Description

Technical Field

[0001] This invention relates to the field of mechanical performance evaluation technology, specifically to a multimodal wind farm rock high slope support mechanical performance evaluation system. Background Technology

[0002] Against the backdrop of ever-increasing global demand for clean energy, wind power, as an important form of renewable energy, has been widely developed and applied. The scale of wind farm construction is constantly expanding, and their site selection is becoming increasingly diverse, including situations involving sloping areas. During the construction of wind turbine foundations, the stability and support of high rock slopes have become key factors affecting the safe and stable operation of wind farms.

[0003] Currently, in the field of rock slope support for wind farms, existing technologies mainly focus on single analytical methods or local performance assessments. Traditional methods often emphasize theoretical calculations, using simple mechanical models to evaluate slope stability. However, this approach ignores the complexity of rock masses and the diversity of actual working conditions. For example, in calculations, rock masses are typically treated as homogeneous, continuous materials, while actual rock slopes exhibit discontinuous structures such as joints and fissures, which significantly affect the slope's mechanical properties and stability.

[0004] In terms of slope support design, existing technologies mostly adopt experience-based design methods, selecting support types and parameters based on experience from similar past projects. This method lacks in-depth analysis of specific engineering geological conditions and slope characteristics, easily leading to unreasonable support schemes. For example, in some cases, overly conservative support schemes are adopted, increasing project costs; while in other cases, the support strength is insufficient, failing to guarantee the long-term stability of the slope.

[0005] Furthermore, existing technologies lack a systematic and comprehensive approach in assessing the mechanical properties of rock slope supports. They often focus only on one or a few performance indicators, such as anti-sliding and anti-uplift properties, while neglecting other important performance indicators, such as seismic performance. At the same time, there is relatively little research on the compatibility of different support methods with wind turbine tower foundation systems, failing to fully consider the impact of the support structure on the safety and stability of the wind turbine foundation.

[0006] The shortcomings of existing technologies are mainly reflected in the following aspects. First, due to the lack of accurate understanding and consideration of the complex characteristics of rock masses, traditional theoretical calculation methods cannot accurately assess the stability and mechanical properties of high rock slopes, leading to a certain degree of blindness in the design of support schemes. Second, the limitations of empirical design methods make it difficult for support schemes to adapt to different engineering geological conditions and slope characteristics, easily resulting in wasted engineering costs or the existence of safety hazards. Third, single performance evaluation methods cannot comprehensively and systematically understand the mechanical properties of high rock slope support structures, and cannot provide sufficient basis for optimizing support schemes. Finally, insufficient research on the compatibility of support forms with wind turbine tower foundation systems may lead to mutual influence between the support structure and the wind turbine foundation during long-term operation, thereby affecting the normal operation and safety of the wind turbine. Therefore, there is an urgent need for a new technology and system to solve the above problems, and the multimodal wind farm rock high slope support mechanical performance evaluation system of this invention has emerged. Summary of the Invention

[0007] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a multimodal wind farm rock high slope support mechanical performance evaluation system. This system solves the problem of insufficient research on the compatibility between support forms and wind turbine tower foundation systems, which may lead to mutual influence between the support structure and the wind turbine foundation during long-term operation, thereby affecting the normal operation and safety of the wind turbine.

[0008] (II) Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solution: The multimodal wind farm rock high slope support mechanical performance evaluation system of the present invention aims to solve the problems existing in the prior art. Through a combination of indoor model tests and numerical simulation, it conducts a detailed analysis of the construction and support of rock high slopes in wind farm areas and proposes effective slope support schemes.

[0009] System Overall Architecture This system mainly consists of a model testing module, a numerical simulation module, a data analysis and evaluation module, and a scheme optimization module. The model testing module is used to design a scaled-down model of a high rock slope, simulating the support structure of the wind turbine foundation and platform, and monitoring the slope's settlement, displacement, and stress distribution by applying different levels of load. The numerical simulation module performs refined mechanical analysis of the high rock slope and support structure of the wind turbine foundation and platform based on a finite element model. The data analysis and evaluation module processes and analyzes the data obtained from the model tests and numerical simulations, evaluating the mechanical performance of different support methods. The scheme optimization module proposes optimized support schemes based on the results of the data analysis and evaluation.

[0010] Model test module In the model testing module, the first step is to design a scaled-down model of the high rock slope. The design of the scaled-down model must consider the actual geological conditions, slope angle, and soil layer distribution of the high rock slope. Through research and analysis of actual engineering projects, the dimensions and material parameters of the scaled-down model are determined. When simulating the support structure of the high rock slope for wind turbine foundations and platforms, corresponding simulations need to be performed in the scaled-down model based on the actual support methods, such as bolt support, cable support, and retaining wall support.

