Description

Technical Field

[0001] The present invention relates to the field of rockfill particle measurement, and in particular to a method, device, equipment and medium for measuring the softening degree of particles. Background Art

[0002] After a rockfill dam is completed, during the initial stage of impoundment, the rockfill particles experience a rapid loss of strength upon contact with water, leading to significant particle breakage. This in turn increases dam deformation, worsens the deformation coordination between the rockfill and core, and can even trigger core hydraulic fracturing and dam collapse. Statistics show that the initial impoundment period is a high-incidence period for accidents, with substandard rockfill particle strength and softening being key factors.

[0003] Therefore, during the dam filling period, it is crucial to strengthen the testing of rockfill particle strength indicators and water softening. The conventional method uses standard cylindrical rocks of fixed size to conduct uniaxial compressive strength tests on dry and saturated samples, and then uses the ratio of these values ​​to determine the degree of softening. This method has the following shortcomings: First, the sample shape differs significantly from the rockfill particles in the field; second, the stress pattern differs significantly, with surface contact in the test and point contact in the field; third, the fixed sample size cannot reflect the influence of size effects on strength; and finally, the particle crushing and splitting patterns differ significantly from those in the field.

[0004] Currently, there is no method, device, equipment, or medium for determining the degree of softening of dry and water-saturated particles at different particle sizes that can be closer to the destruction site and ignore the influence of particle shape. Summary of the Invention

[0057] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0058] It should be noted that, in the description of the embodiments of the present invention, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0059] The terms "first," "second," and the like in this application are used to distinguish similar objects, and are not used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, the objects distinguished by "first," "second," and the like generally refer to a class of objects and do not limit the number of objects. For example, the first object may be one or more.

[0060] The present invention aims to reflect whether the particle strength of particles in an actual water-saturated state can meet actual filling requirements through the degree of softening. The degree of softening refers to the ratio of the strength of particles in a water-saturated state to the strength of particles in a dry state. Those skilled in the art understand that the strength of particles in a water-saturated state will significantly decrease. In actual application scenarios, dry particles are used for filling. However, during the water storage process, the particles will reach a water-saturated state, causing the dam body to become wet and deformed, resulting in the breakage of the rockfill body that was originally not broken. Therefore, for earth-rock dams, the present invention aims to reduce the possibility of accidents based on the softening degree measurement of particles during the initial water storage. At this time, the softening degree needs to be measured in field tests.

[0061] Figure 1 This is one of the flow diagrams of the method for determining the degree of softening of particles provided by the present invention. The present invention discloses a method for determining the degree of softening of particles, comprising:

[0062] Inputting a target particle size into a first determination function to determine a first characteristic intensity associated with the target particle size;

[0063] inputting a target particle size into a second determination function to determine a second characteristic intensity associated with the target particle size;

[0064] Determining a softening degree of particles related to a target particle size based on the first characteristic intensity and the second characteristic intensity;

[0065] The first determination function is a fitting relationship equation between the particle size and the characteristic intensity of the particles under dry conditions;

[0066] The second determination function is a fitting relationship equation between the particle size and the characteristic intensity of the particles when the particles are saturated with water.

[0067] In step 101, the first measurement function is a fitting relationship equation between the particle size and the characteristic intensity of the particles when the particles are dry, which reflects the corresponding relationship between the particle size and the characteristic intensity of the particles related to the particle size. The present invention will calculate and analyze the dry particles of each particle size and the dry particle characteristic intensity corresponding to the particle size in the embodiments described later, and then derive the fitting relationship equation. The first characteristic intensity of the particles is not the particle strength of a certain particle, but the particle strength of all particles of a certain particle size. Since the particles used in the actual particle compression experiment are irregular in shape, the breakage after compression is discrete, that is, it can be considered that they obey the Weibull distribution. The present invention aims to determine the first measurement function based on the particle strength, and then realize that for any target particle size input, the characteristic intensity of the particles reflecting the particle size can be calculated.

