[0065] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0066] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0067] The present embodiment provides a method for constructing a concrete-based crack resistance simulation model. The method can be executed by at least one of a server, a terminal, or other electronic device capable of executing the method provided by the present embodiment. In other words, the method can be executed by software or hardware installed on a terminal or server device, where the software can be a blockchain platform. The server includes, but is not limited to, a single server, a server cluster, a cloud server, or a cloud server cluster.

[0068] Reference Figure 1 FIG. 1 is a flow chart of a method for constructing a simulation model for crack resistance of concrete according to an embodiment of the present invention. In this embodiment, the method for constructing a simulation model for crack resistance of concrete includes:

[0069] S1. Receive a generation instruction for a crack resistance performance model, and start a crack resistance performance testing device according to the generation instruction, wherein the crack resistance performance testing device includes: a fixing unit, a striking unit, a penetration unit, and a model generation unit.

[0070] It should be explained that the generation instruction is an instruction for generating a crack resistance performance model.

[0071] It is understood that in the embodiments of the present invention, the concrete under test is impacted and the permeability of the concrete after the impact is tested. The crack resistance of the concrete under test is determined by the impact that the concrete can withstand and the permeability after the impact. The greater the impact that the concrete can withstand and the lower the permeability after the impact, the better the crack resistance of the concrete under test. The lower the permeability, the less likely the cracks in the concrete under test will pass through the high-pressure water flow. Therefore, the more intact the concrete is after the impact, the better the crack resistance of the concrete under test.

[0072] For example, Xiao Zhang wants to simulate the anti-cracking performance of concrete, so he issues a generation instruction, and generates a simulation model of the anti-cracking performance of concrete according to a series of operations of the generation instruction.

[0073] Importantly, the main function of the fixing unit is to fix the concrete to be tested. The main function of the impact unit is to perform the impact operation on the fixed concrete. The main function of the penetration unit is to perform penetration analysis on the impacted concrete. The main function of the model generation unit is to generate a simulation model of the concrete's crack resistance.

[0074] It needs to be explained that crack resistance refers to the ability to absorb and disperse energy in impact tests. Concrete with good crack resistance can better absorb and disperse energy when impacted, reduce the generation and expansion of cracks, and thus maintain the integrity of the structure.

[0075] For example, in roads, bridges, tunnels or protective structures, they need to withstand vehicle impacts, earthquake impacts or other dynamic loads. Therefore, it is very important to understand the crack resistance of concrete. Through impact resistance tests, the impact resistance of concrete under different impact intensities and impact conditions can be obtained. After the concrete is impacted, compared with methods such as detecting concrete surface images and surface cracks, detecting the permeability of concrete can more accurately indicate the cracking of the concrete after the impact. After accurately obtaining the crack resistance of concrete, construction engineers can choose the appropriate concrete mix ratio and construction technology to ensure the safety and durability of concrete during use.

[0076] S2. Confirm the concrete to be tested, wherein the basic parameters of the concrete to be tested include the thickness and mass of the concrete to be tested, and use a fixing unit to fix the concrete to be tested to obtain fixed concrete.

[0077] It should be explained that the concrete to be tested is the concrete waiting to be tested.

[0078] Furthermore, obtaining the shape of the concrete to be measured includes:

[0079] Starting a laser scanner, wherein the laser scanner includes a control unit and a measuring unit;

[0080] Using a control unit to perform multi-directional image acquisition on the concrete to be tested, to obtain multiple directional images;

[0081] Obtaining three-dimensional shape characteristic values ​​of the concrete to be tested based on multiple orientation images and measurement units;

[0082] The shape of the concrete to be tested is obtained based on the three-dimensional shape feature value of the concrete to be tested.

[0083] It should be understood that the acquisition of the three-dimensional shape characteristic value of the concrete to be measured based on multiple orientation images and the measurement unit includes:

[0084] Acquire a point cloud model of the concrete to be tested using multi-directional images, and splice a three-dimensional model of the concrete to be tested based on the point cloud model;

[0085] The three-dimensional model is cut using the principal plane section view projection method to obtain multiple section planes;

[0086] Projecting the multiple section planes onto the respective section planes to obtain a two-dimensional projection image of the three-dimensional model of the concrete to be tested;

[0087] Acquire the edge contour of the concrete to be measured according to the two-dimensional projection image;

[0088] The three-dimensional shape characteristic value of the concrete to be tested is calculated based on the edge contour of the concrete to be tested.

