[0017] Embodiment 1, please refer to Figure 1 and Figure 2 The flexible slope support optimization design system described in the present embodiment comprises: A data acquisition module acquires dynamic data and image data of the slope surface based on a plurality of array sensors deployed on the slope surface, and transmits the dynamic data to a dynamic relational database; A instability model construction module connected with the data acquisition module is used to analyze the dynamic data to generate a instability model of the slope surface, and generate a stress analysis report of the slope surface based on the instability model; Support interference field module: connected with the instability model construction module, based on the stress analysis report to generate the support interference field, based on the support interference field and the instability model interaction to generate the optimization scheme of the flexible slope support; Visualization module: connected with the support interference field module, for visualizing display of the instability model and the optimization scheme of the flexible slope support; Further, at present, the optimization design of the flexible slope support engineering mainly relies on periodic artificial survey and static monitoring data of limited points, and the traditional optimization method is usually established on the basis of discrete, historical geological survey report and simplified mechanical model; Then, the prior art has some deficiencies, the traditional monitoring system can only provide isolated physical quantity measurement values, such as displacement or stress data of a single point, lacks the ability to effectively associate and fuse multi-source, heterogeneous monitoring data and environmental factors, and the understanding depth of the slope state is insufficient, which leads to that the data analysis stays on the surface phenomenon, cannot reveal the inherent mechanical mechanism and evolution process of the rock mass hidden behind the data, makes the judgment of the potential instability mode seriously depend on the personal experience of the engineers, and the objectivity and systematization are insufficient; meanwhile, the traditional support design scheme is usually fixed once determined, and it is difficult to be adjusted in real time according to the dynamic response of the slope under the action of the external environment; the optimization process is an offline, non-continuous static calculation, and a dynamic model capable of truly reflecting the interaction of the internal state of the slope and the propagation path of the instability risk cannot be constructed, so it is difficult to realize the accurate and active matching of the support structure and the slope instability process in time and space, which leads to that the support scheme may lack foresight and adaptability; The present application can capture the subtle changes of the slope state in real time through the continuous collection of dynamic data and image data by the multi-array sensors deployed on the slope surface and the efficient processing by the dynamic relational database, the instability model construction module can generate a comprehensive instability model by integrating multi-source data through the distributed event analysis unit and the node collaborative reasoning unit, and accurately reflect the stress state of the slope; the support interference field module can convert the stress analysis into an initial interference field by using the field mapping unit, and dynamically correct the parameters by interacting with the event analysis subunit through the dynamic field generator; the channel monitoring unit can monitor the data load and automatically generate anchor nails to ensure the stability of the support structure, the mechanism can automatically generate an optimization scheme based on the intelligent algorithm of rock mechanics principle, reduce the subjective error of manual design, improve the reliability and economy of the scheme, and the active monitoring and rapid intervention mechanism can greatly reduce the probability of slope instability accidents and improve the intelligent level of the flexible slope support; The characteristic extraction operator embedded with geotechnical mechanics prior knowledge is used to perform parallel calculation and correlation analysis on the dynamic data of time-space sequence and the environmental state vector, to generate relationship tuples with clear physical meaning. Then, the neural network model is used for structured packaging to form event data groups representing specific geotechnical mechanics processes. This process essentially completes the paradigm shift from low-dimensional numerical perception to high-dimensional situation understanding, and improves discrete physical observation values to structured knowledge units containing causal logic. Such knowledge units not only represent the changes of the mechanical state of the local area, but also provide rich standardized inputs for subsequent distributed collaborative reasoning and instability mode identification of the system through their inherent spatio-temporal correlation attributes, laying the foundation for the whole system cognitive decision-making.
