[0002] The biomimetic simulation of landslide masses is one of the primary factors influencing landslide surge characteristics. Accurately and realistically simulating the landslide mass morphology and the interactions between the rock and soil within it is a prerequisite for landslide surge testing. Currently, most researchers use independent blocks, multiple blocks, or granular materials to simulate landslide masses, which are simple and easy to implement. However, these methods only consider the friction between the rock and soil within the landslide and the friction between the rock and soil and the sliding surface. This makes it difficult to simulate the cohesive effects between particles within the sliding mass, making it difficult to reflect the actual behavior of the landslide mass during sliding deformation, potentially leading to inaccurate test results.

DETAILED DESCRIPTION

[0020] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0021] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The main solution of the embodiment of the present application is to provide a landslide simulation device, including: an air pump, a vacuum film, a simulated sliding body, an electromagnet, a sliding surface, a magnet block, and a control system, wherein the simulated sliding body is made of a non-Newtonian fluid material, and the sliding surface is in a specific groove shape; the vacuum film covers the surface of the simulated sliding body and is linked with the air pump to vacuum the simulated sliding body; the magnet block is embedded in the simulated sliding body, and the electromagnets are distributed at different elevations below the sliding surface. The electromagnets are used to apply force to the magnet block placed in the simulated sliding body to adjust the sliding speed and direction of the simulated sliding body; the control system is used to control the air pump and the electromagnet. This solves the problem of difficulty in simulating the cohesion effect between particles inside the sliding body during the sliding body simulation process.

[0023] Most existing researchers use independent blocks, multiple blocks, or granular materials to simulate landslides, which is simple and easy to implement. However, these methods only consider the friction between the rock and soil within the landslide and the friction between the rock and soil and the sliding surface. This makes it difficult to simulate the cohesion between particles within the landslide, making it difficult to reflect the actual situation of the landslide during sliding deformation, which may lead to inaccurate test results.

[0024] The present application provides a landslide simulation method that takes into account the cohesive force inside the sliding body, which solves the problem that it is difficult to simulate the cohesive effect between particles inside the sliding body during the sliding body simulation process.

[0025] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution capabilities, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of performing the above functions, such as a landslide simulation device. This embodiment and the following embodiments will be described below using a landslide simulation device as an example.

[0026] Based on this, the embodiment of the present application provides a landslide simulation device, referring to Figure 1 , Figure 1 This is a structural diagram of the first embodiment of the landslide simulation device of this application.

[0027] The landslide simulation device includes: an air pump (not shown in the figure), a vacuum film 2, a simulated sliding body 3, an electromagnet 4, a sliding surface 5, a magnet block 6, and a control system 7. The simulated sliding body 3 is made of a non-Newtonian fluid material, and the sliding surface 5 has a specific groove shape. The vacuum film 2 covers the surface of the simulated sliding body 3 and is linked with the air pump to perform vacuum treatment on the simulated sliding body 3; The magnet block 6 is embedded in the simulated slide 3, and the electromagnets 4 are distributed at different heights below the sliding surface 5. The electromagnets 4 are used to apply force to the magnet block 6 placed in the simulated slide 3 to adjust the sliding speed and direction of the simulated slide 3; The control system 7 is used to control the air pump and the electromagnet 4 .

[0028] It should be noted that the use of a non-Newtonian fluid material to simulate the simulated slider 3 not only ensures that it maintains a certain shape under pressure, but also exhibits "fluidization" characteristics similar to those of an actual slider under its own weight. Non-Newtonian fluids are insoluble in water, ensuring a clear interface between the slider and the water during the test, which contributes to the accuracy of the test results. The cohesive effect of the non-Newtonian fluid not only simulates the friction effect of particles within the slider, but also simulates the cohesive effect within the slider.

[0029] The simulated slide 3 is placed on a specific groove sliding surface 5, and the magnet block 6 is pre-placed in the simulated slide 3. It can not only act as a large block in the sliding of the slide, but also control the sliding speed of the simulated slide 3 under the action of the strong and weak electromagnetic forces of the electromagnets 4 pre-buried at different heights.

