Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of landslide control, and in particular to a real-time landslide monitoring method and system based on multi-sensor fusion and intelligent regulation. Background Art
[0002] Landslide refers to a natural phenomenon in which soil or rock on a slope slides down the slope as a whole or in a dispersed manner along a certain weak surface or weak zone under the action of gravity, due to factors such as river scouring, groundwater activity, rainwater soaking, earthquakes and artificial slope cutting. The moving rock (soil) is called a displaced body or sliding body, and the underlying rock (soil) that has not moved is called a sliding bed. At present, in emergency prevention and control of landslides, multiple piles are usually arranged on the landslide surface to stabilize the landslide, but the multiple piles are usually independent, and there is a lack of measures to connect and reinforce the multiple piles, which affects the effect of landslide prevention and control, making the effect of landslide prevention and control need to be improved.
[0003] Prior art 1, Chinese patent, patent number: 202411585519.0, involves the fields of geological engineering and civil engineering, and in particular, involves a test method for the influence of loess water content changes on slope stability. The content includes: collecting and preparing loess samples, measuring the physical parameters of loess samples, and constructing a multidimensional physical property matrix of loess samples; real-time monitoring of pore water pressure, and calculating the shear stress of loess samples based on the dynamic change data of pore water pressure; based on the shear stress of loess samples and the multidimensional physical property matrix of loess samples, dynamically updating the dynamic stability parameters of the slope, and comprehensively evaluating the instability risk of the slope. Although it solves the problem that traditional slope monitoring technology lacks systematic research on the mechanical properties of loess, resulting in poor accuracy and reliability of prediction results; lacks real-time update of slope stability, resulting in the inability to form an accurate dynamic monitoring and recursive prediction mechanism; cannot issue early warning signals in time, resulting in insufficient emergency response to landslides; however, it does not consider the impact on landslide prevention and control, resulting in the failure of metal reinforcement equipment.
[0004] Prior art 2, Chinese patent, patent number: 202411108782.0 discloses an interface-type landslide highway emergency maintenance and treatment structure and method, the method includes the following steps: Step 1: Calculate the shear reinforcement of the pile foundation according to the thrust; Step 2: Close the highway traffic at the landslide section, mill and excavate the road surface layer and base layer of the highway at the landslide section, and locate the positions of the consolidated pile foundation and the non-consolidated pile foundation; Step 3: Drill holes and pile foundation construction, and tie beam construction between non-consolidated pile foundations; Step 4: Tie the steel skeleton of the raft slab and pour the raft slab concrete to realize the consolidation of the consolidated pile foundation and the raft slab, and the non-consolidated pile foundation and tie beam are supported on the bottom of the raft slab to complete the construction of the first section of the treatment unit; Repeat the above steps to carry out the construction of other treatment units; Step 5: Connect the highway in the non-landslide section with the raft slab at the end of the landslide section through a slab, and carry out landslide control in the landslide section of the slope. Although the highway at the landslide section could be separated from the slope, allowing the operating highway to resume traffic as soon as possible and greatly shortening the construction period, drainage channels were not considered, resulting in unreasonable rainwater drainage management.
[0005] Prior art three, Chinese patent, patent number: 202410304622.7 relates to the field of landslide control technology, and in particular to a landslide control slope drainage and reinforcement system. It includes a slope body, on which an inner slope drainage structure and an outer slope drainage structure are arranged, the inner drainage structure includes a seamless steel pipe and a permeable foam concrete column, the exposed end of the inner drainage structure is connected to the slope intercepting ditch, the surface of the seamless steel pipe is provided with permeable holes and a filter net, the slope intercepting ditch is connected to the slope drainage ditch, and the slope drainage ditch is connected to the slope foot drainage ditch. Although it has the following effects: the setting of the inner drainage structure allows the water inside the slope to enter the permeable foam concrete through the permeable holes, and the water is automatically drained by using the internal and external pressure difference at both ends of the pipe body, the exposed end is connected to the slope surface intercepting ditch, and finally the internal water is discharged from the slope through the external drainage structure, and at the same time the inner drainage structure has a reinforcement effect on the soft soil layer, effectively reducing the probability of landslides in rainy seasons; but detection and early warning are not considered, and timely treatment cannot be carried out when a landslide occurs.
