AI Technical Summary
Existing technologies for predicting anchorage deformation in rock slope excavation lack in-depth extraction of spatial trajectory evolution and structural center of gravity migration processes among multiple layers of information. This results in insufficient accuracy in identifying the non-equilibrium distribution of stress field and structural offset paths, making it difficult to reflect the dynamic evolution characteristics under complex scenarios in a timely manner. Consequently, this leads to deviations in anchorage response path identification and affects stability assessment during construction.
By acquiring profile density maps, lithological classification maps, and construction progress maps, we can analyze the changes in rock block volume and the shift of the center of gravity. Combined with anchorage layout maps and stress monitoring maps, we can extract the locational relationship of stress anomaly distribution, screen the segments associated with offset paths and stress boundaries, analyze crack changes and joint dip angles, and screen areas of shear deformation rate changes to achieve prediction of rock slope anchorage deformation trends.
It enhances the ability to identify spatial continuity and the resolution of temporal response, enabling dynamic judgment of structural deformation paths and extension directions, thereby improving the accuracy and stability of predicting anchorage deformation during excavation of high rock slopes.

Common methods include trend analysis based on historical monitoring data, analytical method based on geophysical parameters, finite element numerical analysis method based on continuum mechanics theory and its iterative optimization method, etc. Generally, by setting initial boundary conditions and material constitutive relations, displacement or stress field is solved in combination with field monitoring data, and then the deformation state of future specific space-time nodes is derived. Among them, the traditional rock high slope excavation anchoring deformation prediction refers to predicting the tensile, shear slip or displacement variation of rock mass structure caused by stress change, hydrological condition disturbance, etc. during the blasting, excavation and anchoring construction of rock high and steep slope, using methods such as empirical formula fitting, elastoplastic constitutive model calculation, difference method and finite element discrete modeling method. The content usually includes rock mass classification, structure surface trend angle, anchor length and spacing, load boundary condition, blasting vibration velocity measurement in the deformation prediction report, and regression fitting or model iteration are combined with the measured deformation monitoring data to complete the prediction analysis.
[0003] The existing technology focuses on model parameter setting and monitoring quantity regression analysis in the process of structural deformation response identification, lacks deep extraction of spatial trajectory evolution and structure gravity migration process among multi-layer information, and shows response delay and insufficient positioning accuracy when involving stress field non-uniform distribution and structure displacement path identification. It is difficult to construct an abnormal distribution framework with spatial extension at the initial stage of deformation anomaly, especially in the face of unstable continuous profile deformation trend, crack closure and joint angle dramatic fluctuation, etc. The prediction result cannot timely reflect the dynamic evolution characteristics of the key area, causing the accumulation of anchoring response path identification deviation, and it is difficult to support the stability dynamic evaluation in the process of partition regulation and continuous construction.

S3: Based on the stress anomaly distribution area position corresponding relationship, the intersection graph line area is extracted, it is judged whether the slope structure offset direction and the stress change area boundary direction remain consistent in the extension process, the trajectory points of continuous spatial direction are connected, the spatial angle change and distance trend on the layer are analyzed in sections, the trajectory paragraphs continuously coinciding with the offset direction and the boundary trend are extracted, and the offset path and stress boundary associated paragraphs are obtained; S4: Based on the offset path and stress boundary associated paragraphs, the shear deformation change trend, joint dip angle change amplitude and fracture opening and closing change characteristics of the surrounding monitoring points are read along the path direction, whether the fluctuation directions of adjacent regions are consistent is compared, the profile area with continuous abnormal change is screened, and the continuous abnormal trend distribution content is obtained according to the layer index corresponding number and position area; S5: Based on the continuous abnormal trend distribution content, the shear deformation rate change amplitude concentrated section in the monitoring parameter time sequence is extracted, the direction continuation characteristics in the adjacent time window are analyzed, the corresponding construction time sequence node and response change occurrence sequence are analyzed, the time distribution situation is analyzed through the trend line change amplitude, the position content maintaining the extension trend in the spatial direction is extracted, and the rock slope anchoring deformation trend prediction result is obtained.
[0023] The slope structure migration path change characteristics include rock mass volume change trend, rock mass quality spatial difference, and slope gravity center transfer trajectory. The stress anomaly distribution area position corresponding relationship includes non-equilibrium section position, layer number corresponding area, stress anomaly point and displacement direction response relationship.