[0068] In step 102, the calculated second characteristic intensity associated with the target particle size is the characteristic intensity of the target particle size reflected by the target particle size after being compressed in a water-saturated state. The second measurement function reflects the fitting relationship equation between particle size and the characteristic intensity of water-saturated particles. Accordingly, the second measurement function is a fitting relationship equation derived by calculating and analyzing the characteristic intensity of water-saturated particles corresponding to each particle size. The second characteristic intensity of water-saturated particles is not the particle intensity of a specific particle, but rather the particle intensity of all water-saturated particles of a certain particle size.

[0069] In step 103, the softening degree of the particles related to the target particle size is determined based on the first characteristic intensity and the second characteristic intensity. The present invention determines the softening degree of the particles related to the target particle size using the following formula:

[0070] λ=E 0d / E 0w (1)

[0071] In formula (1), λ is the softening degree of the particles related to the target particle size, E 0d is the second characteristic intensity, E 0w is the first characteristic intensity.

[0072] Optionally, after determining the softening degree of particles related to the target particle size, the method further includes:

[0073] When the softening degree of the target particle size is less than a preset threshold, the use of particles of the target particle size is stopped.

[0074] The present invention uses irregular particles of different sizes to make the force under the simulated destruction state closer to the actual situation. Based on the Weibull distribution, the potential relationship between particle size and destruction strength is analyzed to obtain a linear measurement function, thereby determining the particle characteristic strength corresponding to particles of different particle sizes, and then determining the softening degree of particles of different particle sizes. When the softening degree of the target particle size is less than a preset threshold, the particles of the target particle size are stopped from being used. In a preferred embodiment, the preset threshold is 80%, that is, when the softening degree of the target particle size is less than 80%, the particles of the target particle size are stopped from being used.

[0075] Optionally, all particle sizes are traversed, and when the softening degree of any particle size is less than a preset threshold, particles of that particle size are stopped from being used; when the softening degree of any particle group does not meet the standard, particles of that particle group are not allowed to be used for filling earth-rock dams.

[0076] In the present invention, the particles used for earth-rock dam filling are irregular particles. For example, the large particles can reach 1 meter in size, while the small particles have a size of only 0.005 meters. The present invention is significantly different from the traditional method of measuring the degree of particle softening. In the traditional scheme, only one particle size is used to measure the degree of softening, which cannot fully reflect the particle strength of all particles of all particle sizes. According to existing research, as the particle size increases, the particle strength will decrease, making the measured degree of softening inaccurate. On the other hand, in the particle simulation test of the traditional scheme, the surface contact compression form is adopted. However, in the actual earth-rock dam particle compression process, point contact is mainly used. The destructive force required for the particles at point contact is lower than that of surface contact, which makes the results measured by the traditional method overestimate the particle strength of the particles. Due to the inappropriate simulation means of the traditional method, it cannot truly reflect the particle strength of the particles, and thus cannot accurately reflect the softening degree of the particles.

[0077] The present invention aims at the presence of particles of various sizes in earth-rock dams, and provides a technical solution that can combine different particle sizes to obtain the softening degree of particles of different sizes, thereby more comprehensively realizing the acquisition of the softening degree of all particles of all particle sizes and improving the safety factor of the earth-rock dam.

[0078] The present invention provides a method for determining the degree of particle softening. The method divides sample particles into dry particles and water-saturated particles, determines fitting relationship equations between the particle size and the characteristic intensity of the particles in the dry state, and determines fitting relationship equations between the particle size and the characteristic intensity of the particles in the water-saturated state. Thus, the first characteristic intensity can be determined by directly inputting the target particle size into a first measurement function; the second characteristic intensity can be determined by inputting the target particle size into a second measurement function. Then, based on the first characteristic intensity and the second characteristic intensity, the softening degree of particles related to the target particle size is determined. The softening degree will affect the strength index of the rockfill particles, and the possibility of accidents occurring when the particles are used for rockfill dam construction can be predicted. The present invention can quickly determine the softening degree of particles of different particle sizes, and the method is simple, easy to use, and has extremely high value.

