Description

Technical Field

[0001] This invention relates to the field of construction safety management technology for water conservancy and hydropower projects, specifically a construction safety management system for water conservancy and hydropower projects. Background Technology

[0002] Water conservancy and hydropower engineering construction is a complex and high-risk engineering activity involving multiple construction stages and a large number of construction personnel. In order to ensure safety during the construction process, it is necessary to establish an effective safety management system.

[0003] Currently, existing technologies often lack a systematic and quantitative evaluation system to assess the soundness of management systems. Key factors such as organizational efficiency, the completeness of management systems, and personnel mobility are not fully considered and quantitatively analyzed. Furthermore, traditional safety risk prediction methods often rely on experience and qualitative analysis, making it difficult to accurately predict the changing trends of safety risks. At the same time, the lack of quantitative analysis of key factors in safety inspections and safety training leads to inaccurate safety risk prediction results. Moreover, existing technologies often lack a comprehensive and quantitative indicator to evaluate the effectiveness of safety management, resulting in low safety management effectiveness. Finally, traditional safety management systems often lack a closed-loop, continuous improvement mechanism. The discovery and resolution of safety problems often rely on post-incident handling, making it difficult to achieve real-time control and continuous improvement of safety risks.

[0018] GQ=(SQRT(ZX)×GW) / (1+RL);

[0019] ZX = (GTJ / ZGT) × 100;

[0020] RL = L / ZR;

[0021] in:

[0027] L represents departing employees, and ZR represents the total number of employees.

[0028] Optionally, the formula for calculating the perfection level (GW) of the management system is as follows:

[0029] GW=[(F×ZX×GX) / (ZZ×LZX×LGX)]×100;

[0030] F = FQ / ZQ;

[0031] GX=C / T1;

[0032] F represents the coverage of the system;

[0033] FQ represents the covered area, and ZQ represents the total construction area.

[0034] GX represents the update frequency;

[0035] C represents the actual number of updates, and T1 represents the ideal number of update cycles.

[0036] ZZ represents the total number of system items;

[0037] LZX represents the ideal performance scenario;

[0038] LGX is the ideal update frequency;

[0039] The ideal update cycle number T1, ideal performance LZX, and ideal update frequency LGX are all management parameters that were set during the initial construction and are known.

[0040] Optionally, the calculation formula for the safety risk unit during the construction of water conservancy and hydropower projects is as follows:

[0041] AQ=(GQ×SQRT(A))-[RL×(1-(AP / AP max ))];

[0042] in:

[0043] AQ is the predicted safety risk value;

[0044] A represents the security inspection frequency, with a value range of {0-100}. A indicates the number of security inspections conducted and their effectiveness in the current management cycle.

[0045] AP stands for the number of safety training sessions.

[0046] AP max To maximize the number of safety training sessions, AP max This indicates the ideal number of times an employee should receive safety training.

[0047] Optionally, the formula for calculating the security check frequency A is as follows:

[0048] A=[(AC×AX) / (LAC×LAX)]×100;

[0049] AX = (YH / D) × WL;

[0050] AC represents the number of checks;

[0051] AX represents the inspection result;

[0052] YH represents the number of potential hazards discovered, D represents the total number of inspection points, and WL represents the rectification completion rate.

[0053] LAC represents the ideal number of checks;

[0054] LAX provides the ideal inspection results;

[0055] Ideal inspection count (LAC) and ideal inspection result (LAX) are both management parameters that are set during initial construction and are known.

[0056] Optionally, the calculation formula for the comprehensive evaluation unit of the safety management efficiency of water conservancy and hydropower projects is as follows:

[0057] AN=[AQ×(1-(FL / FL max ))]-[(SQRT(CB) / Y)]×(1-GQ);

[0058] FL = S / T2;

[0059] in:

[0060] AN represents the overall safety management effectiveness value;

[0065] Y represents the total budget.

[0066] Optionally, the management analysis based on the comprehensive security management effectiveness value AN is as follows:

[0067] If the overall safety management effectiveness value AN shows an upward trend on the online graph, it indicates that the effectiveness of current safety management in water conservancy and hydropower construction is improving, and the management system and safety risks are being effectively controlled. The current management of the management system, safety risk management and training strategies should be maintained.

[0068] If the comprehensive safety management effectiveness value AN shows a downward trend on the line graph, it indicates that the effectiveness of the current construction safety management of water conservancy and hydropower projects has decreased, and there are problems such as an unsound management system, increased safety risks, and rising personnel turnover costs. The line graphs of the management system soundness assessment value GQ and the safety risk prediction value AQ should be analyzed.