The continuous abnormal trend distribution content includes shear deformation abnormal profile, joint dip angle dramatic change area, and fracture opening and closing fluctuation concentrated area. The rock slope anchoring deformation trend prediction result includes shear deformation rate change concentrated section, construction time sequence and response change sequence, and spatial direction extension trend position.
[0024] Please refer to Figure 2 , and the specific steps of S1 are as follows: S101: Obtain the profile density graph, lithology division graph and construction progress graph, extract the rock mass volume and density value of the stage profile coordinate range, configure the quality data frame corresponding to the area, compare the quality distribution change of the stage, extract the regional quality state with time, and obtain the rock mass stage quality evolution sequence; The layer content in the profile density map, the lithology division map and the construction progress map needs to read the coordinate boundary information, the layer number and the legend mark corresponding to each profile position in the sheet in sequence, convert the sheet frame of each stage profile map in the sheet into a spatial coordinate range, combine the actual coordinate value range calibrated according to the scale in the sheet, extract the graphic element area within the coordinate boundary corresponding to each profile, mark the relationship between the color shown by different regions and the corresponding density value according to the color distribution in the density map, divide the rock block unit density value covered by each coordinate region according to the color distribution in the density map, and then aggregate the pixels in the same coordinate range into a unit region. The area of the unit region is converted into an area value according to the scale of the drawing, and the height is determined according to the profile depth information, and then the three-dimensional volume is derived. The rock block volume is estimated by multiplying the area value of the divided region by the vertical extension height. If the area of a region is 15x10 proportional grid units, the height is 6 grids, then the converted volume is 900 volume units, and the density value of the corresponding region is 2.65 units of mass, then the mass data of the region is 2385 units of mass. The area and matching density of all profile maps need to be read in this way, and the mass value is calculated item by item to form the mass data frame under the profile stage. When processing the construction progress map of each stage, the stage identifier and boundary range marked in the sheet need to be retrieved, the mass data frames of the same coordinate region in each stage are compared, the mass values of the region in different stages are compared horizontally, the change difference and change direction are extracted, and it is judged whether the difference is an increment or a decrement. If the mass of a region is 2500 in stage one and 2150 in stage two, the difference is -350, which represents a decrease in mass in the later stage. According to the sheet annotation order, the change trend of each stage region is sorted in sequence to obtain the mass change state sequence of multiple regions with the progress of the stage. The mass change state set is formed by rearranging the stage sequence, and the mass change state corresponding to all regions is connected in sequence according to the coordinate index, so that the mass change path of the region in the progress of each stage is extracted, and the stage mass evolution sequence of the rock mass is obtained.
[0025] S102: Based on the stage mass evolution sequence of the rock mass, extract the stage boundary coordinate point, compare the spatial positions of the same numbered points, judge the direction change, extract the trajectory data of the continuous position offset, divide the path according to the direction change trend, and obtain the structure position direction migration path set; First, the coordinate points corresponding to the profile boundary positions in each stage are extracted and indexed in a numbered manner. For each numbered point, the coordinate position changes in different stages are read segment by segment. By reading the horizontal and vertical displacement values of the coordinate points, the offset direction of the point is identified and judged. For example, the coordinates of numbered point P1 in three stages are (128, 95), (130, 98), and (132, 102). It is judged that there is a shift in the longitudinal and horizontal coordinates, and it can be concluded that it is shifted to the right and up. Then, the coordinate points of the same number in multiple stages are connected in order to form a trajectory path. Next, the above coordinate comparison and direction judgment operations are performed on all numbered points. Points with continuous shift characteristics are grouped into the same trajectory group. If multiple points move in the same direction during stage advancement, it indicates that they have consistent direction. Record the trajectory set number and spatial position coordinates. These trajectories are divided into different path clusters based on direction changes. If the angle changes in multiple trajectories are within 5 degrees, they can be grouped into a consistent direction path. For example, points numbered P3, P4, and P5 change direction to the east and north in three stages, and the direction angle fluctuation is not more than 5 degrees. They can be grouped into the same trajectory direction path set. In this process, the starting point and end point coordinates of each trajectory need to be identified. The trend of each path in the path set is compared, and the direction of each sub-path in the path set is classified. Finally, the paths are divided by number, and the contents of each path cluster are aggregated to form a unified set. The number, extension direction, and corresponding coordinate point set of each path are output to obtain the structure position direction migration path set.
