Description

Technical Field

[0001] This invention relates to the field of rock geology and engineering technology or other related fields. Specifically, it relates to a method and apparatus for testing the rock's resistance to disintegration, as well as electronic equipment. Background Technology

[0002] Weathering alters the structure and properties of rocks, significantly impacting some of their engineering performance. Disintegration resistance, a measure of a rock's ability to resist weathering and erosion when exposed to water, is a crucial indicator for evaluating the degree and type of weathering, as well as its resistance to weathering. It is of great significance for assessing the engineering properties of weathered rocks, geological research, and engineering evaluation.

[0003] There are two main methods for testing the rock disintegration resistance index: laboratory testing and field testing. Laboratory testing simulates weathering processes to study the degree and type of weathering in rocks and evaluate their disintegration resistance. Methods include baking, vacuum testing, brine testing, freezing testing, chemical dissolution testing, and isothermal heating. Field testing directly evaluates the disintegration resistance of rocks within weathered zones. Using rock cores as test samples, direct observation combined with rock type and weathering degree determines the rock's disintegration resistance. Both laboratory and field testing methods have their advantages and disadvantages. Laboratory testing allows for precise control of the rock sample processing, while field testing allows for a comprehensive assessment of the rock's disintegration resistance under natural conditions.

[0004] Among related technologies, fully weathered and strongly weathered rocks are the most widely encountered rocks in engineering. Currently, rock and soil disintegration resistance testing methods are mainly for moderately and slightly weathered rocks and undisturbed soil, and there are no testing methods applicable to strongly weathered and fully weathered rocks. Current disintegration resistance testing methods are difficult to use for fully weathered and strongly weathered rocks, the testing procedures are relatively cumbersome, and the overall testing efficiency is low.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0033] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0034] The following embodiments of the present invention can be applied to various rock disintegration resistance testing systems / applications / equipment. The present invention tests the disintegration resistance of granular weathered rocks that cannot be prepared into block samples, determining the disintegration resistance of the entire grain size of the weathered rock. Simultaneously, the rock disintegration resistance testing method provided by the present invention ensures that the sample is fully immersed in water and disintegrates, preventing the sample from colliding and breaking during the test, which would lead to distorted results. Furthermore, the present invention provides a clear standard for the stability of weathered rocks upon contact with water, giving a disintegration evaluation index that comprehensively reflects the rock disintegration situation, as well as an evaluation index reflecting the changes in the engineering properties of the weathered rock after disintegration.

[0035] The present invention will now be described in detail with reference to various embodiments.

[0036] Example 1

[0037] According to an embodiment of the present invention, an embodiment of a method for testing the rock's resistance to disintegration is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0038] Figure 1 This is a flowchart of an optional rock disintegration resistance test method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0039] It should be noted that before conducting the disintegration resistance test on completely weathered or strongly weathered rock in this embodiment, appropriate instruments and tools need to be prepared for the test. For example, test sieves / analytical sieves, including coarse and fine sieves, are required. The aperture size of the test sieves / analytical sieves can be flexibly selected according to the particle size of the sample. The volume of each level of analytical sieve should ensure that the sample at each level can be included in the sieve for sieving. Simultaneously, a balance is prepared: 5000g (graduation value 1g); 1000g (minimum graduation value 0.1g); and 200g (minimum graduation value 0.01g). The choice of balance should be determined based on the amount of sample, and the ratio of the minimum graduation value of the balance to the mass of the weighed sample should be less than 1:5000. In addition, an oven, water tank, brush, tray, and thin rope are also required.

[0040] It should be noted that this embodiment allows for the planning of pore size grading standards for test sieves / analytical sieves. Analytical sieves are used to separate and measure weathered rock particles of different sizes. The selection of their pore sizes should cover the entire particle size range, from large to small, to ensure a comprehensive evaluation of the rock's resistance to disintegration. The analytical sieve pore size grading standards include: Coarse sieve pore sizes: 60mm, 40mm, 20mm, 10mm, 5mm, 2mm. These sieve openings are mainly used to separate large particles in the rock, ensuring that the test covers the coarse-grained components. The selection of these pore sizes is based on the distribution of the sample particle size to capture as much original rock structure information as possible. Fine sieve pore sizes: 1.0mm, 0.5mm, 0.25mm, 0.1mm, 0.075mm. These sieve openings are used for a more refined classification of the products after rock disintegration, especially for calculating the increase in mud content, which requires accuracy to a particle size less than 0.075mm to assess the amount of rock converted into mud. In practice, if the sample particle size distribution is very wide, it is advisable to increase the sieve aperture classification. For example, adding 30mm and 15mm aperture sieves to the coarse sieve, or 0.05mm and 0.02mm aperture sieves to the fine sieve, can more accurately measure the amount of mud formation and the post-disintegration particle distribution across different particle size ranges. However, increasing the sieve aperture classification requires consideration of experimental efficiency and cost, as well as whether it can significantly improve the accuracy of the test results. Additionally, for special rock types, such as those containing particularly hard or soft components, it may be necessary to adjust the sieve aperture standards. For example, adding finer sieve apertures can more accurately measure the total amount of mud formation after disintegration, or adding coarser sieve apertures can separate large, incompletely disintegrated rock fragments. In such cases, the aperture selection should be based on a thorough understanding of the rock characteristics and the need for accurate experimental results.

