[0023] like Figure 1 As shown, an embodiment of the present invention provides a slope early warning method, comprising the following steps: S100: Acquire deformation monitoring data of each area in the target slope, and determine a first warning result for each area in the target slope based on the deformation monitoring data of each area.

[0024] In some embodiments, the various regions of the target slope may be regions divided according to the geological conditions of the target slope. For example, the target slope may be divided into multiple regions according to ditch-ridge topography or fissure cuts.

[0025] In some embodiments, the deformation monitoring data may be displacement monitoring data of a fixed point obtained by measuring the three-dimensional coordinates of the fixed point at multiple time points. The displacement monitoring data for each region of the target slope includes surface displacement monitoring data and deep underground displacement monitoring data. In other embodiments, the deformation monitoring data may also be stress monitoring data of a fixed point deep underground.

[0026] In some embodiments, the first warning result may be five warning levels, which are normal, blue, yellow, orange, and red from low to high.

[0027] S200: Obtain a second warning result output by the radar monitoring device based on radar data of the target slope.

[0028] Specifically, when the target slope is monitored by a radar monitoring device, the deformation per unit area of ​​the target slope is monitored by the radar monitoring device.

[0031] Specifically, the image data of the target slope can be the video data of the target slope, and the video data can be high-definition infrared video data. A high-definition infrared video monitoring device is used to monitor the target slope 24 hours a day to monitor the number of landslides and the amount of landslides on the target slope for 24 hours, and the third warning result is determined based on the number of landslides and the amount of landslides.

[0033] S400: Obtaining a fourth warning result output by the earthquake monitoring device based on earthquake monitoring data of the target slope.

[0034] Specifically, when using an earthquake monitoring device to monitor the target slope, the earthquake acceleration measurement value is compared with the strong earthquake threshold. As long as a strong earthquake occurs, the fourth warning result is a red warning. When no strong earthquake occurs, the fourth warning result is normal.

[0035] S500: Acquire a fifth warning result output by the environmental monitoring device based on the environmental data of the target slope.

[0036] Specifically, an environmental monitoring device is used to monitor the rainfall on the target slope, and a fifth early warning result is output based on the monitoring result of the rainfall.

[0037] Similar to the first warning result, the second warning result and the third warning result mentioned above, the fifth warning result can be five warning levels, which are normal, blue, yellow, orange and red from low to high.

[0038] S600: Outputting a final warning result of the target slope according to the first warning result, the second warning result, the third warning result, the fourth warning result and the fifth warning result.

[0039] In some embodiments, the warning result with the highest level among the first warning result, the second warning result, the third warning result, the fourth warning result, and the fifth warning result can be selected as the final warning result. In other embodiments, different values ​​can be assigned to different levels of warning results. For example, the warning levels are normal (denoted as 0), blue (denoted as 1), yellow (denoted as 2), orange (denoted as 3), and red (denoted as 4) from low to high, and different weights are assigned to the first warning result, the second warning result, the third warning result, the fourth warning result, and the fifth warning result. After weighting the first warning result, the second warning result, the third warning result, the fourth warning result, and the fifth warning result according to the different weights, the final warning result can be obtained.

[0040] In this embodiment, deformation monitoring data of each area in the target slope is obtained, and based on the deformation monitoring data of each area, a first warning result of each area in the target slope is determined, and a first warning result based on the deformation monitoring data is provided through the deformation monitoring data of the slope; a second warning result based on the radar data output by the radar monitoring device of the target slope is obtained, and a second warning result based on the radar data is provided through the radar data of the slope; a third warning result based on the image data output by the image monitoring device of the target slope is obtained, and a third warning result based on the image data is provided through the image data of the slope; a fourth warning result based on the earthquake monitoring data output by the earthquake monitoring device of the target slope is obtained, and a fourth warning result based on the earthquake monitoring data of the slope is provided. The earthquake monitoring data provides a fourth warning result based on the earthquake monitoring data; the fifth warning result output by the environmental monitoring device based on the environmental data of the target slope is obtained, and the fifth warning result based on the environmental data is provided through the environmental data of the slope; according to the first warning result, the second warning result, the third warning result, the fourth warning result and the fifth warning result, the final warning result of the target slope is output. Combined with the warning results corresponding to the above-mentioned displacement, radar, environment, earthquake and image monitoring data, it can fully reflect the status of the slope, realize comprehensive monitoring of the slope, and associate multiple warning results to output the final warning result, so as to avoid some potential safety hazards from being monitored, thereby improving the accuracy of slope warning.