[0018] In one embodiment, the data acquisition module comprises: A multi-array sensing unit is distributedly deployed on the surface and inside of the slope to collect dynamic data of the slope, and to generate multi-source time-series dynamic data by labeling the dynamic data with time stamps and three-dimensional geographic coordinates; An environmental monitoring unit is used to synchronously collect environmental state data of the environment where the slope is located; The dynamic data and the environmental state data are transmitted to a dynamic relational database to generate event data groups; Further, the multi-array sensing unit is composed of geological sensor arrays arranged on the surface and inside the slope, specifically including micro-electro-mechanical system (MEMS) tilt sensors, fiber bragg grating (FBG) strain sensors, and resistance-type soil pressure cells, etc. These sensors communicate through low-power wide-area network (LPWAN) protocols. The multi-array sensing unit collects dynamic data of the slope, including deformation data, stress-strain data, and groundwater dynamic data. Deformation data is obtained by global navigation satellite system (GNSS) receivers and MEMS tilt sensors, which measure the absolute displacement and inclination angle changes of the ground surface. The array of buried inclinometers monitors the horizontal displacement of the deep layer. Stress-strain data is measured by distributed FBG sensors, which measure the continuous strain field changes along the fiber path inside the rock-soil mass. Resistance-type or vibrating wire soil pressure cells record the contact stress at key interfaces. Groundwater dynamic data is monitored by a network of osmometers, which monitor the spatial and temporal distribution and fluctuations of pore water pressure, reflecting the influence of hydrological conditions on slope stability. Each sensing node is equipped with a global positioning system (GPS) module and a miniature high-precision clock chip, which can automatically add nanosecond-level time stamps from the Beidou satellite navigation system and centimeter-level three-dimensional geographic coordinates based on spatial interpolation algorithms to the data packets while collecting dynamic physical quantities such as vibration, displacement, and stress. This generates a multi-source time-series dynamic data stream with a unified spatiotemporal reference. The environmental monitoring unit integrates weather stations, soil moisture meters, and osmometers to continuously collect environmental state data such as precipitation, temperature, humidity, and pore water pressure. After preliminary filtering and compression by the edge computing gateway, all sensing data is transmitted to the cloud dynamic relational database via the 5G dedicated slice network. The dynamic relational database adopts a fusion architecture of time series database and spatial database. Through the built-in rule engine and stream processing platform, real-time spatiotemporal registration, correlation analysis, and feature extraction are performed on the injected heterogeneous data. Finally, event data groups with complete semantic information are generated, providing standardized data input for the upper analysis module.
[0019] In one embodiment, the step of transmitting dynamic data to the dynamic relational database to generate event data groups is: The dynamic relational database includes a real-time data caching unit, an environmental modulation unit, and a dynamic relationship construction unit. The real-time data caching unit receives multi-source time-series dynamic data in real time and stores it in the cache space by building multiple sub-databases. The environmental modulation unit receives environmental state data and converts it into an environmental state vector. The dynamic relationship construction unit includes a feature rule library, a relationship calculation sub-unit, and a structured event packaging unit. The feature rule library pre-stores feature extraction operators based on rock-soil mechanics principles and spatiotemporal correlation rules. The relationship calculation subunit continuously calls the feature extraction operator to perform parallel scanning and calculation on the multi-source time-series dynamic data and the environmental state vector, and generates a relationship tuple; The relationship tuple includes the multi-source time-series dynamic data, the environmental state vector, a relationship type identifier, and a relationship strength quantization value. The structured event packaging unit analyzes the relationship tuple through a neural network, and generates an event data group based on the spatiotemporal association rule and the relationship type identifier. Further, the generation of the event data group relies on a multi-level dynamic relationship type database architecture. The real-time data caching unit uses a distributed time series database such as InfluxDB as a core storage engine, and simultaneously constructs a Redis cluster as a high-speed cache sub-database. Through a streaming processing platform, the multi-source time-series dynamic data is received and temporarily cached at a high throughput. The environmental modulation unit converts the environmental state data into a numerical vector through feature engineering. Specifically, a hot encoding process is used to process discrete meteorological categories, and a normalization method is used to process continuous physical quantities. Finally, an environmental state vector with fixed dimensions is generated. The core of the dynamic relationship construction unit is a feature rule library, in which pre-stored feature extraction operators exist in the form of pre-compiled functions, such as a differential operator for calculating displacement rate changes, a spatial clustering operator for identifying strain sets, etc. The relationship calculation subunit is implemented based on the Apache Flink streaming processing engine. Through a parallel pipeline, these operators are continuously called to perform real-time scanning on the dynamic data and the environmental vector in the cache. The Pearson correlation coefficient algorithm is used to calculate the relationship strength, and a relationship tuple containing the original data segment, the relationship type identifier, and the quantized strength value is output. Based on the obtained relationship triple, a recurrent neural network model is used to identify the spatiotemporal pattern of the input relationship tuple sequence. When a feature sequence that meets a specific instability precursor is identified, the packaging process is triggered, and an event data group with complete semantic description is generated. For example, under the condition of continuous rainfall, when the system monitors that the pore water pressure in the slope region X increases from 30 kPa to 60 kPa within 6 hours, the surface displacement rate accelerates from 0.5 mm / day to 3.0 mm / day, and the strain value in the deep strain concentration area increases from 10 micro-strain to 25 micro-strain, the system identifies the coordinated evolution of these parameters in space and time through geotechnical mechanics operators: water pressure rise triggers deformation acceleration, and the strain concentration area completely coincides with the high-risk area. Based on this, a relationship tuple representing the "hydraulic-deformation-strain strong spatiotemporal coordination" is generated, and finally the neural network determines that the multi-parameter acceleration anomaly pattern meets the instability precursor characteristics, and a semantic event data group "rainfall-induced shallow slip instability precursor in region X" is packaged and generated.
