[0096] In order to enable a more complete understanding of the above-mentioned objects, features and advantages of the present disclosure, the schemes of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0097] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only some of the embodiments of the present disclosure, not all the embodiments.

[0098] SAA deformation monitoring is currently mainly used for building structure stability monitoring, tailings dam stability monitoring and landslide monitoring. The deepest SAA depth displacement analysis known in China is 136 meters, which is applied to the landslide monitoring of Huangdeng Dayun Overseas Chinese Hydropower Station in Yunnan. The deepest depth known abroad is about 150 meters, which is applied to the research of Zelazny Most tailings dam in Poland. There is no known case of more than 200 meters deep. Moreover, the slope deformation SAA analysis technology is mainly applied to the slope with obvious deformation, and the application range is small. There is no systematic method for analyzing and researching the slope with small deformation and depth exceeding 200 meters. ​​​​​

[0099] To solve the above problems, the present disclosure analyzes the SAA data monitoring curve obtained according to the SAA data, determines the type of the corresponding slope deformation depth range according to the numerical relationship between different displacements monitored in the analysis process, and determines the depth of the slope deformation depth range according to the corresponding relationship between the displacement and the depth of the SAA data monitoring curve, thereby realizing analysis based on the SAA data monitoring curve, determining the monitoring result with large measurement depth and small deformation, improving the accuracy and efficiency of slope deformation analysis, and improving the landslide early warning effect.

[0100] The slope deformation analysis method described in the embodiments of the present disclosure can be applied to a slope deformation analysis device or an electronic device, wherein the slope deformation analysis device can be a functional module and / or a functional entity that can realize the slope deformation analysis method in the electronic device.

[0101] The electronic device described above can include a smartphone (such as an Android phone, an IOS phone, a Windows Phone phone, etc.), a tablet computer, a palm computer, a notebook computer, a video matrix, a monitoring platform, a mobile Internet device (MID, Mobile Internet Devices) or a wearable device, a server, for example, a cloud server, and the like. The above are only examples and are not exhaustive, and include but are not limited to the above devices.

[0102] In order to more clearly illustrate the technical solutions in the embodiments of the present disclosure or the prior art, the technical terms needed to be used in the embodiments or the prior art description will be briefly introduced below.

[0103] The array displacement accelerometer (Shape Acceleration Array, SAA) measures two-dimensional and three-dimensional deformation using a set of precise microelectromechanical system accelerometers (MEMS) array and a verified calculation program. There is no priority axis, free bending and can be installed vertically and horizontally. The inclination of a single node relative to the direction of gravity is measured using MEMS. According to the calibration file generated when manufactured, the accelerometer axis is aligned, forming a continuous orthogonal axis for each X, Y and Z.

[0104] Figure 1A For the application scenario of the slope deformation analysis method in the embodiments of the present disclosure, the devices in the figure are the array displacement accelerometer SAA 110 and the cloud platform 120. In actual application, the SAA 110 is buried in the slope to be analyzed, monitors the displacement data of the slope, and then transmits to the cloud platform for slope deformation analysis.

[0105] Figure 1BA schematic diagram of device SAA110 data processing is shown in the figure. SAA110 monitors the inclination of a single joint relative to the direction of gravity in three-dimensional space to obtain the displacement of the slope at each monitoring point. The displacement is a vector. When the cloud platform generates the SAA monitoring curve, the displacement in different directions x, y, and z of each monitoring point is subjected to vector operation, and then the displacement vector is converted into a scalar to represent the deformation of the slope corresponding to the monitoring point. The depth corresponding to each monitoring point can be determined, and the distance of the slope moving relative to the direction of gravity can be determined.

[0106] Figure 2 A flowchart of a slope deformation analysis method according to an embodiment of the present disclosure is shown in the figure. The method comprises:

[0107] S202, acquiring array displacement accelerometer SAA monitoring data for the slope.

[0108] In some embodiments, since the array displacement accelerometer SAA is vertically buried in the slope, the SAA monitors the displacement caused by the deformation of the slope, and collects and sends the monitored SAA monitoring data to the cloud platform, so as to generate the SAA monitoring data curve according to the SAA monitoring data, and subsequently analyze according to the SAA monitoring curve.

[0109] S204, acquiring a plurality of SAA data monitoring curves at different times according to the SAA monitoring data.

[0110] The SAA data monitoring curve represents the relationship between the depth of the SAA to the surface of the slope and the displacement of the slope.

