Description

Technical Field

[0001] This invention belongs to the field of bank protection design technology, specifically relating to a bank protection design method and system based on ecological gabion net technology. Background Technology

[0002] In water conservancy projects and ecological environment management, the stability and safety of slopes and riverbanks are of paramount importance. Gabion mesh, a flexible ecological grid structure woven from high-strength steel wire, is widely used in the protection of river channels, riverbanks and roadbeds due to its good permeability, strong adaptability and integration with the natural environment. Therefore, a reasonable gabion mesh layout scheme is the core to fully exert its protective effectiveness and achieve long-term stability and ecological value.

[0003] However, the current design of gabion netting layout schemes still largely relies on the experience of engineering technicians for manual planning. The design process is characterized by significant subjectivity and uncertainty. The engineers' personal experience, knowledge background, and judgment preferences directly affect the final form of the scheme, resulting in inconsistent design quality and difficulty in achieving optimal parameter matching for specific hydrogeological conditions. Secondly, traditional manual trial-and-error methods are inefficient and costly. To verify the effectiveness of the scheme, repeated on-site adjustments and tests are often required, which greatly prolongs the project cycle. During the long trial-and-error period, the area to be protected may suffer from continuous water erosion, leading to a further expansion of the collapse range and exacerbating safety hazards.

[0004] In view of this, the existing gabion mesh layout design methods based on manual experience are no longer able to meet the precision requirements of modern engineering in terms of accuracy, efficiency and reliability. Therefore, how to establish an efficient and intelligent method for generating and optimizing gabion mesh layout schemes to overcome the inherent defects of traditional manual design has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a bank protection design method and system based on ecological gabion technology, which can select the best gabion layout scheme, so that the bank protection design scheme can take into account the requirements of foundation bearing capacity, structural stability and uniform distribution of gabion nets. In addition, it can also determine the reinforcement area based on historical data, ensuring that the area under the gabion net layout is not easily affected by water erosion and collapse.

[0009] Furthermore, when the layout balance of a certain layout scheme meets the preset optimization conditions, the layout scheme is determined to be the optimal layout scheme.

[0010] Preferably, the step of determining the layout balance of each of the layout schemes includes:

[0011] Obtain all deployment paths included in the deployment plan;

[0012] When the number of deployment paths exceeds the preset path number threshold, the balance value of the deployment scheme is calculated, and the balance value is used as the deployment balance degree of the deployment scheme.

[0013] The preset optimization condition is that the balance value is less than the preset balance value threshold.

[0014] Preferably, the step of calculating the balance value of the deployment scheme includes:

[0020] The matching degree between each deployment path and the flow direction is assessed based on the river's flow direction.

[0021] And based on the matching degree, multiple deployment paths are combined into multiple deployment schemes.

[0022] Preferably, the step of generating multiple deployment paths based on the ground slope information of the revetment area includes:

[0023] Determine the reference lines connecting the start and end points of the revetment area;

[0024] Based on the reference line, multiple deployment paths are generated by setting multiple offset schemes consisting of offset angles and offset distances.

[0025] Preferably, before determining the layout balance of each of the layout schemes, the method further includes:

[0026] Calculate the number of gabion nets required for each layout scheme, and determine the number of gabion nets to be the layout strength of the layout scheme.

[0027] When the strength of the installation exceeds the preset foundation bearing capacity threshold, an insufficient bearing capacity warning signal is output.

[0028] The initial data also includes the foundation bearing capacity of the area corresponding to the layout plan.

[0029] Preferably, after determining the optimal deployment scheme, the method further includes:

[0030] Based on the optimal layout plan, calculate the mass of stones per unit layout area as the unit mass;

[0031] Calculate the unit force per unit area based on fluid velocity field data;

[0032] The offset reference value is determined based on the difference between unit mass and unit force, and the layout path that constitutes the optimal layout scheme is adjusted based on the offset reference value to obtain the adjusted layout path; the initial data also includes stone mass and fluid velocity field data.

