Description

Technical Field

[0001] The present invention relates to the technical field of vibroflotation densification, and particularly to a method, device and medium for analyzing the inclination of gravel pile construction based on sensor distribution. Background Art

[0002] At present, during the vibroflotation densification simulation test, in order to analyze the influence on the shape of the gravel pile formed by vibroflotation densification, multiple monitoring points are set around the vibroflotation hole, sensors are placed at the monitoring points, and the pressure generated during the vibroflotation densification process can be obtained through the sensors. However, the vibroflotation densification simulation test is relatively limited, and soil is generally used to simulate the formation, so that the soil properties of the formation do not have diversity. In the actual process of vibroflotation densification, the formation is not only divided into different layers due to different soil properties, but the soil properties are not necessarily the same in different regions of each layer. The exciting force generated by the vibroflot when performing vibroflotation densification on different soil properties is also different, resulting in the gravel pile formed by vibroflotation densification showing an inclined phenomenon in 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 pile construction based on sensor distribution, which analyzes the soil properties of different formations and different regions through sensor distribution, so as to analyze whether the shape of the gravel pile formed by vibroflotation densification is inclined. Combining the actual formation situation, the accuracy of analyzing the shape of the gravel pile can be improved.

[0004] To solve the above technical problems, the present invention adopts the following solutions: A method for analyzing the inclination of gravel pile construction based on sensor distribution includes the same first to-be-formed pile hole and second to-be-formed pile hole arranged in the foundation; in the vertical direction, the foundation is divided into multiple formations with a preset vibration-retaining depth; and the same multiple earth pressure sensors are arranged in each formation. In the horizontal direction, the multiple earth pressure sensors are arranged at the same interval on the connecting measurement line between the centers of the first to-be-formed pile hole and the second to-be-formed pile hole. The method includes the following steps: S1. Collect data during the vibroflotation densification process: During the process of the vibroflot performing vibroflotation densification on the first to-be-formed pile hole and the second to-be-formed pile hole respectively with the same vibroflotation setting value, the pressure vector of each earth pressure sensor is obtained respectively, and the pressure vector is marked and recorded with the coordinate position of the earth pressure sensor. S2. Data grouping and preprocessing: According to the coordinate positions of the earth pressure sensors, the pressure vectors of the earth pressure sensors located in the same formation are packed into a pressure vector group, 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 vectors. S3. Data analysis of the same layer: Obtain the regional change value corresponding to the soil pressure sensor and the pressure vector chain. Conduct symmetric cross-comparisons on the pressure vector chains in different directions based on the coordinate points of the soil pressure sensor, and sequentially determine whether the soil pressure sensors near the first or second pile hole to be formed meet the condition of large pressure fluctuations. If so, mark the current soil pressure sensor as a sensor to be detected; S4. Data analysis of the upper and lower layers: Obtain the current formation based on the coordinate points of the sensor to be detected, and determine whether the condition of pressure inclination change is met between the sensor to be detected and the sensors to be detected in the next formation located in the current formation. If so, mark that the gravel pile formed in the first or second pile hole to be formed near the sensor to be detected in the current formation is inclined in the current formation.

[0005] Furthermore, the vibroflotation setting values include the retention depth, retention time, retention current, and single gravel addition amount.

[0006] Furthermore, the pressure vector is the pressure change amount with a direction. The pressure change amount is the maximum value between the data collected by the soil pressure sensor before vibroflotation densification and the data collected during the vibroflotation densification process. Then, mark the direction of the pressure change amount to obtain the pressure vector; Specifically, when obtaining the pressure change amount of the current soil pressure sensor during the vibroflotation densification of the first pile hole to be formed by the vibroflot, mark the direction of the pressure change amount from the first pile hole to the second pile hole to form a pressure vector; When obtaining the pressure change amount of the current soil pressure sensor during the vibroflotation densification of the second pile hole to be formed by the vibroflot, mark the direction of the pressure change amount from the second pile hole to the first pile hole to form a pressure vector.