[0079] Figure 2 This is a second flow chart of a method for measuring the degree of softening of particles provided by the present invention. According to a method for measuring the degree of softening of particles provided by the present invention, before inputting the target particle size into the first measurement function, the method includes:

[0080] Determine the particle grouping of all dry particles based on their particle size;

[0081] Crushing a first predetermined number of dry particles in each particle group to obtain a curve relationship between crushing displacement and crushing force for all dry particles in each particle group;

[0082] According to the relationship between the crushing displacement and crushing force in each particle group, the crushing energy consumption of all dry particles in each particle group is determined;

[0083] Determine the characteristic strength of dry particles in each particle group based on the crushing energy consumption of all dry particles in each particle group;

[0084] A first determination function is constructed according to the particle sizes of all particle groups and the dry particle characteristic intensity corresponding to each particle group.

[0085] In step 201, the present invention aims to determine whether the particles used in the actual dam-building process meet the use standards, and then it is necessary to select particles of different particle sizes from a large number of particles for sample testing. At this time, it is necessary to determine the particle grouping of all dry particles based on the different particle sizes. The particle grouping standard can be determined based on the maximum particle size and the minimum particle size of the sample particles selected for the particle pressure test.

[0086] In step 202, Figure 7 The relationship between the crushing displacement and the crushing force provided by the present invention is shown in FIG. Figure 7As shown, as the particles are compressed, the required force increases. At the point of failure, compression recording is stopped. Specifically, the present invention subjects each dry particle in each particle group to a particle compression test using a flat plate compression tester. During the compression process, the test ends when the force-displacement curve reaches a maximum peak and the particles undergo comminuted crushing. The relationship between the crushing displacement and crushing force curves of all dry particles in each particle group is obtained. The first preset number is preferably 30 particles. Those skilled in the art will appreciate that when the number of particles in the same particle group used for crushing is greater than 30, the experimental accuracy, as reflected by the ratio of the experimental value to the true value, can reach 98%.

[0087] In step 203, the crushing energy consumption of all dry particles in each particle group is determined based on the curve relationship between the crushing displacement and the crushing force in each particle group. Different from the traditional expression method of using the magnitude of force to reflect the crushing energy consumption, the present invention adopts the expression method of energy, that is, during the mechanical work process of the particles being compressed, a curve consisting of the extruded displacement of the particles and the force used is recorded, and the area enclosed by the curve is calculated based on the curve. Then, based on the area, the external energy required to crush the particles is reflected, and the energy is used to represent the strength of the particles.

[0088] In step 204, Figure 8 is the Weibull distribution diagram of particle crushing energy consumption provided by the present invention, such as Figure 8 As shown in FIG, it reflects the Weibull distribution diagram of the particle crushing energy consumption of the four particle groups. According to the crushing energy consumption of all dry particles in each particle group, the characteristic strength of the dry particles of each particle group is determined. Since irregular particles are used for pressure measurement in the present invention, it can be determined that the discrete irregular particles obey the Weibull distribution. According to probability statistics, the Weibull distribution is used to reflect the characteristic strength of the dry particles, which can be expressed by the following formula:

[0089]

[0090] In formula (2), P f is the probability of particle breakage, E is the particle strength; E0 is the characteristic strength of the particle, that is, the corresponding crushing energy consumption when the particle failure probability is 63%, and m is the Weibull modulus. Based on formula (2), the characteristic strength of the dry particles of each particle group can be calculated.

