Description

Technical Field

[0001] The present invention relates to the field of rock geological engineering technology or other related fields, and in particular to a method and device for testing the resistance of rock disintegration, and electronic equipment. Background Art

[0002] Under the action of weathering, the structure and properties of rocks will change, which has an important impact on some engineering properties of rocks. Disintegration resistance is a manifestation of the ability of rocks to resist weathering erosion when exposed to water. It is an important indicator for evaluating the degree and type of rock weathering, and is also an indicator for evaluating the ability of rocks to resist weathering. It is of great significance to the evaluation of engineering properties of weathered rocks, geological research and engineering evaluation.

[0003] The test methods of rock disintegration resistance index are divided into indoor test method and field test method. The indoor test method is to study the weathering degree and weathering type of rock under weathering through experiments simulating weathering, and evaluate the disintegration resistance of rock. The test methods include baking method, vacuum method, brine method, freezing method, chemical dissolution method and isothermal heating method. The field test method is to directly evaluate the disintegration resistance of rock in the weathering zone. The field core is used as the test sample. After direct observation, the rock type and weathering degree are combined to judge the disintegration resistance of the rock. The indoor test method and the field test method each have their advantages and disadvantages. The indoor test method can accurately control the rock sample processing process, and the field test method can comprehensively judge the disintegration resistance of the rock through the disintegration resistance of the rock under natural conditions.

[0004] In the relevant technologies, fully and strongly weathered rocks are the most common rocks encountered in engineering. At present, the test methods for rock and soil disintegration resistance are mainly for medium and slightly weathered rocks and undisturbed soil tests, and there is no test method suitable for strongly weathered and fully weathered rocks. At present, the disintegration resistance test method is difficult to complete the disintegration resistance test of fully and strongly weathered rocks, the test process is relatively cumbersome, and the overall test efficiency is low.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0034] The following embodiments of the present invention can be applied to various rock disintegration resistance testing systems / applications / equipment. The present invention conducts a disintegration resistance test on granular weathered rock that cannot be made into block samples, and determines the disintegration resistance of the entire grain group of weathered rock. At the same time, the rock disintegration resistance test method provided by the present invention can ensure that the sample is fully immersed in water and disintegrated, and prevent the samples from colliding and breaking with each other during the test process, resulting in distorted results. In addition, the present invention provides clear stability standards for weathered rock disintegration when exposed to water, and provides disintegration evaluation indicators that can comprehensively reflect the rock disintegration situation, as well as evaluation indicators that reflect the changes in the engineering properties of weathered rock after disintegration.

[0035] The present invention is described in detail below in conjunction with various embodiments.

[0036] Embodiment 1

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

[0038] Figure 1 is a flow chart of an optional method for testing rock disintegration resistance according to an embodiment of the present invention, such as Figure 1 As shown, the method comprises the following steps:

[0039] It should be noted that, before the disintegration resistance test of fully weathered rock or strongly weathered rock is carried out in this embodiment, it is necessary to prepare corresponding instruments and tools for the test, for example, prepare a test sieve / analysis sieve, including: a coarse sieve and a fine sieve. When selecting the aperture of the test sieve / analysis sieve, it can be flexibly selected according to the coarseness of the sample particles, and the volume of the analysis sieves at each level should ensure that the samples at each level can be included in the sieve for screening. At the same time, prepare a balance: weigh 5000g (division value 1g); weigh 1000g (minimum division value 0.1g); weigh 200g (minimum division value 0.01g). The selection of the balance should be determined according to the amount of the sample, and the ratio of the minimum division value of the balance to the mass of the weighed object should be less than 1:5000. In addition, it is also necessary to prepare an oven, a sink, a brush, a tray, a string, etc.