[0030] In practice, the simulated slider 3 is pre-covered with a vacuum film 2 and sealed on all sides to maintain its stability. Before adding water, the simulated slider 3 is vacuumed and drained using an air pump. This ensures that the simulated slider 3 has a certain strength under atmospheric pressure, maintaining a stable shape and preventing slippage. Water 8 is then added to cover the bottom of the slider.

[0031] like Figure 2 As shown, Figure 2This is a schematic diagram of the arrangement of the vacuum film 2. The vacuum film 2 covers the surface of the simulated sliding body 3 and seals the surrounding area. When vacuuming is required before adding water 8, the surrounding area is vacuumed using the air pump 1. This ensures that the simulated sliding body 3 has a certain strength under the action of atmospheric pressure, maintaining a stable shape and preventing sliding. Water 8 is then added to cover the bottom of the sliding body.

[0032] It should be noted that the electromagnet 4 can be located at different heights of the sliding surface 5. When the electromagnet 4 is turned on, the vacuum is released, so that the simulated sliding body 3 is controlled to slide down through the control system 7.

[0033] At the same time, when it is necessary to evacuate the air or to control the current of the simulated slide 3 , the air pump 1 , the electromagnet 4 or the simulated slide 3 can be controlled by the control system 7 .

[0034] In this embodiment, the landslide simulation device includes: an air pump, a vacuum film 2, a simulated sliding body 3, an electromagnet 4, a sliding surface 5, a magnet block 6 and a control system 7, wherein the simulated sliding body 3 is made of a non-Newtonian fluid material, and the sliding surface 5 is a specific groove shape; the vacuum film 2 covers the surface of the simulated sliding body 3, and is linked with the air pump 1 to vacuum the simulated sliding body 3; the magnet block 6 is embedded in the simulated sliding body 3, and the electromagnet 4 is distributed at different elevations below the sliding surface 5. The electromagnet 4 is used to apply force to the magnet block 6 placed in the simulated sliding body 3 to adjust the sliding speed and direction of the simulated sliding body 3; the control system 7 is used to control the air pump and the electromagnet 4. First, a non-Newtonian fluid material is used to simulate the sliding body 3. This can not only ensure that it maintains a certain shape under pressure, but also exhibit "fluidization" characteristics similar to the sliding of an actual sliding body under its own weight. Non-Newtonian fluid is insoluble in water, which ensures a clear interface between the sliding body and the water body during the test, which is beneficial to the accuracy of the test results. The cohesion effect of the non-Newtonian fluid itself can not only simulate the friction effect of the particles inside the sliding body, but also simulate the cohesion effect inside the sliding body, thereby truly reflecting the cohesion effect between the particles inside the sliding body, ensuring that the sliding body in the physical test has basically consistent characteristics with the field, and improving the accuracy and reliability of subsequent test results.

[0035] Based on the first embodiment of the landslide simulation device of the present application, the present application also provides a landslide simulation method, please refer to Figure 3 , Figure 3 This is a flow chart of the first embodiment of the landslide simulation method of the present application.

[0036] In this embodiment, the landslide simulation method is applied to the control system of the landslide simulation device described above. The landslide simulation device includes: an air pump, a vacuum film, a simulated sliding body, an electromagnet, a sliding surface, a magnet block and a control system.

[0037] The method includes steps S10 to S40: Step S10: placing the simulated sliding body on the sliding surface.

[0038] It should be noted that the simulated sliding body is modeled using a non-Newtonian fluid material. Non-Newtonian fluids are insoluble in water, ensuring a clear interface between the sliding body and the water during the test. This non-Newtonian fluid material maintains a certain shape under pressure and exhibits "fluidization" characteristics similar to those of an actual sliding body under its own weight. Prior to conducting landslide simulations, the simulated sliding body can be placed on the sliding surface.