[0091] In step 205, Figure 9 is a graph showing the relationship between the characteristic intensity and particle size of the particles provided by the present invention, such as Figure 9As shown, a first determination function is constructed based on the particle sizes of all particle groups and the characteristic intensity of dry particles corresponding to each particle group. At this time, based on steps 201 to 204, the particle sizes of all particle groups and the characteristic intensity of dry particles corresponding to each particle group can be determined, and then all the above parameters can be linearly fitted to determine the first determination function. The first determination function can be determined by the following formula:

[0092] E0=p·d n / m (3)

[0093] In formula (3), d is the particle size, E0 is the particle characteristic intensity corresponding to the particle size, p and n are constants after linear fitting, and m is the Weibull modulus.

[0094] Figure 3 : This is a flow chart of determining the particle grouping of all dry particles provided by the present invention. According to a method for determining the degree of particle softening provided by the present invention, determining the particle grouping of all dry particles based on different particle sizes includes:

[0095] Determine the particle size range based on the maximum and minimum particle sizes among all dry particles;

[0096] determining a plurality of particle groups having different particle sizes within the particle size classification range;

[0097] Determine the upper and lower screening limits based on particle size and preset coefficients;

[0098] The dry particles with a particle size smaller than the upper screening limit and larger than the lower screening limit are classified into the particle group related to the particle size.

[0099] In step 2011, for example, the dry particles have a maximum particle size of 50 mm and a minimum particle size of 3.5 mm, and are divided into five particle groups according to different particle sizes, and the division range is 3.5 mm to 50 mm.

[0100] In step 2012, the on-site rockfill particles are measured using a vernier caliper and divided into five particle groups according to different particle sizes, with average diameters of 3.5 mm, 7.5 mm, 15 mm, 30 mm, and 50 mm, respectively.

[0101] In step 2013, the preset coefficient is a floating range that allows for screening of particle size. For example, in a particle group with a particle size of 3.5 mm, according to the preset coefficient, it is allowed to be selected within 2.8 mm to 4.2 mm. At this time, the upper screening limit is 4.2 mm, and the lower screening limit is 2.8 mm. In other embodiments, the upper screening limit and the lower screening limit can also be controlled within 15% of the average particle size.

[0102] In step 2014 , if there are particles with particle sizes of 2.1 mm, 2.3 mm, 2.7 mm, 2.9 mm, 3.3 mm, and 4.1 mm, particles with particle sizes of 2.9 mm, 3.3 mm, and 4.1 mm are preferably selected and classified into the particle group with a particle size of 3.5 mm.

[0103] Figure 4 1 is a flow chart of obtaining a curve relationship between crushing displacement and crushing force for all dry particles in each particle group provided by the present invention. The crushing process of a first preset number of dry particles in each particle group to obtain a curve relationship between crushing displacement and crushing force for all dry particles in each particle group includes:

[0104] compressing the dry particles within a preset time, and recording the corresponding relationship between the crushing displacement and the crushing force of the dry particles;

[0105] When the dry particles are broken, the compression is stopped, and a curve relationship between the breaking displacement and the breaking force of the dry particles is obtained;

[0106] Obtain the relationship between the crushing displacement and crushing force of all dry particles in each particle group.

[0107] In step 2021, the preset time is 30 seconds, 60 seconds, 90 seconds, etc., that is, the crushing process of the dry particles needs to be completed within a certain time. At this time, the corresponding relationship between the force of each mechanical work and the displacement generated is recorded.

[0108] In step 2022, if Figure 7 As shown, as the particles are squeezed and displaced by force, the particles are crushed at the destruction point. At this point, compression is stopped and a curve relationship between the crushing displacement and the crushing force of the dry particles is obtained.

[0109] In step 2023, each dry particle in the current particle group is traversed, and steps 2021 to 2022 are executed to obtain the curve relationship between the crushing displacement and the crushing force of all dry particles in the current particle group. Further, all particle groups are traversed to obtain the curve relationship between the crushing displacement and the crushing force of all dry particles in each particle group.