[0007] Furthermore, the pressure vector group includes two pressure vector chains in opposite directions. One pressure vector chain is composed of sequentially connected pressure vectors with the direction from the first pile hole to the second pile hole, and the other pressure vector chain is composed of sequentially connected pressure vectors with the direction from the second pile hole to the first pile hole.

[0008] Furthermore, the specific steps in S3 are as follows: S31: Calculate the central average value on the two pressure vector chains in opposite directions in the pressure vector group based on the coordinate points of the soil pressure sensor, obtain the central average value located at the center of the pressure vector chain, and subtract the value of the pressure vector from the central average value to obtain the regional change value corresponding to the soil pressure sensor and the pressure vector chain; S32: On two pressure vector chains in opposite directions, with the central average value as the center, compare the change values of two symmetric and intersecting regions located on both sides of the central average value. According to the comparison result, sequentially determine whether the earth pressure sensors near the first pile to be formed or the second pile to be formed meet the condition of large pressure fluctuation. If so, mark the current earth pressure sensor as the sensor to be detected.

[0009] Further, in S31, the process of calculating the central average value is as follows: Find the pressure vectors at the center on two pressure vector chains in opposite directions, calculate the average value of the values of the two pressure vectors, and use it as the central average value.

[0010] Further, in S3, the condition of large pressure fluctuation is that according to the comparison result, the change values of the two regions of the earth pressure sensor are both greater than the corresponding region change values.

[0011] Further, in S4, the condition of pressure inclination change is as follows: The coordinate position of the sensor to be detected in the current formation is close to the first pile to be formed. At this time, if the coordinate position of the sensor to be detected in the next formation of the current formation is close to the second pile to be formed, it is determined that the sensor to be detected in the next formation of the current formation meets the condition of pressure inclination change; The coordinate position of the sensor to be detected in the current formation is close to the second pile to be formed. At this time, if the coordinate position of the sensor to be detected in the next formation of the current formation is close to the first pile to be formed, it is determined that the sensor to be detected in the next formation of the current formation meets the condition of pressure inclination change.

[0012] A gravel pile pile-making inclination analysis device based on sensor distribution includes: A memory for non-transiently storing computer-readable instructions; A processor for running the computer-readable instructions, and when the computer-readable instructions are run by the processor, the gravel pile pile-making inclination analysis method based on sensor distribution is implemented.

[0013] A non-transient computer-readable storage medium, wherein the non-transient computer-readable storage medium stores computer-readable instructions, and when the computer-readable instructions are executed by a processor, the gravel pile pile-making inclination analysis method based on sensor distribution is implemented.

[0014] The beneficial effects of the present invention: The present invention provides a method, device and medium for analyzing the inclination of gravel pile construction based on sensor distribution. The gravel pile construction inclination method mainly considers the complex conditions of the actual formation. A plurality of sensors are evenly distributed between two vibroflotation holes. The sensors are linearly distributed on the same horizontal plane and the same vertical plane. According to the linearly and evenly distributed sensors, not only the soil properties of the same formation can be analyzed, but also the soil properties of the area between the two can be analyzed, enabling the present invention to be applied to the actual vibroflotation densification process. Moreover, through the analysis of different formations and different regions, it is possible to quickly and accurately analyze whether the shape of the gravel pile formed by vibroflotation densification is inclined, improving the accuracy of analyzing the shape of the gravel pile.

[0020] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the authorization specification.

[0021] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments: Embodiment 1 In this embodiment, in order to be able to combine the actual formation conditions and analyze the land properties of different formations and different regions through sensor distribution, thereby analyzing whether the shape of the gravel piles formed by vibroflotation densification is inclined. Among them, in this embodiment, the sensor refers to an earth pressure sensor, and the main principle of the earth pressure sensor is to utilize the contact area between the soil and the sensor and the elastic modulus of the soil to convert the soil pressure into an electrical signal for output.