[0006] At present, the existing technologies 1, 2 and 3 lack consideration of the impact on landslide prevention, drainage channels, detection and early warning, resulting in the problem that the landslide prevention effect needs to be further improved. In order to solve the above problems, the present invention provides a landslide emergency prevention technology. Summary of the invention

[0070] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0071] like Figure 1 As shown, this embodiment provides an embodiment of a landslide real-time monitoring method based on multi-sensor fusion and intelligent regulation. In this embodiment, the landslide real-time monitoring method based on multi-sensor fusion and intelligent regulation specifically includes the following steps:
[0072] Step S1: placing at least one sensor inside the metal reinforcement and at key positions of the landslide body to monitor the landslide body data in real time, dividing the monitored landslide body data into multiple grid units; and obtaining the water component imaging data of the slope body in real time under rainfall conditions;
[0073] Among them, the water component data is the moisture content of each grid unit; the sensors include displacement sensors, stress sensors, humidity sensors, and rain monitoring sensors, etc.;
[0074] Step S2: Compare the water component imaging data of the landslide body with the preset water component threshold to obtain the amount of rainwater; automatically adjust the valve opening of the drainage channel and the diversion channel according to the amount of rainwater; calculate according to the amount of rainwater to obtain the stability parameter distribution;
[0075] Step S3: Obtain the safety factor according to the stability parameter distribution, and obtain the instability probability of the slope through the safety factors of multiple grid units; if the instability probability reaches the start threshold, the grouting equipment is automatically controlled to start; when the grouting reaches the grouting threshold, the grouting equipment is turned off; the structural design of the metal reinforcement piles and reinforcement frames is optimized through finite element analysis and adjusted.
[0076] Preferably, in step S1 of the present embodiment, a variety of sensors are placed inside the metal reinforcement and at key positions of the landslide body, including displacement sensors, stress sensors, humidity sensors, and rain monitoring sensors, etc., for real-time monitoring of the landslide body data; the monitored landslide body data is divided into multiple grid units for subsequent analysis and processing; under rainfall conditions, water component imaging data of the slope body is obtained in real time, including the moisture content of each grid unit; through the deployment of multiple sensors, the present embodiment can obtain multi-dimensional data of the landslide body in real time, including displacement, stress, humidity, and rainfall, etc., to provide basic data for subsequent analysis; dividing the landslide body into multiple grid units is helpful to more finely analyze the deformation characteristics and water component distribution of the landslide body, and improve the accuracy and reliability of monitoring; by obtaining water component imaging data, the moisture content distribution inside the landslide body can be intuitively understood, providing an important basis for evaluating the stability of the landslide. In step S2, the water component imaging data of the landslide body is compared with the preset water component threshold to determine the rainfall; the valve opening of the drainage system and the diversion channel is automatically adjusted according to the rainfall to control the moisture content of the landslide body; the stability parameter distribution is calculated according to the rainfall to evaluate the overall stability of the landslide body. This embodiment automatically adjusts the drainage system to timely remove excess water in the landslide body to prevent the risk of landslide caused by water accumulation; the stability parameter distribution is calculated using rainfall and water component data to dynamically evaluate the stability of the landslide body and provide a scientific basis for early warning and prevention; combined with real-time monitoring data and preset thresholds, the system can quickly respond to rainfall events, adjust drainage measures in time, and reduce the possibility of landslides. In step S3, the safety factor is calculated according to the stability parameter distribution to evaluate the instability probability of the landslide body; the instability probability of the slope body is comprehensively evaluated through the safety factors of multiple grid units; when the instability probability reaches the threshold of the start interval, the grouting equipment is automatically started; otherwise, the equipment is shut down; this embodiment optimizes the structural design of metal reinforcement piles and reinforcement frames through finite element analysis to improve overall stability. This embodiment can provide early warning of the possibility of landslides by calculating the safety factor and the probability of instability, thereby providing a time window for emergency response; when the probability of instability reaches a threshold, the system automatically starts the grouting equipment for reinforcement, thereby reducing manual intervention and improving the response speed; this embodiment optimizes the design of the reinforcement structure through finite element analysis, thereby improving the overall stability and durability of the landslide body and reducing the risk of future landslides.
[0077] Furthermore, if Figure 2 As shown, the process of obtaining the water component imaging data of the slope body in real time under rainfall conditions in step S1 specifically includes the following steps:
[0078] Step S11: placing at least one sensor inside the metal reinforcement and at key positions of the landslide body to monitor the landslide body data in real time, dividing the landslide body data into a plurality of grid units; and arranging a plurality of electrodes according to the plurality of grid units;
[0079] Step S12: measuring the resistivity of multiple grids; obtaining the resistivity of any position of the landslide body in real time; performing suction balance on the resistivity to obtain the corresponding resistance value, and obtaining the corresponding water content according to the resistance value;
[0080] Step S13: Obtain the corresponding resistivity according to the resistance value, fit the water content and the resistivity to obtain the corresponding relationship between the resistivity and the water content; discretize the resistivity at different positions in the corresponding grid units to obtain the resistivity corresponding to each grid unit; input the resistivity of each grid unit into the corresponding relationship between the resistivity and the water content to obtain the water content of each grid unit.
