Description

Technical Field

[0001] This invention relates to the field of safety management technology for high-speed tunnel construction, and more specifically, to a method for safety management of high-speed tunnel construction that integrates geological parameters. Background Technology

[0002] In the field of high-speed tunnel construction, safety management is the core element to ensure the smooth progress of the project and avoid casualties and property losses.

[0003] Existing technologies mostly conduct planning during the static planning stage before tunnel construction. However, the static planning stage is generally based on initial geological data and fixed construction plans for risk assessment, without fully considering the dynamic changes of geological parameters during construction. This leads to deviations between the risk assessment results and the actual construction situation. Furthermore, it often focuses on real-time data monitoring of a single construction area and lacks analysis of mutual interference between different construction areas, which can easily result in a failure to provide timely warnings when risks spread. Therefore, a safety management method for high-speed tunnel construction that integrates geological parameters is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a method for safety management of high-speed tunnel construction that integrates geological parameters, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a method for safety management of high-speed tunnel construction that integrates geological parameters is provided, comprising the following steps:

[0006] S1. Obtain geological data and overall construction plan for the high-speed tunnel; S2. Based on geological data and the overall construction plan, the construction area of ​​the high-speed tunnel is divided, and the initial risk range of each area is analyzed. S3. Extract the completed construction areas from the overall construction plan, extract the corresponding construction plans and geological data during the construction period, and combine the geological data of different completed construction areas with the corresponding construction plans to analyze the geological impact and obtain the impact parameters of the plans on the geological parameters of the construction area. S4. Based on historical construction records, conduct interference construction area analysis on the construction plan of the real-time construction area, extract the geological data of the interference construction area and the risk difference between the risk range, then perform similar matching between the real-time construction area and the completed construction area, and extract the construction plan for difference analysis based on the matching results, and use the difference analysis results to combine the influence parameters to predict the influence value analysis. S5. Allocate safety impact values ​​to the real-time construction areas by combining the risk difference of the unfinished construction areas. At the same time, update the remaining part of the predicted impact values ​​of the interfering construction areas according to the plan progress and real-time impact values ​​of the real-time construction areas. Then, compare the predicted impact values ​​with the safety impact values ​​and carry out construction early warning management based on the comparison results.

[0007] As a further improvement to this technical solution, S1 selects geological monitoring equipment based on the geological environment of the high-speed tunnel construction, uses the geological monitoring equipment to conduct geological surveys of the high-speed tunnel, obtains geological data of the high-speed tunnel, and simultaneously establishes a connection with the central control system responsible for construction management to extract the overall construction plan of the high-speed tunnel from the central control system.

[0008] As a further improvement to this technical solution, the steps of S2 are as follows; S2.1. Based on geological data and the overall construction plan, the construction area of ​​the high-speed tunnel is divided into multiple construction areas according to the differences in geological data and construction plans. S2.2 Before construction begins in the construction area, an initial risk range analysis is conducted based on the geological data to obtain the risk range of the construction area.

[0009] As a further improvement to this technical solution, step S3 is as follows: S3.1 Extract the completed construction plans from the overall construction plan, and then determine the completed construction areas corresponding to the completed construction plans; S3.2 Extract the completed construction plans and geological data corresponding to the construction period from the completed construction areas, and then combine the changes in geological data of different completed construction areas with the completed construction plans of the same period to conduct geological impact analysis and obtain the impact parameters of the construction plan on the geological data of the corresponding area during the construction process.

[0010] As a further improvement to this technical solution, in the process of extracting the completed construction area in the overall construction plan, S3 divides the construction area into real-time construction area, incomplete construction area, and completed construction area. The real-time construction area refers to the construction area that is currently under construction. Unfinished construction areas are those where construction has not yet begun. The completed construction area refers to the construction area where construction has been completed.

[0011] As a further improvement to this technical solution, step S4 is as follows: S4.1 Extract historical construction records from the central control system, including construction records of all historical high-speed tunnels; S4.2. Based on historical construction records, conduct interference construction area analysis on the construction plan of the real-time construction area to obtain the interference construction areas that will affect the geological data during the construction process. Then, calculate the difference between the geological data and risk range corresponding to the interference construction area to obtain the risk difference between the interference construction area and the risk range. S4.3. Perform similarity matching between the real-time construction area and the completed construction area to obtain the completed construction area that is most similar to the real-time construction area. Then, perform difference analysis on the construction schemes corresponding to the two construction areas obtained by matching to obtain the construction difference data between the construction schemes. S4.4 Combine construction difference data with influence parameters to conduct a predictive impact numerical analysis on the interference construction area, and obtain the predicted impact numerical value of the geological data of the interference construction area on the real-time construction area completion.