[0011] To accurately simulate actual working conditions, different levels of load need to be applied to the scaled-down model. Load application can be achieved through a hydraulic loading system or other loading equipment. During loading, the settlement, displacement, and stress distribution of the slope need to be monitored in real time. Settlement and displacement monitoring can be achieved using displacement sensors, while stress distribution monitoring can be achieved using strain gauges or pressure sensors. Analysis of the monitoring data can reveal the impact of different support methods on slope stability.

[0012] Numerical simulation module The numerical simulation module performs refined mechanical analysis of the rock slope and support structure of the wind turbine foundation and platform based on the finite element model. When establishing the finite element model, the nonlinear characteristics of the rock mass and the interaction between the rock mass and the support structure need to be considered. The nonlinear characteristics of the rock mass can be simulated by selecting an appropriate constitutive model, such as the Mohr-Coulomb model or the Drucker-Prager model. The simulation of the support structure can use beam elements, rod elements, or solid elements.

[0013] Finite element modeling can be used to simulate the performance of slope support systems under different rock conditions. Considering the diversity of rock conditions in actual engineering projects, different rock parameters need to be set, such as the elastic modulus, Poisson's ratio, and internal friction angle of the rock mass. During the simulation, stress field, deformation field, and stability analyses are performed. Stress field analysis reveals the stress distribution of the slope and support structure under different working conditions; deformation field analysis reveals the displacement and deformation of the slope; and stability analysis assesses the safety factor and potential failure modes of the slope.

[0014] For slopes with different angles, soil layer distributions, and support methods, their anti-sliding, anti-uplift, and seismic performance are evaluated. For anti-sliding performance evaluation, the slope stability is determined by calculating the slope's anti-sliding safety factor. Uplift performance evaluation is performed by analyzing the tension of anchor bolts or cables. Seismic performance evaluation is performed by simulating the slope's response under seismic loading. These evaluations reveal the mechanical response of slope support structures under complex working conditions.

[0015] Data Analysis and Evaluation Module The data analysis and evaluation module processes and analyzes data obtained from model tests and numerical simulations. First, the monitoring data undergoes preprocessing, including filtering and interpolation, to improve data quality. Then, statistical methods and machine learning algorithms are used to analyze the data. Statistical methods are used to analyze the distribution characteristics and correlations of the data, while machine learning algorithms are used to build predictive models to predict the stability and mechanical properties of slopes.

[0016] When evaluating the mechanical performance of different support methods, multiple performance indicators such as anti-slip, anti-pull-out, and seismic resistance are comprehensively considered. A comprehensive evaluation index system is established to quantitatively assess different support methods. During the evaluation process, the compatibility between the support method and the wind turbine tower foundation system is considered. For example, it is analyzed whether the deformation of the support structure will affect the stability of the wind turbine foundation, and whether the vibration response of the support structure will couple with the vibration of the wind turbine tower.

[0017] Solution optimization module The scheme optimization module proposes optimized support schemes based on the results of data analysis and evaluation. During the optimization process, factors such as overall slope stability, economy, and construction feasibility are considered. Appropriate support methods and parameters are selected for different slope conditions and support requirements. For example, anchor cable support can be chosen when the slope angle is large and the rock mass is fractured; retaining wall support can be chosen when the soil layer is thick.

[0018] The mechanical properties of the support structure are optimized by adjusting parameters such as the length and spacing of anchor bolts and the prestress of anchor cables. Simultaneously, the construction technology and cost of the support structure are considered to select an economical and reasonable support scheme. During the optimization process, the results of numerical simulations and model tests are fully utilized to continuously adjust and improve the support scheme until the optimal effect is achieved.

[0019] The multimodal wind farm rock high slope support mechanical performance evaluation system of the present invention can comprehensively and systematically evaluate the mechanical performance of the wind farm rock high slope support structure, propose optimized support schemes, ensure the safety and stability of wind turbine foundations and platforms in the slope area, and guarantee the safe construction and long-term operation of the wind farm.

[0020] The multimodal wind farm rock high slope support mechanical performance evaluation system of this invention comprehensively and systematically evaluates the mechanical performance of wind farm rock high slope support structures by combining indoor model tests and numerical simulations. In the model tests, by designing scaled-down models and applying different levels of load, actual working conditions can be realistically simulated, accurately acquiring data on slope settlement, displacement, and stress distribution, providing a reliable basis for analyzing the impact of different support forms on slope stability. The numerical simulation module considers the nonlinear characteristics of the rock mass and the interaction between the support structure, performing refined mechanical analysis of the slope support system's performance under different rock conditions, revealing the mechanical response of the slope support structure under complex working conditions. This multimodal evaluation method overcomes the shortcomings of existing single-analysis methods, improving the accuracy and reliability of the evaluation results.

