[0002] With the large-scale construction and long-term operation of urban rail transit and underground road networks, a large number of shield tunnels have entered their middle and old age, and the problem of structural performance degradation of shield tunnels is becoming increasingly prominent. In order to ensure the safe and stable operation of shield tunnels and avoid further deterioration of defects that could cause greater economic losses and safety hazards, it is necessary to obtain the optimal repair solution for shield tunnels.

[0003] However, the decision-making process for the optimal repair scheme of existing shield tunnels is cumbersome, which hinders the improvement of decision-making efficiency. This is because current technologies primarily rely on manual decision-making to obtain the optimal repair scheme for shield tunnels. This manual decision-making process requires decision-makers to meticulously review damage information, compare the feasibility of various repair technologies, evaluate repair effects and costs, and conduct a comprehensive assessment based on actual on-site conditions. This cumbersome and time-consuming process increases the time required to obtain the optimal repair scheme for existing shield tunnels, thus hindering the improvement of decision-making efficiency for the optimal repair scheme of shield tunnels. Summary of the Invention

[0072] It should be understood that in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. The terms "comprising," "including," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized.

[0073] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0074] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0075] The repair scheme decision method provided in this application embodiment can be applied to electronic devices, including but not limited to servers, mobile phones, tablets, wearable devices, vehicle devices, and laptops. This application embodiment does not impose any restrictions on the specific type of electronic device.

[0076] Please see Figure 1 , Figure 1 The application scenario diagram of the repair scheme decision method provided in the embodiments of this application is described in detail below:

[0077] The electronic device connects to the monitoring system, sends a data acquisition request to the monitoring system, receives a response message from the monitoring system based on the data acquisition request, parses the response message to obtain the monitoring data of the shield tunnel, and obtains the opening amount of the circumferential joint of the shield tunnel and the misalignment amount of the circumferential joint of the shield tunnel from the monitoring data.

[0078] In this embodiment, the electronic device obtains the opening amount and misalignment amount of the circumferential joint of the shield tunnel from the monitoring data. It can automatically collect the opening amount and misalignment amount of the circumferential joint of the shield tunnel, reduce human error and on-site operation risks, and greatly improve the monitoring efficiency of the circumferential joint of the shield tunnel.

[0079] Please see Figure 2 , Figure 2 This is a flowchart illustrating the repair scheme decision method provided in the embodiments of this application, which can be applied to electronic devices.

[0080] like Figure 2 As shown, the repair solution decision-making method provided in this application embodiment includes the following steps, detailed below:

[0081] S201, Obtain monitoring data of the shield tunnel, and obtain the opening amount of the circumferential joint of the shield tunnel and the misalignment amount of the circumferential joint of the shield tunnel from the monitoring data.

[0082] In shield tunnels, the circumferential joint refers to the joint formed when two adjacent ring segments are spliced ​​along the longitudinal direction of the tunnel. The circumferential joint is a critical connection point in the segment assembly structure of a shield tunnel. Its main functions are to achieve reliable connection between rings, force transmission, and deformation coordination. Simultaneously, it ensures the tunnel's waterproof performance through a waterproof sealing structure, significantly impacting the stability, safety, and durability of the overall tunnel structure.

[0083] S202, Based on the opening amount of the circumferential joint of the shield tunnel, the misalignment amount of the circumferential joint of the shield tunnel, and the preset comprehensive damage model, the comprehensive damage value of the shield tunnel is generated.

[0084] The comprehensive damage model is defined as follows:

[0085] ;

[0086] in, It is the comprehensive damage value of the shield tunnel;

[0088] It is the second weighting coefficient;

[0089] It is the opening amount of the circumferential joint of the shield tunnel;

[0090] It is the misalignment of the circumferential joints of the shield tunnel.

