Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of big data analysis, and particularly relates to a method for dynamically optimizing the spacing of pull bolts of hydraulic structures based on big data analysis. BACKGROUND

[0002] Hydraulic structures play a crucial role in many fields such as water conservancy projects, port projects, bridge projects, etc. Structures such as water locks, dams, water conveyance pipelines, and bridge piers, etc. not only bear their own gravity loads, but also are subjected to dynamic loads such as concrete pouring impact, pulsating pressure, and vortex-induced vibration in a complex concrete pouring environment for a long time. These dynamic loads have a significant impact on the structural safety of hydraulic structures, especially the reliability of their connecting components, such as pull bolts. Pull bolts are commonly used connecting components in hydraulic structures, which play a key role in ensuring the integrity and stability of the structure. By reasonably arranging the pull bolts, the internal forces of the structure can be effectively transmitted, external loads can be resisted, and the safe operation of the hydraulic structure under various working conditions can be ensured. For example, in the gate structure of a water lock, pull bolts are used to connect various components to form a whole, which can withstand the pressure of concrete pouring.

[0003] Existing design methods often focus on the calculation of static loads, but do not adequately consider the impact of dynamic loads such as concrete pouring impact. The dynamic action of concrete pouring can cause additional stress and deformation on the pull bolts, which may lead to bolt loosening, fatigue damage, or even rupture under long-term action. However, fixed bolt spacing design cannot adapt to such dynamically changing load conditions, which may result in insufficient bolt connection strength in high-risk areas, while there is overdesign in low-risk areas. At the same time, the structural state of hydraulic structures is influenced by various factors such as material properties, construction quality, and service life. Different structural states can cause changes in the stress conditions of pull bolts, but traditional fixed spacing design methods cannot adjust according to the actual structural state, and cannot timely discover and solve the bolt connection problems caused by changes in the structural state, thereby affecting the safety and reliability of the structure. Furthermore, fixed bolt spacing design may cause unnecessary material waste and increase engineering costs. In some low-risk areas, excessive bolt arrangement is not only unnecessary, but also increases construction difficulty and cost. In high-risk areas, due to the excessive spacing of bolts, the structure may not meet the safety requirements, and post-reinforcement is needed, further increasing engineering costs and maintenance difficulty.

[0004] To solve the above problems, the present technical solution proposes a method for dynamically optimizing the spacing of pull bolts of hydraulic structures based on big data analysis. SUMMARY

[0043] Example 1

[0044] like Figures 1 to 3 As shown, this embodiment provides a method for dynamically optimizing the spacing of tension bolts in hydraulic structures based on big data analysis, which specifically includes the following steps:

[0045] S1. Acquire the concrete pouring data of the hydraulic structure, and simultaneously acquire the material and bolt conditions of the hydraulic structure;

[0046] In this embodiment, the concrete pouring condition data includes concrete pouring flow and flow velocity data corresponding to the installation location of the hydraulic structure, which is used to analyze the impact of average concrete pouring at the corresponding location on the corresponding structure. Past concrete pouring conditions are used to simulate future concrete pouring conditions to simulate and analyze the impact of the structure. The material conditions of the hydraulic structure include the connection strength of the materials and the damage of the connection. The connection strength of the materials is obtained to analyze whether the connection strength between the materials can withstand the impact of concrete pouring. If the connection strength can easily withstand the impact of concrete pouring, the tension bolts do not need to be set very densely. If the connection strength cannot withstand the impact of concrete pouring, the bolt setting density needs to be increased to strengthen the connection strength between the materials. In the process of increasing the bolt density, the fixing of the bolts will cause damage to the connection. Therefore, it is necessary to analyze the damage condition of the damaged connection at the bolt connection to evaluate the connection stability in order to select the best connection method.

[0048] In this embodiment, the concrete pouring impact hazard assessment in step S2 includes the following specific steps:

[0049] S21, obtain the water velocity corresponding to the concrete pouring, analyze the impact of the structure based on the average velocity of the concrete pouring at each point, the velocity and density of the concrete pouring corresponding to the concrete pouring can be obtained through sensors, for example, the density of the concrete pouring is obtained through a concrete pouring density sensor, the velocity of the concrete pouring is obtained through a corresponding concrete pouring velocity sensor, the velocity of the concrete pouring and the density of the concrete pouring are substituted into the concrete pouring impact force calculation formula to calculate the corresponding concrete pouring impact force, how to calculate the concrete pouring impact force through the velocity of the concrete pouring and the density of the concrete pouring is a conventional technique in the art, and the calculation formula is not shown here, and the concrete pouring impact force at each position on the edge of the hydraulic structure is obtained;

[0051] S3, connection risk assessment based on the material condition of the hydraulic structure and the bolt condition;

[0052] In this embodiment, the connection risk assessment based on the material condition of the hydraulic structure and the bolt condition in step S3 includes the following specific steps:

[0053] S31, obtain the damage condition data of the hydraulic structure in the process of bolt implantation corresponding to the connection strength, wherein the damage condition data includes the increase of cracks, and the connection damage analysis is performed on the damage condition data in the process of bolt implantation corresponding to the connection strength, wherein the damage analysis calculation formula is: Wherein n is the number of times of the hydraulic structure corresponding to the bolt implantation corresponding to the connection strength, sci is the increased crack area, sm is the total surface area of the connection, λ is the influence weight of the increased crack, the value range is 0.3-0.6, reflecting the influence of the material of the hydraulic structure, for example, the value of concrete is 0.6, and the value of steel is 0.3, and Sv is the defect abnormality of the connection, that is, the fragile abnormality of the connection at the initial time, which leads to more abnormal connection under the influence of bolt implantation, and more accurately reflects the sensitivity of the material to the crack, representing the average influence of the hydraulic structure corresponding to the bolt implantation corresponding to the connection strength, quantifying the direct damage caused by the bolt implantation, and reflecting the change of the structural fragility caused by the bolt implantation.