[0081] Preferably, in step S11 of this embodiment, at least one sensor is placed inside the metal reinforcement and at key positions of the landslide body to monitor the landslide body data in real time. These sensors may include inclination sensors, displacement sensors, etc., which can monitor parameters such as deformation, displacement and vibration of the landslide body; and through the arrangement of sensor groups, monitoring points are formed, and data such as vibration frequency, inclination offset increment, inclination offset direction and displacement increment of the landslide body are collected in real time; in step S12, the landslide body data is divided to obtain multiple grid units, and each grid unit is used as a basic unit for resistivity measurement; multiple electrodes are arranged according to the grid units, and the resistivity distribution inside the landslide body is measured using a high-density resistivity method; the resistivity of multiple grids is measured to obtain resistivity data at any position of the landslide body in real time; the resistivity is subjected to suction balance processing to obtain the corresponding resistance value, and the water content is calculated based on the resistance value; in step S13, the water content and the resistivity are fitted to obtain the corresponding relationship between the resistivity and the water content; the resistivity at different positions is discretized in the corresponding grid units to obtain the resistivity corresponding to each grid unit; the resistivity of each grid unit is input into the corresponding relationship between the resistivity and the water content to obtain the water content of each grid unit. In this embodiment, the deformation and moisture changes of the landslide body can be monitored in real time and accurately by using a sensor group and a high-density resistivity method, thereby improving the accuracy and real-time performance of landslide early warning. Real-time monitoring of the resistivity changes of the landslide body can quickly respond to changes in the internal structure of the landslide body, thereby providing reliable data support for landslide early warning. Resistivity imaging technology and multivariate data fusion methods can be used to achieve multidimensional imaging and analysis of the internal structure of the landslide body, and accurately determine the location of the potential slip surface and the stability of the landslide body. Combined with data such as soil moisture content and rainfall, a multivariate data fusion model is constructed to improve the accuracy and real-time performance of landslide prediction. The high-density resistivity method can measure the resistivity distribution of the object being measured without disturbing it, thereby improving the spatial resolution of the monitoring data. The design and optimization of the electrode network can meet the needs of large-area risk point inspection and variable-density and variable-range monitoring of key areas.
[0082] Furthermore, if Figure 3 As shown, the process of obtaining the stability parameter distribution in step S2 specifically includes the following steps:
[0083] Step S21: Compare the water component imaging data of the landslide body with the preset water component threshold, and extract features from the landslide body data in combination with the evolution law of the landslide body itself and the landslide deformation mechanism to obtain a rainfall landslide influence feature set;
[0084] Among them, the rainfall landslide impact feature set includes historical displacement data features, rainfall factor features, stability coefficient features, rainfall infiltration depth features, and time factor features;
[0085] Step S22: Generate a predicted displacement sequence for the rainfall landslide impact feature set based on the historical displacement data characteristics, and use the predicted displacement sequence to determine the predicted landslide time; issue an early warning based on the predicted landslide time and upload it to the central control system;
[0086] Step S23: The central control system analyzes the landslide time and automatically adjusts the valve opening of the drainage channel and the diversion channel according to the analysis results; and analyzes the rainfall volume of the predicted results to obtain the stability parameter distribution.
[0087] Preferably, in step S21 of this embodiment, by comparing the water component imaging data of the landslide body with the preset water component threshold, combined with the evolution law of the landslide body itself and the landslide deformation mechanism, the characteristics of the landslide body data are extracted; the rainfall landslide impact feature set is extracted from the landslide body data, including historical displacement data features, rainfall factor features, stability coefficient features, rainfall infiltration depth features and time factor features; step S21 can more accurately identify the potential risk of landslides by combining the evolution law and deformation mechanism of the landslide body itself, and provide a scientific basis for subsequent warnings; and by extracting multiple features, the stability of the landslide can be comprehensively evaluated, thereby improving the comprehensive performance of the early warning system. In step S22, based on the historical displacement data features, a predicted displacement sequence is generated for the rainfall landslide impact feature set, the predicted displacement sequence is used to determine the time when the landslide may occur, and an early warning is issued according to the predicted time; the early warning information is uploaded to the central control system for further processing and response; step S22 can dynamically predict the time when the landslide occurs by predicting the displacement sequence, thereby achieving early warning and reducing disaster losses; uploading the early warning information to the central control system can achieve multi-departmental coordinated response and improve emergency handling efficiency.