[0041] Then, sample collection and initial sample weighing are performed. Sample collection can refer to collecting fully weathered / strongly weathered rock samples in the field. After collection, the samples should be immediately sealed to retain moisture, and protected from vibration, sunlight, and freezing. Then, the bulk density (m³) of each level of test sieves is measured. i 'i' represents the sieve number for each test level. Select a certain number of representative samples for drying. The drying temperature can be chosen independently, for example, 105℃ (65℃ can be used if the sample contains volatile substances, such as carbonaceous rock). After drying, weigh the total mass of the samples, ma. Perform particle analysis using the sieve analysis method. Sampling and testing procedures can be based on the sieve analysis method in the "Standard for Geotechnical Testing Methods" (GB / T50123-2019). During sieve analysis, gently shake the analytical sieve; do not use a sieve shaker to vigorously shake the analytical sieve to avoid sample breakage. After sieve analysis, weigh the mass ma of the sample residue at each sieve level. i (i.e. ma 60 ma 40 ma 20 ma 10 ma5, ma2, ma0.5 ma 0.25 ma 0.075 The particle size distribution curve before the disintegration test was plotted using the data from the test (including the bottom sieve size (ma0)).

[0042] Step S101: Place the rock test sample into a test sieve, perform a disintegration test on the rock test sample according to predetermined experimental steps, and plot the rock particle distribution curve before disintegration and the rock particle distribution curve after disintegration. The predetermined experimental steps include at least: filling the water tank with water, weighing in water with a sieve, and rinsing with a predetermined water flow rate.

[0043] Optionally, the rock test specimens are subjected to a disintegration test through predetermined experimental steps, including: a specimen placement step: the rock test specimens are laid flat in the test sieves, the bottom layer of the sieve is removed, and different test sieves are stacked in order of sieve diameter from top to bottom; a water tank filling step: the entire set of test sieves is placed in the water tank, and then water is poured into the water tank until all test sieves are completely submerged; a specimen rinsing step: after the rock test specimens are soaked in water for a predetermined experimental time, the water in the water tank is drained, and starting from the top layer of test sieves, the rock test specimens on the test sieves are rinsed with water at a predetermined flow rate, and the test sieves are shaken to flush all particles smaller than the test sieves through the sieve mesh to the next level of test sieves; a water-with-sieve weighing step: the buoyant bulk density of each level of test sieves and the rock test specimens after rinsing is measured; and a repeated disintegration step: the specimen rinsing step is repeated, rinsing and weighing are performed once at predetermined experimental time intervals until the buoyant bulk density of the specimens is stable, thus confirming that the rock test specimens are in a disintegration-stable state.

[0044] The method of recording the specific time during the immersion of rock test samples is crucial, as it directly affects the accuracy and reliability of the disintegration test results. The moment immersion begins should be precisely recorded as the entire test sieve is placed in the water tank and water is slowly poured in until the sample is completely submerged. A timer accurate to the minute, such as a clock app on a mobile phone or a professional laboratory timer, should be used to record the moment the water first comes into contact with the sample. Simultaneously, the condition of the sample should be continuously monitored during immersion, especially in the first few immersion and disintegration cycles. Although the test requires the sample to stand for 12 hours, in practice, observations should be made at several key time points after the start of immersion, such as 1 hour, 3 hours, 6 hours, and 9 hours, to ensure that the sample does not exhibit abnormal reactions, such as excessively rapid disintegration or the generation of a large number of bubbles, which could affect the normal progress of the test. After the sample has stood for 12 hours, the precise time of the end of immersion needs to be recorded, again using a timer accurate to the minute, to ensure accurate correspondence with the start of immersion, facilitating the accurate execution of subsequent test steps.

