the exciting forces in different vector directions pass through areas with different land properties, the land properties around the earth pressure sensors R11, R12, and R13, that is, the land properties on the left and right sides of the earth pressure sensors, can be reflected by the pressure change. In the same vector direction, the pressure change detected by the previous earth pressure sensor is greater than that detected by the next earth pressure sensor. The pressure change amount can also reflect the land properties between the soil pressure sensor near the first pile hole to be formed and the first pile hole to be formed, and the land properties between the soil pressure sensor near the second pile hole to be formed and the second pile hole to be formed. If the land properties here are relatively loose, when the vibrator is performing the vibration densification process, the excitation force generated by the vibrator on the first pile hole to be formed or the second pile hole to be formed will generate greater pressure on the soil on both sides, thereby causing the gravel pile formed by vibration densification to tilt, that is, the gravel pile expands to both sides of the first pile hole to be formed or the second pile hole to be formed.

[0064] In order to improve the accuracy of the analysis of whether the shape of the gravel pile formed by vibration compaction is tilted, because the soil pressure sensor R11 and the soil pressure sensor R13 are respectively closer to the first pile hole to be formed and the second pile hole to be formed, when the vibrator is used to perform vibration compaction in the first pile hole to be formed, the soil pressure sensor R11 can more easily detect a larger pressure change; when the vibrator is used to perform vibration compaction in the second pile hole to be formed, the soil pressure sensor R13 can also more easily detect a larger pressure change.

[0065] Therefore, the present invention considers analyzing the pressure changes caused by exciting forces of different vector directions in the same stratum. First, it is necessary to mark the direction of the soil pressure changes according to the different vector directions of the exciting force to obtain the pressure vector. The value of the pressure vector is the corresponding pressure change, and the direction of the pressure vector is the vector direction of the corresponding exciting force.

[0066] In another embodiment, when the pressure change of the current soil pressure sensor is obtained during the process of the vibrator vibrating and filling the first pile hole to be formed, the pressure change is marked in the direction from the first pile hole to be formed to the second pile hole to be formed to form a pressure vector; when the pressure change of the current soil pressure sensor is obtained during the process of the vibrator vibrating and filling the second pile hole to be formed, the pressure change is marked in the direction from the second pile hole to be formed to the first pile hole to be formed to form a pressure vector.

[0067] Then, the pressure vectors of the earth pressure sensors located in the same stratum are packaged into a pressure vector group according to the coordinate points of the earth pressure sensors, and the pressure vectors in the same direction in the pressure vector group are connected into a pressure vector chain according to the direction of the pressure vector.

[0068] In another embodiment, the pressure vector group includes two pressure vector chains with opposite directions, one pressure vector chain is composed of pressure vectors with directions from the first pile hole to the second pile hole to be formed connected in sequence, and the other pressure vector chain is composed of pressure vectors with directions from the second pile hole to the first pile hole to be formed connected in sequence.

[0069] Then, the direction of the pressure change in Table 1 is marked to form a pressure vector, and then two pressure vector chains with opposite directions are formed according to the direction vector, namely pressure vector chain 1 and pressure vector chain 2, as shown in the following example: Figure 4 As shown, it can be seen that the pressure vectors in pressure vector chain 1 and pressure vector chain 2 can be mapped one-to-one based on the earth pressure sensor, respectively representing the pressure exerted on the earth pressure sensor under the exciting force in different directions.

[0070] Then, the center average value is calculated on two pressure vector chains in opposite directions in the pressure vector group according to the coordinate point of the earth pressure sensor to obtain the center average value located at the center of the pressure vector chain.

[0071] The process of calculating the central mean is:

[0072] Find the pressure vector at the center of two pressure vector chains with opposite directions, calculate the average of the values ​​of the two pressure vectors, and use it as the central average.