[0111] In some embodiments, due to the influence of factors such as SAA device embedding process, early deformation difference of rock stratum, etc., there are differences in hole diameter and confining pressure, so that there are error curves in the several SAA data monitoring curves generated according to the SAA monitoring data. The error curve is usually drawn by the early collected SAA monitoring data, so it is necessary to analyze the early SAA monitoring data curve first.

[0112] It should be noted that the slope deformation analysis method provided by the present disclosure does not process the monitoring data within a preset time period, for example, the deformation of a certain monitoring point within two years is less than 1mm. The above situation may be caused by irrelevant factors such as ground vibration and slope water content change, and it can be determined that the slope is in a stable state. Therefore, the present disclosure does not process the monitoring data within a preset time period, for example, the deformation of a certain monitoring point within two years is less than 1mm.

[0113] The first monitoring curve with the earliest time will be analyzed as follows:

[0114] In some embodiments, as Figure 3As shown, according to the first monitoring curve Y1 in the plurality of SAA data monitoring curves, that is, the monitoring curve of the data collected in the first month after the SAA device is buried, and any monitoring curve Y2 other than the first monitoring curve, first, the displacement of the monitoring endpoints of the two monitoring curves is determined: the displacement A of the upper endpoint and the displacement B of the lower endpoint of the first monitoring curve Y1, and the displacement M of the upper endpoint and the displacement N of the lower endpoint of the monitoring curve Y2, the deformation amount C of the displacement A and the displacement B is calculated, C=A-B, and the deformation amount S of the displacement M and the displacement N is calculated, S=M-N, and then whether the difference between the deformation amount C and the deformation amount S is less than a preset difference value is calculated; if the difference between the deformation amount C and the deformation amount S is less than the preset difference value, the maximum displacement of the two monitoring curves is determined, the maximum displacement of the first monitoring curve Y1 is P, and the maximum displacement of the monitoring curve Y2 is Q, the deformation amount T of the maximum displacement P and the maximum displacement Q is calculated, T=Q-P, and if the deformation amount T is greater than the preset difference value, the depths y3 and y4 of the monitoring points corresponding to the maximum displacement P and the maximum displacement Q are further determined;

[0115] If the depth of the monitoring point corresponding to the maximum displacement P and the depth of the monitoring point corresponding to the maximum displacement Q are different, the monitoring curve Y1 is divided into two parts: A-P and P-B; correspondingly, the monitoring curve Y2 is divided into two parts: M-Q and Q-N; in some embodiments, the P-Q segment curve is obtained after the division. Among them, A-P is the part curve from the upper endpoint A to the depth of the monitoring point corresponding to the maximum displacement P, P-B is the part curve from the depth of the monitoring point corresponding to the maximum displacement P to the lower endpoint B, M-Q is the part curve from the upper endpoint M to the depth of the monitoring point corresponding to the maximum displacement Q, and Q-N is the part curve from the depth of the monitoring point corresponding to the maximum displacement Q to the lower endpoint N; P-Q is the part curve of the detection curve Y1 from the depth corresponding to P to the depth corresponding to Q, or the part curve of the detection curve Y2 from the depth corresponding to P to the depth corresponding to Q.

[0116] After the monitoring curve Y1 and the monitoring curve Y2 are divided, it is detected whether there is a monitoring point with the same depth but negative deformation amount in the A-P segment curve corresponding to the M-Q segment curve, if there is, it is determined that there is an error in the data collected by the first monitoring curve Y1 due to problems in the burying process, and the subsequent analysis process will not be performed on the first monitoring curve; it should be noted that the detection process can be combined with the A-P segment curve and the P-Q segment curve; correspondingly, it is detected whether there is a monitoring point with the same depth but negative deformation amount in the P-B segment curve corresponding to the Q-N segment curve, if there is, it is determined that there is an error in the data collected by the first monitoring curve Y1 due to problems in the burying process, and the subsequent analysis process will not be performed on the first monitoring curve.

[0117] Correspondingly, a second SAA data monitoring curve in the time dimension can be determined, and whether the second SAA data monitoring curve meets the analysis condition is determined through the same principle and operation steps as described above. If the second SAA data monitoring curve meets the analysis condition, that is, the data change trend is similar after comparison with other monitoring curves, it is determined that the SAA equipment corresponding to the second SAA data monitoring curve reaches the original confining pressure at the time, and the SAA data monitoring curves collected subsequently can be used for slope deformation analysis.