[0069] The analysis of the trend changes of the management system soundness assessment value (GQ) and the safety risk prediction value (AQ) on the line graph, and the corresponding safety management improvement measures are as follows:

[0070] Management System Soundness Assessment Value (GQ)

[0071] If the management system soundness assessment value GQ shows an upward trend on the online graph, it indicates that the management system is gradually becoming sound, the organizational structure efficiency ZX is improving, the management system perfection GW is increasing, and the staff turnover rate RL is being effectively controlled.

[0072] If the management system soundness assessment value GQ shows a downward trend on the line graph, it indicates that the organizational structure efficiency ZX is decreasing, the management system is imperfect GW and the staff turnover rate RL is increasing within the current management cycle T2, which will have a negative impact on the management system soundness assessment value GQ. Internal communication and decision-making efficiency should be improved, the coverage and implementation of the system should be improved, and the staff turnover rate RL should be reduced.

[0073] Safety risk prediction value AQ

[0074] If the safety risk prediction value AQ shows an upward trend on the graph, it indicates that the safety risk is increasing and has an adverse effect on the safety risk prediction value AQ. The frequency of safety inspections (A) and the number of safety training sessions (AP) should be increased.

[0075] If the predicted safety risk value AQ shows a downward trend on the linear graph, it indicates that the safety risk is decreasing.

[0076] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0077] I. This invention assesses the soundness of the construction safety management system for water conservancy and hydropower projects by evaluating the unit, thereby quantifying the soundness of the management system. It enables quantitative analysis of key elements such as organizational structure efficiency (ZX), management system perfection (GW), and personnel turnover rate (RL). This helps the management system identify weaknesses in the management system and take targeted measures to improve it.

[0078] Second, by predicting safety risk units during the construction of water conservancy and hydropower projects, this invention enables the management system to accurately predict the changing trends of safety risks, thereby reflecting the changes in safety risks more comprehensively. This helps the management system to promptly identify potential safety risks and take corresponding preventive measures.

[0079] Third, this invention, through a comprehensive evaluation unit for the integrated effectiveness of safety management in water conservancy and hydropower engineering construction, enables the management system to assess the overall level of safety management effectiveness. This formula comprehensively considers multiple factors, including the predicted safety risk value AQ, the accident rate FL, personnel turnover cost CB, the total budget Y, and the soundness of the management system. This allows for a more comprehensive reflection of the safety management effectiveness, which helps the management system identify deficiencies in safety management and take effective measures to improve them, thereby enhancing safety management effectiveness.

[0080] Fourth, by observing the rise and fall of the comprehensive safety management effectiveness value AN on the online graph, this invention enables the management system to achieve real-time control and continuous improvement of safety risks. Specifically, when the comprehensive safety management effectiveness value AN decreases, the management system will further observe the rise and fall of the management system integrity assessment value GQ and the safety risk prediction value AQ on the online graph, and conduct separate analysis and safety management modifications. This closed-loop, continuous improvement mechanism helps the management system to continuously optimize the safety management system and improve the level of construction safety.

[0085] 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.

[0086] This water conservancy and hydropower project construction safety management system differs from existing systems. Existing systems often lack a systematic and quantitative evaluation framework to assess the system's soundness, quantitative analysis of key factors in safety inspections and training, a comprehensive and quantitative indicator to evaluate safety management effectiveness, and a closed-loop, continuous improvement mechanism. This algorithm unit, however, achieves comprehensive monitoring and management of construction safety by quantitatively analyzing the system's comprehensive safety management effectiveness value (AN), system soundness evaluation value (GQ), and safety risk prediction value (AQ). Therefore, this management system can accurately predict safety risks, improve safety management effectiveness, and establish a continuous improvement mechanism, effectively addressing the problems and shortcomings of existing technologies.

[0087] Example 1, please refer to Figures 1 to 4 This implementation provides a construction safety management system for water conservancy and hydropower projects, including safety management methods to address issues such as incomplete management systems, frequent personnel turnover, and construction safety risk management.