[0039] The sliding surface is a specific grooved sliding surface, usually with a certain inclination angle or different elevations, simulating the ground in a geological or natural environment, which may be an inclined earth slope, rock slope or artificial surface.

[0040] By placing the simulated sliding body on a preset sliding surface (such as a simulated slope or inclined ground), preparation for subsequent simulation is made. This ensures that the simulated sliding body can slide on the sliding surface and perform a realistic simulation.

[0041] In a feasible implementation manner, a magnet block is further placed in the simulated sliding body. Therefore, before step S10, steps S01 to S03 are further included: Step S01: Obtain the shape and magnetic field strength of the magnet block; It is understandable that the magnet block will generate a magnetic field force that affects the motion state of the slider. If the slider is a metal or an object with magnetic material, the force exerted by the magnet on it will depend on the strength and direction of the magnetic field and the magnetism of the slider. The magnetic force of the magnet block can indirectly adjust the sliding speed by changing the friction between the slider and the surface. A strong magnetic field can reduce friction and accelerate the sliding; conversely, a weak magnetic field may increase friction and slow down the sliding speed. Therefore, the properties of the magnet block can be defined first, including shape and strength. The shapes of the magnet block include rectangular parallelepiped, cylinder, cube, etc., and the strength of the magnet block includes the magnetic field strength or magnetic parameters of the magnet block.

[0042] Step S02: determining the relative position of the magnet block based on the shape and the magnetic field strength; In a specific implementation, the relative position of the magnet block can be set according to the shape of the magnet block and the magnetic field strength, for example, the specific position and direction of the magnet block in the simulated sliding body.

[0043] Step S03: placing the plurality of magnet blocks in the simulated slide according to the relative positions.

[0044] It can be understood that multiple magnet blocks can be placed in the simulated slide according to their relative positions. By placing the magnet blocks in the simulated slide in advance, they can not only act as large and medium-sized blocks in the sliding of the slide, but also control the sliding speed of the slide under the action of the strong and weak electromagnetic forces of the pre-buried electromagnets at different elevations.

[0045] In a specific implementation, the position and distribution of the magnet blocks may be adjusted according to the subsequent sliding conditions of the simulated sliding body, so that the simulated sliding body can achieve an optimal sliding speed.

[0046] Step S20: pre-covering the surface of the simulated sliding body with the vacuum film, and sealing the four sides of the covered simulated sliding body.

[0047] It should be noted that vacuum film is a thin-film material that can be tightly applied to a surface by vacuuming it. It can be used to reduce surface friction or simulate specific physical conditions (such as reduced air pressure). In this simulation environment, it might be used to simulate friction reduction or the physical properties of a real landslide.

[0048] The edge of the film can be sealed to ensure airtightness, maintain an internal vacuum state, and ensure effective physical contact between the film and the simulated sliding body, thereby achieving a sealing effect.

[0049] The vacuum film will be covered on the surface of the simulated sliding body to reduce the friction between the sliding body and the sliding surface. The operation of sealing all around is to ensure that the vacuum state is maintained in order to simulate low friction or specific landslide conditions.

[0050] Step S30: arranging the corresponding electromagnets at different elevations of the sliding surface.

[0051] It's important to note that an electromagnet is a device that generates a magnetic field through an electric current, producing a controllable magnetic force. In simulations, electromagnets can be used to simulate external forces at different elevations or slopes, or to control the motion of a sliding object.

[0052] Different elevations refer to the different heights or inclinations of the sliding surface. These varying elevations may affect the sliding trajectory or sliding dynamics of the simulated slide. Electromagnets are typically placed at different elevations on the sliding surface to control the movement of the simulated slide through the magnetic field they generate, simulating the external forces acting during a landslide. The electromagnets may attract or repel the slide, thereby affecting its sliding behavior and simulating dynamic changes on different slopes.