[0045] It should be noted that the sample rinsing step mentioned in this embodiment also includes: when rinsing the sieve diameter of the bottom first-level test sieve, the fine particles are flushed through the sieve into the water tank.

[0046] Additionally, it should be noted that the repeated disintegration step also includes: stacking the weighed test sieves containing the rock test samples together in gradation order, immersing them in water, and repeating the sample rinsing step.

[0047] It should be noted that this embodiment requires repeated sample immersion. Therefore, it is necessary to record the immersion time for each cycle. That is, the start and end times of each immersion should be recorded during the repeated immersion disintegration cycle. Before the sample's buoyant density stabilizes, the start and end times of each 12-hour immersion cycle need to be accurately recorded to track the sample's changes and ensure data continuity and experimental controllability.

[0048] After the sample has disintegrated, a stability test is required. This is determined by two consecutive weighings where the difference in the buoyant bulk density of each sample is less than 0.1 g, or two consecutive weighings where the difference is less than 1%. These criteria determine whether the sample has completed disintegration. Upon reaching this standard, the final immersion time is recorded as the moment the sample has completed disintegration. Finally, the start and end times of each immersion are recorded in detail in the experimental log, including the date, time, sample condition description, and environmental conditions (such as temperature and humidity), to facilitate subsequent data analysis and experimental reproduction.

[0049] Additionally, it should be noted that this embodiment requires control of the water flow method for rinsing the sample to ensure the accuracy of the test and the integrity of the sample. This includes selecting the water source and regulating the water flow. When selecting the water source, a laboratory tap water system or a stable water source, such as a faucet or a dedicated water flow control device, can be used. When rinsing the sample, a low-velocity water flow should be used. This can be achieved in several ways: using a thin tube or nozzle connected to the water source to reduce the outlet area of ​​the water flow, thereby reducing the water flow velocity; installing a flow controller, such as a throttle valve, between the faucet and the test sieve to precisely regulate the water flow velocity; or using a water tank, introducing the water flow into the tank first, and then allowing the water to flow from the tank through the test sieve, controlling the water flow velocity through the size and shape of the tank. The water flow should slowly enter from the top of the test sieve containing the sample, avoiding direct rinsing of the sample as much as possible to minimize disturbance. If a water tank is used, ensure that the water level in the tank is controlled at an appropriate height so that the water flows smoothly through the test sieve, rather than creating turbulence. During rinsing, monitor the water flow rate to ensure that the sample on each sieve is thoroughly but gently rinsed, so that particles smaller than the sieve openings are moved to the next sieve or trough. A container can be used to measure the total amount of water passing through, ensuring that the water flow rate to each sample layer is approximately the same. The rinsing time needs to be controlled to ensure that the particles in the sample are completely carried away by the water flow, but not so long as to cause unnecessary abrasion to the particles. The rinsing time should be adjusted according to the sample volume and water flow rate, but excessively long rinsing should be avoided. After each rinse, check the remaining sample on each sieve to ensure that no particles have been missorted into an inappropriate sieve due to improper water flow control. If errors are found, sieving and rinsing should be repeated.

[0050] In addition, for the collection of fine particles, i.e., particles smaller than 0.075 mm in diameter, a collection device is required to ensure the accurate collection and analysis of this important data. The collection device provided in this embodiment may include: 1. A collection tank: Fine particles are mainly collected through the tank. The tank should be designed to be sufficiently large to accommodate the entire fine particle suspension after sample rinsing. The bottom of the tank should be flat and slightly inclined to facilitate the sedimentation and collection of fine particles. Graduation marks should be provided on the side of the tank for monitoring the water level and the volume of the suspension. 2. A filtration device: A filtration device is designed at the end of the tank. Its main function is to filter and collect fine particles smaller than 0.075 mm. It should be noted that the filtration device provided in this embodiment can be a replaceable filter screen with a mesh size smaller than the minimum analytical sieve aperture (0.075 mm) to ensure effective interception of fine particles. 3. A sedimentation zone: A sedimentation zone is designed downstream of the filtration device for fine particle sedimentation. 4. A collection container: A movable collection container is designed at the bottom of the sedimentation zone for the final collection of the settled fine particles. 5. Water Level Control Device: A water level control device is installed in the water tank. This can be an automatic water level sensor with a water valve, or a manual overflow outlet, to ensure a stable water level and prevent loss or mixing of fine particles due to water level fluctuations. 6. Sedimentation Auxiliary Equipment: A settling rack or settling area is provided to hold containers containing fine particle suspensions to promote sedimentation. In this embodiment, the settling area is equipped with temperature and humidity control modules to ensure the sedimentation process takes place in a stable environment. 7. Operation Panel and Indicators: An operation panel and indicators are installed on the collection device to display information such as water tank level, filter status, and collection container position, as well as to control parameters such as water flow rate and water level. The design should consider the cleanliness and maintenance of the device. The filter and collection container should be designed for easy disassembly and cleaning to ensure the device is clean before each experiment, avoiding residues from previous experiments from affecting the experimental results.