[0020] In one embodiment, the instability model construction module includes: A slope digital model construction unit constructs a three-dimensional slope digital model based on dynamic data and image data. The distributed event analysis unit extracts the three-dimensional geographic coordinate distribution characteristics of the event data group, and dynamically generates an event analysis subunit based on the three-dimensional geographic coordinate distribution characteristics, which is used to receive and analyze the event data group to generate a local instability feature vector; The instability knowledge base unit pre-stores a set of instability mode rules based on the principles of geotechnical mechanics, and the set of instability mode rules is used to define the mapping relationship between different combinations of local instability feature vectors and potential instability modes; The node collaborative reasoning unit is connected with each event analysis subunit and the instability knowledge base unit, performs collaborative reasoning on the local instability feature vectors, and synthesizes an instability model describing the state of slope stability; Based on the instability model, a stress analysis report of the slope surface is generated; Further, the technical implementation of the instability model construction module starts from the slope digital model construction unit, which establishes a three-dimensional geological entity model with centimeter-level precision by fusing laser point cloud scanning data and multi-view oblique photogrammetry images, and maps the geotechnical mechanics parameters as additional attributes to the model grid elements; The distributed event analysis unit dynamically instantiates lightweight edge computing nodes as event analysis subunits at the corresponding positions of the slope digital model according to the spatial coordinate information of the event data group. Each subunit analyzes the local event data group through the built-in feature extraction algorithm, and quantitatively generates a local instability feature vector containing dimensions such as displacement acceleration, strain energy density, and water coupling coefficient; The instability knowledge base unit adopts an expert system architecture, and its set of instability mode rules defines the triggering conditions of various instability modes in the form of production rules, for example, when the combination of feature vectors simultaneously satisfies local shear strain, displacement acceleration index exceeds the threshold value, and is spatially coupled with a high-porosity water pressure zone, the circular arc sliding mode rule is activated; The node collaborative reasoning unit normalizes the feature vectors output by each subunit through a spatio-temporal alignment engine, constructs a topological network with analysis nodes as vertices and spatio-temporal correlation strength as edges using a graph neural network algorithm, and realizes feature propagation and aggregation through a multi-layer message passing mechanism. Finally, the fused global features are matched with the instability knowledge base, and an instability model containing potential sliding surface geometric parameters, safety factor field distribution, and stress-strain cloud diagram is output, and a detailed stress analysis report is generated accordingly.
[0021] In one embodiment, the step of connecting with each event analysis subunit and the instability knowledge base unit, performing collaborative reasoning on the local instability feature vectors, and synthesizing an instability model describing the state of slope stability is as follows: The node collaborative reasoning unit receives the local instability feature vectors from each event analysis subunit and performs spatio-temporal alignment processing on all local instability feature vectors; The converged local instability feature vector set is matched with the instability mode rule set in the instability knowledge base unit, a corresponding potential instability mode is activated by calculating the matching degree of the feature vector and the instability mode rule set; Based on the three-dimensional geographic coordinates in the local instability feature vector, the correlation strength between local instability features at different positions is analyzed, and a correlation network representing the instability propagation path is constructed with each event analysis subunit as a node and the correlation strength as an edge. Combined with the activated potential instability mode and the correlation network, a weighted fusion algorithm is used to synthesize the instability model of the slope; Based on the instability model, a stress analysis report of the slope surface is generated, including potential sliding surface geometric parameters, safety factor distribution, stress-strain field data, support resistance requirement distribution, and dynamic evolution prediction. Further, the node collaborative inference unit first starts the space-time alignment engine to standardize the local instability feature vectors uploaded by the distributed event analysis unit; the engine uses the dynamic time warping algorithm to eliminate the time phase differences of each sensor data stream, and simultaneously maps the feature vectors of discrete coordinates to a unified three-dimensional grid node through the Kriging space interpolation method, to establish a feature vector matrix with space-time consistency. In the rule matching stage, the node collaborative inference unit matches the local instability feature vectors processed by the space-time alignment with the pre-stored instability mode rule set in the instability knowledge base unit. This matching process is implemented through a multi-level calculation framework. First, the matching core uses a vector similarity measurement algorithm, specifically to calculate the cosine similarity between each local instability feature vector and the pre-defined standard instability mode feature vector in the rule set, and generates an initial matching degree score. Then, the system calls the composite logical judgment conditions defined in the rule set. These conditions are scripts written based on the principles of rock