[0002] In the relevant technology, the roadbed is the foundation of the highway. Using slag to fill the roadbed is one of the important measures to implement green highway construction and achieve a balance between excavation and filling. However, the mechanical properties of slag materials are very uneven, which has a serious impact on the compaction of the filled roadbed. Compaction is one of the key indicators for roadbed and pavement construction quality inspection, which characterizes the density after on-site compaction. The higher the compaction, the better the overall performance of the material. Currently, the commonly used on-site compaction measurement methods include direct methods (pit digging and sand filling method, ring knife method, etc.) and indirect methods (nuclear density meter method, non-nuclear density meter method). Although they are the most important methods for roadbed construction quality inspection, these methods are usually labor-intensive and time-consuming, and the detection accuracy is not high.

[0003] In summary, the technical problems existing in the relevant technologies need to be improved. Summary of the Invention

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0047] Before describing the embodiments of the present application in detail, some of the nouns and terms involved in the embodiments of the present application are first explained. The nouns and terms involved in the embodiments of the present application are subject to the following interpretations:

[0048] Sludge refers to a mixture of crushed rock and soil produced through blasting and other engineering methods. Sludge is widely used in roadbed filling, offering low cost and environmental benefits. For example, a pilot project in one region using lime soil as a substitute for sludge reduced costs by nearly 20% while also improving road quality.

[0049] The gradation curve visually displays the distribution characteristics of particles by corresponding the horizontal axis (particle size) with the vertical axis (the mass percentage of particles smaller than a certain particle size). The horizontal axis is usually on a logarithmic scale (such as sieve size), and the vertical axis is the cumulative percentage.

[0050] Preconsolidation loading is a method used in civil engineering to accelerate soil consolidation by pre-applying a load. The principle is based on Terzaghi's one-dimensional consolidation theory, which states that under the action of a building load, pore water gradually drains, reducing the pore volume and gradually consolidating the soil, increasing its strength.

[0051] In related technologies, the roadbed is the foundation of the highway. Using slag to fill the roadbed is one of the important measures to implement green highway construction and achieve a balance between cut and fill. However, the mechanical properties of slag materials are very uneven, which has a serious impact on the compaction of the filled roadbed. Compaction is one of the key indicators for testing the quality of roadbed and pavement construction. It represents the density condition after on-site compaction. The higher the compaction, the better the overall performance of the material. Currently, the commonly used on-site compaction measurement methods include direct methods (pit digging and sand filling method, ring knife method, etc.) and indirect methods (nuclear density meter method, non-nuclear density meter method). Although they are the most important methods for roadbed construction quality inspection, their inherent defects are becoming increasingly significant, mainly reflected in the limitations of practical application. The pit digging and sand filling method is difficult to test, its accuracy is difficult to guarantee, and it is labor-intensive and time-consuming. A typical problem is that it can only be sampled for testing, which is extremely limited in representativeness. If there is a large change in the material properties within the interval, it is easy to miss detection or measurement. The deflectometer has a small test range and cannot truly reflect the load condition. The non-nuclear density meter has large errors and unclear mechanical significance. The elastic wave measurement method has poor accuracy and is difficult to quantify. The limitations of the methods commonly used to determine the dry density of fine-grained soil have become increasingly apparent. For coarse-grained slag fill roadbed, it is even more difficult to ensure the test accuracy of the dry density.

[0052] In view of this, the embodiments of the present application provide a method and device for analyzing compaction parameters of slag, an electronic device, and a storage medium, which can effectively reduce the efficiency of determining slag parameters and improve the accuracy of determination.

[0053] The method for analyzing the compaction parameters of slag provided in the embodiment of the present application relates to the technical field of highway subgrade compaction detection. The method for analyzing the compaction parameters of slag provided in the embodiment of the present application can be applied to a terminal, can be applied to a server, or can be software running in a terminal or a server. In some embodiments, the terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, and a vehicle-mounted terminal, etc., but is not limited thereto; the server side can be configured as an independent physical server, or as a server cluster or distributed system composed of multiple physical servers, or as a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The server can also be a node server in a blockchain network; the software can be an application that implements the method for analyzing the compaction parameters of slag, etc., but is not limited to the above forms.