[0088] It includes a data collection module, a security management assessment and calculation module, a line graph drawing and analysis module, and an implementation and monitoring module;

[0089] The specific management implementation is as follows:

[0090] Data collection module: responsible for collecting data related to management system, personnel flow and construction safety risk management during the construction of water conservancy and hydropower projects within the current management cycle T2;

[0091] Safety Management Assessment and Calculation Module: Responsible for sequentially calculating and outputting the comprehensive safety management effectiveness value AN, the management system soundness assessment value GQ, and the safety risk prediction value AQ;

[0092] Line graph drawing and analysis module: responsible for drawing the comprehensive safety management effectiveness value AN, management system soundness assessment value GQ, and safety risk prediction value AQ into line graphs, observing their changing trends, conducting step-by-step analysis, and formulating targeted safety management improvement measures;

[0093] Implementation and Monitoring Module: Responsible for implementing safety management changes and continuously monitoring changes in the Comprehensive Safety Management Effectiveness Value (AN), Management System Soundness Assessment Value (GQ), and Safety Risk Prediction Value (AQ).

[0094] The safety management assessment and calculation module includes a unit for assessing the soundness of the safety management system for water conservancy and hydropower project construction, a unit for predicting safety risks during the construction of water conservancy and hydropower projects, and a unit for comprehensively assessing the overall effectiveness of safety management for water conservancy and hydropower project construction.

[0095] The equipment used in the data collection module includes sensors, measuring instruments, and data acquisition devices;

[0096] The equipment used in the safety management assessment and calculation module includes computers and software;

[0097] The equipment used in the line graph drawing and analysis module includes visual drawing and analysis tools;

[0098] The equipment used in the implementation and monitoring module includes surveillance cameras and communication equipment.

[0099] In this embodiment, the system utilizes the cooperation of three algorithm units, combining the results of AN, GQ, and AQ calculations to form a complete safety management assessment system. Specifically, GQ is the management system soundness assessment value, which reflects the comprehensive performance of organizational structure, system construction, and personnel stability in safety management. The larger the AN value, the more sound the management system and the higher the capability and level of safety management. AQ is the safety risk prediction value, which helps to identify potential safety hazards in advance and take corresponding preventive measures, thereby reducing the probability of safety accidents. AN is the comprehensive safety management effectiveness value, which helps to fully understand the current safety management status and provides a basis for formulating targeted improvement measures. Furthermore, the calculation results of AN and GQ can also influence the calculation of AQ. Based on the changing trend of AQ, the changing trends of AN and GQ are further comprehensively analyzed, so that the three algorithms of this system work together in their respective algorithms to comprehensively reflect the key elements and their interactions in the construction safety management system of water conservancy and hydropower projects.

[0100] Please see Figures 1 to 4 The calculation formula for assessing the soundness of the construction safety management system of water conservancy and hydropower projects is as follows:

[0101] GQ=(SQRT(ZX)×GW) / (1+RL);

[0102] ZX = (GTJ / ZGT) × 100;

[0103] RL = L / ZR;

[0104] in:

[0105] GQ is the assessment value for the soundness of the management system;

[0106] ZX represents organizational structure efficiency, with a value range of {0-100}. ZX indicates the efficiency of communication, decision-making, and execution within the organization.

[0107] GTJ represents the communication execution decision volume, and ZGT represents the total communication execution decision volume.

[0108] GW represents the completeness of the management system, with a value range of {0-100}. GW indicates the coverage and implementation status of the existing management system.

[0109] RL stands for employee turnover rate;

[0110] L represents departing employees, and ZR represents the total number of employees.

[0111] The formula for calculating the management system perfection level (GW) is as follows:

[0112] GW=[(F×ZX×GX) / (ZZ×LZX×LGX)]×100;

[0113] F = FQ / ZQ;

[0114] GX=C / T1;

[0115] F represents the coverage of the system;

[0116] FQ represents the covered area, and ZQ represents the total construction area.

[0117] GX represents the update frequency;

[0118] C represents the actual number of updates, and T1 represents the ideal number of update cycles.

[0119] ZZ represents the total number of system items;

[0120] LZX represents the ideal performance scenario;

[0121] LGX is the ideal update frequency;

[0122] The ideal update cycle number T1, ideal performance LZX, and ideal update frequency LGX are all management parameters that were set during the initial construction and are known.

[0123] In this embodiment: First, the calculation part of "(SQRT(ZX)×GW)" in this algorithm unit aims to evaluate the direct impact of organizational structure efficiency ZX (internal communication, decision-making, and execution efficiency) on the management system soundness assessment value GQ. It comprehensively reflects the overall effectiveness of the management system by multiplying it with the management system perfection degree GW. SQRT(ZX) represents the square root treatment of organizational structure efficiency ZX, which can smooth the impact of extreme values ​​and make the assessment results more robust. As the numerator of the calculation formula of the unit for assessing the soundness of the construction safety management system of water conservancy and hydropower projects, it directly determines the size of the management system soundness assessment value GQ.