[0089] It should be explained that a laser scanner is a high-precision measuring tool that can determine the spatial position of an object's surface by emitting a laser beam and measuring the time it takes for it to reflect back. A control unit is a device used to control and manage electronic systems and their various parameters, thereby achieving the purpose of controlling system functions. The measurement unit is a measurement system using laser scanning technology that can measure information such as the size, shape, and position of an object by emitting a laser beam and receiving the reflected laser light. Multi-directional image acquisition is multi-directional image acquisition. Three-dimensional shape feature values ​​are feature values ​​derived from the precise measurement of an object's size, volume, surface area, and other characteristics.

[0090] It can be understood that the laser scanner equipment is used to perform a full-scale scan of the concrete structure at different positions and angles of the concrete to be tested to ensure that the shape information of the concrete to be tested is captured, the shape information of the concrete to be tested collected by the measuring unit is analyzed, and the concrete three-dimensional model is reconstructed using SW software. These images and measuring units contain point cloud data of the concrete surface. Each point in the point cloud data has its precise coordinates in three-dimensional space. According to the three-dimensional shape feature values ​​of the concrete to be tested, the precise three-dimensional shape of the concrete to be tested can be constructed.

[0091] For example, a team of bridge engineers decides to build a new bridge. Before construction, they conduct a detailed inspection of the concrete sample structure used in the bridge to assess its structural integrity and required maintenance. The bridge engineer uses a laser scanner to scan the concrete sample, activates the equipment, and performs necessary calibration to ensure measurement accuracy. Using a control unit, the bridge engineer scans the concrete sample. The laser scanner emits a laser at each location and captures the reflected laser points, forming a multi-directional image. The collected images and measurement data are transmitted to a computer. Using SW software, the bridge engineer integrates this data to generate a three-dimensional model of the bridge concrete structure. The SW software analyzes the point cloud data and extracts the three-dimensional shape characteristics of the concrete sample, such as the width and length of the crack, surface unevenness, and structural deformation. Based on these characteristics, a simulation model of the crack resistance performance is generated.

[0092] Furthermore, the obtaining of the shape of the concrete to be tested based on the three-dimensional shape feature value of the concrete to be tested includes:

[0093] Wherein, the three-dimensional shape characteristic values ​​include the surface area, volume and area of ​​the concrete to be tested;

[0094] Reconstructing a three-dimensional model diagram using the surface area, volume, and area of ​​the concrete to be tested to obtain a reconstructed model diagram;

[0095] The reconstructed model image is verified and calibrated to obtain the shape of the concrete to be tested.

[0096] It should be explained that the reconstructed three-dimensional model diagram is a model diagram that converts a two-dimensional image, data or other forms of information into a three-dimensional visualization.

[0097] Furthermore, the fixing unit includes a clamp and a rubber base, and the clamp can be dynamically adjusted according to the shape of the concrete to be tested. The rubber base is located at the bottom of the clamp, and a hole is provided in the middle of the rubber base, and the hole is provided for the water inlet pipe to be inserted. The fixing unit is used to fix the concrete to be tested to obtain fixed concrete, including:

[0098] Obtaining the shape of the concrete to be tested, wherein the shape of the concrete to be tested includes a sphere, a cylinder, or a cube;

[0099] Confirm the size of the concrete according to the shape of the concrete to be tested;

[0100] The concrete to be tested is fixed with a clamp using the size of the concrete to obtain fixed concrete.

[0101] It should be noted that concrete dimensions refer to the concrete's thickness, length, and width. A fixture is a device that secures the concrete to be tested. A rubber base is a device used to support the concrete to be tested, primarily consisting of a base and a rubber pad. Fixed concrete is the concrete that is secured by the concrete fixture being tested.

[0102] For example, an engineer takes a cube of concrete to be tested, confirms the size of the concrete to be tested, and uses a clamp to fix the cube of concrete to be tested based on the length, width, and height of the cube. The bottom of the cube of concrete to be tested is attached to a rubber base to stabilize the cube of concrete, thereby obtaining fixed concrete.