[0051] Optionally, the steps of plotting the rock particle distribution curve before and after disintegration include: placing the rock test sample into a perforated test sieve, performing particle analysis using a sieve analysis strategy, weighing the mass of each rock test sample after sieve analysis, and plotting the particle size distribution curve before the disintegration test; when the rock test sample is detected to be in a disintegration stable state, placing different rock test samples in the test sieve into an oven to dry, weighing the mass of each rock test sample, and plotting the particle size distribution curve after the disintegration test using the test data.

[0052] In this embodiment, after the rock test sample has disintegrated and stabilized, the samples on each sieve are placed in an oven to dry, and the mass of the remaining sample on each sieve is weighed (mb). iFor the sieve bottom mass mb0 less than 0.075 mm, it can be calculated by subtracting the total mass of the residue at each sieve level after disintegration from the total mass ma of the test before disintegration. The calculation determines the sieve bottom mass. Based on this experimental data, a particle size distribution curve was plotted after the disintegration test.

[0053] It should be noted that fine-grained soil particle size analysis is an important step in the testing method for evaluating the disintegration resistance of fully weathered rocks. It is used to analyze the composition of fine particles smaller than 0.075 mm produced during disintegration, thus providing a more comprehensive assessment of the rock's disintegration properties. When conducting fine-grained soil particle size analysis, a representative sample must first be selected from the fine particles precipitated in the water tank collected after the disintegration test. This ensures that the sample selection reflects the composition of the fine-grained soil after disintegration. The fine-grained soil sample is then placed in an oven and dried at 105-110℃ until the sample reaches constant weight to remove moisture. If the sample contains volatile substances, such as organic matter in carbonaceous rocks, the drying temperature can be appropriately reduced, such as to 65℃, to avoid altering the sample composition. After drying, place the fine-grained soil sample in a container, add an appropriate amount of dispersant, such as sodium hexametaphosphate (NaPO3) or a surfactant, and use a magnetic stirrer or ultrasonic disperser to fully disperse the sample, ensuring uniform dispersion of fine particles and preventing agglomeration. Then, use a laser diffraction particle size analyzer. Add the dispersed fine-grained soil sample to the sample chamber of the laser diffraction particle size analyzer. The instrument will automatically measure the particle size distribution and generate a particle size distribution curve. Plot the fine-grained soil particle size distribution curve and compare it with the distribution curve before the disintegration test to visually demonstrate the changes in the fine-grained soil composition before and after rock disintegration.

[0054] Specifically, when plotting the rock particle distribution curve (before and after disintegration), create a new worksheet in the software and input the particle size distribution data before and after disintegration into the table in the format of particle size and mass percentage. Then select the data range, click "Insert" → "Scatter Plot" or "Line Plot" to create the chart. Ensure that the X-axis (horizontal axis) represents the logarithm of particle size and the Y-axis (vertical axis) represents the mass percentage of particles smaller than a certain size. Then adjust the ratio of the X-axis and Y-axis to ensure that the length of 50% of the vertical axis corresponds to one order of magnitude of the length of the horizontal axis. Add a title, legend, and data labels to make the chart clearer and easier to understand. Alternatively, professional charting software can be used to plot the distribution curve. For example, using Orgin or MATLAB, the data from the disintegration test can be imported into the professional charting software. Ensure that the data format is correct, select the appropriate chart type (scatter plot, line plot), customize the X-axis and Y-axis parameters, including logarithmic scale, axis range and axis labels, use the software's built-in curve fitting function to fit the particle distribution curve, and then use the integration tool to calculate the area under the curve.