[0091] Combining the opening and misalignment of the circumferential joints of the shield tunnel for fault diagnosis allows for a more comprehensive and accurate identification of anomalies. A single indicator can only reflect localized deformation, while the combined analysis of these two data points can corroborate each other and complement each other, effectively improving the reliability and sensitivity of shield tunnel fault identification. This enables the timely detection of potential safety hazards such as joint leakage, uneven segment stress, structural settlement, and local instability, achieving early warning for shield tunnels.

[0092] S203 When the comprehensive damage value of the shield tunnel is greater than the preset damage value, multiple repair schemes for the shield tunnel are obtained from the design documents of the shield tunnel, and the stiffness recovery index of the shield tunnel under each repair scheme is generated through the preset stiffness recovery model.

[0093] The stiffness recovery model is defined as follows:

[0097] The shield tunnel adopts the first The stiffness of the circumferential joint after repair using the proposed repair scheme;

[0098] It is the reference stiffness of the circumferential joint before the repair of the shield tunnel;

[0099] This represents the proportion of joint stiffness loss due to damage before repair of the shield tunnel, 0 ≤ ≤ 1;

[0100] Indicates the first The stiffness contribution coefficient of the key repair materials in each repair scheme. The higher the value, the better. The greater the contribution of the unit material usage of the key repair material in a repair scheme to stiffness recovery; The smaller the value, the more likely it is that the first... The smaller the contribution of the unit material usage of the key repair material in a repair scheme to stiffness recovery;

[0101] This indicates that the shield tunnel adopts the first Stiffness recovery value of each repair scheme;

[0102] This represents the saturation threshold for stiffness recovery in shield tunnels.

[0103] Among them, the stiffness recovery index is an indicator used to quantitatively evaluate the degree of stiffness recovery of a structure after repair, reinforcement or stress adjustment, reflecting the effect of shield tunnels recovering from a damaged, deformed or weakened state to normal working performance.

[0104] S204. Based on the stiffness recovery index of the shield tunnel under each repair scheme, the stiffness degradation coefficient of the shield tunnel under each repair scheme, the design life of the shield tunnel under each repair scheme, and the preset toughness model, the average toughness index of the shield tunnel under each repair scheme is generated.

[0105] The resilience model is defined as follows:

[0106] ;

[0107] It is the shield tunnel in the The average toughness index of the shield tunnel under each repair scheme was [value missing] on the [number missing]th [year missing]. The higher the average toughness index under each repair scheme, the greater the number of repair schemes. The better the safety of each repair plan; the shield tunnel in the first... The smaller the average toughness index under the first repair scheme, the more it indicates that the second repair scheme is more effective. The worse the security of each repair solution;

[0108] For shield tunnels in the first The design life of the shield tunnel under the repair scheme; the shield tunnel in the... The longer the design life of the repair scheme, the more likely the shield tunnel is to adopt the first repair scheme. The longer the service life of the shield tunnel after each repair and reinforcement plan is completed, the longer the service life of the shield tunnel will be. The shorter the design life under the repair scheme, the more likely the shield tunnel is to adopt the first repair scheme. The shorter the service life of the shield tunnel after each repair and reinforcement plan is completed;

[0109] This indicates that the shield tunnel adopts the first The stiffness recovery index after repair by each repair scheme;

[0110] It is the shield tunnel in the Stiffness degradation coefficient under each repair scheme; The larger the value, the more likely the shield tunnel is to use the first... After the first repair scheme, the faster the performance of the shield tunnel degrades with the passage of time; the smaller the stiffness degradation coefficient, the better the shield tunnel adopts the first repair scheme. After a repair plan is implemented, the rate at which the performance of the shield tunnel deteriorates over time will be slower.

[0111] S205: Obtain the consumption of various repair materials and the energy consumption of various construction machinery in each repair scheme. Based on the consumption of various repair materials and the energy consumption of various construction machinery in each repair scheme, as well as the preset carbon emission model, generate the carbon emission corresponding to each repair scheme. Based on the average toughness index of the shield tunnel under each repair scheme, the carbon emission corresponding to each repair scheme, and the preset comprehensive evaluation model, generate the comprehensive evaluation value of each repair scheme. Select the repair scheme with the largest comprehensive evaluation value as the optimal repair scheme for the shield tunnel.