[0103] S3. Determine the striking position and striking force of the striking unit for striking the fixed concrete, and strike the fixed concrete based on the striking position and striking force to obtain struck concrete.

[0104] It is understood that the "struck concrete" refers to concrete that has been struck according to the striking position and striking force. The striking position is the position where the concrete is to be struck. The striking force is the force with which the concrete is struck.

[0105] Furthermore, the step of striking the fixed concrete based on the striking position and striking force to obtain struck concrete includes:

[0106] Wherein, the striking unit includes: an impactor and an impact sensor, and the impactor is fixed above the impact sensor;

[0107] Impact data is obtained based on the striking position and striking force, the fixed concrete is struck using the impact data and the impactor, and feedback data is obtained using the impact sensor, wherein the feedback data includes the feedback position and the feedback force. After confirming that the fixed concrete has been struck based on the feedback position and the feedback force, the struck concrete is obtained.

[0108] It should be noted that impact data refers to the position and force data of the set striking position and striking force. The impact sensor is a sensor that records and outputs striking position and striking force data. Feedback data refers to the position and force data of the striking position and striking force after the strike, primarily recording the position and force data of the set striking position and striking force.

[0109] For example, the striking position is set to A, the striking force is X, and a striking operation is performed on the concrete to be tested to obtain impact data, where the impact data is the striking position set to A and the striking force is X.

[0110] For example, an engineer needs to test the crack resistance of a concrete sample and determine the required striking position and striking force. If the center point of the fixed concrete needs to be struck, the position of the center point is calculated based on the measured dimensions, and the required striking force is set. After the striking unit executes the operation, the impact sensor records and outputs the striking position and striking force data information. If the fixed concrete does not crack when struck by the impactor, it means that its crack resistance is good.

[0111] S4. Start the infiltration unit, wherein the infiltration unit includes a water inlet pipe and a water outlet pipe, calculate the water inlet speed of the water inlet pipe according to the striking force, and use the water inlet pipe to perform water injection operation on the side of the concrete that has been struck, wherein the water injection speed is the water inlet speed.

[0112] It should be understood that the permeability unit can provide experimental data on crack morphology, size and distribution. These experimental data are very important for establishing a simulation model of crack resistance. The results obtained through actual permeability testing can be used to calibrate and adjust the parameters in the simulation model to ensure that the model can accurately simulate the crack resistance of concrete.

[0113] Furthermore, the water inlet speed of the water inlet pipe is calculated according to the striking force, including:

[0114] The water inlet pressure of the infiltration unit to the water inlet pipe is calculated based on the striking force;

[0115] The water inlet speed of the water inlet pipe is calculated according to the water inlet pressure, wherein the calculation formula of the water inlet speed is:

[0116]

[0117] Where Q represents the water inlet velocity, ΔP represents the water inlet pressure of the inlet pipe, R represents the radius of the inlet pipe, μ represents the dynamic viscosity of the fluid, and L represents the length of the inlet pipe;

[0118] The method of calculating the water inlet pressure of the infiltration unit applied to the water inlet pipe according to the striking force includes:

[0119] The water inlet pressure is calculated according to the following formula:

[0120]

[0121] Among them, P i represents the water inlet pressure of the i-th water inlet pipe in the permeation unit, P max Indicates the maximum water inlet pressure of the i-th water inlet pipe, N j It represents the impact force of the impact unit hitting the fixed concrete for the jth time.

[0122] It's important to explain that the water inflow velocity is the speed at which water enters the concrete. The dynamic viscosity of a fluid is a physical quantity that represents the internal resistance of the fluid. It indicates the degree of friction between adjacent layers of the fluid as it flows. The greater the viscosity, the greater the internal friction and the worse the fluid's flowability.

[0123] It should be explained that the maximum water inlet pressure is the maximum water pressure value allowed to be applied to the concrete structure in the concrete penetration test. The maximum water pressure value is determined based on the strength requirements of the concrete structure to ensure that the integrity and safety of the concrete structure are not damaged under the action of water pressure.

[0124] S5. Using the water outlet pipe, perform water outlet operation on the other side of the concrete that has been struck, and detect the water outlet speed.