[0040] It should be noted that the aperture classification standards of the test sieve / analytical sieve can be planned in this embodiment. The analytical sieve is used to separate and measure weathered rock particles of different particle sizes. The selection of its aperture should cover the entire particle size range, from large to small, to ensure that the rock's resistance to disintegration can be fully evaluated. The aperture classification standards of the analytical sieve include: coarse sieve aperture classification: 60mm, 40mm, 20mm, 10mm, 5mm, 2mm. These sieve holes are mainly used to separate large particles in the rock to ensure that the test can cover the coarse-grained components in the rock. The selection of these apertures is based on the distribution of the sample particle size to capture as much original rock structure information as possible. Fine sieve aperture classification: 1.0mm, 0.5mm, 0.25mm, 0.1mm, 0.075mm. These sieve holes are used to more finely divide the products after rock disintegration, especially the calculation of mud increment, which needs to be accurate to a particle size less than 0.075mm to evaluate the amount of rock converted into mud. In specific operations, if the particle size distribution of the sample is very wide, you can consider increasing the sieve aperture classification, such as adding 30mm and 15mm sieves in the coarse sieve, or adding 0.05mm and 0.02mm sieves in the fine sieve, so as to more accurately measure the mud content of different particle size segments and the particle distribution after collapse. However, the increase in the sieve aperture classification needs to take into account the efficiency and cost of the test, as well as whether it can significantly improve the accuracy of the test results. In addition, for special rock types, such as rocks containing particularly hard or soft components, it may be necessary to adjust the sieve aperture standard, such as adding finer sieve apertures to more accurately measure the total amount of mud after collapse or adding coarser sieve apertures to separate large pieces of incompletely collapsed rock. In this case, the choice of aperture should be based on a full understanding of the rock properties and the need for accuracy of the experimental results.

[0041] Then, the sample is collected and the initial mass of the sample is weighed. When collecting the sample, it can refer to taking fully weathered rock / strongly weathered rock samples in the field. After collecting the sample, it is immediately sealed to retain water, prevent vibration, sun and frost. Then weigh the floating density of each level of test sieve ms i , i represents the number of each level of test sieve. Select a certain number of representative samples for drying. The drying temperature here can be selected by yourself. For example, select 105℃ for drying (when the sample contains volatile substances, such as carbonaceous rock, 65℃ can be selected). After drying, weigh the total mass ma of the sample. Perform particle analysis by sieving analysis. The sampling and test steps can be based on the particle analysis test sieving analysis method in the "Standard for Geotechnical Test Methods" (GB / T50123-2019). During the sieving process, shake the analysis sieve gently. Do not use a sieve shaker to shake the analysis sieve vigorously to avoid breaking the sample. After sieving, weigh the mass ma of the sieve residue samples at each level. i (i.e. ma 60 、ma 40 、ma 20 、ma 10 ,ma5,ma2,ma0.5 、ma 0.25 、ma 0.075 , and sieve bottom ma0), and use this test data to draw the particle size distribution curve before disintegration test.

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

[0043] Optionally, the rock test sample is subjected to a disintegration test through predetermined experimental steps, including: a sample placement step: laying the rock test sample in the test sieve flat, removing the bottom sieve, and stacking different test sieves in order from top to bottom according to the size of the sieve; a water tank water filling step: placing the whole set of test sieves into the water tank, and then injecting water into the water tank until all the test sieves are completely submerged; a sample flushing step: after soaking the rock test sample in water for a predetermined experimental time, draining the water in the water tank, starting from the top test sieve, flushing the rock test sample on the test sieve with running water at a predetermined flow rate, shaking the test sieve, and flushing all particles smaller than the test sieve through the sieve into the next test sieve; a weighing step with sieve in water: weighing the floating bulk density of each level of test sieve and the rock test sample after flushing; repeating the disintegration step, repeating the sample flushing step, flushing and weighing once at intervals of a predetermined experimental time, until the floating bulk density of the sample is stable, and determining that the rock test sample is in a disintegration stable state.

[0044] Among them, the specific time recording method is crucial in the process of immersing the rock test specimens, because it directly affects the accuracy of the disintegration test and the reliability of the results. When the whole set of test sieves is placed in the water tank and water is slowly injected until the specimen is completely submerged, the time point of the start of immersion should be accurately recorded. Use a timer accurate to the minute, such as the clock application in the mobile phone, a professional laboratory timer to record the moment when the water starts to contact the specimen. At the same time, during the immersion process, the state of the specimen should be continuously monitored, especially in the first few immersion and disintegration cycles. Although the test requires the specimen to stand for 12 hours, in actual operation, it should be observed 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 specimen has no abnormal reaction, such as too fast disintegration or a large number of bubbles, etc. These abnormalities may affect the normal progress of the test. After the specimen has been standing for 12 hours, the exact time of the end of immersion needs to be recorded, and a timing tool accurate to the minute is also used to ensure that it corresponds accurately to the start of immersion, so as to facilitate the accurate execution of subsequent test steps.