[0033] Preferably, the method further includes determining deployment schemes other than the optimal deployment scheme as secondary deployment schemes;

[0034] After determining the secondary deployment plan, the method also includes:

[0035] The deployment paths included in the secondary deployment scheme are marked as dangerous deployment paths, and the deployment areas covered by dangerous deployment paths are marked as dangerous deployment areas.

[0036] In addition, within the hazardous deployment area, the number of gabion nets is increased based on the offset direction of the hazardous deployment path to generate a reinforcement deployment scheme.

[0040] Multiple deployment schemes are generated based on the initial data, and the deployment balance of each scheme is determined.

[0041] Furthermore, when the layout balance of a certain layout scheme meets the preset optimization conditions, the layout scheme is determined to be the optimal layout scheme.

[0042] The scheme verification module is configured to perform preset quality verification and unit force verification on the optimal layout scheme determined by the scheme selection module, and adjust the layout path that constitutes the optimal layout scheme based on the verification results.

[0043] Preferably, the scheme selection module is configured as follows:

[0044] Based on the ground slope information of the revetment area, multiple deployment paths are generated;

[0045] Based on the river's flow direction, assess the matching degree between each deployment path and the flow direction;

[0047] And calculate the balance value for each deployment scheme, so as to use the balance value as the deployment balance degree of the deployment scheme.

[0048] Beneficial effects

[0049] This invention generates multiple deployment paths by setting multiple offset schemes, and combines the deployment paths into multiple deployment schemes based on the matching degree between the deployment paths and the river flow direction. The deployment balance degree of each deployment scheme is determined based on its balance value, and the optimal deployment scheme is determined by combining preset optimization conditions. Therefore, this invention introduces a quantitative evaluation of matching degree and deployment balance degree, transforming the revetment design into a data-driven process, ensuring that the gabion mesh deployment adapts to river information and achieves a reasonable distribution of deployment intensity, avoiding stress concentration, thereby improving the overall stability of the revetment structure.

[0050] After determining the optimal layout scheme, this invention further verifies the mass and unit force of stones per unit layout area, and adjusts the layout path based on the difference between the two. This allows for an accurate assessment of the layout scheme's ability to resist water erosion, and through dynamic optimization, improves the accuracy and feasibility of bank protection design.

[0051] For secondary deployment schemes, this invention identifies the covered area as a dangerous deployment area and increases the number of gabion nets deployed in this area to perform reinforcement, forming a reinforcement deployment scheme. The reinforcement deployment scheme is then re-evaluated for deployment balance to complete safety correction. Thus, this invention transforms secondary deployment schemes into risk warning signals. Through the accurate identification and targeted reinforcement of potential weak points, it achieves comprehensive safety assurance capabilities for the revetment area. Attached Figure Description

[0052] Figure 1 This is a flowchart of an embodiment of the present invention. Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the scope of protection of the invention.

[0054] Example 1

[0055] Please see Figure 1 As shown, this embodiment discloses a bank protection design method based on ecological gabion net technology. Through steps such as information collection and processing before gabion net deployment, planning and analysis of the deployment scheme, and result evaluation and optimization, a practical bank protection design process is formed. The specific process includes the following steps:

[0056] Acquire initial data containing information on the bank slope structure and river of the revetment area; generate multiple layout schemes based on the initial data and determine the layout balance of each scheme; and determine the optimal layout scheme when the layout balance of a certain scheme meets the preset optimization conditions.

[0057] Specifically, initial data on the revetment area is obtained. This information forms the basis for all subsequent design and evaluation steps. The initial data includes the following aspects:

[0058] Bank slope structure of the revetment area: used to assess the construction foundation and stability of the revetment project. Specifically, the geological structure of the bank slope is obtained through geological exploration, and parameters such as soil and rock type, layer thickness, density and shear strength are identified. At the same time, high-precision ground slope information is obtained through UAV aerial survey or lidar scanning, including but not limited to the slope angle, slope height, slope curvature of each section, and whether there are local depressions or protrusions.

[0059] River information: used to assess the dynamic effects of water flow on bank protection structures. Specifically, river flow velocity is obtained through hydrological station data or field measurements, especially the peak flow velocity during historical flood periods; riverbed structure is obtained through sonar detection or physical mapping to understand the scouring and deposition patterns of the riverbed; and long-term river water level data is collected.