[0041] Optionally, the target slope includes at least a deformation area and a non-deformation area.

[0042] Specifically, the various areas of the target slope can be deformation areas and non-deformation areas divided according to geological conditions and deformation conditions, and can be determined through geological exploration. Among them, the surface of the deformation area has gravel and signs of landslides, and the surface of the non-deformation area has no obvious gravel and landslide signs.

[0043] The deformation area is provided with a plurality of first monitoring points and a plurality of second monitoring points, the first monitoring points are located at the surface part of the deformation area, and the second monitoring points are located at the underground part of the deformation area.

[0044] The non-deformation area is provided with a plurality of third monitoring points and a plurality of fourth monitoring points. The third monitoring points are located at the surface part of the non-deformation area, and the fourth monitoring points are located at the underground part of the non-deformation area.

[0045] The first monitoring point and the second monitoring point are used to provide deformation monitoring data of the deformation area, and the third monitoring point and the fourth monitoring point are used to provide deformation monitoring data of the non-deformation area.

[0046] Specifically, to maintain consistency, the total number of monitoring points in each area is the same, M.

[0047] In some embodiments, each of the first, second, third, and fourth monitoring points is provided with a position sensor configured to obtain position information of the corresponding monitoring point. By monitoring the position data collected by the position sensor at each monitoring point, displacement changes at each monitoring point can be obtained, i.e., displacement monitoring data. Specifically, the position data collected by the position sensor can be three-dimensional position data.

[0048] In other embodiments, the second and fourth monitoring points, which are located underground, may also be equipped with stress sensors for acquiring stress information at the corresponding monitoring points. By monitoring the stress data collected by the stress sensors at each monitoring point, stress changes at each monitoring point can be determined, thereby generating stress monitoring data.

[0049] In this optional embodiment, for the deformation area and the non-deformation area, the position data (stress data) of each monitoring point on the surface and each monitoring point underground in the area are monitored respectively to obtain the deformation conditions of each monitoring point, so as to collect the deformation monitoring data of each area in the target slope more comprehensively, and provide comprehensive and accurate data support for the subsequent determination of the first warning result.

[0050] Alternatively, as Figure 2 As shown, obtaining deformation monitoring data of each area in the target slope and determining the first warning result of each area in the target slope based on the deformation monitoring data of each area include the following steps: S210: Obtain an average displacement change rate of multiple first monitoring points in the deformation area, and determine a first area warning result of the deformation area according to the average displacement change rate of multiple first monitoring points in the deformation area.

[0051] Specifically, the position data collected at different time points at multiple first monitoring points set on the surface of the deformation area can be used to calculate the average displacement change rate of the multiple first monitoring points, which is expressed as follows: ; in, For the i The average displacement change rate of the first monitoring point, For the i The first monitoring point t The displacement change per day, Δ t It is the number of days from the current day to the previous n days. n can be 3, 4, 5, etc. according to the actual situation.

[0052] Specifically, the judgment rules for the first area warning result are: normal: ; blue: ; yellow: ; orange: ; red: ; in, For the i The average displacement change rate of the first monitoring point, M is the total number of monitoring points within the deformation area, I (⋅) is the indicator function. When the condition is met, I (⋅)=1, otherwise I (⋅)=0; is the preset percentage, where ; ~ is the displacement rate threshold, > > The specific data is determined based on many factors such as geological conditions, slope types, engineering experience, and statistical analysis of monitoring data.