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

[0046] It should also be noted that when performing the repeated disintegration step, it also includes: stacking the weighed test sieves with the rock test samples in the order of grading, immersing them in water, and repeating the sample washing step.

[0047] It should be noted that this embodiment requires repeated sample immersion, so it is necessary to record the time of cyclic immersion, that is, when repeating the immersion disintegration cycle, the start and end time of each immersion should be recorded. Before the buoyant density of the sample is stable, the start and end time of each cycle of 12-hour immersion needs to be accurately recorded to track the change process of the sample and ensure the continuity of the data and the controllability of the experiment.

[0048] After the sample is disintegrated, a stable state judgment is required, including the difference in the floating bulk density of each level of sample weighed twice in a row is less than 0.1g, or the difference in the floating bulk density of the sample weighed twice in a row is less than 1%, which is the standard for judging whether the sample has completed disintegration. When this standard is reached, the final immersion time point is recorded as the moment when the sample completes disintegration. Finally, the start and end time of each immersion is recorded in detail in the experimental log, including date, time, sample state description, environmental conditions (such as temperature, humidity) and other information, to facilitate subsequent data analysis and experimental reproduction.

[0049] It should also be noted that the present embodiment needs to control the water flow mode of flushing the sample to ensure the accuracy of the test and the integrity of the sample, including selecting a water source and realizing water flow regulation. In the process of selecting a water source, the laboratory tap water system or a stable water source, such as a faucet or a special water flow control device, can be used. When flushing the sample, a low flow rate should be used. The specific operation can be achieved in the following ways: using a thin tube or nozzle to connect the water source to reduce the outlet area of ​​the water flow, thereby reducing the water flow rate; installing a flow controller, such as a throttle valve, between the faucet and the test sieve to achieve precise regulation of the water flow rate; using a water tank, first introducing the water flow into the water tank, and then letting the water flow through the test sieve from the water tank, and controlling the water flow rate by the size and shape of the water tank. The water flow should flow slowly from the upper part of the test sieve where the sample is located, and try to avoid directly flushing the sample to reduce the disturbance to the sample. If a water tank is used, it should be ensured that the water level of the water tank is controlled at an appropriate height so that the water flow can flow smoothly through the test sieve instead of forming turbulence. During the rinsing process, monitor the water flow rate to ensure that the sample on each layer of sieve is fully but gently rinsed so that particles smaller than the mesh size of that layer are moved to the next layer of sieve or to the sink. A container can be used to measure the total amount of water passing through to ensure that each layer of sample receives approximately the same amount of water flow. During the rinsing process, the rinsing time needs to be controlled to ensure that the particles in the sample are completely carried down by the water flow, but not so long that unnecessary wear and tear is caused to the particles. The rinsing time should be adjusted according to the sample size and water flow rate, but rinsing for too long should be avoided. After each rinse, check the residual samples at each level to ensure that no particles are misclassified into the inappropriate sieve due to improper water flow control. If errors are found, re-screening and rinsing should be performed.