[0124] The “(1+RL)” calculation part is used to adjust the management system soundness assessment value GQ value to reflect the negative impact of personnel turnover rate RL on the soundness of the management system. The higher the personnel turnover rate RL, the worse the stability and continuity of the management system. Therefore, it is necessary to reduce the management system soundness assessment value GQ value through the denominator. As the denominator part of the calculation formula for the unit of assessing the soundness of the construction safety management system of water conservancy and hydropower projects, it plays the role of adjusting the management system soundness assessment value GQ value.

[0125] This algorithm unit uses the management system soundness assessment value (GQ) to calculate key parameters such as organizational structure efficiency (ZX), management system perfection (GW), and employee turnover rate (RL). This clearly reflects the soundness of the management system, which helps to identify weaknesses in the management system in a timely manner and take corresponding improvement measures. Furthermore, the result of the management system soundness assessment value (GQ) can serve as a benchmark for the optimization and improvement of the management system. When the management system soundness assessment value (GQ) is low, in-depth analysis can be conducted on organizational structure efficiency (ZX), management system perfection (GW), and employee turnover rate (RL) to identify the problems and formulate corresponding optimization strategies.

[0126] By assessing the soundness of the management system (GQ), key issues in safety management can be more accurately identified, thereby avoiding blind investment and ineffective management. This helps improve the efficiency of safety management and reduce management costs.

[0127] Please see Figures 1 to 4 The calculation formula for predicting safety risk units during the construction of water conservancy and hydropower projects is as follows:

[0128] AQ=(GQ×SQRT(A))-[RL×(1-(AP / AP max ))];

[0129] in:

[0130] AQ is the predicted safety risk value;

[0131] A represents the security inspection frequency, with a value range of {0-100}. A indicates the number of security inspections conducted and their effectiveness in the current management cycle.

[0132] AP stands for the number of safety training sessions.

[0133] AP max To maximize the number of safety training sessions, AP max This indicates the ideal number of times an employee should receive safety training.

[0134] The formula for calculating the security check frequency A is as follows:

[0135] A=[(AC×AX) / (LAC×LAX)]×100;

[0136] AX = (YH / D) × WL;

[0137] AC represents the number of checks;

[0138] AX represents the inspection result;

[0139] YH represents the number of potential hazards discovered, D represents the total number of inspection points, and WL represents the rectification completion rate.

[0140] LAC represents the ideal number of checks;

[0141] LAX provides the ideal inspection results;

[0142] Ideal inspection count (LAC) and ideal inspection result (LAX) are both management parameters that are set during initial construction and are known.

[0143] In this embodiment, the calculation part of "(GQ×SQRT(A))" first aims to evaluate the positive impact of the management system soundness assessment value GQ on the safety risk prediction value AQ, and comprehensively reflects the role of safety inspection in reducing safety risks by multiplying it by the square root of the safety inspection frequency A. SQRT(A) is also used to smooth extreme values ​​to make the assessment results more robust. As the first part of the calculation formula for the safety risk unit in the construction process of water conservancy and hydropower projects, it directly determines the basic level of the safety risk prediction value.

[0144] “[RL×(1-(AP / AP max The calculation section is used to assess the negative impact of personnel turnover rate (RL) and safety training sessions (AP) on the predicted safety risk value (AQ). The higher the personnel turnover rate (RL), the higher the safety risk, while insufficient safety training sessions (AP) also increase the safety risk. Therefore, this section reflects this negative impact by calculating the product of personnel turnover rate (RL) and the degree of insufficient safety training. As the second part of the calculation formula for the safety risk unit in the construction of water conservancy and hydropower projects, it affects the predicted safety risk value (AQ) from another perspective.

[0145] This algorithm unit, through the safety risk prediction value (AQ), can predict future safety risk trends based on the current safety management status. This helps to identify potential safety hazards in advance and take corresponding preventive measures to avoid safety accidents. Furthermore, the result of the safety risk prediction value (AQ) can provide an important reference for formulating safety management strategies. When the safety risk prediction value (AQ) is high, it is necessary to strengthen safety inspections and safety training to improve employees' safety awareness and operational skills. When the safety risk prediction value (AQ) is low, it is appropriate to reduce the frequency of safety inspections and safety training and allocate resources to other areas where they are more needed.