[0053] Imagine installing electromagnets at the top, middle, and bottom of a ramp. By adjusting the strength of the electromagnets, the simulation can simulate the physical and mechanical environment at different locations along the ramp. For example, the electromagnet at the top might simulate the effect of gravity, initiating the movement of a slider, while the electromagnet at the bottom might simulate the acceleration of the slider caused by the change in slope.

[0054] In a feasible implementation, step S30 may include steps S31 to S34: Step S31: obtaining the sliding surface size of the sliding surface.

[0055] Slide surface dimensions refer to the actual physical size and shape of the slide surface, including spatial characteristics such as length, width, and height. Slide surface dimensions are fundamental to the design and layout of the experimental system, determining the layout of the slide surface and the spatial configuration of other related equipment.

[0056] Assuming the sliding surface is a simulated soil slope, measurement tools (such as laser rangefinders and calipers) can be used to measure the slope's length, width, and height difference to determine the specific dimensions of the sliding surface. This data will provide a basis for subsequent sliding surface segmentation and electromagnet placement.

[0057] Step S32: Divide the sliding surface according to the sliding surface size to obtain a sliding surface grid.

[0058] A sliding surface mesh is a grid structure that divides a sliding surface into smaller blocks based on their size. The mesh can be adjusted to suit different needs, such as size and number, and is often useful for analyzing and simulating the motion of objects on a sliding surface.

[0059] If the sliding surface is a rectangular area, assuming it is 10 meters long and 5 meters wide, depending on the experimental requirements, the sliding surface may be divided into small blocks of 1 meter by 1 meter, resulting in a 10×5 grid, with each grid cell representing a small area of the sliding surface. This allows for precise control of the experimental setup for each area.

[0060] Step S33: determining the arrangement points of each electromagnet according to the sliding surface grid.

[0061] Layout points are the specific locations of the electromagnets on the sliding surface. These points are planned according to the sliding surface grid, which determines the layout and placement of the electromagnets to ensure that each area receives the appropriate magnetic influence.

[0062] Based on the sliding surface grid obtained in step S32, the specific positions of the electromagnets within each grid cell are determined. These positions determine the actual placement of the electromagnets during the experiment, ensuring that the electromagnets can influence the trajectory of the sliding body or simulate landslides. For example, an electromagnet may be placed at the center of each grid cell, or specific grid cells may require a stronger magnetic force (e.g., near the slope). This method allows for precise positioning of each electromagnet.

[0063] Assume that the sliding surface size is , the sliding surface can be divided into a Each grid can be represented as , the layout point of each electromagnet can be represented by a grid:

[0064] i and j are the indices of the grid rows and columns respectively.

[0065] Step S34: arranging the electromagnets in parallel based on the arrangement points.

[0066] After determining the placement points, the electromagnets can be arranged in parallel using these placement points. The purpose of this arrangement is to ensure that each electromagnet can be controlled individually as needed, and that their actions do not interfere with each other. This approach is often used to ensure that multiple electromagnets can act independently or in a coordinated manner on the slider, affecting its motion behavior.

[0067] The accuracy of landslide simulation experiments is ensured through precise sliding surface measurement, meshing, electromagnet positioning, and parallel arrangement. This provides more refined control and layout for simulations, ensuring that the effects of various factors are fully reflected during the simulation process, thereby helping to understand the physical mechanisms of landslides.

[0068] Step S40: controlling the air pump, the electromagnet, and the simulated sliding body to complete landslide simulation.

[0069] In practice, the entire landslide simulation process can be completed by adjusting the air pump, magnetic field, and the state of the sliding body. This may include controlling the air pump to create a vacuum, adjusting the electromagnet to influence the movement of the sliding body, and ultimately achieving the dynamic process of the landslide. This also includes controlling the movement of the simulated sliding body, providing valuable data and evidence for actual landslide prediction, risk assessment, and emergency response.