[0118] It should be noted that, in order to further ensure the accuracy of the slope deformation analysis, the SAA monitoring curves in the preset time range can be analyzed as described above. For example, the preset time range is two months after the SAA equipment is buried, and the first monitoring curve and the second monitoring curve in the SAA monitoring curves need to be analyzed to determine whether the two monitoring curves have errors caused by factors such as equipment burial process and early deformation difference of rock stratum. If it is determined that the first monitoring curve has errors and the second monitoring curve does not have errors, it is indicated that the SAA equipment corresponding to the second monitoring curve has reached the original confining pressure at the time, and the SAA monitoring results at subsequent times are reliable, so the subsequent analysis takes the second monitoring curve as a reference.

[0119] In some embodiments, after it is determined that the SAA equipment corresponding to the second SAA data monitoring curve reaches the original confining pressure at the time, the data contained in the second SAA data monitoring curve can be used to process the data contained in other SAA data monitoring curves. Optionally, an embodiment of the present disclosure provides a method of subtracting the data contained in the second SAA data monitoring curve corresponding to the depth from the data contained in other SAA data monitoring curves to obtain actual SAA data monitoring curves at other times, so as to use the actual SAA data monitoring curves processed according to the second monitoring curve for slope deformation analysis.

[0120] The above embodiments compare the change trends of the monitoring curves by calculating the deformation amounts of the end points in the monitoring curves and the deformation amounts of the maximum displacements, so as to determine whether the change trends of the monitoring curves are consistent, to determine the monitoring curve that reaches the original confining pressure, and to exclude the influence caused by the equipment burial process, the difference in depth and aperture, and the early deformation difference of rock and soil, thereby further improving the accuracy of the slope deformation analysis.

[0121] S206, determining a first displacement of a first monitoring point corresponding to a first depth value and a second displacement of a second monitoring point corresponding to a second depth value from each SAA data monitoring curve.

[0122] In some embodiments, in the case of errors in the first monitoring curve with the earliest time, for the analysis of slope deformation, the displacement corresponding to the same depth value needs to be determined from each SAA data monitoring curve (except the first monitoring curve with errors) to determine a plurality of groups of first displacement and second displacement corresponding to a plurality of SAA data monitoring curves for subsequent analysis.

[0123] S208, determining the deformation type and deformation depth of the target slope depth range according to the plurality of groups of first displacement and second displacement.

[0124] Wherein, the target slope depth range is the slope depth range between the first depth value and the second depth value.

[0125] The present disclosure determines the type of slope deformation depth range according to the first displacement of the first monitoring point and the second displacement of the second monitoring point determined from the array displacement accelerometer SAA data monitoring curve, including but not limited to: overall displacement, rock-soil swelling deformation, extrusion creep deformation, local creep deformation, and the following will introduce the analysis process S206-S208 taking the above types as examples.

[0126] (1) Overall displacement

[0127] In some embodiments, after analyzing the monitoring curve with the earliest time, after excluding errors caused by factors such as device embedding process, different depth aperture differences, and early rock-soil deformation differences, at least two SAA data monitoring curves are determined from a plurality of SAA data monitoring curves. For ease of explanation and description, the following will be described taking two SAA data monitoring curves as an example.

[0128] For example, as shown in FIG. 6, the first SAA data monitoring curve and the second SAA data monitoring curve are determined from a plurality of SAA data monitoring curves. Figure 4As shown, two SAA data monitoring curves, monitoring curve Y3 and monitoring curve Y4, are determined from the plurality of SAA data monitoring curves, and then the first displacement A1 and the second displacement B1 are determined from the monitoring curve Y3, and the first displacement M1 and the second displacement N1 are determined from the monitoring curve Y4, wherein the first displacement A1 and the first displacement M1 correspond to the same depth y1, and the second displacement B1 and the second displacement N1 correspond to the same depth y2; then the first deformation S1 between the first displacement A1 and the first displacement M1 is calculated as S1=M1-A1, and the second deformation T1 between the second displacement B1 and the second displacement N1 is calculated as T1=N1-B1; further, the difference H1 between the first deformation S1 and the second deformation T1 is calculated, and the absolute value of the difference H1 is taken, that is, the difference H1 is a positive number, and whether the difference H1 is less than a preset difference is judged; for example, the preset difference is 0.01 millimeters, and if the difference H1 is less than the preset difference, it indicates that the overall displacement of the target depth range slope body is basically unchanged, and it can be determined that the type of the target slope body deformation depth range is overall displacement, and it indicates that the depth range corresponding to the first depth value y1 to the second depth value y2 is the overall displacement zone.