[0060] In this embodiment, to more accurately assess the risks under different hydrological conditions, a step of determining water potential time periods is also included. This involves classifying historical time periods based on the comparison between river water levels and preset standard water levels to distinguish working conditions with different water flow risks. Specifically, based on the river water level data obtained from multiple historical time periods, a preset standard water level is set. This preset standard water level can be determined according to local flood control standards, ecological water demand requirements, or historical average water levels. Each historical time period is iterated to determine whether the river water level recorded in that historical time period is higher than the preset standard water level. If so, the historical time period is marked as a high water potential time period. These periods represent times with strong water flow scouring force and high bank protection risk, and are working conditions that need to be focused on in the design. If not, the historical time period is marked as a low water potential time period, and its data can be used to evaluate the bank protection performance under normal conditions.

[0061] Furthermore, after acquiring the initial data, the specific layout path of the gabion mesh is planned. This path is a single spatial curve planned on the digital elevation model to guide the specific placement and orientation of the gabion mesh. Based on the ground slope information of the revetment area obtained in the above steps, the designer or an algorithm automatically sets the start and end points of the revetment area on the digital elevation model; a reference line connecting the start and end points is determined, which is usually a smooth curve generated along the current or planned shoreline.

[0062] Based on a reference line, multiple offset schemes are generated by setting offset angles and offset distances. An offset scheme is a parameter combination consisting of an offset angle and an offset distance, used to generate a unique deployment path from the reference line, thus generating multiple deployment paths. The offset distance determines the lateral distance between the deployment path and the reference line, i.e., the width of the gabion revetment; while the offset angle determines the local orientation of the deployment path, representing the angle parameter by which the local orientation of the deployment path deviates relative to the reference angle. Each deployment path corresponds to a specific offset scheme.

[0063] Specifically, the method for determining the offset angle includes: automatically obtaining the tangent direction of each point along the reference line and calculating the slope angle at that point; based on the slope angle, further calculating the angle parallel to the water contact line; and using the calculated angle as the reference angle. The purpose is to ensure that the foundation layout direction of the gabion net can fit well with the natural shape of the bank slope, thereby obtaining initial stability.

[0064] The specific steps for generating multiple deployment paths include: based on the reference angle calculated above, setting positive offset angles and negative offset angles. For example, with the reference angle as 0 degrees, setting multiple offsets such as ±5 degrees and ±10 degrees, and using the positive offset angle and negative offset angle as offset angles respectively, combined with different offset distances, a series of deployment paths with different spatial forms can be generated. The purpose of setting the positive and negative offset angles is to simulate different interaction modes between the gabion structure and the water flow. Positive offset is usually beneficial for guiding the water flow, while negative offset may have a better energy dissipation and blocking effect.

[0065] To further explain, the forward offset angle is set based on the reference angle, making the deployment path tend to follow the direction of the water flow; the reverse offset angle is set based on the reference angle, making the deployment path tend to resist the direction of the water flow, and is usually used to enhance the energy dissipation effect.

[0066] The generated multiple deployment paths need to undergo preliminary screening to assess their compatibility with hydrological conditions. This step is based on the river's flow direction, evaluating the matching degree between each deployment path and the flow direction. Specifically, the river's flow direction is processed into a vector field, and each deployment path is also processed into a set of vector segments. By calculating parameters such as the angle between the path vector and the flow direction vector, and the projection, a quantitative matching degree is obtained. A high matching degree usually means that the path orientation is more consistent with the water flow direction, the normal component of the water flow impact is smaller, and the structure is more favorable for stress.

[0067] Based on the matching degree calculated in the previous step, multiple deployment paths are combined to form multiple deployment schemes. Each deployment scheme contains at least one deployment path, typically a group of spatially adjacent and functionally complementary deployment paths. For example, a deployment scheme may consist of a main path with a high matching degree and several auxiliary paths for edge protection. The purpose of this step is to elevate the assessment of a single path to a comprehensive planning of the entire revetment structure system.