[0070] This embodiment places the simulated sliding body on the sliding surface; pre-covers the surface of the simulated sliding body with a vacuum film and seals the surface of the simulated sliding body; distributes corresponding electromagnets at different elevations on the sliding surface; and controls the air pump, electromagnets, and simulated sliding body to complete a landslide simulation. By placing the simulated sliding body on the sliding surface and sealing it with the vacuum film, the interaction between the sliding body and the sliding surface can be simulated. The vacuum film provides precise control of the friction force on the sliding body's surface, allowing for more precise control of the sliding body's movement and landslide process. This enables a more realistic reproduction of the physical phenomena of actual landslide events, improving the authenticity and reliability of the simulation results. Placing electromagnets at different elevations on the sliding surface allows for different magnetic forces to be applied at different locations, adjusting the sliding body's movement at different elevations, as needed for landslide simulation. This distributed electromagnet layout makes the simulation process more flexible and controllable, and can simulate the effects of different terrain on the sliding body's movement, thereby reflecting the effects of slope and topographic changes on sliding body behavior in real landslides.

[0071] Based on the first embodiment of the landslide simulation method of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction and will not be repeated hereafter. Figure 4 , step S40 includes steps S401 to S404: Step S401: Before adding water, control the air pump to vacuum the interior of the simulated sliding body and drain the water.

[0072] It should be noted that before adding water, the interior of the sliding body can be evacuated and drained by an air pump, so that the sliding body has a certain strength under the action of atmospheric pressure, thereby maintaining a stable shape without sliding.

[0073] Step S402: Control the electromagnet to turn on and release the vacuum.

[0074] In practice, when a simulation is needed, the electromagnets can be controlled to turn on. Specifically, currents of varying intensities can be applied to the electromagnets to activate them. Simultaneously, the vacuum is released, and the control system controls the simulated slide under the influence of varying currents. Electromagnets at different elevations are connected in parallel, so they do not affect each other.

[0075] Step S403: After the vacuuming is completed, water is added to the simulated sliding body until the water covers the bottom of the simulated sliding body.

[0076] In a specific implementation, after the vacuum is released, water can be added to the sliding surface where the simulated sliding body is located until the water covers the bottom of the simulated sliding body, so as to facilitate simulation.

[0077] Step S404: controlling the simulated sliding body to slide to complete the landslide simulation.

[0078] It should be noted that after the water body is added, the simulated sliding body can be controlled to slide, and the sliding speed or direction of the simulated sliding body can be controlled during the sliding process to complete the landslide simulation.

[0079] In a feasible implementation, step S404 may include steps A11 to A14: Step A11: controlling the simulated slider to slide using an initial current control signal, and obtaining a current position of the simulated slider; It should be noted that the initial current signal is the initial value input when the slider starts to move, and is usually used to start the device. When the simulated slider slides, the current position of the simulated slider can be obtained in real time.

[0080] Controlling the movement of the simulated slider begins by inputting an initial current signal to a motorized device or electromagnet. This initial current signal provides the driving force that initiates the slider's movement. Simultaneously, the system acquires the slider's current position in real time for subsequent control and adjustment.

[0081] Step A12: Calculating a position error based on the target position and the current position; The target position is the desired position of the slider, typically a value set by the system or entered by the user. Position error is the difference between the target position and the current position, typically expressed as the target position minus the current position. It measures the deviation of the slider from the desired target position.

[0082] Position error: refers to the difference between the target position and the current position, usually expressed as the target position minus the current position. It is an indicator of the deviation between the slider and the desired target position.

[0083] Step A13: Calculating and adjusting the current control signal according to the position error; Based on the position error, the system calculates and outputs a new current control signal to bring the simulated slider closer to the target position. Generally, the larger the position error, the larger the current control signal adjustment required, and vice versa.

[0084] Based on the calculated error, the system adjusts the current control signal. Generally, if the position error is large, meaning the slider is far from the target position, the system may need to increase the current output to accelerate the slider. If the error is small, the current output may need to be reduced to slow the slider and prevent it from overshooting the target position. For example, if the position error is 10 meters, the system may calculate an adjusted current signal based on a pre-set control algorithm (such as proportional control). For example, the system might adjust the current from 5A to 6A based on the error size to accelerate the simulated slider movement and reduce the error.