[0129] Further, the depth of the overall displacement zone is determined according to the corresponding relationship between the first displacement A1 and the second displacement B1 and the depth in the monitoring curve Y3 and the monitoring curve Y4.

[0130] It should be noted that the target depth range is determined by at least two monitoring points, but the number of monitoring points included in the target depth range is not specifically limited, and the analysis of the depth values and displacements corresponding to different monitoring points can determine the slope body deformation depth of a larger depth range or a smaller depth range, and the target slope body depth is the depth value selected for one analysis, so the deformation depth determined according to other monitoring points can be equal to the target depth range, can be greater than the target depth range, or can be less than the target depth range.

[0131] In the above embodiments, by determining the displacements corresponding to different depth values from the plurality of SAA data monitoring curves, comparing the difference between the deformations, taking the depth range with basically unchanged deformation as the target slope body deformation depth range of the type of overall displacement, and determining the depth of the overall displacement zone, the type of slope body deformation is determined in the slope body with large depth and small deformation, and thus the analysis result is used for early warning.

[0132] (2) Swelling deformation of rock-soil mass

[0133] In some embodiments, as Figure 5As shown, two SAA data monitoring curves, monitoring curve Y5 and monitoring curve Y6, are determined from a plurality of SAA data monitoring curves, and then a first displacement A2 and a second displacement B2 are determined from the monitoring curve Y5, and a first displacement M2 and a second displacement N2 are determined from the monitoring curve Y6, wherein the first displacement A2 and the first displacement M2 correspond to the same depth y1, and the second displacement B2 and the second displacement N2 correspond to the same depth y2.

[0134] Further, a first deformation S2 between the first displacement A2 and the first displacement M2 is calculated, S2 = M2-A2, and a second deformation T2 between the second displacement B2 and the second displacement N2 is calculated, T2 = N2-B2; further, a difference H2 between the first deformation S2 and the second deformation T2 is calculated, and it is judged whether the difference H2 is less than a preset difference value;

[0135] If the difference H2 is less than the preset difference value, a maximum displacement P1 is determined from the monitoring curve Y5, and a maximum displacement Q1 is determined from the monitoring curve Y6, and then a third deformation S3 = Q1-P1 of the maximum displacement P1 and the maximum displacement Q1 is calculated; then, a difference H3 between the first deformation S2 and the third deformation S3 is calculated, and a difference H4 between the second deformation T2 and the third deformation S3 is calculated, and it is judged whether the difference H3 is greater than the preset difference value, and / or whether the difference H4 is greater than the preset difference value;

[0136] If the difference H3 is greater than the preset difference value, and the depths corresponding to the maximum displacement P1 and the maximum displacement Q1 are the same, both being y3, it is determined that the type of the slope deformation depth range is the rock-soil swelling deformation zone; it should be noted that in actual application, the depths corresponding to the maximum displacement P1 and the maximum displacement Q1 can be set within a preset depth range, for example, the preset depth range is 1 meter, and the maximum displacement P1 and the maximum displacement Q1 are within a depth difference range of 1 meter, and the type of the slope deformation depth range can be determined as the rock-soil swelling deformation zone;

[0137] If the difference H4 is greater than the preset difference value, and the depths corresponding to the maximum displacement P1 and the maximum displacement Q1 are the same, both being y3, it is determined that the type of the slope deformation depth range is the rock-soil swelling deformation zone;

[0138] If the difference H3 is greater than the preset difference value, the difference H4 is greater than the preset difference value, and the depths corresponding to the maximum displacement P1 and the maximum displacement Q1 are the same, both being y3, it is determined that the type of the slope deformation depth range is the rock-soil swelling deformation zone.

[0139] Further, according to the corresponding relationship between the first displacement A2 and the second displacement B2 and the depth in the monitoring curve Y5 and the monitoring curve Y6, the depth of the overall displacement zone is determined to be y1 meters to y2 meters.