[0012] As a further improvement to this technical solution, in step S4.2, during the process of analyzing the interference construction area of ​​the construction plan in the real-time construction area based on historical construction records, only the completed construction area is selected as the interference construction area, but interference analysis is also performed on the incomplete construction area.

[0013] As a further improvement to this technical solution, step S5 is as follows: S5.1 Extract the unfinished construction areas with construction interference corresponding to the completed construction areas, and combine the real-time construction area and risk difference to allocate the safety impact value, and obtain the safety impact value of the area corresponding to the construction interference. S5.2 Extract the construction plan progress of the real-time construction area and the real-time impact value on the interfering construction area, and then update the predicted impact value of the remaining part based on the construction plan progress and the real-time impact value. S5.3 For areas with interference from construction, compare the predicted impact values ​​updated in S5.2 with the real-time impact values ​​and the safety interference values. If the predicted impact value combined with the real-time impact value is less than the safety disturbance value, monitoring will continue. When the predicted impact value combined with the real-time impact value exceeds the safety disturbance value, construction early warning management will be implemented.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This method for safety management of high-speed tunnel construction by integrating geological parameters extracts geological data and corresponding construction plans from completed construction areas, analyzes the impact parameters of construction plans on geological parameters, and establishes a quantitative relationship between construction behavior and geological changes. Based on this, it combines the similarity matching between real-time construction areas and completed construction areas, as well as the difference analysis of construction plans, to predict the impact values ​​of geological data changes in areas that interfere with construction. At the same time, based on real-time construction progress and real-time impact values, it dynamically updates the remaining predicted impact values ​​and compares them with safety impact values. This method of extracting patterns from historical data and dynamically adjusting prediction results in combination with real-time data breaks through the limitations of traditional static risk assessment, can timely capture the changing trends of risks during construction, and realizes dynamic prediction of construction risks.

[0015] 2. In this method of high-speed tunnel construction safety management that integrates geological parameters, the construction area of ​​the high-speed tunnel is divided by combining geological data and the overall construction plan. Based on the differences in geological conditions and construction arrangements, the tunnel is divided into multiple targeted construction areas. At the same time, the initial risk range of each area before construction is analyzed to clarify the risk type and scope of occurrence. This refined area division and risk assessment based on geological and construction differences allows the management to accurately locate the risk starting point, providing clear goals and directions for subsequent risk control. It avoids the extensive risk assessment of tunnel projects in traditional management and improves the accuracy of risk control. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1 - Figure 5 As shown, the purpose of this embodiment is to provide a method for safety management of high-speed tunnel construction that integrates geological parameters, including the following steps: S1. Obtain geological data and overall construction plan for the high-speed tunnel; Collect basic data (geological data) and core evidence (overall construction plan) for high-speed tunnel construction to provide raw materials for subsequent analysis.

[0019] S1 selects geological monitoring equipment based on the geological environment of the high-speed tunnel construction, uses the geological monitoring equipment to conduct geological surveys of the high-speed tunnel, obtains geological data of the high-speed tunnel, and at the same time establishes a connection with the central control system responsible for construction management (using the database and related interfaces of the system to extract the overall construction plan of the high-speed tunnel), and extracts the overall construction plan of the high-speed tunnel from the central control system.

[0020] A comprehensive assessment of the geological environment for high-speed tunnel construction is conducted, including factors such as the type of surrounding rock, hydrological conditions, and geological structure. Based on this assessment, appropriate geological monitoring equipment is selected, such as convergence meters for monitoring surrounding rock deformation, stress meters for measuring ground stress, and hydrological monitoring instruments for detecting groundwater conditions. Then, based on the selected geological monitoring equipment, geological exploration work is carried out on the high-speed tunnel.

[0021] S2. Based on geological data and the overall construction plan, the construction area of ​​the high-speed tunnel is divided, and the initial risk range of each area is analyzed. The tunnel project is divided into manageable units, and the initial risks before construction of each unit are assessed to identify the starting point of the risks.