[0023] There are two identical first to-be-formed pile holes and second to-be-formed pile holes provided in the current foundation. Identical means that the pile hole parameters such as the depth and diameter of the first to-be-formed pile hole and the second to-be-formed pile hole are the same; as Figure 1 shown, in the vertical direction, the foundation can be divided into multiple formations according to a preset vibration retention depth or 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 formations can be seen in the vertical plane. In Figure 1 the earth pressure sensors are represented by square marks, so that the earth pressure sensors on different formations are presented in an array distribution. Based on the array distribution, each earth pressure sensor can be numbered. Specifically, the earth pressure sensors on the first layer are sequentially marked as R11, R12, and R13 from left to right, the earth pressure sensors on the second layer are sequentially marked as R21, R22, and R23 from left to right, and the earth pressure sensors on the third layer are sequentially marked as R31, R32, and R33 from left to right.

[0024] Horizontally, multiple earth pressure sensors are arranged at equal intervals on the connecting line between the centers of the first pile hole to be formed and the second pile hole to be formed. Then, on the horizontal plane, the earth pressure sensors located on one stratum can be seen, and the earth pressure sensors on one stratum show a linear distribution. Based on the distribution of the earth pressure sensors, a coordinate system can be established, and all the earth pressure sensors are mapped onto the coordinate system. Through the coordinate points (xi, yj) of the earth pressure sensors, where i = 1, 2, 3, …, j = 1, 2, 3, …, the position relationship of the earth pressure sensors located on the same horizontal plane is reflected by xi. As Figure 2 shown, horizontally, an earth pressure sensor (x1, y1), an earth pressure sensor (x2, y2), and an earth pressure sensor (x3, y3) are arranged between the first pile hole to be formed and the second pile hole to be formed. It can be seen whether each earth pressure sensor is closer to the first pile hole to be formed or closer to the second pile hole to be formed; the position relationship of the earth pressure sensors located on different strata is reflected by yj. It can be seen whether the earth pressure sensor is located on the upper layer or the lower layer of the current stratum. The surrounding position relationship of the earth pressure sensor can be judged through the coordinate points.

[0025] When the foundation is densified by vibroflotation according to the vibroflot, one-time vibration retention densification is carried out in one stratum, so that the pressure value detected by the sensor can be prevented from being affected by other factors, and only the pressure value during the vibroflotation densification process is detected. Moreover, the vibroflot densifies the first pile hole to be formed and the second pile hole to be formed respectively with the same vibroflotation setting values. The vibroflotation setting values include vibration retention depth, vibration retention duration, vibration retention current, and single-time gravel addition amount. 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 soil properties around the sensor. For example, when the same excitation force is applied to the same sensor, if the detected pressure change amount of the current sensor is large, it can indicate that the soil properties around the current sensor are relatively loose; if the detected pressure change amount of the current sensor is small, it can indicate that the soil properties around the current sensor are relatively hard.

[0026] When the vibroflot vibrates and compacts the first pile hole to be formed in the current formation, the vibroflot applies an exciting force from the first pile hole to be formed to the second pile hole to be formed. At the same time, the pressure sensors located in the current formation will successively receive the pressures generated by the exciting force, that is, the soil pressure sensors from the one close to the first pile hole to be formed to the one close to the second pile hole to be formed will successively receive the pressures generated by the exciting force. Thus, the pressure change value generated by the current vibration compaction can be detected through the soil pressure sensors, and then the direction of the pressure change amount is marked with the direction of applying the exciting force from the first pile hole to be formed to the second pile hole to obtain a pressure vector. Then, when the vibroflot vibrates and compacts the second pile hole to be formed in the current formation, the vibroflot applies an exciting force from the second pile hole to be formed to the first pile hole to be formed. At the same time, the pressure sensors located in the current formation will successively receive the pressures generated by the exciting force, that is, the soil pressure sensors from the one close to the second pile hole to be formed to the one close to the first pile hole to be formed will successively receive the pressures generated by the exciting force. Thus, the pressure change value generated by the current vibration compaction can be detected through the soil pressure sensors, and then the direction of the pressure change amount is marked with the direction of applying the exciting force from the second pile hole to be formed to the first pile hole to be formed to obtain a pressure vector. It can be seen that the current two pressure vectors are generated by the exciting forces in different directions in the same formation. By analyzing the pressure vectors in different directions in the same formation, the soil properties in this formation can be obtained.