[0050] In addition, for the collection of fine particles, that is, the collection of particles with a particle size of less than 0.075mm, a collection device is required to ensure the accurate collection and analysis of this part of important data. The collection device provided in this embodiment may include: 1. A collection tank. The fine particles are mainly collected through the tank. The tank should be designed to be wide enough to accommodate the fine particle suspension after all the samples are washed. The bottom of the tank should be flat and slightly inclined to facilitate the precipitation and collection of fine particles. A scale is set on the side of the tank to facilitate monitoring of the water level and the volume of the suspension. 2. A filter device. A filter device is designed at the end of the tank. Its main function is to filter and collect fine particles less than 0.075mm. It should be noted that the filter device provided in this embodiment can be a replaceable filter screen. The mesh size should be smaller than the minimum analytical sieve aperture (0.075mm) to ensure that fine particles can be effectively intercepted. 3. Sedimentation area: A sedimentation area is designed downstream of the filter device for fine particle precipitation. 4. Collection container: A movable collection container is designed at the bottom of the sedimentation area to finally collect the precipitated fine particles. 5. Water level control device: A water level control device is set in the water tank, which can be an automatic water level sensor in combination with a water valve, or a manual overflow port, to ensure the stability of the water level in the water tank and avoid the loss or mixing of fine particles due to water level fluctuations. 6. Sedimentation auxiliary equipment: Provide a static rack or static area for placing containers containing fine particle suspensions to promote the precipitation of fine particles. The static area configuration set in this embodiment is controlled by a temperature and humidity module to ensure that the precipitation process is carried out in a stable environment. 7. Operation panel and indicator: An operation panel and indicator are installed on the collection device to display information such as the water level in the water tank, the status of the filter, the position of the collection container, and to control parameters such as the water flow rate and water level. The cleaning and maintenance of the device should be taken into consideration during the design. The filter and collection container should be designed to be easy to disassemble and clean to ensure that the inside of the device is clean before each experiment to avoid the residue from the previous experiment affecting the experimental results.

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

[0052] That is, in this embodiment, after the rock test sample is disintegrated and stabilized, the samples on each level of the sieve are placed in an oven for drying, and the mass of the samples on each level of the sieve is weighed. iFor the sieve bottom mass mb0 less than 0.075 mm, the total mass of the sieve residues at each level after disintegration can be deducted from the total mass ma before disintegration. Calculated and determined, that is, the quality of the sieve bottom The particle size distribution curve after the disintegration test was drawn based on the test data.

[0053] It should be noted that the fine-grained soil particle analysis test is an important step in the test method for evaluating the disintegration resistance of fully weathered rocks. It is used to analyze the fine particle components with a particle size of less than 0.075 mm produced by disintegration, so as to more comprehensively evaluate the disintegration properties of rocks. When conducting a fine-grained soil particle analysis test, it is necessary to first select representative samples from the fine particles precipitated in the water tank collected after the disintegration test to ensure that the sample selection can reflect the fine-grained soil composition after disintegration, and then place the fine-grained soil sample in an oven for drying, with the temperature set to 105-110°C, and the duration until the sample reaches a constant weight to remove moisture from the sample. If the sample contains volatile substances, such as organic matter in carbonaceous rock, the drying temperature can be appropriately lowered, such as 65°C, to avoid changes in the sample composition. Then, the dried fine-grained soil sample is placed in a container, and an appropriate amount of dispersant, such as sodium hexametaphosphate (NaPO3) or surfactant, is added. A magnetic stirrer or ultrasonic disperser is used to fully disperse the fine particles in the sample to ensure that the fine particles in the sample can be evenly dispersed to avoid agglomeration. Then, a laser diffraction particle size analyzer is used to 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. The fine-grained soil particle size distribution curve is drawn and compared with the distribution curve before the disintegration test to intuitively show the changes in the fine-grained soil components before and after rock disintegration.

[0054] Specifically, in the process of drawing the rock particle distribution curve (before and after collapse), create a new worksheet in the software and enter the particle size distribution data before and after collapse into the table in the format of particle size and mass percentage. Then select the data area and click "Insert" → "Scatter Plot" or "Line Graph" to create a chart. Make sure that the X-axis (horizontal axis) represents the logarithmic value of the particle size and the Y-axis (vertical axis) represents the mass percentage of particles smaller than a certain particle size. Then adjust the scale of the X-axis and Y-axis to ensure that the length of 50% of the vertical axis is equal to the length of 1 order of magnitude of the horizontal axis. Add titles, legends, and data labels to make the chart clearer and easier to understand. Alternatively, you can also use professional charting software to draw the distribution curve. For example, use Origin or MATLAB software to import the data from the disintegration test into professional charting software, ensure that the data format is correct, select the appropriate chart type (scatter plot, line chart), customize the X-axis and Y-axis parameters, including logarithmic scale, axis range and axis label, use the built-in curve fitting function of the software to fit the particle distribution curve, and then use the integration tool to calculate the area under the curve.