[0021] Economic effects The optimized support scheme proposed by this system can significantly reduce engineering costs while ensuring the overall stability of the slope. The scheme optimization module fully considers the economy and construction feasibility of the support method. By adjusting the parameters of the support structure and selecting a suitable support form, it avoids the problems of overly conservative or insufficiently strong support schemes that may occur in traditional experience-based design methods. For example, in some cases, optimizing the length and spacing of anchor bolts reduces the number of anchor bolts used, lowering material costs and construction difficulty. At the same time, the optimized support scheme can improve construction efficiency, shorten the construction period, and further reduce project costs.

[0022] Social impact The application of this system ensures the safety and stability of wind turbine foundations and platforms in slope areas, guaranteeing the safe construction and long-term operation of wind farms. As an important clean energy project, the safe and stable operation of wind farms is crucial for meeting societal energy demands and reducing environmental pollution. Accurate assessment and optimized design of the mechanical properties of rock slope supports can effectively prevent slope instability and geological disasters, ensuring the normal operation of wind turbine equipment and reducing downtime and maintenance costs caused by slope issues. Furthermore, the research results of this system can provide reference and guidance for similar projects, promoting technological progress and development in the field of wind farm construction.

[0024] Based on the technical problems existing in the background technology, the present invention provides a multimodal wind farm rock high slope support mechanical performance evaluation system, including a model test module, a numerical simulation module, a data analysis and evaluation module, and a scheme optimization module; The model testing module includes a scaled-down model design unit, a load application unit, and a monitoring unit. The scaled-down model design unit is used to design a scaled-down model of the rock slope support structure simulating the wind turbine foundation and platform. The scaled-down model determines its size and material parameters based on the geological conditions, slope angle, and soil layer distribution factors of the actual rock slope.

The numerical simulation module includes a finite element model building unit and a mechanical analysis unit. The finite element model building unit is used to build finite element models of the rocky high slopes and support structures of the wind turbine foundation and platform. This finite element model considers the nonlinear characteristics of the rock mass and the interaction between the support structure. The mechanical analysis unit simulates the working performance of the slope support system under different rock conditions based on the finite element model, performs stress field, deformation field and stability analysis, and evaluates the anti-sliding, anti-uplift and anti-seismic performance of different slope angles, soil layer distributions and support forms. The data analysis and evaluation module is connected to the model test module and the numerical simulation module. It is used to process and analyze the data obtained from the model test and numerical simulation, establish a comprehensive evaluation index system to quantitatively evaluate different support forms, and consider the compatibility of the support forms with the wind turbine tower foundation system. The scheme optimization module is connected to the data analysis and evaluation module. Based on the results of data analysis and evaluation, and considering factors such as overall slope stability, economy and construction feasibility, an optimized support scheme is proposed.

[0025] In the scaled-down model design unit, the scaled-down model is designed based on a detailed geological survey and analysis of the actual wind farm rock slope. By obtaining information on the lithology, joint and fissure distribution, and soil layer thickness of the actual slope, a scaled-down model is made at a certain scale. The support structure in the scaled-down model simulates the actual support forms, such as anchor bolt support, anchor cable support, and retaining wall support, and the materials and layout of the support structure are similar to the actual situation. The size and material parameters of the scaled-down model have been determined through multiple tests and adjustments to ensure that the scaled-down model can accurately reflect the mechanical properties and deformation characteristics of the actual rock slope.

[0026] The load application unit includes a hydraulic loading system or other loading equipment, which can precisely control the magnitude and rate of the load applied to the scaled model. The direction and method of load application are set according to the actual working conditions to simulate different stress conditions, such as vertical loads, horizontal loads, and eccentric loads. During the load application process, the loading equipment and the monitoring unit work together to ensure that the settlement, displacement, and stress distribution data of the scaled model can be accurately obtained under different load levels.

[0027] The monitoring unit includes displacement sensors, strain gauges, and pressure sensors. Displacement sensors are installed at key locations on the scaled-down model to measure slope settlement and displacement. Strain gauges are attached to the support structure and rock surface to measure stress distribution. Pressure sensors are installed between the loading device and the scaled-down model to measure the applied load. The monitoring unit's data acquisition system can record and transmit monitoring data in real time, providing accurate data for subsequent analysis and evaluation.

[0028] In the finite element model, a suitable constitutive model is selected to simulate the nonlinear characteristics of the rock mass, such as the Mohr-Coulomb model or the Drucker-Prager model. The support structure is simulated using beam elements, rod elements, or solid elements, and the interaction between the support structure and the rock mass is realized through contact elements. The mesh generation of the finite element model is optimized according to the complexity of the model and the required computational accuracy to improve computational efficiency and the accuracy of the results.