[0068] For each generated layout scheme, it is necessary to calculate its engineering volume and impact on the foundation, and calculate the number of gabion nets required for each layout scheme. This is usually done by calculating the total area or volume covered by the scheme, and then converting it according to the specifications and filling rate of the gabion nets. The calculated number of gabion nets is defined as the layout strength of the layout scheme. Layout strength is an important indicator for measuring the economic efficiency of the scheme.

[0069] After determining the deployment intensity, the foundation bearing capacity must be checked. Specifically, the foundation bearing capacity of the area corresponding to the deployment scheme is obtained, and this data comes from the geological structure information obtained in the above steps. The calculated deployment intensity is converted into the pressure generated by the total weight and compared with the foundation bearing capacity to verify the foundation stability. The system internally sets a preset foundation bearing capacity threshold, which is usually the foundation bearing capacity multiplied by a safety factor, such as 0.8. That is, the preset foundation bearing capacity threshold is a safety judgment benchmark used for foundation bearing capacity check, usually obtained by multiplying the foundation bearing capacity by a safety factor less than 1. It is determined whether the pressure generated by the deployment intensity exceeds the preset foundation bearing capacity threshold. If so, it means that the scheme may lead to foundation instability or excessive settlement, and an insufficient bearing capacity warning signal will be output to remind the designer to readjust the scheme, such as reducing the deployment range, using lightweight filling materials, or reinforcing the foundation.

[0070] An excellent revetment design not only requires sufficient strength, but also a uniform mechanical distribution within its internal structure to avoid stress concentration. Therefore, it is necessary to assess the balance of each layout scheme. Specifically, this involves obtaining all the layout paths included in the scheme and determining whether the number of paths exceeds a preset threshold, such as three. This threshold is set because the concept of balance is not very meaningful when the number of paths is too small.

[0071] If so, the balance value of the layout scheme is calculated. The calculation process includes: calculating the balance parameters of each layout path in the layout scheme. The balance parameters are comprehensive indicators used to quantify the structural importance or load-bearing contribution of a single path in the whole scheme. The calculation can comprehensively consider factors such as path length, curvature, and the number of gabion nets required. Based on the balance parameters of all paths, the skewed paths in the layout path can be identified, that is, the paths whose balance parameters are significantly higher than the average value. These paths are the main load-bearing parts or structural weaknesses in the scheme.

[0072] Furthermore, the offset directions of all biased paths in the deployment scheme are obtained. These directions, typically determined by their offset angles, are the primary features of the biased paths and are crucial inputs for calculating the balance value. Based on the offset directions of all biased paths, the balance value is calculated through vector synthesis or statistical distribution analysis. This value is used to quantitatively evaluate the uniformity of the structural mechanical distribution within the deployment scheme. For example, if the offset directions of all biased paths are concentrated within a very small angular range, it indicates that the scheme's protective capability has a clear directionality and may be vulnerable to attacks from other directions. In this case, the calculated balance value will be higher. Conversely, if the offset directions are evenly distributed, the balance value will be lower.

[0073] Furthermore, determining whether the balance value is less than the preset balance value threshold is a preset value used to determine whether the balance of the layout scheme is qualified. If it is, it indicates that the internal structure distribution of the scheme is reasonable and the stress is uniform. The layout scheme is determined to be the best layout scheme, and the layout strength of the best layout scheme is determined to be the optimal layout strength. For schemes that do not meet the balance value requirements, they are determined to be secondary layout schemes, which are considered to have structural imbalance risk and are left for subsequent risk analysis and reinforcement design.

[0074] In this embodiment of the application, after determining the optimal deployment scheme, to ensure its high reliability at both the macro and micro scales, the following optimization and verification steps are also included:

[0075] Centroid Comparison: This step aims to assess the macroscopic impact of the revetment structure on the river morphology, calculate the geometric centroid of the optimal layout scheme in the plane, and simultaneously pre-determine geometric reference points on both banks of the river, such as specific points on the river centerline or stable landmarks on the opposite bank. By comparing the positional relationship between the geometric centroid of the scheme and these reference points, centroid comparison parameters are obtained. These parameters can reflect whether the construction of the revetment project will lead to the overall displacement or narrowing of the river channel, thereby assessing its long-term impact on the river morphology.