[0055] Figure 2 This is a schematic diagram illustrating the particle size distribution curves before and after disintegration according to an embodiment of the present invention, as shown below. Figure 2 As shown, the vertical axis represents the percentage of weathered rock particles smaller than a certain size, and the horizontal axis represents the logarithm of the particle size. The ratio of the horizontal axis to the vertical axis should be such that 50% of the length of the vertical axis corresponds to one order of magnitude of the length of the horizontal axis. Curve a shows the particle size distribution before disintegration, and curve b shows the particle size distribution after disintegration.

[0056] The following provides a specific method for sample disintegration and weighing experiments.

[0057] 1) Spread the sample evenly in the sieve, avoiding stacking as much as possible. Then remove the bottom sieve and stack the test sieves in order of diameter from top to bottom. Place the entire set of test sieves into the water tank and pour in pure water until the test sieves are completely submerged. Record the time when the sample begins to be immersed in water, accurate to the minute.

[0058] 2) After soaking the sample in water for 12 hours, drain the water from the tank. Starting from the top layer of test sieves, rinse the sample on the test sieves with a low flow rate of water, shaking the sieves to flush all particles smaller than the test sieve through the screen to the next level of test sieve. When rinsing the bottom level sieve (0.075mm), flush the fine particles through the screen into the water tank.

[0059] 3) Weigh the overall buoyant density m of each grade (sieve + sample) after rinsing. Stack the weighed analytical sieves with the sample together in gradation order, immerse them in water, and repeat step 2).

[0060] 4) Rinse and weigh every 12 hours until the buoyant density of the sample stabilizes, at which point the sample is considered to have completely disintegrated. The stabilization standard is that the difference in buoyant density between two consecutive weighings of each grade of sample is less than 0.1g, or the difference in buoyant density between two consecutive weighings is less than 1%.

[0061] 5) After the disintegration has stabilized, place the samples on each sieve into an oven to dry, and weigh the mass of the remaining samples on each sieve (mb). i (i.e. mb 60 mb 40 mb 20 mb 10 mb5, mb2, mb 0.5 mb 0.25 mb 0.075 For the sieve bottom mass mb0 less than 0.075 mm, it can be calculated by subtracting the total mass of the residue at each sieve level after disintegration from the total mass ma of the test before disintegration. The calculation determines the sieve bottom mass. Based on this experimental data, a particle size distribution curve was plotted after the disintegration test.

[0062] Step S102: Calculate the integral area of ​​the weathered rock before disintegration based on the rock particle distribution curve before disintegration, and calculate the integral area of ​​the weathered rock after disintegration based on the rock particle distribution curve after disintegration.

[0063] Figure 3 This is an optional integral area S of weathered rock grain size before disintegration test according to an embodiment of the present invention. A The schematic diagram shows the particle size distribution curve. The particle size integral area S is calculated as follows: S is the area enclosed by the particle distribution curve a, the horizontal line A1O representing 100% particle size by mass percentage, and the vertical line OA2 (0.075 mm). A ;and Figure 4 This is an optional integral area S of weathered rock grain size after a disintegration test according to an embodiment of the present invention. B A schematic diagram.

[0064] Step S103: Calculate the equivalent rock disintegration resistance index based on the curve integral area before and after the weathered rock disintegrates.

[0065] Rock disintegration resistance is characterized by the rock's disintegration rate (disintegration resistance index). The disintegration rate is the ratio of the mass difference of a sample before and after disintegration under specified conditions to the initial mass of the sample. The disintegration resistance index is the ratio of the rock's disintegration rate to the standard disintegration rate of completely weathered or strongly weathered rocks.

[0066] For example, the equivalent rock disintegration resistance index can be calculated using the following formula:

[0067]

[0068] In the formula I 0.075 — Rock equivalent disintegration resistance index (%), calculated with an accuracy of 0.1.

[0069] S A —The integral area (mm) of the curve for particles larger than 0.075 mm in diameter before the weathered rock disintegrates, with a calculation accuracy of 0.01 mm.

[0070] S B —The integral area (mm) of the curve for particles larger than 0.075 mm after weathering rock disintegration, with a calculation accuracy of 0.01 mm.