[0054] The above steps have the advantages that the cumulative damage effect of the bolt implantation operation on the structure is quantified, the influence of the material property difference on the crack sensitivity is considered, and the trend evaluation of the damage development is provided through historical data analysis;

[0058] The above steps have the advantages that the structural damage and the connection performance are organically combined, and the limitation of single index evaluation is avoided;

[0059] S4, analyze the distance between the pull bolts based on the concrete pouring impact danger evaluation and the connection danger evaluation;

[0060] In the embodiment, the bolt spacing analysis in step S4 is based on the concrete pouring impact risk assessment and the connection risk assessment, including the following specific contents:

[0061] S41, obtain the connection risk assessment result and the concrete pouring impact risk assessment result, multiply them to obtain the structure strength risk; the connection risk assessment reflects the structure risk caused by the loosening, damage or fatigue of the bolt connection; the concrete pouring impact risk assessment reflects the impact of the dynamic load of the concrete pouring on the structure; multiplication: emphasizes the nonlinear coupling effect of the two, that is, the connection problem may be amplified under the concrete pouring impact, when the connection state is poor, the concrete pouring impact may accelerate the structure damage, therefore, the product form can reflect the actual risk better than the linear superposition;

[0062] S42, obtain the structure strength risk and the corresponding set bolt spacing, divide the structure strength risk by the corresponding standard value of the structure strength risk to obtain the strength risk standard result, then divide the corresponding set bolt spacing by the strength risk standard result to obtain the corresponding bolt spacing analysis result, according to the strength risk standard result, adjust the bolt spacing reversely: high risk (large value) reduces the bolt spacing (increases the number of connection points); low risk (small value) can appropriately increase the bolt spacing (reduces the material cost, and reduces the damage to the structure in the connection process), according to the actual risk level, optimize the design, avoid the safety redundancy or deficiency caused by the fixed spacing;

[0063] S5, connect the structure based on the obtained bolt spacing analysis result.

[0064] In the embodiment, step S5 includes the following specific contents:

[0065] Obtain the bolt spacing analysis result, implant the bolt at the corresponding position according to the obtained bolt spacing analysis result, so as to connect the structure, for example, implant a bolt with a spacing of 5 cm at the corresponding position, then implant a bolt with a spacing of 5 cm at the position needing to be connected.

[0066] It should be noted that the setting parameters (such as each weighting weight and standard value) in the embodiment are obtained by the skilled person in the art through historical data experiments, and the specific experimental method is: obtaining at least five hundred groups of historical concrete pouring condition data of the position of the hydraulic structure, and simultaneously obtaining the material condition and bolt condition of the hydraulic structure, and simultaneously obtaining the bolt spacing condition, obtaining the result of whether the hydraulic structure can achieve the connection effect within the safe time, and simultaneously importing the historical data into the embodiment of the application to calculate the bolt spacing analysis result, and importing the bolt spacing analysis result and the corresponding bolt connection spacing condition of the connection effect within the safe time into the fitting software for data iterative fitting, and outputting the setting parameter value with the maximum judgment accuracy. It should be noted that the fitting software is preferably a matlab fitting software, and the advantages are: by collecting at least five hundred groups of historical concrete pouring condition, material condition, bolt condition, bolt spacing and connection effect result data of the hydraulic structure, the various complex conditions of the hydraulic structure in actual operation can be fully reflected, these data are derived from real historical cases and are highly consistent with the actual engineering scene, so that the setting parameters obtained based on these data can more accurately reflect the actual situation, improve the reliability of the bolt spacing analysis result, and the performance of the hydraulic structure is comprehensively affected by the concrete pouring, material, bolt and other factors, and there is a complex interaction between each factor. By analyzing a large amount of historical data, the complex relationship between these factors can be captured, for example, how the concrete pouring speed and direction jointly affect the bolt spacing and connection effect with the material properties and bolt performance. Traditional theoretical analysis may be difficult to consider all these complex relationships, while analysis based on actual historical data can more comprehensively and accurately grasp these relationships, so that the setting parameters are more accurate; the bolt spacing analysis result and the actual connection effect data are imported into the fitting software for iterative fitting, and the parameters are adjusted to improve the judgment accuracy. This iterative process can gradually optimize the setting parameters, so that they can better adapt to various situations, thereby obtaining a more accurate bolt spacing analysis model and reducing analysis errors caused by inaccurate parameters.

[0067] By running the steps of the embodiment, the following advantages are obtained: based on the concrete pouring condition data of the position of the hydraulic structure and the connection condition of the hydraulic structure, the concrete pouring impact risk is evaluated, based on the material condition and bolt condition of the hydraulic structure, the connection risk is evaluated, and based on the concrete pouring impact risk evaluation and the connection risk evaluation, the bolt spacing analysis is performed, which reduces unnecessary bolt quantity and damage to the structure during the connection process, ensures reinforcement in high-risk areas, and effectively improves the safety of the hydraulic structure construction process.