[0113] For example, there are multiple repair options for shield tunnels, namely the first repair option, the second repair option, and the third repair option;

[0114] When the comprehensive evaluation value of the first repair scheme is the largest, the first repair scheme is selected as the optimal repair scheme for the shield tunnel.

[0115] When the comprehensive evaluation value of the second repair scheme is the largest, the second repair scheme is selected as the optimal repair scheme for the shield tunnel.

[0116] When the comprehensive evaluation value of the third repair scheme is the largest, the third repair scheme is selected as the optimal repair scheme for the shield tunnel.

[0117] The carbon emission model is defined as follows:

[0118] ;

[0125] Indicates the first Energy consumption of the j-th type of construction machinery in each repair scheme;

[0126] Indicates the first The carbon emission factor of the energy used by the j-th type of construction machinery in the repair plan.

[0127] The comprehensive evaluation model is defined as follows:

[0128] ;

[0129] Indicates the first The comprehensive evaluation value of the first repair plan; the first The higher the overall evaluation value of the repair plan, the better. The stronger the overall performance of a repair scheme in terms of both average toughness index and carbon emissions, the better; The smaller the overall evaluation value of the first repair plan, the better. The weaker the overall performance of a repair scheme in terms of both average toughness index and carbon emissions;

[0130] It is the shield tunnel in the Average toughness index under each repair scheme;

[0131] Indicates the first The carbon emissions corresponding to each remediation plan.

[0132] Based on the average toughness index of the shield tunnel under each repair scheme, the carbon emissions corresponding to each repair scheme, and the preset comprehensive evaluation model, a comprehensive evaluation value for each repair scheme is generated. The repair scheme with the highest comprehensive evaluation value is selected as the optimal repair scheme for the shield tunnel. This can effectively reduce carbon dioxide emissions during construction, reduce the impact of the project on the surrounding environment, improve the sustainability and socio-economic benefits of the project, and promote the development of engineering construction towards a green, low-carbon, and high-quality direction.

[0133] For ease of explanation, the following example is provided:

[0134] For example, the repair scheme with the highest comprehensive evaluation value is selected as the optimal repair scheme for the shield tunnel. The optimal repair scheme is the repair scheme of local grouting reinforcement. This can effectively reduce the opening amount and misalignment amount of the circumferential joints of the shield tunnel, significantly improve the structural stiffness recovery index of the shield tunnel, and effectively reduce carbon emissions during construction and reduce the impact of the project on the surrounding environment while ensuring construction quality and structural safety.

[0135] The beneficial effects of the embodiments of this application are as follows:

The repair scheme with the largest comprehensive evaluation value is selected as the optimal repair scheme for the shield tunnel. Since no manual decision-making is required, the decision-making time for the optimal repair scheme of the shield tunnel is reduced, which is conducive to improving the decision-making efficiency of the optimal repair scheme of the shield tunnel.

[0137] Secondly, the higher the comprehensive evaluation value, the stronger the comprehensive performance of the repair scheme in terms of average toughness index and carbon emissions.

[0140] S302. Based on the average toughness index of the shield tunnel under each repair scheme, the carbon emissions corresponding to each repair scheme, and the preset comprehensive evaluation model, a comprehensive evaluation value for each repair scheme is generated. The comprehensive evaluation values ​​of each repair scheme are sorted to generate a ranking result. Based on the ranking result, the repair scheme with the largest comprehensive evaluation value is selected as the optimal repair scheme for the shield tunnel.

[0141] In this embodiment of the application, the repair scheme with the highest comprehensive evaluation value is selected as the optimal repair scheme for the shield tunnel based on the ranking results. This can quickly screen out the optimal repair scheme with the best comprehensive performance and avoid the blindness and uncertainty caused by subjective judgment.