mechanics, for example, a rule may require that the displacement acceleration index be greater than a set threshold, the strain concentration degree exceed a critical level, and the abnormal area overlap with a high-pore water pressure area in space, and other multiple Boolean conditions. The system will evaluate these conditions one by one and make a weighted correction to the initial matching degree to generate a potential instability mode. Based on the three-dimensional geographic coordinates in the local instability feature vector and the generated potential instability mode, the system calculates the statistical dependence of feature vectors at different positions through the mutual information entropy algorithm, quantifies the spatial correlation strength by combining the gravity model, and constructs a directed graph network with the event analysis subunit as the node and the spatial correlation strength as the edge. This network accurately represents the propagation path of the instability risk. The system integrates the activated instability mode and the correlation network through a multi-stage fusion process. First, a dynamic weight distribution mechanism is used to calculate a comprehensive weight coefficient based on the confidence value obtained by each instability mode in the rule matching stage and the topological centrality index of the mode corresponding node in the correlation network. Then, a slope stability control equation is established based on the theory of rock plasticity mechanics, and the slope digital model is converted into a numerical calculation grid through finite element discretization. In the solving process, the system embeds the potential slip path analyzed by the correlation network into the iterative calculation as a nonlinear constraint condition, and uses the strength reduction method to cyclically adjust the shear strength parameters of the rock mass, to monitor the state change of the global stiffness matrix of the model in real time. When the system stiffness matrix shows singularity characteristics, it is determined that the slope has reached a critical instability state, and the spatial coordinate parameters and geometric morphological features of the three-dimensional slip surface are accurately output at this time. The system synchronously generates complete mechanical field data including safety factor contour map, plastic strain distribution, and principal stress direction, and generates an instability model. Based on this, a stress analysis report is generated, including the geometric parameters of the slip surface, safety factor distribution, stress-strain field, support resistance requirement, and dynamic evolution prediction.
[0022] In one embodiment, the support intervention field module comprises: a field mapping unit for receiving the force analysis report and mapping the support resistance demand distribution, potential slip surface geometric parameters and stress-strain field data in the report as an initial interference field covering on the instability model; a dynamic field generator for generating a dynamic field generator based on the corresponding position of the three-dimensional geographic coordinates of the event analysis subunit on the initial interference field and connecting with the event analysis subunit through a dynamic channel; an interactive engine for constructing a field model in the dynamic field generator, built-in optimization objective function, receiving the local instability feature vector from the event analysis subunit through the dynamic channel, and inputting the local instability feature vector into the optimization objective function to dynamically correct the parameters of the initial interference field through the iterative adjustment algorithm; a channel monitoring unit for continuously monitoring the real-time load of all dynamic channels, based on the preset super-fusion threshold to entity the dynamic channel, and generating the anchor nail of the initial interference field; obtaining the correction parameters of the initial interference field and the anchor nail to generate the support interference field, and discretizing the continuous support interference field into the spatial layout coordinates, force parameters and construction sequence of the flexible support member through the field streamline tracking technology; Further, the construction process of the initial interference field is a key step of converting abstract mechanical data into concrete spatial force field. The field mapping unit first analyzes the multi-dimensional data of the force analysis report, extracts the key parameters of the field strength, and converts the support resistance demand distribution into scalar field strength data. The geometric parameters of the potential slip surface are used to define the direction reference of the vector field, and the stress-strain field data are used as the basis input of the tensor field. In the specific implementation, the system converts the discrete support resistance demand data into continuous field strength distribution based on the three-dimensional grid structure of the instability model through spatial interpolation algorithm. This process uses the improved Kriging interpolation method, which not only considers the spatial distance relationship, but also introduces the geotechnical mechanical parameters as the collaborative variables to ensure that the field strength distribution conforms to the geomechanics law. For the establishment of the vector field, the system generates the field direction distribution covering the entire model by using the tangent direction of the potential slip surface as the main reference benchmark and combining with the principal stress direction data through the vector synthesis algorithm. In order to achieve the real coverage effect, the system uses the hierarchical mapping technology to first establish the two-dimensional field distribution on the surface of the instability model, and then extends to the depth direction according to the geological stratification data to form a three-dimensional field. The field parameters of each grid element are determined through weighted calculation, and the weight depends on the relative position of the element