[0073] like Figure 4 As shown in Table 1, earth pressure sensors R11, R12, and R13 are installed between the first to-be-formed pile hole and the second to-be-formed pile hole. The pressure changes of the earth pressure sensors R11, R12, and R13 are shown in Table 1. Then, pressure vector chains 1 and 2 are formed in different directions between the first to-be-formed pile hole and the second to-be-formed pile hole. The value of the pressure vector at the center of pressure vector chain 1 is 80, and the value of the pressure vector at the center of pressure vector chain 1 is 86. The central average value is 83. Then, the central average value is subtracted from the value of the pressure vector to obtain the regional change value corresponding to the earth pressure sensor and the pressure vector chain, as shown in Table 1. Figure 5 As shown, the regional change value of the earth pressure sensor R11 corresponding to the pressure vector chain 1 is 17, and the regional change value corresponding to the pressure vector chain 1 is 23; the regional change value of the earth pressure sensor R13 corresponding to the pressure vector chain 1 is 33, and the regional change value corresponding to the pressure vector chain 1 is 27.

[0074] Then, on the pressure vector chain 1 and the pressure vector chain 2, with the central average value 83 as the center, the change values ​​of the two regions located on both sides of the central average value and symmetrical and intersecting are compared, as shown in FIG. Figure 6As shown, when the regional change value is 17 and the regional change value is 27, the regional change value 27 is larger; when the regional change value is 23 and the regional change value is 33, the regional change value 33 is larger. It can be seen that when the vibrator vibrates and densifies the first pile hole to be formed and the second pile hole to be formed, if the excitation force generated to the outer soil is the same, and the regional change value is 17 and the regional change value is 27, the regional change value 27 is larger, which means that when the soil pressure sensor R11 and the soil pressure sensor R13 are the first pressure sensors to be exposed to the excitation force, the soil pressure sensor R13 is subjected to a larger pressure, which means that the soil between the soil pressure sensor R13 and the second pile hole to be formed is relatively loose; when the vibrator vibrates and densifies the first pile hole to be formed and the second pile hole to be formed, if the excitation force generated to the outer soil is the same, and the regional change value is 2 3 Compared with the regional change value of 33, the regional change value 33 is larger, which means that when the earth pressure sensor R11 and the earth pressure sensor R13 are the last pressure sensors to contact the exciting force, the earth pressure sensor R13 is still subjected to a large pressure, which means that the land property between the earth pressure sensor R13 and the earth pressure sensor R12 is relatively loose, and the land property between the earth pressure sensor R13 and the second pile hole to be formed is also relatively loose. It can be determined that the land property around the earth pressure sensor R13 itself is loose. At this time, the earth pressure sensor R13 meets the large pressure fluctuation condition, and the earth pressure sensor R13 is marked as the sensor to be detected.

[0075] Then, the vibrator performs vibration densification on the second layer of stratum and lifts the vibrator upward, i.e., performs vibration densification for the second time in the next stratum of the current stratum in the first and second holes to be piled. Through the above steps, the soil pressure sensors located in the second stratum can be analyzed in the same layer to determine whether the soil pressure sensors close to the first and second holes to be piled meet the large pressure fluctuation condition. If so, the soil pressure sensors are marked as sensors to be detected in the second stratum. When there are sensors to be detected in the second stratum, it is determined whether the pressure inclination change condition is met between the sensors to be detected and the sensors to be detected in the second stratum. If so, it is marked that the gravel piles formed in the first or second holes to be piled close to the sensors to be detected in the current stratum are tilted in the current stratum.

[0076] In another embodiment, the pressure gradient change condition is:

[0077] The coordinate point of the sensor to be detected in the current stratum is close to the first pile hole to be formed. At this time, if the coordinate point of the sensor to be detected in the stratum next to the current stratum is close to the second pile hole to be formed, it is determined that the sensor to be detected in the stratum next to the current stratum meets the pressure inclination change condition;

[0078] The coordinate point of the sensor to be detected in the current formation is close to the second pile hole to be formed. At this time, if the coordinate point of the sensor to be detected in the next formation of the current formation is close to the first pile hole to be formed, it is determined that the sensor to be detected in the next formation of the current formation meets the pressure inclination change condition.