[0098] Furthermore, if Figure 6 As shown, the process of obtaining the stability parameter distribution in step S23 specifically includes the following steps:
[0099] Step S231: Analyze and calculate the landslide phenomenon occurring at the corresponding time of the landslide in combination with the historical landslide phenomenon to obtain the valve switch value; automatically adjust the valve opening of the drainage channel and the diversion channel according to the valve switch value;
[0100] Step S232: based on the rainfall landslide influence feature set, the soil-water characteristic relationship is obtained; based on the relationship between soil resistivity and volume water, the relationship between matrix suction and soil resistance is obtained; suction stress is introduced to obtain the relationship between suction stress and water content;
[0101] Step S233: Obtain the stress at any position of the landslide body, use suction stress to replace pore pressure, and obtain the relationship between suction stress and effective stress; analyze the relationship between suction stress and effective stress in combination with rainfall to obtain stability parameter distribution.
[0102] Among them, in step S231, the valve switch value is calculated and the valve opening is adjusted. The historical data is usually presented in the form of time series, such as annual rainfall or monthly displacement. In order to eliminate the dimension difference, the historical data is normalized:
[0103]
[0104] Where, T ref is the reference time, used to convert historical data into dimensionless values; T norm,i represents the normalized value of the i-th historical data; T history,i Represents the i-th historical data (such as rainfall, displacement, etc.).
[0105] Combine the normalized historical data with the current feature parameters and assign different weight coefficients k1 and k2:
[0106]
[0107] In the formula, k1 and k2 are determined through experiments or experience, reflecting the influence of historical data and current data on the valve switching value; B switch Indicates the valve switch value, which is the weighted result of comprehensive historical data and current characteristic parameters; P current Indicates the characteristic parameters of the current landslide phenomenon (such as current rainfall, current displacement, etc.); n indicates the number of historical data;
[0108] The adjustment of the valve opening is based on an exponential function, ensuring a smooth transition of the opening as the switching value changes:
[0109]
[0110] When V switch When V is close to 0, the valve opening θ is also close to 0; switch Much larger than V ref When the valve opening θ approaches the maximum opening θ max ;

[0117] The relationship between suction stress and water content, suction stress σ suction is a function of soil moisture content:
[0118]
[0119] The suction stress decreases with the increase of water content. By fitting the experimental data, the parameters c, d and e are determined, and the power function relationship between the suction stress and water content is established.
[0120] Step S233: Relationship between suction stress and effective stress and distribution of stability parameters. In unsaturated soil, suction stress σ suction Replaces the role of pore water pressure:
[0121] σ′=σ-u a +χ·σ suction
[0122] Where, the total stress σ is determined by the soil deadweight and external load; the pore air pressure u a Usually close to atmospheric pressure; the weight coefficient χ reflects the contribution of suction stress to effective stress, and its value is related to the saturation of the soil; σ′ represents effective stress, which represents the actual stress between particles in the soil;

[0124]
[0125] In the formula, the shear strength τ f Determined by the effective cohesion c′ and the effective internal friction angle φ′:
[0126] τ f =c′+σ′·tan(φ′)
[0127] The shear stress τ is determined by the soil weight and the slope inclination:
[0128] τ=γ·H·sin(α)
[0129] Safety factor F s It is the ratio of shear strength to shear stress, which reflects the stability of the landslide; it quantitatively analyzes the distribution of stability parameters of the landslide and provides a scientific basis for landslide prevention and control; γ represents the gravity of the soil, which represents the weight of the soil per unit volume; H represents the height of the landslide body; α represents the inclination angle of the landslide surface.