In a distributed computing environment, program modules can be located in local and remote computer storage media, including storage devices.

[0055] The following is a detailed description of the embodiments of the present application with reference to the accompanying drawings:

[0056] Figure 1 This is an optional flow chart of the method for analyzing compaction parameters of slag provided in the embodiment of the present application. Figure 1 The method may include but is not limited to steps S110 to S150:

[0057] Step S110: Screening the slag to be processed on site using a vibration screening tester to obtain a gradation curve corresponding to the slag to be processed on site;

[0058] Step S120: Using a vibration testing machine, compact the untreated on-site slag corresponding to each gradation in the gradation curve in the steel drum, and applying a load to the untreated on-site slag in the treated steel drum using a universal testing machine to obtain the apparent deformation modulus under different gradations, wherein the apparent deformation modulus is calculated from the stress increment and the strain increment;

[0059] Step S130: applying loads to the slag to be treated in the steel drum multiple times using a universal testing machine to obtain a correlation between the number of loading times and the apparent deformation modulus;

[0060] Step S140: Performing compaction tests of different stress paths on the on-site slag to be treated with the same gradation using a universal testing machine to obtain the variation pattern of the apparent deformation modulus under different stress paths;

[0061] Step S150: Analyze the compaction parameters of the on-site slag to be processed based on the apparent deformation modulus under different gradations, the correlation between the number of loading passes and the apparent deformation modulus, and the variation pattern of the apparent deformation modulus under different stress paths.

[0062] It is understood that the testing process of this embodiment requires the use of a universal testing machine, a steel drum, and a vibration testing machine. The steel drum can be a specially made drum, the hardness and size of which are appropriate for the current testing scenario. The vibration screening testing machine includes a vibrator and a mesh screen, on which the on-site slag to be processed is placed. The vibrator vibrates the mesh screen at a preset frequency, causing the mesh screen to screen the on-site slag to obtain slag of different particle sizes. Specifically, the mesh screen can include grid screens of different sizes.

[0063] In this embodiment, first, the field test soil is taken as the on-site slag to be processed to carry out an indoor compaction test, and the slag filler is first vibrated and sieved using a vibrator and a grid screen to obtain the particle size content of the on-site slag to be processed, and then a gradation curve is drawn according to the slag content under each particle size. Specifically, after obtaining the gradation curve, the on-site slag to be processed is mixed and placed in a customized steel barrel, and the on-site slag filler in the steel barrel is compacted by a vibration testing machine, and then a compression test is directly carried out using a universal testing machine, that is, the on-site slag to be processed in the steel barrel after vibration is applied by the universal testing machine. The corresponding stress and strain are then obtained by a computer and a sensor, and the ratio of the stress increment to the strain increment in the test is defined as the apparent deformation modulus. Among them, each group of gradations is unloaded after the load is applied, and the compressed slag material is screened and remixed as the next compaction material to continue to be loaded with the same load to obtain the apparent deformation modulus under different gradations. It can be understood that this embodiment simultaneously conducts compaction tests and direct shear tests under the above-mentioned different gradations in accordance with the "Geotechnical Code" to obtain the compaction degree and shear strength rules under different gradations, and compares them with the above-mentioned indoor compaction experiments.

[0064] In this embodiment, a universal testing machine is used to apply a load to the on-site slag to be processed in the steel drum. After unloading, no screening and vibration treatment is performed. After determining that the on-site slag to be processed in the steel drum is stable, a second load is applied. After repeating the operation for a preset number of times, the correlation between the number of loading times and the nominal deformation modulus is obtained. The preset number of times can be 10 times or 15 times, and can be adjusted according to actual conditions. Specifically, the relationship between different loading times (Number of times) and the nominal deformation modulus (Nominal Deformation Modulus) under indoor tests is as follows: Figure 2 As shown in the figure, the curves of different rolling times and compaction degree in the field test are as follows Figure 3 shown.

[0065] In addition, this embodiment will also take another group of slag materials with the same grade to conduct compaction tests with different stress paths, and obtain the apparent deformation modulus law under different stress paths as follows: Figure 4 As shown in the figure, the compacted slag material was used to conduct scanning electron microscope experiments and direct shear tests to verify the law of slag pore area ratio and shear strength under different stress paths.