[0079] like Figure 7 As shown, the earth pressure sensor R13 in the current stratum is close to the second pile hole to be formed. At this time, the earth pressure sensor R21 in the second stratum is the sensor to be detected in the second stratum. Moreover, it can be seen that the earth pressure sensor R21 is close to the first pile hole to be formed. Figure 7 The square mark representing the earth pressure sensor R21 is filled with color, indicating that in the second stratum, the soil near the first pile hole to be formed is loose, while the soil near the second pile hole to be formed is hard, which is opposite to the soil condition of the current stratum. Therefore, it can be marked that the gravel pile formed in the first pile hole to be formed or the second pile hole to be formed near the sensor to be detected in the current stratum is tilted in the current stratum. Figure 7 The square mark representing the earth pressure sensor R13 is filled with color, and the curve next to the earth pressure sensor R13 indicates that the gravel pile formed near the second pile hole to be formed is tilted in the current stratum.

Collecting data during the vibro-impact densification process: While the vibro-impact device is performing vibro-impact densification on the first and second pile holes to be formed at the same vibro-impact setting value, obtain the pressure vector of each earth pressure sensor and mark and record the pressure vector with the coordinate point of the earth pressure sensor; S2. Data grouping preprocessing: Packing the pressure vectors of the earth pressure sensors located in the same stratum into a pressure vector group according to the coordinate points of the earth pressure sensors, and connecting the pressure vectors in the same direction in the pressure vector group into a pressure vector chain according to the direction of the pressure vectors; S3. Same-layer data analysis: Obtain the regional change values ​​corresponding to the earth pressure sensor and the pressure vector chain. Perform symmetrical cross-comparisons on the pressure vector chains in different directions based on the coordinates of the earth pressure sensor. Determine in turn whether the earth pressure sensor near the first or second pending pile hole meets the large pressure fluctuation condition. If so, mark the current earth pressure sensor as the sensor to be tested. The S3 specifically includes the following steps: S31: performing central average calculation on two pressure vector chains in opposite directions in the pressure vector group based on the coordinate position of the earth pressure sensor to obtain a central average value located at the center of the pressure vector chain, and performing a subtraction between the central average value and the value of the pressure vector to obtain a regional change value corresponding to the earth pressure sensor and the pressure vector chain; wherein the process of calculating the central average value is as follows: finding the pressure vector located at the center of the two pressure vector chains in opposite directions, calculating the average value of the two pressure vectors, and taking the average value as the central average value; S32: On two pressure vector chains in opposite directions, with the central average value as the center, two regional change values ​​located symmetrically and intersecting on both sides of the central average value are compared. Based on the comparison results, it is determined in turn whether the earth pressure sensor close to the first pile hole to be formed or the second pile hole to be formed meets the large pressure fluctuation condition. If so, the current earth pressure sensor is marked as a sensor to be tested; wherein the large pressure fluctuation condition is that the two regional change values ​​of the earth pressure sensor obtained according to the comparison result are both greater than the corresponding regional change value; S4. Analysis of upper and lower layer data: The current stratum is obtained based on the coordinate point of the sensor to be detected, and a determination is made as to whether a pressure tilt change condition is satisfied between the sensor to be detected and a sensor to be detected in the stratum below the current stratum. If so, a mark is given as indicating that a gravel pile formed in the first or second pile hole to be formed, which is close to the sensor to be detected in the current stratum, has tilted in the current stratum. Wherein, the pressure inclination change condition is: The coordinate point of the sensor to be detected in the current stratum is close to the first pile hole to be formed. At this time, if the coordinate point of the sensor to be detected in the stratum next to the current stratum is close to the second pile hole to be formed, it is determined that the sensor to be detected in the stratum next to the current stratum meets the pressure inclination change condition; The coordinate point of the sensor to be detected in the current formation is close to the second pile hole to be formed. At this time, if the coordinate point of the sensor to be detected in the next formation of the current formation is close to the first pile hole to be formed, it is determined that the sensor to be detected in the next formation of the current formation meets the pressure inclination change condition.