to the slip surface and its importance in the stress field. This depth-coupled mapping method ensures that the initial interference field is completely consistent with the instability model in geometry and mechanics, laying a solid foundation for subsequent dynamic optimization. The initial interference field generated based on this not only completely covers each geometric element of the instability model, but also realizes the continuous distribution of mechanical parameters at the physical level, forming a virtual support force field that accurately corresponds to the slope instability state. The dynamic field generator then instantiates multiple field generator instances at the spatial positions corresponding to the initial interference field according to the three-dimensional geographic coordinates of the event analysis sub-unit. Each instance establishes a dynamic channel connection with the corresponding event analysis sub-unit through a dedicated data link. In the field model interaction engine built inside the field generator, the optimization algorithm with the multi-objective function of minimizing the support structure weight, maximizing the safety factor, and optimizing the deformation coordination is implanted. The core of the field model interaction engine is a multi-objective optimization system, which aims to simultaneously achieve the minimization of the support structure weight, the maximization of the safety factor, and the optimization of the deformation coordination. The engine receives the local instability feature vector from the event analysis sub-unit in real time through the dynamic channel as the input data of the optimization process. The sequence quadratic programming algorithm based on sensitivity analysis is used for iterative calculation: the algorithm takes the field strength and direction parameters of the initial interference field as the design variables, calculates the sensitivity of the objective function to the variables in each iteration, constructs and solves the quadratic programming sub-problem to determine the parameter update direction, and then checks the safety constraints and adjusts the field distribution with new data.This process is executed in a loop until the optimal interference field parameters that satisfy the multi-objective balance are converged. The channel monitoring unit monitors the transmission load of all dynamic channels in parallel through packet rate detection and buffer depth monitoring. When the load of a specific area channel continuously exceeds the preset threshold, the channel materialization process is triggered, and the high-load channel is converted into an anchor structure with specific mechanical properties. The system finally integrates the corrected interference field parameters and anchor spatial distribution, solves the potential energy field gradient to develop field streamline tracking, and automatically generates the spatial topology of the flexible support net according to the streamline density. The design inclination of the anchor rod is calculated according to the streamline curvature, the support member specification parameters are determined according to the field strength value, and the phased construction timing is deduced in reverse according to the instability risk propagation path, completing the digital conversion from the continuous field model to the discrete support scheme and generating the design scheme of the flexible support.
[0023] In one embodiment, the step of continuously monitoring the real-time load of all dynamic channels, materializing dynamic channels based on a preset super-fusion threshold, and generating anchors for the flexible support net is: The channel monitoring unit continuously monitors the real-time load of all data channels and sets a preset overload threshold. When it is found that the real-time load of one or more dynamic channels within a preset range continuously exceeds the preset overload threshold within a preset time, it is determined that the area is a high-energy core area. The channel monitoring unit sends a freezing application to the dynamic channels in the high-energy core area, and the dynamic channels that receive the freezing application are materialized to generate anchors and record anchor parameters. The anchor data is transmitted to the field model interaction engine. The anchor parameters include spatial positioning parameters, mechanical property parameters, and dynamic correlation parameters. Further, the channel monitoring unit continuously collects transmission state indicators of each dynamic channel through the probe program deployed in the data link layer. These indicators include but are not limited to data packet transmission rate, bit error rate and buffer queue depth. The system preset load threshold is a multi-dimensional dynamic threshold value, the value of which is determined by the channel base bandwidth and the real-time transmitted data type. When the monitoring unit detects that more than half of the dynamic channels in a certain geographical area continuously exceed the upper limit of the threshold value for three sampling periods, the area will be marked as a high-energy core area. At this time, the monitoring unit will send a freezing instruction frame containing a time stamp to the target channel, and the channel receiving the instruction will immediately start the materialization process: first, it stops the normal transmission of data flow, and then converts the channel state parameters at the current time into the mechanical properties of anchor nails. The spatial positioning parameters are determined by analyzing the three-dimensional coordinates of the channel terminal device, and the mechanical performance parameters are converted into tensile strength and anchoring force according to the historical load peak value of the channel. The dynamic correlation parameters are inherited from the original topological connection relationship of the channel. These quantified anchor nail parameter sets are packaged as structured data packets and transmitted in real time to the field model interaction engine through a special interface, providing key spatial anchoring point data for dynamic optimization of flexible support schemes.