[0027] Based on the above principle, the present invention provides a method for analyzing the inclination of gravel pile formation based on sensor distribution, as Figure 3 shown, the method includes the following steps: S1. Collect data during the vibration compaction process: During the process of the vibroflot vibrating and compacting the first pile hole to be formed and the second pile hole to be formed respectively with the same vibration compaction setting value, the pressure vectors of each soil pressure sensor are obtained respectively, and the pressure vectors are marked and recorded with the coordinate positions of the soil pressure sensors. S2. Data grouping and preprocessing: According to the coordinate positions of the soil pressure sensors, the pressure vectors of the soil pressure sensors located in the same formation are packed into a pressure vector group, 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 vectors. S3. Analysis of data in the same layer: Obtain the regional change value corresponding to the soil pressure sensor and the pressure vector chain, and perform symmetric cross-comparison on the pressure vector chains in different directions according to the coordinate positions of the soil pressure sensors, and successively determine whether the soil pressure sensors near the first pile hole to be formed or the second pile hole to be formed meet the condition of large pressure fluctuations. If so, mark the current soil pressure sensor as a sensor to be detected. The specific steps in S3 include the following: S31: Calculate the central average value on two pressure vector chains in opposite directions in the pressure vector group according to the coordinate points of the earth pressure sensor, obtain the central average value located at the center of the pressure vector chain, and subtract the value of the pressure vector from the central average value to obtain the regional change value corresponding to the earth pressure sensor and the pressure vector chain; S32: Centered on the central average value on two pressure vector chains in opposite directions, compare the two regional change values that are symmetric and cross on both sides of the central average value. According to the comparison result, sequentially determine whether the earth pressure sensors near the first to-be-formed pile hole or the second to-be-formed pile hole meet the condition of large pressure fluctuation. If so, mark the current earth pressure sensor as the to-be-detected sensor; S4. Analysis of upper and lower layer data: Obtain the current formation according to the coordinate points of the to-be-detected sensor, and determine whether the condition of pressure inclination change is met between the to-be-detected sensor and the to-be-detected sensor in the next formation located in the current formation. If so, mark that the gravel pile formed in the first to-be-formed pile hole or the second to-be-formed pile hole near the to-be-detected sensor in the current formation is inclined in the current formation.

[0028] Through the above-mentioned analysis method for the inclination of the gravel pile during pile formation, 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 the earth pressure sensors.

[0029] Specifically, when vibroflotators with the same vibroflotation setting values are used to perform vibroflotation densification on the current formation in the first to-be-formed pile hole and the second to-be-formed pile hole respectively, through the earth pressure sensor R11, the earth pressure sensor R12, and the earth pressure sensor R13, one earth pressure sensor corresponds to two pressure change amounts. The pressure change amount 1 is generated by the vibroflotator performing vibroflotation densification on the current formation in the first to-be-formed pile hole, and the pressure change amount 2 is generated by the vibroflotator performing vibroflotation densification on the current formation in the second to-be-formed pile hole, as shown in Table 1. Among them, the pressure change amount is the maximum value between the data collected by the earth pressure sensor before vibroflotation densification and the data collected during the vibroflotation densification process.

[0030] Table 1 Pressure change table R11 R12 R13 Pressure change amount 1 100 80 50 Pressure change amount 2 60 86 110 As can be seen from Table 1, when the vibroflot generates the same exciting force on the same stratum, due to the different vector directions of the exciting force, the pressure change detected by the earth pressure sensor is also different. Because the exciting forces in different vector directions pass through areas with different soil properties, the soil properties around the earth pressure sensors R11, R12, and R13 can be reflected by the pressure change, that is, the soil properties on the left and right sides of the earth pressure sensors. And 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. Moreover, through the pressure change, the soil properties between the earth pressure sensor close to the first pile hole to be formed and the first pile hole to be formed, and the soil properties between the earth pressure sensor close to the second pile hole to be formed and the second pile hole to be formed can also be reflected. When the soil property here is relatively loose, during the vibroflotation densification process, the exciting force generated by the vibroflot on the first pile hole to be formed or the second pile hole to be formed will exert a greater pressure on the soil on both sides, thereby causing the gravel pile formed by vibroflotation densification to tilt, that is, the gravel pile expands to both sides with respect to the first pile hole to be formed or the second pile hole to be formed.