[0053] S220: Obtain an average displacement change rate of multiple second monitoring points in the deformation area, and determine a second area warning result of the deformation area according to the average displacement change rate of the multiple second monitoring points in the deformation area.

[0054] Specifically, for the position (or stress) data collected at different time points at multiple second monitoring points set underground in the deformation area, the average displacement (or stress) change rate of the multiple second monitoring points can be calculated, and the expression is as follows: ; in, For the j The average displacement (or stress) change rate of the second monitoring point, For the j The second monitoring point t The displacement (or stress) change per day, Δ t It is the number of days from the current day to the previous n days. n can be 3, 4, 5, etc. depending on the actual situation.

[0055] Specifically, the judgment rules for the second area warning result are: normal: ; blue: ; yellow: ; orange: ; red: ; in, For the j The average displacement (or stress) change rate of the second monitoring point, M is the total number of monitoring points within the deformation area, I (⋅) is the indicator function. When the condition is met, I (⋅)=1, otherwise I (⋅)=0; is the preset percentage, where ; ~ is the displacement (or stress) rate threshold of deep deformation (or stress).

[0056] S230: Determine a first early warning result of the deformation region according to the first early warning result of the deformation region and the second early warning result of the deformation region.

[0057] Specifically, the higher one of the first deformation region warning result and the second deformation region warning result may be taken as the first warning result for the deformation region.

[0058] For example, if the warning result of the first deformation area is W1, and the warning result of the second deformation area is W2, the warning levels from low to high are normal (marked as 0), blue (marked as 1), yellow (marked as 2), orange (marked as 3), and red (marked as 4), and the first warning result of the deformation area W0=max{W1, W2}.

[0059] S240: Obtain displacement changes of each third monitoring point in the non-deformation area, and determine a first non-deformation area warning result of the non-deformation area according to an average value of the displacement changes of each third monitoring point in the non-deformation area.

[0060] Specifically, assuming that p The average displacement of the third monitoring point in n days before today is , the average displacement from n+1 days before today to n+n days before today is , the difference between the two , that is, p The average displacement change of the third monitoring point is .

[0061] Specifically, the judgment rule for the warning result of the first non-deformation area is: normal: ; blue: ; yellow: ; orange: ; red: ; in, M is the total number of monitoring points in the non-deformed area, which is the same as the total number of monitoring points in the deformed area. ~ is a percentage, where < < < ; is the displacement threshold. In one embodiment, If the target slope surface deformation monitoring error is greater than the slope monitoring error, then 3mm is acceptable.

[0062] S250: Obtain the displacement (or stress) change of each fourth monitoring point in the non-deformation area, and determine a second non-deformation area warning result of the non-deformation area according to the displacement (or stress) change value of each fourth monitoring point in the non-deformation area.

[0063] Specifically, assuming that q The average displacement (or stress) of the third monitoring point in the n days before today is , the average displacement (or stress) from n+1 days before today to n+n days before today is , the difference between the two , that is, q The displacement change (or stress) value of the third monitoring point is .

[0064] Specifically, the judgment rule for the warning result of the first non-deformation area is: normal: ; blue: ; yellow: ; orange: ; red: ; in, M is the total number of monitoring points in the non-deformed area, which is the same as the total number of monitoring points in the deformed area. ~ is a percentage, where < < < ; is the deep displacement (or stress) threshold.

[0065] S260: Determine a first warning result for the non-deformation region according to the first warning result for the non-deformation region and the second warning result for the non-deformation region.

[0066] Specifically, the higher one of the first non-deformation region early warning result and the second non-deformation region early warning result may be taken as the first early warning result for the non-deformation region.

[0067] In this optional embodiment, different methods are used to calculate the displacement changes of monitoring points in the deformed area and non-deformed area of ​​the target slope, and the surface and underground of the area are monitored separately to accurately determine the first warning results of different areas.