[0076] Mass verification: This step involves a microscopic assessment of the amount of structural materials used. Based on the optimal layout plan, the mass of stones per unit area within the layout zone is calculated. This requires a comprehensive calculation considering the volume of the gabion mesh, the density of the filling stones, and the porosity. The calculated mass of the stones is then defined as the unit mass, which serves as an indicator for assessing the structural resistance. The unit area refers to the standard unit of area used in both mass verification and unit force verification, such as one square meter.

[0077] Unit force verification: This step assesses the structure's resistance to water erosion by acquiring fluid velocity field data during periods of high water potential. This data can be obtained through hydrodynamic model simulation or historical measured data. Based on this data, the unit force (i.e., water flow impact pressure) per unit area is calculated under the most unfavorable conditions. The unit mass obtained in the previous steps, representing the structure's resistance, is compared with this unit force to evaluate the revetment structure's ability to resist water flow impact at a microscale. The unit force is the water flow impact pressure acting on a unit area during periods of high water potential.

[0078] Layout path update: If the comparison results show that the unit mass is insufficient to resist the unit force, i.e. there is a safety risk, the plan needs to be adjusted. Based on the difference between the unit mass and the unit force, the offset reference amount is determined. This reference amount can be directly related to the increase in gabion mesh thickness or stone density. Based on this offset reference amount, the offset angle or offset distance of the layout path that constitutes the optimal layout plan is automatically adjusted. For example, the offset distance is increased to thicken the revetment structure, thereby obtaining an adjusted layout path that can meet the safety requirements.

[0079] In this embodiment of the application, those schemes identified as secondary deployment schemes in the above steps are not directly discarded, but are identified and processed as potential risk areas, specifically including the following steps:

[0080] Identify hazardous areas: Extract the deployment paths included in the secondary deployment scheme and mark them as hazardous deployment paths. These paths are identified as secondary because they have poor balance and structural weaknesses. Then, the deployment areas covered by these hazardous deployment paths are marked as hazardous deployment areas, which are revetment areas covered by one or more hazardous deployment paths that require reinforcement.

[0081] Implement reinforcement layout: In the identified hazardous layout areas, carry out targeted reinforcement design. Specifically, based on the offset direction of the hazardous layout path, increase the number of gabion nets in that direction, such as increasing the number of layers or reducing the mesh spacing, to generate a reinforcement layout scheme. The purpose of this is to use additional engineering work to make up for the lack of structural balance in the original scheme.

[0082] Safety correction: Reinforcement measures may change the stress characteristics of the original scheme or even introduce new imbalances. Therefore, the above steps of determining the balance of the reinforcement layout must be repeated for the reinforcement layout scheme. By recalculating its balance value and comparing it with the preset balance value threshold, its safety can be corrected to ensure that the reinforced scheme is stable and reliable.

[0083] Through the above series of processes, this application enables the rapid deployment, scientific evaluation, and precise optimization of ecological gabion nets in dynamic watershed environments, greatly improving the scientific, economic, and ecological compatibility of riverbank protection structures.

[0084] Example 2

[0085] This embodiment discloses a bank protection design system based on ecological gabion technology. This system executes the bank protection design method based on ecological gabion technology described above. It can comprehensively consider multiple factors such as bank slope structure, river dynamics, and foundation bearing capacity, automatically generate, evaluate, and optimize the layout scheme of the ecological gabion, and ultimately output a scientific, stable, and economical optimal layout scheme. The system specifically includes:

[0086] The information acquisition module is used to acquire initial data containing information on the bank slope structure and river within the revetment area. In a specific execution flow, by connecting to external data sources or receiving user input, it acquires the basic information required for revetment design. Bank slope structure data may include high-precision digital elevation models (DEMs) or 3D point cloud data obtained through UAV oblique photography, LiDAR scanning, or traditional surveying methods, from which ground slope information of the revetment area can be extracted. River information may include historical hydrological data, river cross-section maps, and river flow direction and fluid velocity field data obtained through fluid dynamics model simulation or field measurements. Other initial data related to engineering safety also needs to be acquired, such as foundation bearing capacity data obtained from geological exploration reports, and the quality information of the stones filling the gabion mesh as determined by design specifications. All acquired initial data is integrated and formatted for use by subsequent modules.