[0146] The assessment results of the Safety Risk Prediction Value (AQ) can serve as a dynamic feedback mechanism to help continuously optimize safety management strategies. By continuously improving the content, methods, and frequency of safety inspections and training, the accuracy of safety risk prediction can be gradually improved, and the level of safety risk can be reduced.

[0147] Please see Figures 1 to 4 The calculation formula for comprehensively evaluating the overall effectiveness of construction safety management in water conservancy and hydropower projects is as follows:

[0148] AN=[AQ×(1-(FL / FL max ))]-[(SQRT(CB) / Y)]×(1-GQ);

[0149] FL = S / T2;

[0150] in:

[0151] AN represents the overall safety management effectiveness value;

[0152] FL stands for accident incidence rate;

[0153] S represents the number of accidents that occurred, and T2 represents the current management cycle.

[0154] FL max This represents the upper limit for safety incidents.

[0155] CB stands for personnel turnover costs, which represent the recruitment and training costs incurred due to personnel turnover.

[0156] Y represents the total budget.

[0157] In this embodiment, the algorithm unit first "[AQ×(1-(FL / FL) max The calculation section aims to assess the positive impact of the safety risk prediction value AQ on the overall safety management effectiveness value AN, and to evaluate this impact by comparing the accident occurrence rate FL with the safety accident ceiling FL. max The product of the complements of the difference is used to comprehensively reflect the negative impact of the accident rate FL on the comprehensive safety management effectiveness value AN. As the first part of the calculation formula for the comprehensive safety management effectiveness unit of water conservancy and hydropower project construction, it directly determines the basic level of the comprehensive safety management effectiveness value AN.

[0158] The calculation part “[(SQRT(CB) / Y)]×(1-GQ)” is used to assess the negative impact of personnel turnover cost CB on the comprehensive safety management effectiveness value AN. This impact is reflected by multiplying the difference between CB and the management system soundness assessment value GQ. When the personnel turnover cost CB is higher and the management system is not sound, the value of this part will increase, thereby reducing the comprehensive safety management effectiveness value AN. As the second part of the calculation formula for the comprehensive evaluation of the comprehensive effectiveness of construction safety management in water conservancy and hydropower projects, it affects the comprehensive safety management effectiveness value AN from both cost and management system perspectives.

[0159] This algorithm unit can comprehensively reflect an enterprise's overall performance in safety management through the comprehensive safety management effectiveness value AN, including the level of safety risk, accident control capability, cost control capability, and the soundness of the management system. This helps to fully understand one's own safety management status and provides a basis for formulating targeted improvement measures.

[0160] The result of the comprehensive security management efficiency value AN of this algorithm unit can provide an important reference for configuring security management resources. When the comprehensive security management efficiency value AN is low, it is necessary to increase the investment in security management and increase the frequency and quality of security inspections and security training. When the comprehensive security management efficiency value AN is high, it is appropriate to reduce the investment in security management resources and allocate the resources to other places where they are more needed.

[0161] The assessment results of the Comprehensive Safety Management Effectiveness Value (AN) can serve as input for a closed-loop management mechanism, helping to continuously optimize safety management processes and methods. Furthermore, by observing the rise and fall of the AN value on the online graph, problems and deficiencies in safety management can be identified in a timely manner, and corresponding improvement measures can be taken. At the same time, the assessment results of the AN value can also be fed back into the Management System Soundness Assessment Value (GQ) and the Safety Risk Prediction Value (AQ), forming a continuous improvement cycle mechanism.

[0162] Example 2, please refer to Figures 1 to 4 The management analysis based on the comprehensive safety management effectiveness value AN is as follows:

[0163] If the overall safety management effectiveness value AN shows an upward trend on the online graph, it indicates that the effectiveness of current safety management in water conservancy and hydropower construction is improving, and the management system and safety risks are being effectively controlled. The current management of the management system, safety risk management and training strategies should be maintained.

[0164] If the comprehensive safety management effectiveness value AN shows a downward trend on the line graph, it indicates that the effectiveness of the current construction safety management of water conservancy and hydropower projects has decreased, and there are problems such as an unsound management system, increased safety risks, and rising personnel turnover costs. The line graphs of the management system soundness assessment value GQ and the safety risk prediction value AQ should be analyzed.