[0055] Figure 2 is a schematic diagram of drawing a particle size distribution curve before and after disintegration according to an embodiment of the present invention, such as Figure 2 As shown, the vertical axis is the mass percentage of weathered rock particles smaller than a certain particle size, and the horizontal axis is the logarithm of the particle size. The ratio of the horizontal axis to the vertical axis is required to be: 50% of the length of the vertical axis is equal to the length of one order of magnitude of the horizontal axis. Curve a is the particle size distribution curve before disintegration, and curve b is the particle size distribution curve after disintegration.

[0056] A specific sample disintegration and weighing test method is provided below.

[0057] 1) Lay the sample in the sieve flat on the sieve, try to avoid stacking the samples, then remove the bottom sieve, stack the test sieves from top to bottom according to the sieve diameter, put the whole set of test sieves into the water tank, and then inject pure water into the water tank until the test sieves are completely submerged. Record the start time of sample immersion, accurate to minutes.

[0058] 2) After the sample is soaked in water for 12 hours, drain the water in the water tank, start from the top test sieve, rinse the sample on the test sieve with low-flow water, shake the sample sieve, and flush all particles smaller than the test sieve through the sieve to the next test sieve. When flushing the bottom sieve diameter (0.075mm), flush the fine particles through the sieve into the water tank.

[0059] 3) Weigh the overall floating density m of each level (sieve + sample) after washing. Stack the weighed analysis sieves with samples in the order of grading, immerse them in water, and repeat step 2).

[0060] 4) Rinse and weigh once every 12 hours until the floating bulk density of the sample is stable, at which time the sample is considered to have completed disintegration. The stability standard is that the difference in the floating bulk density of each level of sample is less than 0.1g after two consecutive weighings, or the difference in the floating bulk density of the sample is less than 1% after two consecutive weighings.

[0061] 5) After the disintegration is stable, put the samples on each level of sieve into the oven for drying, and weigh the mass of the samples on each level of 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, the total mass of the test before disintegration minus the total mass of the sieve residues at each level after disintegration Calculated and determined, that is, the quality of the sieve bottom The particle size distribution curve after the disintegration test was drawn based on the test data.

[0062] Step S102, calculating the integral area of ​​the curve of the weathered rock before collapse based on the rock particle distribution curve before collapse, and calculating the integral area of ​​the curve of the weathered rock after collapse based on the rock particle distribution curve after collapse.

[0063] Figure 3 is an optional weathered rock particle size integral area S before the disintegration test according to an embodiment of the present invention. A Schematic diagram, in the particle size distribution curve, calculate the particle size integral area S: the area S enclosed by the particle distribution curve a, the horizontal line A1O of the particle size mass percentage 100%, and the vertical line OA2 of 0.075 mm A ;and Figure 4 is an optional weathered rock particle size integral area S after the disintegration test according to an embodiment of the present invention. B Schematic diagram of .

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

[0065] The disintegration resistance of rock is characterized by the disintegration rate of rock (disintegration resistance index). The disintegration rate refers to the ratio of the mass difference before and after the sample disintegrates under specified conditions to the initial mass of the sample. The disintegration resistance index refers to the ratio of the rock disintegration rate to the standard disintegration rate of fully weathered or strongly weathered rock.

[0066] For example, the equivalent rock disintegration resistance index is calculated according to the following formula:

[0067]

[0068] Where I 0.075 ——Equivalent rock disintegration resistance index (%), calculated to an accuracy of 0.1.

[0069] S A ——Integral area of ​​the curve of particles larger than 0.075mm before the weathered rock collapses (mm), calculated with an accuracy of 0.01mm.

[0070] S B ——Integral area of ​​the curve of particles larger than 0.075mm after the collapse of weathered rock (mm), calculated to an accuracy of 0.01mm.