[0026] S103: Call the structure position direction migration path set, retrieve the center point position in the path, compare the transfer direction and path trend, arrange the direction consistent transfer segment as a continuous path in coordinate order, and obtain the slope structure migration path change characteristics; First, read all the coordinate points of each path in the path set, and extract the centroid position of the area enclosed by the path. The centroid coordinates are taken as the spatial barycenter of the path. The extraction process is performed on each path in turn. For example, the path with path number T01 has coordinate points (118, 92), (121, 94), and (125, 98). The center point is calculated as (121.3, 94.6). After recording the barycenter coordinates, the direction of the path from the starting point to the ending point is annotated. The relative position change direction of the barycenter is confirmed. It is judged whether the change direction is consistent with the original direction of the path. If the directions are consistent, the transfer segment information is retained, and the path number and trend identification are recorded. Further, the transfer segments with consistent directions are sorted according to the order of the barycenter coordinates on the coordinate axis. The continuous sorting results from the starting path to the ending path are obtained. If path numbers T05, T06, and T07 show a monotonic increasing trend in the barycenter coordinates, it indicates that the spatial arrangement has continuity. The connection relationship of the paths in this direction is further expanded. If there is a reverse path direction in the middle, the path sequence expansion is interrupted. This operation is performed on each initial path for multiple rounds of direction consistency comparison and connectivity judgment. The coordinate range covered by each continuous path and the connection order number are annotated in the final output. Finally, the slope structure migration path change characteristics are obtained.
[0027] Please refer to Figure 3 The specific steps of S2 are as follows: S201: Based on the slope structure migration path change characteristics, extract the layout position and axial force time sequence change information corresponding to each group of anchor rods in the anchor layout map and stress monitoring data map. According to the layout number, extract the change trend in turn. Select the number section that continuously presents a linear trend turning point to obtain the axial force change trend annotation sequence. First, locate the layer number corresponding to each path, extract all anchor layout number information covering the layer in the anchor layout map, and record the three-dimensional coordinate layout point for each number. Match the corresponding number position with the number axial force time series curve in the axial force monitoring data map. Segment the axial force change trend sequence under each anchor number, and use the numerical difference sequence in each time period as the basis for judging the change trend. Then, perform directional consistency judgment on each segment of the axial force sequence. If the axial force growth direction changes from positive to negative, or from negative to positive in three or more consecutive monitoring points, record the start and end numbers of the change position and mark them as a trend turning section in the order of the layout numbers. If there are multiple monotonic increasing segments in a certain number interval, such as A15 to A23, that turn into decreasing segments, record it as a linear turning segment. Perform this screening operation on all layout number sequences, extract and label the number sections that meet the turning conditions, and associate the three-dimensional layout position corresponding to the number based on the layout map coordinates. Finally, construct a number and change state comparison sequence table, and distinguish the number segments with different direction turning. Establish a symbol sequence representing the turning direction, such as assigning a negative sign to a section that turns from rising to falling, and vice versa. Get the axial force change trend annotation sequence.
[0028] S202: Based on the axial force change trend annotation sequence, extract the number point coordinate position and compare it with the adjacent area displacement response direction to judge whether the direction is consistent. Screen the layout points with direction deviation, extract the spatial distribution information, and get the direction response deviation coordinate set. Firstly, call each set of anchor rod layout number recorded therein, extract its three-dimensional coordinate information in order of number, in the process of extracting coordinates, the three-dimensional space position of all numbered points in the same layout section is aggregated to form the spatial layout point set corresponding to the layout path, and the displacement response direction information corresponding to the number is searched in the stress monitoring data graph, the direction information is compared with the response direction data of the adjacent two numbers before and after the numbered point, if the response direction change amount continuously remains in single direction change, it is determined that the direction is consistent, if the response direction change sign is different from that of the adjacent point at any numbered point, it is determined that the direction deviates, record the numbered point and its spatial coordinate information, and record its layer index number at the same time, in the specific execution, take a numbered point B12 as an example, its displacement response direction is inclined to the lower left, compared with adjacent numbered points B11 and B13, if the direction change sign changes, extract the three-dimensional coordinates of the point x=42.1, y=108.3, z=16.7, and record its layer number T07, at the same time, the point in the layout path is marked as a direction abnormal path point, after completing the direction consistency judgment of all numbered points, the spatial information aggregation operation is performed on all layout numbered points with direction deviation, the coordinate position is classified according to the layer index, and the numbered points are arranged in ascending order, finally the direction response deviation coordinate set is obtained.
