[0056] In the related art, since most of the slopes of hydropower stations are in a basically stable but locally unstable state, the probability of overall rapid sliding is small, but their continuous creeping deformation will seriously affect the safety of nearby residential areas and roads.

[0057] At present, the traditional slope displacement warning method is to detect the displacement degree of preset measuring points, and judge whether there are potential safety hazards on the slope based on the single factor of the displacement amount of the measuring points. This method is difficult to accurately and timely monitor the actual displacement of the slope, and then it is impossible to timely make effective countermeasures against the potential safety hazards existing in the slopes of hydropower stations.

[0058] To solve the above problems, the present disclosure provides a method, device and system for monitoring the displacement of a reservoir near-dam slope, which includes obtaining first displacement information of a preset target measuring point on the reservoir near-dam slope; obtaining the coordinates of each measuring point in at least one group of displacement measuring points; each group of displacement measuring points in the at least one group of displacement measuring points includes a first displacement measuring point and a second displacement measuring point; the first measuring point is located at the top of the reservoir near-dam slope, and the second measuring point is located at the bottom of the reservoir near-dam slope; each group of displacement measuring points is located on a preset representative section of the reservoir near-dam slope; for each group of displacement measuring points, generating a reference line connecting the first displacement measuring point and the second displacement measuring point; obtaining an initial reference line between the first displacement measuring point and the second displacement measuring point; the initial reference line is the reference line generated before the reservoir near-dam slope undergoes displacement; determining the degree of length change of the reference line relative to the initial reference line according to the reference line and the initial reference line; determining the degree of angular change of the reference line relative to the initial reference line according to the reference line and the initial reference line; determining the displacement grade of the reservoir near-dam slope based on the first position information, the degree of length change and the degree of angular change. By combining the displacement information of multiple target monitoring points, the degree of length change and the degree of angular change of multiple reference lines, it is possible to comprehensively and accurately judge the displacement deformation degree of the reservoir near-dam slope, thereby improving the accuracy of slope displacement monitoring, and then being able to timely and effectively make effective countermeasures against the potential safety hazards existing in the slopes of hydropower stations.

[0059] Figure 1 is a flowchart of a method for monitoring the displacement of a reservoir near-dam slope shown according to an exemplary embodiment. As Figure 1 shown, it should be noted that the method for monitoring the displacement of the reservoir near-dam slope in the embodiments of the present disclosure is applied to a device for monitoring the displacement of the reservoir near-dam slope. As Figure 1 shown, the method may include the following steps:

[0060] Step 101, obtaining first displacement information of a preset target measuring point on the reservoir near-dam slope.

[0061] In the embodiments of the present application, multiple measurement points are arranged on the slope near the reservoir dam. In order to improve the monitoring efficiency of the slope and promptly discover the risks caused by slope displacement, at least one representative measurement point can be selected as the target measurement point, thereby reducing the calculation amount and improving the monitoring efficiency.

[0062] In one embodiment, the first displacement information can be collected by using UWB base stations and displacement tags arranged on the slope. As Figure 2 shown, the slope 5 to be measured is selected. Among the multiple measurement points 1 on the slope 5, 3 groups of target measurement points 2 (including A0B0, A1B1, A2B2) are selected. UWB base stations are arranged outside the landslide perimeter 3, and one base station is arranged every 20 - 30 m along the landslide perimeter 3. The base station type can be selected as a lightning protection, explosion-proof, and waterproof base station. UWB positioning tags are arranged at the measurement points to be measured on the slope 5, and the positioning tags can be selected with a waterproof and large battery capacity model. The target measurement points 2 are arranged on the representative sliding surface of the landslide body. In order to prevent being buried, the base of the measurement point 2 can be set slightly higher than the ground.

[0063] Among them, the UWB positioning module utilizes the high-precision ranging characteristics of ultra-wideband signals, is not affected by vegetation conditions, has high positioning accuracy, and accurately calculates the distance and relative position between nodes by measuring the propagation time of signals between different nodes.

[0064] It should be noted that the representative sliding surface is parallel to the landslide sliding direction, located in the middle of the landslide body and has a length close to the longest section.

[0065] In some embodiments of the present application, before step 101, the method may further include:

[0066] Obtain the historical displacement amounts of all measurement points on the slope near the reservoir dam within a preset historical time period;

[0067] Remove the measurement points with abnormal historical displacement amounts from all measurement points to obtain a candidate set of measurement points;

[0068] Select the n measurement points with the largest historical displacement amounts from the candidate set of measurement points as the target measurement points; n is an integer greater than 1.