[0071] Through the above steps, the rock test sample can be placed in the test sieve, and the rock test sample can be subjected to a disintegration test through the predetermined experimental steps, and the rock particle distribution curve before disintegration and the rock particle distribution curve after disintegration are drawn, and the curve integral area of ​​the weathered rock before disintegration is calculated based on the rock particle distribution curve before disintegration, and the curve integral area of ​​the weathered rock after disintegration is calculated based on the rock particle distribution curve after disintegration, and the rock equivalent disintegration resistance index is calculated based on the curve integral area of ​​the weathered rock before disintegration and the curve integral area of ​​the weathered rock after disintegration, wherein the predetermined experimental steps at least include: water tank filling, weighing with sieve in water, and flushing with a predetermined water flow rate. In this embodiment, it can be ensured that the weathered rock sample fully absorbs water and disintegrates, and the disintegration resistance test of the loose granular weathered rock that cannot be made into a block sample is carried out, the disintegration resistance of the whole particle group of the weathered rock is measured, and the particle disintegration situation is evaluated within the whole particle size range, thereby solving the technical problem that the disintegration resistance test of strongly weathered and fully weathered rocks cannot be carried out in the related art.

[0072] Optionally, the test method for rock disintegration resistance also includes: obtaining the mass of particle size below the minimum sieve hole after disintegration and the total mass of the sample before disintegration; based on the mass of particle size below the minimum sieve hole after disintegration and the total mass of the sample before disintegration, calculating the total amount of mud of rock disintegration.

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

[0074] According to the selected analysis method, the obtained fine-grained soil particle size distribution data, including particle size, quantity and mass ratio, are sorted out. The analysis results are compared with the data before the collapse test, and the mud increment is calculated, that is, the percentage of the newly added fine-grained soil component after collapse relative to the total mass of the sample before collapse, in order to evaluate the degree of fine particles produced by rock collapse. Combined with the calculation of the total amount of mud, the overall changes of fine-grained soil particles after rock collapse are analyzed, including changes in particle size distribution, increase in fine particle content, etc. These data will help determine the rock's resistance to collapse and changes in engineering properties after collapse.

[0075] For example, the total amount of mud in rock collapse n is calculated according to the following formula: 0.075 :

[0076]

[0077] Where n 0.075 ——The total amount of mud of rock collapse (%), calculated to an accuracy of 0.1;

[0078] mb0——mass of particles less than 0.075 mm after disintegration (mass at the bottom of the sieve);

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

[0080] The mud increment n' of rock collapse is calculated according to the following formula 0.075 :

[0081]

[0082] Where n′ 0.075 ——Mudification increment of rock disintegration (%), calculated to an accuracy of 0.1;

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

[0084] ma0——mass of particles less 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 mass of particles smaller than 0.075 mm initially contained in the sample is ma0, and the mud increment is the increase on this basis.

[0087] When it is necessary to determine the equivalent disintegration resistance index, a curve is drawn; if only the mudding amount or mudding increment is measured, no curve is needed.

[0088] The test method for rock disintegration resistance provided in this embodiment can comprehensively reflect the overall disintegration of particles at all levels, as well as the state of particles after disintegration, and the equivalent disintegration resistance index n 0.075 The change of overall particle size is reflected by the integrated area ratio of particle size before and after collapse. In the actual engineering construction process, in addition to whether the rock is resistant to collapse, we are also concerned about the state of the rock after collapse. For example, the carbonaceous mudstone of a canal horse road hub collapses into silty clay, and the silty mudstone collapses into coarse sand, showing completely different engineering properties. The total amount of mudification and the increment of mudification reflect the change of fine particle content (less than 0.075mm) after collapse. The amount of fine particles determines the engineering characteristics of weathered rock, and this is used to reflect the degree of influence of collapse on the engineering properties of weathered rock.

[0089] In this embodiment, a simulation test was carried out using weathered rock samples, and the test indicators can well reflect the disintegration resistance of different weathered rocks. For example, both strongly weathered carbonaceous mudstone and fully weathered sandstone are disintegratable, but the sandstone becomes sandy after disintegration (mudification increase of 15%), and the carbonaceous mudstone becomes clay-like after disintegration (mudification increase of 60%). The engineering properties of the two are very different after disintegration.