[0029] S203: Based on the direction response deviation coordinate set, the index position in the layout graph layer is located, the coordinate range of the adjacent numbered area in the same layer is extracted, the continuous area is merged in order as a same response area, the area position corresponding layer coordinate is output, and the stress abnormal distribution area position corresponding relationship is obtained. Firstly, read the spatial coordinates and number information of each group of offset points in turn, match each number with the index position of the anchor point in the layout graph layer, locate the specific coordinate area of each offset number in the layer grid in the layout graph, sequentially determine the number value increment or decrement direction between adjacent numbers, if there is a continuous numbering relationship between adjacent numbers, and the coordinate position belongs to the same block or exists boundary contact in the layer grid, it is determined that the point group belongs to the same numbered area, for example, numbered P13, P14, P15 are horizontally distributed in layer T03, and the x-axis coordinate difference value is less than 2 meters, and the y-axis difference value is not more than 1 meter, it is determined that they are continuous numbers in the same area, and the numbered segment is recorded as a group of continuous numbered areas, then according to the coordinate value range of all points in the region, the maximum x, y value and minimum x, y value of the region are extracted, and the coordinate bounding box of the numbered region is established, then the operation is continued in the adjacent layer, the layers are classified according to the layer number, and the region division process of all offset numbered points is completed in turn, finally, multiple numbered points with continuous numbering, close coordinates and consistent layers are aggregated into independent response areas, the layer number and coordinate bounding box range are output, and the stress abnormal distribution area position corresponding relationship is obtained.
[0030] Referring to Figure 4 The specific steps of S3 are as follows: S301: Based on the stress anomaly distribution area position corresponding relationship, the intersection area of the slope structure trajectory and the stress boundary line segment in the layer is extracted, the structure deflection direction and the boundary extension direction vector at the intersection point are compared, it is judged whether the direction consistency is possessed, the intersection line segment with consistent direction is extracted, and the direction consistent intersection paragraph set is obtained; Firstly, the coordinate sequence of each slope structure trajectory line segment is retrieved from the layout layer, and the annotated stress boundary line segment set in the corresponding layer is extracted synchronously. By means of coordinate interval comparison, the intersection area with coordinate overlap or approximate coincidence between the two types of line segments is identified. The intersection point coordinates are obtained in the intersection area, and the strike vector of the trajectory segment at the intersection point and the extension vector of the boundary line segment are located. Further, the angle direction of the two vectors is judged. If the angle between the two vectors is less than the specified threshold angle and the direction cosine value is greater than the direction consistency judgment threshold, it is indicated that the trajectory segment and the boundary segment at the intersection point exist direction consistency, for example, the direction of the trajectory segment at the intersection point is north by east 10 degrees, and the direction of the stress boundary line is north by east 12 degrees, the direction angle is 2 degrees, and the direction consistency judgment threshold is set to 5 degrees. Therefore, the intersection point satisfies the direction consistency condition, and the trajectory segment and the boundary segment corresponding to the intersection point are jointly regarded as the direction consistent intersection line segment, and the number index and the layer number thereof are recorded. After traversing all the intersection areas, the line segment set satisfying the direction consistency judgment is merged and numbered, and is arranged into a unified data frame output, and the direction consistent intersection paragraph set is obtained.
[0031] S302: Based on the direction consistent intersection paragraph set, the continuous trajectory points on the coordinate extraction layer are extracted, the trajectory nodes continuously consistent in spatial distribution direction are screened, the points before and after the direction deflection of the trajectory line segment are compared, the line segment without direction deflection is identified, and the spatial direction continuous trajectory set is obtained; First, the trajectory point sequence associated with each trajectory segment is extracted from the cross paragraph, and the coordinates in the layer are sequentially sorted. The sorted trajectory points are arranged in order according to the number to form an initial trajectory path set. In the set, the directional vector between any two adjacent trajectory points is calculated according to the coordinate difference. Three consecutive points form two line segments. The direction deflection is identified by calculating the included angle of the two line segments. If the included angle of the two directional vectors is less than the spatial deflection threshold, it is considered that the two trajectory segments have not deflected in the direction. The trajectory points here maintain continuity in the spatial distribution direction. For example, if the included angle of the two line segments formed by the trajectory points P1, P2 and P3 is 4 degrees and the deflection threshold is 5 degrees, P2 is retained as a direction continuous point. If the included angle is 6 degrees, the point is excluded. All adjacent points are subjected to the included angle judgment operation. The trajectory points that meet the spatial direction consistency condition are filtered out in each trajectory. Finally, the trajectory segment set with continuous direction characteristics is output according to the trajectory number index, and the spatial direction continuous trajectory set is obtained.