[0125] Furthermore, the method of performing a water discharge operation on the other side of the concrete having been struck by using the water discharge pipe and detecting the water discharge speed includes:

[0126] The water outlet speed is calculated according to the following formula:

[0127]

[0128] Among them, h f Indicates the water outlet speed, P i represents the water inlet pressure of the i-th water inlet pipe in the permeation unit, L a represents the length of the outlet pipe, g represents the acceleration due to gravity, and D represents the diameter of the outlet pipe.

[0129] It should be explained that the water outflow velocity is the velocity at which the fluid flows out from the interior of the concrete.

[0130] For example, an engineer needs to evaluate the internal structure of a concrete. The evaluation content is the permeability of the internal structure of the concrete. The engineer uses a striking unit to strike the concrete structure multiple times and records the force N of each strike. j , each time it hits, the water inlet pressure P is calculated based on the hitting force and the water inlet speed of the water inlet pipe i , based on the data analysis of water inflow velocity and water inflow pressure, the permeability of the concrete structure during this impact is evaluated.

[0131] S6. Import the basic parameters of the concrete to be tested, the striking position, the striking force, and the water outlet speed into the model generation unit to obtain a crack resistance performance model.

[0132] Furthermore, the basic parameters of the concrete to be tested, the striking position, the striking force, and the water outlet speed are introduced into the model generation unit to obtain the crack resistance performance model, including:

[0133] constructing a three-dimensional model of the concrete to be tested based on the basic parameters, and retrieving a model striking position corresponding to the striking position in the three-dimensional model;

[0134] The striking force and water outlet speed corresponding to the striking position are introduced into the striking position of the model to obtain the anti-cracking performance model.

[0135] It should be noted that the model impact position is retrieved from the three-dimensional model. Optionally, the distance between the impact position and the concrete to be tested is measured on multiple preset reference surfaces in the concrete to be tested, thereby obtaining the coordinates of the impact position. The model impact position is then retrieved from the three-dimensional model using these coordinates. For example, if the concrete to be tested is a cube, multiple surfaces of the cube at different locations can be used as reference surfaces. Optionally, SW is used as the three-dimensional modeling software for the concrete to be tested, and the three-dimensional model is constructed using this software and basic parameters. The technology for constructing a three-dimensional model using basic parameters is conventional. Importing the impact force and water discharge velocity relative to the model impact position into the model impact position allows the corresponding impact force and water discharge velocity to be read in the three-dimensional model according to different model impact positions, thereby facilitating a more intuitive construction of a concrete crack resistance model. Optionally, the method for importing the impact force and water discharge velocity is to mark the model impact position, and the method for marking the corresponding values ​​of the impact force and water discharge velocity is conventional. Other techniques can achieve the same effect.

[0136] It is understandable that the crack resistance performance is optimized according to the simulation results, and then the optimized concrete crack resistance performance is introduced into the model generation unit, thereby obtaining the crack resistance performance model.

[0137] It should be explained that the model generation unit is a unit that optimizes and generates data information received by simulation.

[0138] The present invention aims to solve the problems described in the background art. The present invention receives a generation instruction for a crack resistance model and activates a crack resistance test device according to the generation instruction. The crack resistance test device includes a fixing unit, a striking unit, a penetration unit, and a model generation unit. The crack resistance test device simulates the crack resistance under impact conditions that may be encountered in actual use. The present invention confirms the concrete to be tested, wherein the basic parameters of the concrete to be tested include the thickness and mass of the concrete to be tested, fixes the concrete to be tested using a fixing unit to obtain fixed concrete, determines the striking position of the striking unit to strike the fixed concrete, and the striking force of the striking fixed concrete. Based on the striking position and striking force, the fixed concrete is struck to obtain struck concrete. Through a systematic testing process, the present invention aims to evaluate the crack resistance of the concrete to be tested when subjected to impact through testing. The present invention starts a permeation unit, wherein the permeation unit includes a water inlet pipe and a water outlet pipe, calculates the water inlet speed of the water inlet pipe according to the striking force, uses the water inlet pipe to perform a water injection operation on the side of the concrete that has been struck, wherein the water injection speed is the water inlet speed, and at the same time, uses the water outlet pipe to perform a water outlet operation on the other side of the concrete that has been struck, and detects the water outlet speed, tests the permeability of the concrete through the permeation operation, and shows the crack resistance of the concrete to be tested based on the permeability.