[0031] In order to improve the accuracy of analyzing whether the shape of the gravel pile formed by vibroflotation densification is tilted, because the earth pressure sensors R11 and R13 are relatively close to the first pile hole to be formed and the second pile hole to be formed respectively, when the vibroflot is used for vibroflotation densification in the first pile hole to be formed, the earth pressure sensor R11 is more likely to detect a large pressure change; when the vibroflot is used for vibroflotation densification in the second pile hole to be formed, the earth pressure sensor R13 is also more likely to detect a large pressure change.

[0032] Therefore, the present invention considers analyzing the pressure changes generated by exciting forces in different vector directions in the same stratum. First, it is necessary to mark the direction of the earth pressure change according to the different vector directions of the exciting force to obtain a 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.

[0033] In another embodiment, when obtaining the pressure change of the current earth pressure sensor during the process of the vibroflot performing vibroflotation densification on the first pile hole to be formed, mark the direction of the pressure change from the first pile hole to the second pile hole to form a pressure vector; when obtaining the pressure change of the current earth pressure sensor during the process of the vibroflot performing vibroflotation densification on the second pile hole to be formed, mark the direction of the pressure change from the second pile hole to the first pile hole to form a pressure vector.

[0034] Then, according to the coordinate points of the earth pressure sensors, pack the pressure vectors of the earth pressure sensors in the same stratum into a pressure vector group, and connect the pressure vectors in the same direction in the pressure vector group into a pressure vector chain according to the direction of the pressure vector.

[0035] In another embodiment, the pressure vector group includes two pressure vector chains in opposite directions. One pressure vector chain is composed of pressure vectors sequentially connected in the direction from the first pile-forming hole to the second pile-forming hole, and the other pressure vector chain is composed of pressure vectors sequentially connected in the direction from the second pile-forming hole to the first pile-forming hole.

[0036] Then, direction marking is performed according to the varying pressure amounts in Table 1 to form pressure vectors, and two pressure vector chains in opposite directions are formed according to the direction vectors, namely pressure vector chain 1 and pressure vector chain 2. As Figure 4 shown, it can be seen that the pressure vectors in pressure vector chain 1 and pressure vector chain 2 can be in one-to-one correspondence based on the earth pressure sensors, respectively representing the pressures received by the earth pressure sensors under excitation forces in different directions.

[0037] Then, central average value calculation is performed on the two pressure vector chains in opposite directions in the pressure vector group according to the coordinate positions of the earth pressure sensors to obtain the central average value located at the center of the pressure vector chain.

[0038] The process of the central average value calculation is as follows: Find the pressure vectors located at the center on the two pressure vector chains in opposite directions, calculate the average value of the values of the two pressure vectors, and use it as the central average value.

[0039] As Figure 4 shown, earth pressure sensors R11, R12, and R13 are arranged between the first pile-forming hole and the second pile-forming hole. The pressure change amounts of earth pressure sensors R11, R12, and R13 are shown in Table 1. Then, pressure vector chains 1 and 2 in different directions are formed between the first pile-forming hole and the second pile-forming hole. The value of the pressure vector located at the center of pressure vector chain 1 is 80, and the value of the pressure vector located at the center of pressure vector chain 1 is 86. Then the central average value is 83. Then, the difference is taken between the central average value and the numerical value of the pressure vector to obtain the regional change value corresponding to the earth pressure sensor and the pressure vector chain. As Figure 5 shown, the regional change value corresponding to earth pressure sensor R11 and pressure vector chain 1 is 17, and the regional change value corresponding to pressure vector chain 1 is 23; the regional change value corresponding to earth pressure sensor R13 and pressure vector chain 1 is 33, and the regional change value corresponding to pressure vector chain 1 is 27.