[0029] When simulating the working performance of slope support systems under different rock conditions, the mechanical analysis unit sets different rock parameters, such as the elastic modulus, Poisson's ratio, and internal friction angle of the rock mass. By simulating different working conditions, such as earthquake and rainstorm conditions, it analyzes the mechanical response of the slope support structure. In the stress field, deformation field, and stability analysis, it adopts a variety of analysis methods, such as static analysis and dynamic analysis, to comprehensively understand the performance of the slope support system.

[0030] The data analysis and evaluation module preprocesses the data obtained from model tests and numerical simulations, including data filtering and interpolation. It uses statistical methods and machine learning algorithms to analyze the data, establish a prediction model, and predict the stability and mechanical properties of the slope. The comprehensive evaluation index system considers multiple performance indicators such as anti-sliding, anti-uplift, and anti-seismic properties, as well as the compatibility of the support form with the wind turbine tower foundation system. Through quantitative evaluation, it obtains a comprehensive score for different support forms.

[0031] When proposing optimized support schemes, the scheme optimization module combines and compares different support forms and parameters to select the optimal scheme. It considers the construction technology and cost of the support structure, and reduces the project cost while meeting the overall stability requirements of the slope. By continuously adjusting the parameters of the support structure, such as the length and spacing of the anchor bolts and the prestress of the anchor cables, it optimizes the mechanical properties of the support scheme, making it more stable and reliable under complex working conditions.

[0032] The system also includes a data storage and management module, which is connected to the model testing module, numerical simulation module, data analysis and evaluation module, and scheme optimization module. This module is used to store and manage various data generated during system operation, including model testing data, numerical simulation data, and analysis and evaluation results. The data storage and management module adopts database technology, which can classify, retrieve, and back up data, making it convenient for users to query and use data, while ensuring data security and integrity.

[0033] Model test module implementation steps First, a detailed geological survey was conducted on a high rock slope of a wind farm to obtain information on the slope's geological conditions, slope angle, and soil layer distribution. Based on the survey results, a scaled-down model was designed at a scale of 1:50. The scaled-down model was made of similar materials to simulate the actual rock mass and support structure. Anchor bolt support structures were incorporated into the scaled-down model, with the arrangement and parameters of the anchor bolts simulated according to the actual engineering design.

[0034] A scaled-down model was mounted on a test bench and connected to a hydraulic loading system and a monitoring unit. The hydraulic loading system was used to apply vertical and horizontal loads to the scaled-down model to simulate different working conditions. The monitoring unit included displacement sensors, strain gauges, and pressure sensors. Displacement sensors were installed at key locations on the slope to monitor settlement and displacement; strain gauges were attached to anchor bolts and the rock surface to monitor stress distribution; and pressure sensors were installed between the loading equipment and the scaled-down model to monitor the magnitude of the applied load.

[0035] During the experiment, the load level was gradually increased, and the load was stabilized for a period of time after each loading. Data was recorded after the monitoring data stabilized. During the loading process, the deformation of the slope was observed in real time, such as whether cracks or slippage occurred. After the experiment, the monitoring data were sorted and analyzed to understand the settlement, displacement, and stress distribution of the slope under different load levels, and to analyze the impact of anchor bolt support on slope stability.

[0036] Numerical simulation module implementation steps Finite element models of the rock slope and support structure for the wind turbine foundation and platform were established using finite element software. In the model, the Mohr-Coulomb constitutive model was selected to simulate the nonlinear characteristics of the rock mass, and the anchor bolts were simulated using bar elements. The rock mass and anchor bolts were connected via contact elements.

[0037] Based on geological survey results, parameters such as the elastic modulus, Poisson's ratio, and internal friction angle of the rock mass are set. Different working conditions, such as earthquakes and rainstorms, are simulated to conduct mechanical analysis of the slope support system. In the earthquake simulation, time history analysis is used, inputting seismic waves to analyze the dynamic response of the slope support structure. In the rainstorm simulation, the influence of groundwater is considered to analyze the slope stability.

[0038] Finite element analysis (FEM) was used to obtain the stress field, deformation field, and stability analysis results of the slope. The safety factor and potential failure modes of the slope under different working conditions were analyzed, and the anti-sliding, anti-pull-out, and seismic performance of the anchor support was evaluated.

[0039] Data Analysis and Evaluation Module Implementation Steps Data obtained from model experiments and numerical simulations are imported into the data analysis and evaluation module. First, the data is preprocessed, including filtering and interpolation, to remove noise and outliers. Then, statistical methods are used for analysis.