[0022] The steps for S2 are as follows; S2.1. Based on geological data and the overall construction plan, the construction area of ​​the expressway tunnel is divided. According to the differences in geological data and construction plans, the expressway tunnel is divided into multiple construction areas. The steps are as follows: Analyze the geological data of the high-speed tunnel to clarify the differences in surrounding rock properties (such as hardness and stability), hydrological conditions (such as groundwater content and water pressure), and geological structures (such as the presence of faults and folds) in different sections. At the same time, study the overall construction plan to understand the differences in construction methods (such as full-face excavation and sectional excavation), construction progress requirements, support methods, and other construction arrangements in different sections. Then, based on the differences in geological data and construction plans, the high-speed tunnel is divided into multiple construction areas (for example, sections with good geological conditions and rapid full-face excavation in the construction plan are divided into one construction area, while sections with complex geological conditions, requiring sectional excavation and high support requirements are divided into another construction area).

[0023] S2.2 Before construction begins in the construction area, an initial risk range analysis is conducted based on the geological data to obtain the risk range of the construction area.

[0024] For each designated construction area, detailed geological data is collected, including the physical and mechanical parameters of the surrounding rock, relevant parameters of groundwater, and specific characteristics of the geological structure. Then, based on the geological data of each construction area and combined with experience in engineering geological risk analysis, the risks that the area may face before construction is carried out are analyzed to determine the types of risks (such as collapse risk, water inrush risk, deformation risk, etc.) and the scope of risk occurrence, thereby obtaining the risk range of the construction area.

[0025] S3. Extract the completed construction areas from the overall construction plan, extract the corresponding construction plans and geological data during the construction period, and combine the geological data of different completed construction areas with the corresponding construction plans to analyze the geological impact and obtain the impact parameters of the plans on the geological parameters of the construction area. By analyzing completed areas, we can clarify the actual impact of construction plans on geological parameters. By quantifying the impact of construction activities on geology, we can provide a basis for predicting the geological risks of subsequent construction.

[0026] The steps for S3 are as follows: S3.1 Extract the completed construction plans from the overall construction plan, and then determine the completed construction areas corresponding to the completed construction plans; The completed construction content is selected from the overall construction plan. The specific construction procedures, technical parameters, and construction time information of each completed construction plan are identified. Then, based on the extracted completed construction plans, the corresponding construction space range is matched to determine the specific construction area covered by each completed construction plan, and the boundaries and scope of the area are clarified.

[0027] S3.2 Extract the completed construction plans and geological data corresponding to the construction period from the completed construction areas. Then, combine the changes in geological data of different completed construction areas with the completed construction plans of the same period to conduct a geological impact analysis and obtain the impact parameters of the construction plan on the geological data of the corresponding area during the construction process. The specific steps are as follows: For each completed construction area, details of the completed construction plan during the construction period are collected. Simultaneously, geological data for that area before, during, and after construction are extracted. Correlation analysis is performed between the changes in geological data of different completed construction areas and the completed construction plans for corresponding time periods to study the effects of various operations within the construction plan on changes in geological data. Finally, through the above analysis, the degree of influence of the construction plan on geological data is quantified, and specific parameters characterizing the impact of the construction plan on the geological parameters of the corresponding area are extracted, such as the rate of change of geological parameters and the influence range coefficient. The formulas are as follows: ; Where T represents the impact of the construction plan on geological parameters, indicating the change in geological parameters per unit of construction intensity; F represents the construction intensity parameter of the completed construction plan, a quantitative indicator that comprehensively considers factors such as construction speed, excavation intensity, and support strength. G represents the change in geological parameters within the completed construction area, calculated by subtracting the geological parameter values ​​before construction from the post-construction geological parameter values.

[0028] In the process of extracting completed construction areas in the overall construction plan, S3 divides the construction areas into real-time construction areas, incomplete construction areas, and completed construction areas. The real-time construction area refers to the construction area that is currently under construction. Unfinished construction areas are those where construction has not yet begun. The completed construction area refers to the construction area where construction has been completed. This will create a clear classification of construction areas, enabling subsequent construction management work to be carried out for different types of areas.