[0032] S303: Call the spatial direction continuous trajectory set, intercept the spatial angle change and distance distribution range of the line segment presented in the layer, filter the segments consistent with the structure offset direction and stress boundary trend continuation, output the trajectory number and layer coordinate range, and obtain the offset path and stress boundary associated paragraph. First, the spatial vector parameter set formed by the start and end coordinate points of each line segment is extracted according to the trajectory number information in the trajectory set. The spatial angle change of each line segment is identified separately. In the identification process, the change of the included angle between the coordinates is used as the angle determination basis. The angle interval between the start point and the end point vector is extracted. The trajectory line segment directional vector is compared with the structure offset directional vector. When the trajectory line segment direction is within the angle offset range threshold and the direction is consistent, it is considered as a consistent segment. For example, in the northeast direction of the structure offset direction, if the angle vector of a certain trajectory line segment is less than 15 degrees with the offset direction and points to the northeast, it is judged that the line segment is a direction consistent segment. The start and end coordinates of the direction consistent line segment in the layer are extracted and the distance between each segment is calculated to construct the distance distribution sequence of each trajectory. Then, the stress boundary trend directional vector is introduced. If the trajectory line segment direction is consistent with the stress boundary trend vector within the included angle range, the trajectory line segment is considered as a line segment that meets the dual consistency conditions of the structure offset direction and the stress boundary trend. Finally, the trajectory number, layer coordinate range and direction attribute of the line segment are output to obtain the offset path and stress boundary associated paragraph.
[0033] Please refer to Figure 5 , the specific steps of S4 are: S401: Based on the offset path and stress boundary association paragraph, the shear deformation sequence of the monitoring point, the joint inclination range and the crack opening and closing state are extracted along the path direction, the direction scalar of the adjacent monitoring point in the parameter sequence is analyzed, the continuous response segment with consistent direction is screened, and the direction unified deformation segment set is obtained; First, index extraction is performed on each monitoring point in the path range, and the shear deformation sequence data, joint inclination range information and crack opening and closing state content of the corresponding monitoring point are called in the layer database. The displacement direction value of the shear deformation sequence is extracted in sequence, the joint inclination is formed into a change interval according to the angle difference between adjacent two points, and the crack state is positively or negatively identified by the gap width change direction between adjacent nodes. In the above three parameter data, the numbering section consistent with the coordinate arrangement order is extracted, and the direction uniformity judgment operation is performed on the direction vector of the continuous monitoring point in each path segment. In the judgment process, the direction vector pair between each adjacent two points is called to perform angle comparison operation. If the included angle is within the set threshold range, for example, less than 20 degrees, and the scalar is positive in the coordinate arrangement direction, it is determined that the directions are consistent. According to this standard, the monitoring point paragraphs in the whole path that meet the direction continuous state are screened, and the shear deformation value, joint inclination value and crack state change trend in the paragraph are recorded respectively. In the example, the shear deformation in a certain numbering segment (such as P101-P108) is southeast displacement, the joint inclination continuously increases from 25 degrees to 32 degrees, and the crack opening increases from 3.5mm to 4.2mm. The directions are consistent. Such segments can be classified into unified response sequence. In all path segments, this screening process is performed in turn, and after the extraction of each segment with consistent direction is completed, the direction unified deformation segment set is finally obtained.