[0040] Then, with the central average value of 83 as the center on pressure vector chain 1 and pressure vector chain 2, compare the two regional change values that are symmetric and cross on both sides of the central average value. As Figure 6As shown, when comparing the regional change value of 17 with the regional change value of 27, the regional change value of 27 is larger; when comparing the regional change value of 23 with the regional change value of 33, the regional change value of 33 is larger. It can be seen that when the vibroflot vibrates and compacts the first pile hole to be formed and the second pile hole to be formed, if the exciting forces generated on the outer soil are the same, and when comparing the regional change value of 17 with the regional change value of 27, the regional change value of 27 is larger, it means that when the earth pressure sensors R11 and R13 are the first pressure sensors to contact the exciting force, the earth pressure sensor R13 receives a greater pressure, indicating that the soil property between the earth pressure sensor R13 and the second pile hole to be formed is relatively loose; when the vibroflot vibrates and compacts the first pile hole to be formed and the second pile hole to be formed, if the exciting forces generated on the outer soil are the same, and when comparing the regional change value of 23 with the regional change value of 33, the regional change value of 33 is larger, it means that when the earth pressure sensors R11 and R13 are the last pressure sensors to contact the exciting force, the earth pressure sensor R13 still receives a greater pressure, indicating that the soil property between the earth pressure sensor R13 and the earth pressure sensor R12 is relatively loose, and the soil property between the earth pressure sensor R13 and the second pile hole to be formed is also relatively loose. Then, it can be determined that the soil property around the earth pressure sensor R13 is loose by itself. At this time, the earth pressure sensor R13 meets the condition of large pressure fluctuation, and the earth pressure sensor R13 is marked as a sensor to be detected.

[0041] Next, the vibroflot vibrates and compacts the second layer of the formation. Lift the vibroflot upward, that is, perform the second vibration compaction in the next formation of the current formation in the first pile hole to be formed and the second pile hole to be formed. Through the above steps, the data analysis of the same layer can be carried out on the earth pressure sensors located in the second layer of the formation to determine whether the earth pressure sensors near the first pile hole to be formed and the second pile hole to be formed meet the condition of large pressure fluctuation. If so, mark the earth pressure sensor as a sensor to be detected in the second layer of the formation. When there are sensors to be detected in the second layer of the formation, determine whether the condition of pressure inclination change is met between the sensors to be detected in the second layer of the formation. If so, mark 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 formation is inclined in the current formation.

[0042] In another embodiment, the condition of pressure inclination change is: The coordinate point of the sensor to be detected in the current formation 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 next formation of the current formation is close to the second pile hole to be formed, it is determined that the sensor to be detected in the next formation of the current formation meets the condition of pressure inclination change; 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 below 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 below the current formation meets the pressure inclination change condition.

[0043] As Figure 7 shown, the earth pressure sensor R13 in the current formation is close to the second pile hole to be formed. At this time, the earth pressure sensor R21 in the second formation is the sensor to be detected in the second formation, and it can be seen that the earth pressure sensor R21 is close to the first pile hole to be formed. In Figure 7 the square mark used to represent the earth pressure sensor R21 is filled with color, indicating that in the second formation, the soil near the first pile hole to be formed is relatively loose, while the soil near the second pile hole to be formed is relatively hard, which is contrary to the soil condition of the current formation. Therefore, it can be marked that the gravel pile formed in the first pile hole to be formed or the second pile hole to which the sensor to be detected in the current formation is close causes inclination in the current formation. In Figure 7 the square mark used to represent the earth pressure sensor R13 is filled with color, and moreover, the curve beside the earth pressure sensor R13 is used to indicate that the gravel pile formed in the second pile hole to be formed causes inclination in the current formation.

[0044] A device for analyzing the inclination of gravel pile construction based on sensor distribution includes: A memory for non-transiently storing computer-readable instructions; A processor for running the computer-readable instructions, and when the computer-readable instructions are run by the processor, the method for analyzing the inclination of gravel pile construction based on sensor distribution as described above is implemented.

[0046] As mentioned above, it is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. According to the technical essence of the present invention, within the spirit and principle of the present invention, any simple modification, equivalent replacement, and improvement made to the above embodiments still fall within the protection scope of the technical solution of the present invention.