[0140] (3) Local creep deformation

[0141] In some embodiments, such as Figure 6 As shown, taking the lower detection point of the SAA device as the origin of the coordinate system, the first depth value y1 is less than the second depth value y2, meaning the first monitoring point is closer to the slope surface than the second monitoring point. Furthermore, comparing the first displacement A3 corresponding to the first depth value y1 with the second displacement B3 corresponding to the second depth value y2, we find that the first displacement A3 is greater than the second displacement B3. Additionally, comparing the first displacement M3 corresponding to the first depth value y1 with the second displacement N3 corresponding to the second depth value y2 in the monitoring curve Y8, we find that the first displacement M3 is greater than the second displacement N3. This indicates that the displacement is smaller at locations with greater slope depth, and larger at locations with less slope depth. Based on... Figure 6 It can be seen that the deformation is smaller at deeper locations, and the displacement is greater at shallower depths (along the longitudinal axis).

[0142] Furthermore, it is determined whether the difference between the first depth value y1 and the second depth value y2 is within the preset depth range. If the difference between the first depth value y1 and the second depth value y2 is within the preset depth range, it indicates that the slope has a large deformation within a small depth range and shows a rapid changing trend. The target slope depth range can be determined as a local creep deformation zone.

[0143] In some embodiments, such as Figure 7 As shown, if the difference between the first depth value y1 and the second depth value y2 is within a preset depth range, the maximum displacement in each SAA data monitoring curve can be further determined. The maximum displacement in monitoring curve Y9 is determined to be P2 and the maximum displacement in monitoring curve Y10 is determined to be Q2. If the maximum displacement P2 is greater than or equal to the first displacement A4, the depth range between the first depth value and the second depth value is determined to be the local creep depth range. When the maximum displacement is greater than or equal to the first displacement, the local creep depth range will experience slippage.

[0144] Furthermore, the slope depth range between the first depth value y1 and the second depth value y2 is defined as the local creep depth range, within which landslides occur. The landslide range can be determined based on the depth value corresponding to the maximum displacement.

[0145] (4) Extrusion creep deformation

[0146] In some embodiments, such as Figure 8As shown, taking the lower end detection point of the SAA device as the coordinate origin, the first depth value y3 is less than the second depth value y4, that is, the first monitoring point is closer to the surface of the slope body than the second monitoring point, and the first displacement A5 corresponding to the first depth value y3 is compared with the second displacement B5 corresponding to the second depth value y4, and it is obtained that the first displacement A5 is greater than the second displacement B5; and the first displacement M5 corresponding to the first depth value y3 in the monitoring curve Y12 is compared with the second displacement N5 corresponding to the second depth value y4, and it is obtained that the first displacement M5 is greater than the second displacement N5, indicating that the displacement amount of the position with a larger slope body depth is smaller, and the displacement amount of the position with a smaller depth is larger; according to Figure 6 It can be seen that the deformation amount of the position with a deeper depth is smaller, and the displacement is larger (in the longitudinal axis direction) as the depth is smaller.

[0147] Further, it is judged whether the difference between the first depth value y3 and the second depth value y4 is within the preset depth range, and if the difference between the first depth value and the second depth value is not within the preset depth range, it indicates that there is a larger deformation in the larger depth range of the slope body, and the slope body deforms slowly, and it can be determined that the target slope body deformation depth range corresponding to the first depth value and the second depth value is the extrusion creep deformation zone.

[0148] It should be noted that since the extrusion creep deformation zone is usually a transition section of the overall displacement zone, after determining the extrusion creep deformation zone according to the monitoring data analysis, the depth range adjacent to the extrusion creep deformation zone needs to be analyzed to determine the monitoring data monitored by the monitoring points adjacent to the depth range, so as to further determine the depth range of the extrusion creep deformation zone, and accordingly the depth value of the overall displacement zone can be obtained, that is, the depth at which the slope body is likely to deform obviously is determined, so that the deformation amount at the depth can be focused on in the subsequent process, so that the deformation of the slope body can be determined as early as possible, and the technical personnel are reminded to take precautions.

[0149] In the above embodiment, the case that the first displacement is greater than the second displacement is obtained by analysis, and it is determined that the slope body has local creep, and further, it is judged whether the local creep depth range has a sliding body according to the maximum displacement of the monitoring curve, so as to give a warning and take precautions according to the analysis result.

[0150] In summary, the present disclosure analyzes the SAA data monitoring curve obtained according to the SAA data, determines the type of the corresponding slope body deformation depth range according to the numerical relationship between the different displacements monitored in the analysis process, and determines the depth of the slope body deformation depth range according to the corresponding relationship between the displacement and the depth of the SAA data monitoring curve, so as to realize the analysis based on the SAA data monitoring curve, determine the monitoring result with a large measurement depth and a small deformation amount, improve the accuracy and efficiency of the slope body deformation analysis, and improve the landslide warning effect.