[0068] Optionally, the radar monitoring device is used to determine the measured displacement rate, displacement duration and displacement area of ​​the target slope based on the radar data of the target slope, and compare the measured displacement rate, displacement duration and displacement area of ​​the target slope with the corresponding warning threshold, and determine a second warning result according to the comparison result; as shown in Table 1, Table 1 provides a radar threshold warning rule, the threshold corresponding to the displacement rate is the rate threshold, the threshold corresponding to the displacement area is the area threshold, and the threshold corresponding to the displacement duration is the time threshold.

[0069] Table 1 ; In Table 1, the short-term rate threshold is the rate threshold corresponding to the displacement rate in hours, and the long-term rate threshold is the rate threshold corresponding to the displacement rate in days; o1 to o8 are the displacement rate thresholds, s1 to s4 are the displacement area thresholds, and t1 to t4 are the displacement time thresholds. The specific data are determined by comprehensively considering multiple factors such as geological conditions, slope type, engineering experience, and statistical analysis of monitoring data.

[0070] Optionally, the image monitoring device is used to determine the number of landslides and the amount of landslides of the target slope based on the image data of the target slope, and determine a third warning result based on the number of landslides and the amount of landslides of the target slope.

[0071] Specifically, when the target slope is monitored using high-definition infrared video, the number of landslides and the amount of landslides on the target slope are monitored 24 hours a day, and the number of daily landslides or the amount of a single landslide is compared with the corresponding threshold. The third warning results are divided into four levels from low to high: blue, yellow, orange, and red.

[0072] When the single landslide volume 0<CL≤c1 or the daily landslide frequency 0<CC≤c4, a blue warning will be issued; When the single landslide volume c1<CL≤c2 or the daily landslide frequency c4<CC≤c5, a yellow warning is issued; When the single landslide volume c2<CL≤c3 or the daily landslide frequency c5<CC≤c6, an orange warning is issued; When the single landslide volume CL≥c3 or the daily landslide frequency CC≥c6, a red alert will be issued.

[0073] c1~c3 are the landslide volume thresholds, c4~c6 are the landslide frequency thresholds, CL is the single landslide volume, and CC is the daily landslide frequency. The specific data are determined based on a comprehensive consideration of geological conditions, slope types, engineering experience, and statistical analysis of monitoring data.

[0074] Optionally, the earthquake monitoring device is used to determine the fourth early warning result based on the earthquake acceleration monitoring value of the target slope.

[0075] Specifically, when the target slope is monitored for strong earthquakes, the earthquake acceleration measurement value is compared with the strong earthquake threshold. As long as a strong earthquake occurs, a red warning will be issued, and normal will be reported if no strong earthquake occurs.

[0076] Optionally, the environmental monitoring device is used to determine a fifth warning result based on the rainfall on the target slope.

[0077] Specifically, when the target slope monitors rainfall, the daily rainfall is compared with the rainfall warning standard, and the fifth warning results have four warning levels from low to high: blue, yellow, orange, and red.

[0078] According to the rainfall intensity standard of my country's meteorological department, when the rainfall within 12 hours is 30mm>s≥15mm or the rainfall within 24 hours is 50mm>s≥25mm, it is considered heavy rain and a blue warning is issued, where s is the rainfall.

[0079] When the rainfall within 12 hours is 70mm>s≥30mm or the rainfall within 24 hours is 100mm>s≥50mm, it is considered heavy rain and a yellow warning is issued.

[0080] When the rainfall in 12 hours is 140mm≥s≥70mm or the rainfall in 24 hours is 250mm≥s≥100mm, it is considered as heavy rain and an orange warning is issued.

[0081] When the rainfall s>140mm within 12 hours or the rainfall s>250mm within 24 hours, it is considered as heavy rain and a red alert is issued.