[0087] The scheme optimization module, used in response to the initial data acquired by the information acquisition module, is configured to generate and optimize the execution scheme. Its workflow specifically includes: determining the starting and ending points of the design within the revetment area based on the acquired ground slope information, and connecting the two points to generate a reference line; generating multiple geometrically diverse layout paths based on the reference line by setting multiple offset schemes composed of different offset angles and distances; evaluating the geometric relationship between each layout path and the main flow direction based on the acquired river flow direction information, calculating a matching degree, which measures the compliance or guiding effect of the layout path on the water flow; and combining multiple layout paths with similar or complementary matching characteristics based on this matching degree to form multiple preliminary layout schemes.

[0088] Before optimizing the layout scheme, a pre-verification is performed. This involves calculating the required number of gabion meshes for each scheme and defining this number as the layout strength. Simultaneously, this strength is compared to a preset foundation bearing capacity threshold obtained from initial data. If the strength of a scheme exceeds this threshold, an insufficient bearing capacity warning signal is output, and the scheme may be excluded from subsequent optimization or marked as requiring foundation reinforcement. For layout schemes that pass the pre-verification, their layout balance is determined. When the number of layout paths in a scheme exceeds a preset path number threshold, a balance calculation program is initiated. This program calculates a balance parameter for each layout path in the scheme, which comprehensively reflects factors such as path length, curvature, and expected stress. Based on these balance parameters, paths whose parameter values ​​deviate from the average level are identified as biased paths. Based on the distribution of the offset directions of all biased paths (e.g., the degree of dispersion or central tendency of the directions), a comprehensive balance value is calculated and used as the layout balance degree of the deployment scheme. The layout balance degree of each deployment scheme is compared with a preset optimization condition. In this embodiment, the preset optimization condition is that the balance value is less than a preset balance value threshold. When the balance value of a deployment scheme meets this condition, the deployment scheme is determined to be the optimal deployment scheme. Simultaneously, all other deployment schemes not selected as optimal are determined as secondary deployment schemes.

[0089] The scheme verification module is responsible for the final fine-tuning and risk assessment of the schemes output by the scheme optimization module. In response to the optimal and secondary layout schemes determined by the scheme optimization module, it is configured to perform the following operations: On the one hand, it performs quality verification and unit force verification on the optimal layout scheme. Based on the optimal layout scheme and the stone mass in the initial data, it calculates the stone mass per unit layout area, i.e., the unit mass. At the same time, using the fluid velocity field data, it calculates the unit force on the unit layout area under the design flood conditions. By comparing the difference between the unit mass (resistance) and the unit force (action force), it determines an offset reference. Based on this offset reference, it fine-tunes each layout path that constitutes the optimal layout scheme, such as adjusting its local position or curvature, to obtain an adjusted layout path that is more resistant to water erosion, thus forming the final design scheme that can be constructed. On the other hand, risk analysis and reinforcement processing are carried out on the secondary layout scheme. The layout paths included in the secondary layout scheme are marked as dangerous layout paths, and the layout areas covered by these paths are marked as dangerous layout areas. These areas may represent layouts that are at risk of instability under certain unfavorable working conditions. Within these dangerous layout areas, the number or layers of gabion mesh can be intelligently increased based on information such as the offset direction of the dangerous layout paths, thereby generating a reinforcement layout scheme. This reinforcement scheme can serve as an emergency plan or construction guidance for key protection areas.

[0090] This application, through the collaborative work of the aforementioned information acquisition module, scheme optimization module, and scheme verification module, can achieve intelligent and refined management of the entire process of ecological gabion net revetment design. It can not only automatically find the best layout scheme, but also perform dynamic verification and fine-tuning of the scheme, and identify dangerous layout areas and provide reinforcement suggestions, thereby improving the safety and efficiency of revetment engineering design. It is suitable for river revetment engineering design projects with complex hydrological conditions and diverse bank slope morphologies.

[0091] The above description is merely a preferred embodiment of this application and is not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