[0029] S4. Based on historical construction records, conduct interference construction area analysis on the construction plan of the real-time construction area, extract the geological data of the interference construction area and the risk difference between the risk range, then perform similar matching between the real-time construction area and the completed construction area, and extract the construction plan for difference analysis based on the matching results, and use the difference analysis results to combine the influence parameters to predict the influence value analysis. Predicting the potential impact of the current construction area on other areas, clarifying the scope and extent of risk spread, providing a forward-looking basis for safety management, dynamically predicting the potential risk spread of the current construction, and achieving early risk prediction.

[0030] The steps for S4 are as follows: S4.1 Extract historical construction records from the central control system, including construction records of all historical high-speed tunnels; retrieve construction records of all historical high-speed tunnels from the central control system, including detailed information such as the division of construction areas for each tunnel, construction plans, changes in geological data, and interference effects. S4.2. Based on historical construction records, conduct interference construction area analysis on the construction plan of the real-time construction area to obtain the interference construction areas that will affect geological data during the construction process. Based on extracted historical construction records, we focus on analyzing cases with construction plans similar to those in the current construction area to identify interfering construction areas that may impact geological data in other areas during the current construction process. In this process, we prioritize completed construction areas as the main analysis objects, while also assessing the possibility of interference in incomplete construction areas, using the following formula: ; Among them, I i，j The value represents the interference influence of construction area i on area j in real time. The larger the value, the more significant the geological influence of construction in area i on area j. n is the total number of geological parameters involved in the evaluation. W k The weight of the k-th geological parameter is set according to the degree of influence of different geological parameters on construction safety, and the sum of the weights is 1. i，k Let G be the k-th geological parameter value of the real-time construction area i. j，k Let S be the value of the k-th geological parameter of region j to be evaluated. i，j This is the spatial distance coefficient between region i and region j. The closer the distance, the larger the coefficient. The value range is 0-1. Simultaneously set an interference threshold, when I i，j If the value exceeds the threshold, it is determined to be an area interfering with construction.

[0031] Then, the geological data corresponding to the interfering construction area and the risk range are compared and the risk difference is calculated to obtain the risk difference between the interfering construction area and the risk range; For the identified areas of interference with construction, collect their current geological data (such as surrounding rock pressure, displacement, and groundwater level) and the risk range of the area (such as the safety threshold and risk warning threshold of geological parameters). Compare the current geological data of the area of ​​interference with the risk range of the area, and calculate the difference between the two to determine the risk difference between the area of ​​interference and the risk range, thereby reflecting the current safety status of the area.

[0032] S4.2 In the process of analyzing the interference construction area of ​​the construction plan in the real-time construction area based on historical construction records, the interference construction area is only selected from the completed construction area, but interference analysis is also performed on the incomplete construction area.

[0033] S4.3. Perform similarity matching between the real-time construction area and the completed construction area to obtain the completed construction area that is most similar to the real-time construction area. Then, perform difference analysis on the construction schemes corresponding to the two construction areas obtained by matching to obtain the construction difference data between the construction schemes. Geological details of the real-time construction area are collected, including the physical and mechanical properties of the surrounding rock, the distribution of geological structures, and the depth of groundwater. Simultaneously, data of the same dimensions from completed construction areas are summarized to establish a standardized comparison database, providing a basis for similarity analysis. Then, a multi-index weighted scoring method is used to comprehensively compare the geological parameters, area scale, and construction environment of the real-time construction area with each completed construction area, calculate the similarity score of each completed area, and select the most similar completed construction area with the highest score.

[0034] For the two matched areas, we conducted an in-depth analysis of their construction plans, making detailed comparisons in terms of the selection of construction technology, the setting of key construction parameters, the configuration of construction equipment, and the construction organization and arrangement. We identified the specific differences between the two and formed a systematic set of construction difference data.