[0082] In this optional embodiment, the image data, radar data, seismic data, environmental rainfall, etc. of the target slope are analyzed separately to determine accurate warning results to achieve comprehensive slope warning.

[0083] The following provides a specific implementation method of slope warning, such as Figure 3 As shown, the following steps are included: S310: Collect geological survey reports for the target slope area to understand information such as stratum lithology, geological structure, and the physical and mechanical properties of the rock and soil. Consult regional geological maps and topographic maps to understand geological conditions such as the slope's degree of weathering and joint development. Record the location, strike, width, depth, and other geometric features of ditches and ridges. Investigate cracks and faults to determine their location, length, width, occurrence (strike, dip, inclination), and filling conditions.

[0084] S320: Regional division of the target slope.

[0085] 1) Division based on geological conditions: In areas where cracks are densely developed, the integrity of the rock and soil is poor. Areas with similar crack development levels can be divided into a zone based on the density and connectivity of the cracks. Faults will destroy the continuity of the rock and soil, and the faults and their affected zones can be divided into an independent zone.

[0086] 2) Division based on topography: The valley and its affected area are divided into an independent area; the ridge is usually stress concentrated and is greatly affected by weathering and erosion. The ridge and the surrounding area within a certain range can be divided into a zone; 3) Division based on unstable factors: Based on historical landslide data and potential sliding surfaces, high-risk landslide areas are divided; based on the distribution of dangerous rock masses and stability analysis, high-risk collapse areas are divided.

[0087] 4) Depth area division: The depth of the landslide is divided into different depths according to the degree of weathering of the rock and soil, including full weathering, strong weathering, moderate weathering and slight weathering. In combination with geological conditions, the depth of the landslide area is generally divided to the boundary between the deformation zone and the stable zone.

[0088] According to the above principles, the target slope is divided into several areas. Each area has a surface boundary and depth. The volume of each area is calculated in theory.

[0089] S330: Setting monitoring points.

[0090] Based on the slope monitoring layout, determine the location and number of monitoring points within each area. When using radar for remote slope monitoring, the radar acquires displacement data from the slope surface and generates a displacement field map. Key points within this displacement field map are extracted and used as monitoring points within each area. By tracking their radial displacement and velocity information, early warnings can be calculated. If radar equipment is unavailable, a total station can be used, employing a non-optical prism monitoring method (i.e., using the total station to directly aim at fixed points on the slope). This method can also obtain displacement information for measuring points within each slope area.

The management and control level is departmental, and the department head or designated personnel in specific positions are responsible for management and control; necessary management and control measures should be taken for the risk, and supervision and implementation should be strengthened.

[0094] (2) When the warning result is yellow, the risk level is general risk, the emergency plan is that the possibility of slope instability is small, or the risk loss and impact are small, and the risk is assessed to be acceptable and tolerable; the control level is departmental level, and is controlled by the department head; necessary control measures should be taken for the risk, and supervision and implementation should be strengthened to minimize the risk consequences.

[0095] (3) When the warning result is orange, the risk level is high risk, the emergency plan is that the possibility of slope instability is high, or the risk loss and impact are high, and the risk is assessed to be conditionally acceptable; the management and control level is company level, and is managed by the company's main person in charge; a risk management and control file must be established, and necessary management and control measures should be taken to reduce the risk level as much as possible. Only after taking necessary emergency response measures can work be resumed in an orderly manner.

[0096] (4) When the warning result is red, the risk level is major risk, the emergency plan is that there is a high possibility of bank instability, the risk loss and impact are large, and the risk is assessed to be unacceptable; the control level is government level, and the company's main person in charge consults with the local government department in charge to establish a working group with the relevant government person in charge as the group leader and the persons in charge of the affected power stations, villages and towns, and production enterprises in the cascade basin as members. The working group is responsible for the management and control; rectification must be carried out immediately, and operations must be stopped until the risk level is reduced. Work can only be resumed.