[0071] Through the above steps, rock test samples can be placed in a test sieve, and disintegration tests can be performed on the rock test samples according to predetermined experimental steps. The rock particle distribution curves before and after disintegration are plotted. Based on the pre-disintegration rock particle distribution curve, the integral area of ​​the curve before disintegration is calculated, and the integral area of ​​the curve after disintegration is calculated. Based on the integral areas of the curve before and after disintegration, the equivalent disintegration resistance index of the rock is calculated. The predetermined experimental steps include at least: filling a water tank with water, weighing in water with a sieve, and rinsing with a predetermined water flow rate. In this embodiment, it is possible to ensure that the weathered rock sample fully absorbs water and disintegrates, allowing for the testing of disintegration resistance of granular weathered rock that cannot be formed into block samples. The disintegration resistance of the entire grain size group of weathered rock is determined, and the particle disintegration is evaluated across the entire particle size range, thereby solving the technical problem in related technologies where it is impossible to perform disintegration resistance tests on strongly weathered and completely weathered rocks.

[0072] Optionally, the test method for rock disintegration resistance also includes: obtaining the mass of particles smaller than the minimum sieve opening after disintegration and the total mass of the sample before disintegration; and calculating the total amount of mudification from rock disintegration based on the mass of particles smaller than the minimum sieve opening after disintegration and the total mass of the sample before disintegration.

[0073] Optionally, the test method for rock disintegration resistance also includes: obtaining the particle size mass below the minimum sieve aperture before disintegration, the particle size mass below the minimum sieve aperture after disintegration, and the total mass of the sample before disintegration; and calculating the mudification increment of rock disintegration based on the particle size mass below the minimum sieve aperture before disintegration, the particle size mass below the minimum sieve aperture after disintegration, and the total mass of the sample before disintegration.

[0074] Based on the selected analytical method, the obtained fine-grained soil particle size distribution data, including particle size, quantity, and mass ratio, were compiled. The analytical results were compared with the data before the disintegration test, and the mud accumulation increment was calculated—the percentage of newly added fine-grained soil component after disintegration relative to the total mass of the sample before disintegration—to assess the degree of fine particle production from rock disintegration. Combined with the calculation of total mud accumulation, the overall changes in fine-grained soil particles after rock disintegration were analyzed, including changes in particle size distribution and the increase in fine particle content. This data will help determine the rock's resistance to disintegration and the changes in its engineering properties after disintegration.

[0075] For example, the total amount of mudification n from rock disintegration can be calculated using the following formula. 0.075 :

[0076]

[0077] In the formula n 0.075 —Total mudification from rock disintegration (%), calculated to an accuracy of 0.1;

[0078] mb0 — Mass of particles smaller than 0.075 mm after disintegration (sieve bottom mass);

[0079] ma — Total mass of the sample before disintegration (g).

[0080] Calculate the mudification increment n′ of rock disintegration using the following formula. 0.075 :

[0081]

[0082] In the formula n′ 0.075 —Increase in mud formation due to rock disintegration (%), calculated to an accuracy of 0.1;

[0083] mb0 — the mass of particles smaller than 0.075 mm after disintegration, i.e.

[0084] ma0 — the mass of particles smaller than 0.075 mm before disintegration (sieve bottom mass);

[0085] ma — Total mass of the sample before disintegration (g).

[0086] It should be noted that the initial mass of particles smaller than 0.075 mm in the sample is ma0, and the mudification increment is the increase based on this.

[0087] When it is necessary to determine the equivalent disintegration index, a curve should be plotted; if only the amount of mud or the increase in mud is measured, a curve does not need to be plotted.

[0088] The rock disintegration resistance test method provided in this embodiment can comprehensively reflect the overall disintegration of particles at all levels, as well as the condition of the particles after disintegration, with an equivalent disintegration resistance index n. 0.075 The overall particle size change is reflected by the ratio of particle size integral area before and after disintegration. In actual engineering construction, in addition to considering the rock's resistance to disintegration, the state of the rock after disintegration is also important. For example, carbonaceous mudstone in a canal's horse path hub disintegrates into silty clay, while silty mudstone disintegrates into coarse sand, exhibiting completely different engineering properties. The total amount of mudification and the increase in mudification reflect the change in the content of fine particles (less than 0.075 mm) after disintegration. The amount of fine particles determines the engineering characteristics of weathered rock, and this is used to reflect the degree of influence of disintegration on the engineering properties of weathered rock.

[0089] In this embodiment, weathered rock samples were used for simulation testing. The test indicators can well reflect the disintegration resistance of different weathered rocks. For example, both strongly weathered carbonaceous mudstone and completely weathered sandstone have disintegration properties, but after disintegration, sandstone is sandy (mudization increase of 15%), while carbonaceous mudstone is clayy (mudization increase of 60%). The engineering properties of the two after disintegration are very different.