[0034] S402: Based on the direction unified deformation segment set, the layer coordinate section where the segment is located is identified, the monitoring curve fluctuation pattern of the adjacent area is extracted, the response path offset position point is extracted at the continuous trend change node, the spatial connection relationship between the offset points is analyzed, and the continuous response segment positioning index is obtained. First, the coordinate analysis operation is performed on each segment corresponding to the layer number, the minimum rectangular area range covered by the segment in the layer file is extracted, and all monitoring point numbers in the range are listed as a candidate set, then the displacement response curve of the adjacent numbered points in the candidate set is called, the data points are extracted from the curve graph segment by segment, the trend nodes in the fluctuation form are identified by judging the number of positive and negative switching times of adjacent points in the value change direction, wherein if a numbered point has the same curve direction as the previous numbered point and the opposite curve direction as the next numbered point, it is a trend change node, further, the offset position points in the path direction are extracted at these nodes, the offset points should satisfy the condition that the coordinate increment direction changes or the adjacent coordinate increment is negative, then the coordinates between all offset points are combined, the adjacent offset points are connected in ascending order of number, the distance distribution of adjacent two points in horizontal and vertical directions is analyzed, if one of the horizontal direction difference and the vertical direction difference between the two points is zero, or the ratio of the two is an integer multiple of 1, it is considered that the two points have a spatial connection relationship, for example, in the example, if the offset points M105 and M106 are spaced 2.0 meters apart in the X direction and 0.0 meters apart in the Y direction, they are identified as continuous connection points, the connectivity of all offset points is judged in this way, and each offset path sequence with continuous connectivity is recorded in turn, the point position number in the path sequence is output as an index to form the unique positioning sequence of each deformation trend segment in the layer, and finally the continuous response segment positioning index is obtained.
[0035] S403: Based on the continuous response segment positioning index, match the numbered and coordinate area in the layer, filter the path response sequence with continuous change form under the same number, eliminate the points that do not form periodic segments, aggregate the index position and response direction information corresponding to the path sequence, and obtain the continuous abnormal trend distribution content; First, retrieve the layer file one by one according to the order of the index set, extract the coordinate point range corresponding to each number, and determine its spatial position in the monitoring area and the response path number group to which the number belongs. Multiple coordinate segments belonging to the same path number are grouped into a trajectory response sequence. Then, the displacement or shear deformation monitoring value is extracted in the response sequence according to the time sequence. For each sequence, a continuity judgment process is applied, that is, three consecutive points are taken as a judgment unit. If the change trend of the middle point in the unit and the adjacent two points show the same direction of monotonic change, it is recorded as a continuous trend segment. For example, the value corresponding to number P304 is 1.2, 1.5, and 1.8. It can be judged that the trend is increasing and belongs to the continuous change form path. If the trend direction switches repeatedly within three points, it is considered as a non-continuous segment, and the point number in the judgment sequence is removed. Further, in the continuous trend path obtained, it is identified whether it has periodic characteristics between adjacent segments. The judgment logic is: calculate the response amplitude difference between the trend segments and the number of continuous segments. If the amplitude difference fluctuation amplitude between different segments does not exceed the set threshold and the point number error in the trend period does not exceed the allowed range, it is considered that the path has periodic form. Otherwise, the segment number point is also removed. After removing all points without periodic characteristics, the remaining effective points are merged according to the path number. Through the coordinate backtracking of the number position, the spatial position of the layer is obtained, and the response trend direction of each point is counted. If more than 70% of the point trend direction vectors in a path segment are consistent, that is, they are all rising or falling, the segment is assigned the "consistent direction" attribute. Finally, the number index of each path segment and its direction trend value are combined to form a number and response direction pairing sequence, and the continuous abnormal trend distribution content is obtained.
[0036] Please refer to Figure 6 The specific steps of S5 are: S501: Based on the continuous abnormal trend distribution content, extract the section with concentrated change amplitude in the shear deformation rate sequence, call the index corresponding to the monitoring time sequence, analyze the continuity of adjacent data points in the time axis direction, and filter the segments with direction maintaining state to obtain the shear rate continuous segment index. First, relying on the path paragraph and coordinate sequence labeled in the previous stage, the corresponding shear deformation rate sequence is retrieved from each paragraph, and the monitoring point number in each paragraph is corresponded to the rate value point recorded in the rate curve. The value segment with obvious change amplitude is extracted by point-by-point traversal. In the execution process, the monitoring point number is arranged in ascending order, and the amplitude difference operation is performed with a sliding window of five consecutive points. The change value of the current point and the previous period is calculated. If the continuous three difference values are greater than the preset change threshold, such as 0.08 mm / h, it is marked as a region with obvious change. In actual application, the shear rate of numbers P211~P215 is 0.10, 0.21, 0.34, 0.43, and 0.51 respectively, which can be judged as a region with obvious rate increasing trend. Then, the monitoring time axis index of the data segment is located, the index numbers of adjacent points are extracted in chronological order, the time stamps are read in turn, and whether the adjacent time intervals are equal is calculated. The method for judging continuity is: if the time difference remains fixed within the allowable error range, such as the time interval is set to 3 hours, the error is allowed ±0.2 hours, then the current paragraph is continuous in time, otherwise the part of the data segment is excluded from the sequence. After continuity, it is further checked whether the rate change direction of adjacent monitoring points is consistent. The difference between the two adjacent points is used as the basis for judgment. If the three consecutive difference values are all positive or all negative, it is recorded as a direction maintaining state, otherwise it is marked as a direction reversal and not included in the subsequent sequence. For the numbered paragraph that meets the three conditions of amplitude significant jump, time continuity and direction consistency at the same time, the index number set corresponding to it in the original data set is generated as the labeled output, and the shear rate continuous segment index is finally obtained.