[0066] Finally, the geometric similarity method was used to analyze the mechanical properties of slag under different gradations, and the results were obtained: Figure 5 It can be seen that the theoretical values ​​obtained using the geometric similarity method follow a consistent pattern of variation with the experimental values ​​obtained from laboratory tests. The larger the difference between particle size and number of passes, the greater the error, but the error maintains a certain linear pattern. After correcting the error through multiple sets of tests, the geometric similarity method can be used to simulate and derive field test results from small-particle laboratory tests. This demonstrates the rationality of this method of simulating field tests using laboratory tests. Comparative verification through various tests, engineering practices, and theoretical analysis confirms the reliability of this calibration method, which can accurately evaluate roadbed strength and effectively reflect the quality of roadbed construction.

[0067] By comparing the indoor and outdoor tests, it can be seen that the method of the embodiment of the present application can be verified by the following aspects:

[0068] Reliability: The accuracy was verified by comparing the measured values ​​with the compaction test, direct shear test, and scanning electron microscope test, and the same rule was obtained: the apparent deformation modulus in the compaction test decreases with the decrease of coarse particles and the increase of fine particles in the gradation, and the compaction degree and shear strength also meet this rule; the compaction experiment showed that the apparent deformation modulus reaches stability after about 7 loading times, and the optimal compaction number should be around 7-10 times. Similar conclusions were also drawn in engineering practice for the expansion and reconstruction project of the pre-set highway section. The roadbed reached the optimal dense state after 10 rollings; the variation law of the apparent deformation modulus obtained through compaction tests for different stress paths under the same gradation is consistent with the electron microscope scanning pore area and shear strength law. The results can reasonably predict the apparent deformation modulus under different stress paths. Specifically, the corresponding formula for the variation law of the apparent deformation modulus under different stress paths is as follows:

[0069]

[0070] Among them, K at =17σ re +2.45σ pre , σ pre represents the preconsolidation load; σ re represents the reload load; E represents the apparent deformation modulus; K at It represents the final apparent deformation modulus when the reload load exceeds 1.5 times the pre-consolidation load, K st Represents the effect of preconsolidation load on the peak modulus.

[0071] Advancedness: It can conduct rapid and remote testing, effectively improving the efficiency of soil compaction detection, thereby alleviating the practical contradiction between filling construction quality detection and rapid mechanized construction, and overcoming the shortcomings of traditional detection methods such as few sampling points, slow detection speed, high cost, and large interference with construction. This invention establishes the relationship between compaction effects under different compaction parameters and different gradations, improves the accuracy and scope of application of this calibration method, and greatly improves detection efficiency.

[0072] Operability: General geotechnical test methods have strict requirements on particle size or require specialized large-scale testing equipment. This calibration method has a wider range and is simpler, with lower maintenance costs and does not require professional personnel to operate.

[0073] Economical: There is no need for large-scale excavation to damage the roadbed, which reduces the cost and time of later repairs and the labor cost of professional inspections. It can be operated indoors without affecting the overall project progress and has low maintenance costs.

[0074] Compared with traditional detection and compaction methods, the method of the embodiment of the present application is simple and fast to operate, improves detection efficiency, and has accurate detection results, ensuring the quality and stability of the roadbed structure. It has low cost and good economic benefits, reduces the cost, time and dependence on equipment for later repairs, and has strong environmental adaptability and can be tested remotely to understand on-site construction. The method of the embodiment of the present application will not interfere with the roadbed construction and affect the construction progress. It can be applied to complex geological conditions or a large particle size range, and has strong active guidance through theoretical guidance.

[0075] In addition, the method of the embodiment of the present application has good adaptability and is very flexible in the selection of compacted materials. It can maintain stable performance under different climatic conditions and construction sites, reduce the dependence on professionals and professional equipment, and achieve convenient and rapid monitoring without affecting roadbed construction. The accuracy and reliability of the method of the embodiment of the present application have been verified through a large number of tests and engineering practices. The method of the embodiment of the present application has good stability, provides scientific knowledge for roadbed construction, helps to optimize construction plans, and improves construction quality and efficiency.