[0035] S4.4. Combine construction difference data with influencing parameters to conduct a predicted impact numerical analysis on the interfering construction area, and obtain the predicted impact numerical values ​​of the completion of construction in the real-time construction area on the geological data of the interfering construction area. The specific steps are as follows: Extract the impact parameters corresponding to the completed construction area, clarify the geological effects of the construction as represented by these parameters, and simultaneously understand the geological status of the interfering construction area and its spatial relationship with the real-time construction area. Combining construction difference data, impact parameters, and relevant information about the interfering construction area, analyze the correlations and mechanisms among various factors to calculate the predicted impact of the real-time construction area on the geological data of the interfering construction area after construction is completed. The formula is as follows: ; in, G e The value representing the predicted impact of real-time construction on the geological data of the interfering construction area is p, where p is the total number of parameters involved in the difference analysis in the construction plan, and w is the number of parameters involved in the difference analysis in the construction plan. m F represents the weight of the m-th construction parameter. rm F represents the value of the m-th construction parameter in the real-time construction area. am To match the value of the m-th construction parameter in the completed construction area, T is the influence parameter of the completed construction area, and L is the straight-line distance between the real-time construction area and the interfering construction area. max β represents the maximum distance value at which geological impacts occur in historical construction records. β is the geological sensitivity coefficient of the area that is disturbed by the construction. It is set according to the geological vulnerability of the area and ranges from 0 to 1.5. The larger the value, the more sensitive the geology and the more obvious the impact.

[0036] S5. Allocate safety impact values ​​to the real-time construction areas by combining the risk difference of the unfinished construction areas. At the same time, update the remaining part of the predicted impact values ​​of the interfering construction areas according to the plan progress and real-time impact values ​​of the real-time construction areas. Then, compare the predicted impact values ​​with the safety impact values ​​and carry out construction early warning management based on the comparison results.

[0037] By combining the risks of unfinished areas, safety impact thresholds are assigned, prediction results are dynamically updated, and early warnings are triggered based on comparison results, thus achieving closed-loop safety management and ensuring construction safety.

[0038] The steps for S5 are as follows: S5.1 Extract the unfinished construction areas with construction interference corresponding to the completed construction areas, and combine the real-time construction area and risk difference to allocate the safety impact value, and obtain the safety impact value of the area corresponding to the construction interference. Based on the construction characteristics of the real-time construction area, risk differences, and the geological sensitivity of the unfinished construction area, a safety impact value is allocated to the areas that may be affected by construction interference. By comprehensively analyzing the possibility and tolerance of interference in each area, the acceptable safety impact value for each area corresponding to the interference is determined, as shown in the following formula: ; Among them, G f，j R represents the safety impact value of the area corresponding to the j-th construction disturbance. c，j Let γ be the risk difference for the j-th interference region. j δ is the geological sensitivity coefficient of the j-th unfinished construction area, which is set according to the geological vulnerability of the area and ranges from 0 to 1. The larger the value, the more sensitive it is. δ is the influence weight coefficient of the real-time construction area, which reflects the degree of influence of real-time construction on the interference area and ranges from 0 to 1. It is determined by the scale and intensity of real-time construction.

[0039] S5.2 Extract the construction plan progress of the real-time construction area and the real-time impact value on the interfering construction area, and then update the predicted impact value of the remaining part based on the construction plan progress and the real-time impact value. Extract the current construction progress of the real-time construction area, such as the completed construction percentage and remaining construction tasks. Simultaneously, collect real-time impact values ​​on the interfering construction areas during the construction process. Based on the real-time construction progress of the construction area and the generated real-time impact values, analyze the potential impact of the remaining construction tasks. By evaluating the correlation between progress and impact, adjust and update the previously predicted remaining impact values ​​to make the prediction results more closely reflect the actual construction progress. The formula is as follows: ; in, G e，new V represents the updated remaining predicted impact value. real V represents the current construction progress in the real-time construction area. total This represents the total amount of construction work in the real-time construction area.

[0040] S5.3 For areas with interference from construction, compare the predicted impact values ​​updated in S5.2 with the real-time impact values ​​and the safety interference values. If the predicted impact value combined with the real-time impact value is less than the safety disturbance value, monitoring will continue, indicating that the current construction risk is within a controllable range. When the predicted impact value combined with the real-time impact value exceeds the safety disturbance value, construction early warning management is initiated, indicating that the construction risk has exceeded the safe range, and construction early warning management measures must be activated immediately to suspend construction.

[0041] From acquiring basic data to regional division and initial risks, to extracting historical patterns and predicting real-time risks, and finally through dynamic early warning management, a full-process safety management system integrating geological parameters, construction plans, and historical experience is formed. The core is to achieve refined, dynamic, and predictable control of construction risks to ensure the safety of high-speed tunnel construction.

Those skilled in the art should understand that the invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