[0085] Step A14: adjusting the initial current control signal according to the adjusted current control signal, so as to control the sliding of the simulated slider by means of the adjusted current control signal.

[0086] The calculation is as follows:

[0087] e(t) is the error between the current position and the target position, K p , K i , K d are the proportional, integral and differential gains, and u(t) is the adjustment current control signal, which directly affects the electromagnetic force.

[0088] The adjusted current signal calculated above is applied to actual control. By adjusting the initial current signal, the system allows the slider to continuously approach the target position and ultimately reach the set position. This may involve real-time adjustment of the current magnitude to control the slider's speed and position. If the system calculates that the adjusted current signal should be 6A, then at this stage, the system will adjust the initial current control signal from 5A to 6A, thereby increasing the driving force, accelerating the vehicle and helping it approach the target position (20 meters) more quickly.

[0089] Feedback control (e.g., PID control) is used to precisely control the motion of the simulated slider to ensure it reaches the target position. By continuously calculating the error between the current position and the target position and adjusting the current control signal based on this error, the simulated slider can be precisely controlled during dynamic processes.

[0090] In a feasible implementation, step S404 may include steps B11 to B15: Step B11: Obtain the current speed and target speed of the simulated slider.

[0091] Define the current velocity error of the slider e(t)=V target -V currentThe error rate of change Δe(t) = de / dt is used as input variables. Therefore, the current speed and target speed of the simulated slider can be obtained first.

[0092] Step B12: Calculate the speed error and the error change rate according to the current speed and the target speed.

[0093] In a specific implementation, the speed error e(t) and the error change rate Δe(t) may be calculated according to the current speed and the target speed.

[0094] Step B13: Obtain a fuzzy rule set.

[0095] It should be noted that different fuzzy rule language values can be defined in advance, such as negative large, negative small, zero, positive small, positive large, etc., and fuzzy rules can be defined. For example, if the error is "positive large" and the error change rate is "zero", the water flow rate should be increased. If the error is "negative small" and the error change rate is "positive small", the water flow rate should be decreased.

[0096] Step B14: matching a target fuzzy rule in the fuzzy rule set according to the speed error and the error change rate.

[0097] In a specific implementation, the most appropriate target fuzzy rule can be matched in the fuzzy rule set according to the speed error and the error change rate. For example, if the speed error is positive and the error change rate is zero, the target fuzzy rule is to increase the water speed.

[0098] Step B15: Control the water body where the simulated sliding body is located according to the target fuzzy rule.

[0099] It is understandable that the water body where the simulated sliding body is located can be controlled by the target fuzzy rule. In a feasible implementation, step B15 may include: obtaining a control instruction based on the target fuzzy rule; and when the control instruction is to adjust the flow of the water body, adjusting the flow of water added to the simulated sliding body.

[0100] It should be noted that the control instruction can be obtained according to the target fuzzy rule. For example, if the target fuzzy rule is to increase the water flow velocity, the control instruction is to increase the water flow velocity. The flow velocity of the water in which the simulated sliding body is located is increased through the control instruction. If the control instruction is to adjust the flow rate of the water body, the water flow rate can be adjusted, thereby making timely adjustments to the changing environment.

[0101] Before adding water, this embodiment controls the air pump to evacuate and drain the interior of the simulated sliding body; controls the electromagnet to activate and release the vacuum; after the vacuum is complete, water is added to the simulated sliding body until it covers the bottom of the simulated sliding body; and controls the simulated sliding body to slide, completing the landslide simulation. Through precise control and operation of the simulation process, not only can the realism of the landslide simulation be enhanced, but also the efficiency and accuracy of research can be improved, providing an important tool and method for landslide prediction, prevention, and research.