[0037] S502: Based on the shear rate continuous segment index, match the start and end time points of the segment with the construction time sequence node position in the layer, analyze the response delay distribution position point, filter the fragments with time difference structure from the previous segment, and obtain the construction response time delay path set; First, the start and end indexes of each numbered paragraph are extracted from the obtained continuation section, and the monitoring time corresponding to the indexes is retrieved. The start and end time points of each continuation segment are read in sequence index. Taking numbered P110 as an example, if the start index is 215 and the end index is 228, the corresponding times are the 45th period and the 51st period, respectively. The duration of the continuation segment is 6 unit periods. Then, the time period is compared with the construction time sequence node list recorded in the layer. The comparison content is segmented and positioned according to the corresponding relationship between the construction stage number and the spatial coordinates of the monitoring point. The coordinate range covered by each construction number in the layer is extracted by looking up the table. The coordinates corresponding to the continuation segment are matched with the coordinate interval of the construction drawing. The matching method is to determine whether the monitoring point belongs to the coordinate falls within the coordinate boundary range corresponding to the specified construction number. If there is a situation where the position falls in but the time does not coincide, it is marked as a response delay area. The start time of the segment and the start time of the construction number to which it belongs are continued to be extracted and the difference is calculated. If the difference exceeds the preset response delay threshold, such as 2 unit periods, the current segment number is recorded as a response delay segment. This operation is performed for each detection point segment to obtain a set of segments with time offset phenomena. Then, all monitoring points marked as delay segments are summarized and intersected with the original path segment to extract the numbered chain that still maintains trajectory continuity as the subsequent analysis object to obtain the construction response time delay path set.
[0038] S503: Call the construction response time delay path set, aggregate the path corresponding spatial coordinate point sequence, extract the path segment with consistent direction according to coordinate sorting, exclude the segment with direction jump, get the rock slope anchoring deformation trend prediction result according to the trajectory continuity and position trend maintaining relationship; First, all path segments on the coordinate point set are extracted from the delay path set according to the number, the spatial position coordinates of the monitoring points in each segment are listed according to the path number, and these point sequence is sorted according to the longitudinal coordinate priority, horizontal coordinate sequence, so that the arrangement order is consistent with the actual space trend. After sorting, the direction extension consistency judgment process is entered, for each two vectors composed of three consecutive points in each path segment, the included angle of the two vectors in two-dimensional space is calculated, if the included angle value is not greater than 15 degrees, it is judged that the direction is consistent, otherwise it is judged that the direction has jumped. Taking path P503 as an example, the point sequence is A (102.1, 208.3), B (103.5, 209.2), C (105.4, 212.7), the angle of AB vector and BC vector is compared, if the angle is 9 degrees, the three points can be regarded as direction continuation consistent, if the angle is 24 degrees, it is regarded as direction jump. The angle threshold of 15 degrees is a preset angle threshold, which is selected based on the conventional amplitude change of displacement change in structure construction process. The selection method refers to the angle change characteristics in the relatively stable section of continuous shear rate change in historical data. The jump section is excluded from the path used for trend fitting. Then the trajectory continuity of each direction continuation path segment retained after screening is judged. The judgment standard is that the distance between any two adjacent points does not exceed the set coordinate interval threshold, for example, set to 3 meters. If there is a point distance in the path that exceeds this value, it is determined that the trajectory is discontinuous, and this section does not participate in trend extraction. Then, the trend extension analysis is performed on all coordinates in the continuous direction maintaining paragraph. Linear fitting is performed on the same direction segment to extract the direction trend of the overall path. Taking number P703 as an example, the fitting result slope is 0.75, indicating that the overall displacement trend develops in an approximate 45-degree direction. Combined with the segment information with trajectory continuity and direction stability, the prediction trend line is constructed, and the rock slope anchoring deformation trend prediction result is obtained.