[0165] The analysis of the trend changes of the management system soundness assessment value (GQ) and the predicted safety risk value (AQ) on the linear graph, and the corresponding safety management improvement measures are as follows:

[0166] Management System Soundness Assessment Value (GQ)

[0167] If the management system soundness assessment value GQ shows an upward trend on the online graph, it indicates that the management system is gradually becoming sound, the organizational structure efficiency ZX is improving, the management system perfection GW is increasing, and the staff turnover rate RL is being effectively controlled.

[0168] If the management system soundness assessment value GQ shows a downward trend on the line graph, it indicates that the organizational structure efficiency ZX is decreasing, the management system is imperfect GW and the staff turnover rate RL is increasing within the current management cycle T2, which will have a negative impact on the management system soundness assessment value GQ. Internal communication and decision-making efficiency should be improved, the coverage and implementation of the system should be improved, and the staff turnover rate RL should be reduced.

[0169] Safety risk prediction value AQ

[0170] If the safety risk prediction value AQ shows an upward trend on the graph, it indicates that the safety risk is increasing and has an adverse effect on the safety risk prediction value AQ. The frequency of safety inspections (A) and the number of safety training sessions (AP) should be increased.

[0171] If the predicted safety risk value AQ shows a downward trend on the linear graph, it indicates that the safety risk is decreasing.

[0172] In this embodiment, a closed-loop management mechanism is formed among the comprehensive safety management effectiveness value AN, the management system soundness assessment value GQ, and the safety risk prediction value AQ. By observing the rise and fall of the comprehensive safety management effectiveness value AN on the linear graph, problems and deficiencies in safety management can be identified in a timely manner, and corresponding improvement measures can be taken. These improvement measures will further improve the values ​​of the management system soundness assessment value GQ and the safety risk prediction value AQ, thereby forming a virtuous cycle of continuous improvement. This will help to continuously improve the level of safety management, reduce the level of safety risks, and ensure the smooth progress of water conservancy and hydropower project construction.

[0173] In this embodiment, the first step is to observe the trend of the overall safety management effectiveness value AN on the line graph. When the overall safety management effectiveness value AN shows an upward trend on the line graph, it indicates that the overall safety management effectiveness is improving. This is due to the effective control of the management system and safety risks. At this time, maintaining the current management system, safety risk management and training strategies can ensure that the momentum of continuous improvement is maintained, thereby achieving long-term safety management stability. When the overall safety management effectiveness value AN shows a downward trend, by analyzing the line graphs of the management system soundness assessment value GQ and the safety risk prediction value AQ, the problem can be quickly identified. For the decline in the management system soundness assessment value GQ, it is necessary to strengthen the construction of the management system. For the increase in the safety risk prediction value AQ, it is necessary to strengthen safety inspections and training. Such targeted improvement measures can quickly improve the overall safety management effectiveness value AN and restore safety management effectiveness.

[0174] Specifically, given the declining trend in the management system soundness assessment value (GQ), it is necessary to optimize the organizational structure and improve internal communication and decision-making efficiency to significantly enhance organizational structure efficiency (ZX), thereby improving the management system soundness assessment value (GQ). This not only helps improve the soundness of the management system but also increases overall work efficiency, reducing safety management problems caused by poor communication and decision-making errors. Improving management systems and increasing their coverage (F) and implementation will directly improve the management system's effectiveness (GW), ensuring the effective implementation of various safety management measures, reducing safety risks, and improving the overall level of safety management. Furthermore, by stabilizing the workforce and reducing turnover, the uncertainty caused by personnel movement can be reduced, helping to maintain the stability and continuity of the safety management team, thus improving the management system soundness assessment value (GQ) and providing strong support for long-term safety management.

[0175] Regarding the downward trend of the safety risk prediction value (AQ), it is necessary to increase the frequency and effectiveness of safety inspections to promptly identify and eliminate safety hazards. This helps to reduce the safety risk prediction value (AQ), reduce safety risks, and ensure the safety of water conservancy and hydropower construction. Increasing the number of safety training sessions (AP) and improving employees' safety awareness and operational skills helps employees better understand and comply with safety regulations, reducing safety accidents caused by improper operation, thereby reducing the safety risk prediction value (AQ).

[0176] In summary, the beneficial effects of the analysis and safety management changes are mainly reflected in improving the overall safety management efficiency, optimizing the management system, reducing safety risks, and achieving economic and social benefits. To realize these effects, it is necessary to continuously monitor the dynamics of safety management, continuously optimize and improve safety management measures, ensure that the construction safety of water conservancy and hydropower projects is effectively controlled, and continuously improve the efficiency of safety management.

[0177] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