[0069] In one embodiment, the above preset historical time period is a time period when obvious slope displacement may occur. For example, the preset historical time period can be the flood season, or it can be the heavy rain period, or it can also be the time period when construction activities are carried out on the slope.

[0070] In one embodiment, the measurement points without readings or with historical displacement amounts of 0 or with displacement amounts more than three times that of other measurement points can be removed from all measurement points to obtain a candidate set of measurement points after removing the obviously incorrect measurement points.

[0071] In one embodiment, n measuring points with the largest historical displacement are selected from the candidate measuring points, and n can be set according to actual requirements. After removing abnormal measuring points from all the measuring points on the near-dam slope of the reservoir, several measuring points with the largest displacement are selected as the target measuring points, which can ensure the accuracy of the collected data while reducing the amount of data calculation and improving the monitoring efficiency of the slope displacement.

[0072] Step 102: Obtain the coordinates of each measuring point in at least one set of displacement measuring points.

[0073] Among them, each set of displacement measuring points in at least one set of displacement measuring points includes a first displacement measuring point and a second displacement measuring point; the first measuring point is located at the top of the near-dam slope of the reservoir, and the second measuring point is located at the bottom of the near-dam slope of the reservoir; each set of displacement measuring points is located on a preset representative section of the near-dam slope of the reservoir.

[0074] For example, as Figure 2 shown, the first measuring points located at the top of the slope are A0, A1, and A2, and the second measuring points located at the bottom of the slope are B0, B1, and B2.

[0075] It should be noted that the representative section of the slope comprehensively reflects the landslide characteristics. The geological structure of the landslide is complex, and the sliding surface forms (such as straight lines, curves, and broken lines), stratum combinations (such as soft interlayers and argillized zones), and deformation characteristics at different positions may vary significantly. By selecting multiple typical sections (such as the main sliding direction, both sides' boundaries, or different geological units), the spatial variation law of the landslide body can be systematically captured, avoiding the one-sidedness of a single section. In addition, selecting a representative section can transform the three-dimensional problem into a two-dimensional problem, and among them, the central axis is the most representative section.

[0076] Therefore, by selecting the first measuring point located at the top of the slope and the second measuring point located at the bottom of the slope from the preset representative section, and evaluating the displacement degree of the slope based on the connection line between the first measuring point and the second measuring point on the same representative slope, the three-dimensional problem is transformed into a two-dimensional problem, reducing the monitoring difficulty of the slope displacement and improving the monitoring efficiency and accuracy.

[0077] In one embodiment, as Figure 2 shown, the section where the median line of slope 5 is located and the slopes on both sides of the median line can be selected as the representative sections, and three sets of displacement measuring points A0B0, A1B1, and A2B2 are obtained according to the above three representative sections. The spacing between the above three sections can be set according to actual requirements.

[0078] Step 103: For each set of displacement measuring points, generate a reference line connecting the first displacement measuring point and the second measuring point.

[0079] In one embodiment, a connection line between a first displacement measurement point and a second displacement measurement point belonging to the same group may be generated to obtain the above-mentioned reference line for evaluating the displacement degree of the slope based on the reference line.

[0080] For example, as Figure 2 shown, for the three groups of displacement measurement points A0B0, A1B1, and A2B2, 3 reference lines 4 are obtained.

[0081] Step 104, obtain the initial reference line between the first displacement measurement point and the second measurement point.

[0082] Wherein, the initial reference line is the reference line generated before the reservoir near-dam slope has displacement.

[0083] In one embodiment, the initial reference line may be generated at the beginning of the completion of the reservoir construction according to the reference line generation method proposed in the embodiments of the present application, that is, the initial reference line is the reference line when the slope has no displacement and is in a stable state.

[0084] Step 105, determine the degree of length change of the reference line relative to the initial reference line according to the reference line and the initial reference line.

[0085] In one embodiment, the deformation degree of the slope may be evaluated according to the degree of length change between the reference line and the initial reference line, that is, the degree of distortion of the overall shape of the slope is evaluated.