[0110] Figure 5 The present invention provides a flow chart for determining the crushing energy consumption of all dry particles in each particle group. The crushing energy consumption of all dry particles in each particle group is determined based on the curve relationship between the crushing displacement and the crushing force in each particle group, including:

[0111] Calculate the area formed by the curve relationship between crushing displacement and crushing force in each particle group in the coordinate mapping;

[0112] Based on the area, the crushing energy required for all dry particles in each particle group is determined.

[0113] In step 2031, the present invention differs from the traditional way of using the magnitude of force to reflect the crushing energy consumption. Instead, it uses the energy expression method. That is, in the mechanical work process of the particle being compressed, a curve formed by the extruded displacement of the particle and the force used is recorded. Based on the curve, the area enclosed is calculated. At this time, the first side is perpendicular to the horizontal axis at the point of destruction, the second side is the displacement in the horizontal axis, and the third side is the curve formed by the force used to compress the particle. Figure 7 The shaded area shown in .

[0114] In step 2032, the crushing energy consumption of all dry particles in each particle group is determined based on the area. The shaded area is the area. The area reflects the external energy required to crush the particles, and the energy is used to represent the strength of the particles.

[0115] Figure 6 This is a third flow chart of the method for determining the degree of particle softening provided by the present invention. Before inputting the target particle size into the second determination function, the method further includes:

[0116] Determine the particle grouping of all water-saturated particles based on their particle size;

[0117] crushing a second predetermined number of water-saturated particles in each particle group to obtain a curve relationship between crushing displacement and crushing force for all water-saturated particles in each particle group;

[0118] According to the relationship between the crushing displacement and crushing force in each particle group, the crushing energy consumption of all water-saturated particles in each particle group is determined;

[0119] According to the crushing energy consumption of all water-saturated particles in each particle group, the characteristic strength of water-saturated particles in each particle group is determined;

[0120] A second determination function is constructed according to the particle sizes of all particle groups and the water-saturated particle characteristic intensity corresponding to each particle group.

[0121] Step 301 may refer to step 201. At this time, the water-saturated particles used for the test are obtained by placing dry particles into a saturation cylinder and adding airless water to submerge the particles. A vacuum pump is used to saturate the cylinder to a negative pressure state until the pressure pointer in the cylinder can maintain a negative pressure for more than 24 hours. The particles are obtained, namely, water-saturated particles.

[0122] The step 302 may refer to step 202, the second preset number is preferably 30 particles, and in other embodiments, it may be 40 particles or even more, the step 303 may refer to step 203, the step 304 may refer to step 204, and the step 305 may refer to step 205. In this case, it is only necessary to replace the dry particles in steps 201 to 205 with water-saturated particles and perform the same operation to determine the characteristic intensity of the water-saturated particles of each particle group, and construct a second measurement function based on the particle sizes of all particle groups and the characteristic intensity of the water-saturated particles corresponding to each particle group.

[0123] The present invention discloses a testing process, testing method, and testing quantity for irregular particles of dry particles and water-saturated particles; describes the strength value of particles in the same particle group by particle crushing energy consumption; uses characteristic strength as a measured value for the strength of irregular rockfill particles; and calculates the softening degree of the particles using the strength characteristic values ​​of the irregular rockfill particles of dry particles and water-saturated particles. The softening degree will affect the rockfill particle strength index, and thus predict the possibility of accidents occurring when using the particles for rockfill dam construction.

[0127] The present invention provides a method for determining the degree of particle softening. The method divides sample particles into dry particles and water-saturated particles, determines fitting relationship equations between the particle size and the characteristic intensity of the particles in the dry state, and determines fitting relationship equations between the particle size and the characteristic intensity of the particles in the water-saturated state. Thus, the first characteristic intensity can be determined by directly inputting the target particle size into a first measurement function; the second characteristic intensity can be determined by inputting the target particle size into a second measurement function. Then, based on the first characteristic intensity and the second characteristic intensity, the softening degree of particles related to the target particle size is determined. The softening degree will affect the strength index of the rockfill particles, and the possibility of accidents occurring when the particles are used for rockfill dam construction can be predicted.