[0130] Preferably, in step S231 of this embodiment, the valve switch value is calculated by analyzing the historical landslide phenomenon at the corresponding time of the landslide and combining with the real-time monitoring data; according to the valve switch value, the valve opening of the drainage channel and the diversion channel is automatically adjusted to realize the dynamic management of the drainage in the landslide area; step S231 can more effectively remove the water accumulation in the landslide area and reduce the possibility of landslide by adjusting the valve opening in real time; combined with historical data and real-time monitoring, it can more accurately predict the landslide risk, take measures in advance, and reduce the impact of landslide on the environment and infrastructure. In step S232, based on the influence feature set of rainfall landslide, the soil-water characteristic relationship is established; and through the relationship between soil resistivity and volume water, the suction stress is introduced to obtain the relationship between the suction stress and the water content; the suction stress is used to replace the pore pressure to obtain the relationship between the suction stress and the effective stress; step S232 can more accurately evaluate the possibility of landslide and its stability parameter distribution by establishing the soil-water characteristic relationship and the suction stress model; combined with parameters such as rainfall and soil suction, the landslide risk can be identified earlier, providing a scientific basis for disaster prevention and mitigation.

[0133] Step S32: Compare the instability probability with the preset instability probability threshold. When the instability probability reaches the start threshold, the grouting equipment is automatically controlled to start. When the grouting reaches the grouting threshold, the grouting equipment is turned off, and the instability probability is recalculated. If it is greater than the start threshold, the grouting equipment is automatically controlled to start. Iterate in sequence until it is lower than the start threshold.
[0134] Step S33: extract features from the stability parameter distribution, adjust the rainfall-landslide impact feature data set according to the extracted features, and perform data fusion, so that the adjusted rainfall-landslide impact feature data set at different time points is in a high-dimensional data space, and a dynamic map is established to obtain the quantitative results of the distribution of influencing factors at each position of the metal reinforcement pile and the reinforcement frame.

In step S32, the instability probability is compared with the preset threshold, and when the instability probability reaches the start threshold, the grouting equipment is automatically started; when the grouting reaches the grouting threshold, the grouting equipment is turned off; the instability probability is recalculated, and if it is still greater than the start threshold, the grouting equipment is continued to be started until the instability probability is lower than the threshold; this embodiment reduces manual intervention and improves response speed and efficiency by automatically controlling the grouting equipment; the grouting amount is dynamically adjusted according to the real-time instability probability to ensure the stability of the slope while avoiding waste of resources. In step S33, features are extracted from the stability parameter distribution, and the rainfall landslide impact feature data set is adjusted according to these features; a dynamic map is established in the high-dimensional data space to quantify the distribution of influencing factors at each position of the metal reinforcement piles and reinforcement frames; through the high-dimensional dynamic map, the distribution of influencing factors at different positions can be more intuitively understood, providing a scientific basis for engineering design and construction; reinforcement measures are dynamically adjusted according to real-time data to improve the accuracy and effectiveness of the reinforcement effect.
[0136] Furthermore, if Figure 8 As shown, the process of obtaining the quantitative results of the distribution of the influencing factors of each position of the metal reinforcement pile and the reinforcement frame in step S33 specifically includes the following steps:

This step ensures that all features are on the same scale, which helps to improve the accuracy of subsequent analysis; the standardization method usually includes subtracting the mean and dividing by the standard deviation, so that the mean of the data is 0 and the variance is 1; the covariance matrix is calculated based on the standardized data, and the covariance matrix describes the linear relationship between the data and is a symmetric matrix; the covariance matrix is subjected to eigenvalue decomposition to obtain the eigenvalue and the corresponding eigenvector. The eigenvalue represents the variance of the data in the feature space, and the eigenvector represents the direction of the data in the feature space; based on the size of the eigenvalue, the largest eigenvalue and the corresponding eigenvector are selected to form the principal component. These principal components are used to project the high-dimensional data into a low-dimensional space, thereby achieving dimensionality reduction; the standardized data is projected into a new space composed of the selected principal components to obtain the reduced-dimensional data; the data points at each time point are plotted in the low-dimensional space to construct a dynamic spectrogram. The dynamic spectrum can intuitively display the distribution of data points in the time series; perform quantitative analysis, check the distribution of data points in low-dimensional space and their changing trends, and identify abnormal points. Through principal component analysis, high-dimensional data is projected into low-dimensional space while retaining the main information of the original data as much as possible. This helps to reduce computational complexity and improve the efficiency of data analysis; by selecting the direction of the maximum variance as the principal component, noise and redundant information can be effectively removed, thereby improving the performance and accuracy of the model; the dynamic spectrum can intuitively display the distribution of data points in the time series, helping to identify abnormal points or trend changes; it is of great significance for monitoring and adjusting the structure of metal reinforcement piles and reinforcement frames; quantitative analysis can provide a statistical summary of the impact of each time point or region, providing a basis for subsequent structural adjustments.