[0086] In some embodiments of the present application, as Figure 3 shown, AB is the initial reference line, A'B' is the reference line, and the length change rate from AB to A'B' is ω. Step 105 may specifically include the following steps:

[0087] Respectively determine the first length of the reference line and the second length of the initial reference line;

[0088] Calculate the length change rate of the reference line relative to the initial reference line through the following formula to obtain the degree of length change:

[0089]

[0090] Wherein, ω is the length change rate, L is the second length, and L' is the first length.

[0091] In one embodiment, the change trend of the slope displacement, that is, the speed of the slope displacement, may be evaluated according to the length change rate of the reference line relative to the initial reference line.

[0092] Step 106, determine the degree of angle change of the reference line relative to the initial reference line according to the reference line and the initial reference line.

[0093] In some embodiments of the present application, step 106 may specifically include the following steps:

[0094] Determine the angle between the reference line and the initial reference line as the angle change amount of the reference line relative to the initial reference line, and obtain the degree of angle change.

[0095] In one embodiment, the angle change amount may be determined according to the magnitude of the angle between the reference line and the initial reference line, and then the displacement degree of the slope can be evaluated through the angle change amount, that is, the degree of distortion of the overall shape of the slope can be evaluated. For example Figure 4 As shown, AB is the initial reference line, A'B' is the reference line, and the length change rate from AB to A'B' is α.

[0096] Step 107, based on the first position information, the degree of length change, and the degree of angle change, determine the displacement grade of the reservoir near-dam slope.

[0097] In one embodiment, the displacement grade of the reservoir near-dam slope can be comprehensively judged according to the length change degree and angle change degree of multiple target measurement points and the reference line.

[0098] In some embodiments of the present application, the first displacement information includes the displacement amount and displacement acceleration of the target measurement point, and step 107 may specifically include the following steps:

[0099] Obtain a first mapping relationship table including the mapping relationship between the displacement amount and displacement acceleration of the target measurement point, the length change rate and angle change amount of the reference line, and the displacement grade of the reservoir near-dam slope;

[0100] Select the displacement grade of the reservoir near-dam slope that matches the first position information, the degree of length change, and the degree of angle change from the first mapping relationship table.

[0101] For example, the first mapping relationship table may be as shown in Table 1:

[0102] Table 1 First mapping relationship table and recommended treatment plan

[0103]

[0104]

[0105] It should be noted that each target measurement point and each reference line must meet the corresponding conditions in the first mapping relationship table to determine the displacement grade of the reservoir near-dam slope.

[0106] In some embodiments of the present application, after step 107, the following steps may further be included:

[0107] Output early warning information according to the displacement level of the near-dam slope of the reservoir, and generate a treatment plan for slope displacement based on the displacement level of the near-dam slope of the reservoir.

[0108] In one embodiment, after obtaining the displacement level of the near-dam slope of the reservoir, a recommended treatment plan for slope displacement can be selected from the first mapping relationship table according to the displacement level of the near-dam slope of the reservoir for the reference of the staff.

[0109] According to the reservoir near-dam slope displacement monitoring method proposed by the embodiments of the present disclosure, by obtaining the first displacement information of a preset target measurement point on the near-dam slope of the reservoir; obtaining the coordinates of each measurement point in at least one group of displacement measurement points; each group of displacement measurement points in at least one group of displacement measurement points includes a first displacement measurement point and a second displacement measurement point; the first measurement point is located at the top of the near-dam slope of the reservoir, and the second measurement point is located at the bottom of the near-dam slope of the reservoir; each group of displacement measurement points is located on a preset representative section of the near-dam slope of the reservoir; for each group of displacement measurement points, generate a reference line connecting the first displacement measurement point and the second displacement measurement point; obtain the initial reference line between the first displacement measurement point and the second displacement measurement point; the initial reference line is the reference line generated before the near-dam slope of the reservoir undergoes displacement; according to the reference line and the initial reference line, determine the degree of length change of the reference line relative to the initial reference line; according to the reference line and the initial reference line, determine the degree of angular change of the reference line relative to the initial reference line; based on the first position information, the degree of length change, and the degree of angular change, determine the displacement level of the near-dam slope of the reservoir. By combining the displacement information of multiple target monitoring points, the degree of length change and the degree of angular change of multiple reference lines, it is possible to comprehensively and accurately judge the displacement deformation degree of the near-dam slope of the reservoir, thereby improving the accuracy of slope displacement monitoring, and then being able to timely and effectively take effective countermeasures against the potential safety hazards existing in the slopes of hydropower stations.
