Description

Technical Field

[0001] The present application relates to the technical field of geological structure simulation, and in particular to a physical simulation device and method for quantitatively controlling the angle of strike-slip motion. Background Art

[0002] Structural physical simulation is an experimental technique that can reproduce the formation process of geological structural deformation under laboratory conditions, and quantitatively analyze the deformation results and the causal mechanism of geological structures through digital recording, image playback and image processing. At present, structural physical simulation is an important method for studying the formation and evolution of strike-slip faults. It uses different materials and experimental models to reproduce the process of structural deformation and reveal the geometric, kinematic, dynamic characteristics and evolution process of strike-slip faults.

[0003] There are three types of strike-slip movement, namely discrete torsion (tension-torsion strike-slip movement), convergent torsion (compression-torsion strike-slip movement) and parallel torsion (pure torsion strike-slip movement). Compression-torsion / tension-torsion is a combination of strike-slip or simple shear movement along the structural strike direction and contraction (or extension) perpendicular to the structural strike direction. The actual geological structural stress situation is complex and changeable. There are few pure torsion strike-slip movements, and most of them are tension-torsion or compression-torsion strike-slip compound movements. There are generally flower-shaped structures on the strike-slip fault profile. Positive flower-shaped structures are generally associated with compression-torsion strike-slip faults. Most faults on the upper part of the strike-slip fault have reverse fault throws. Negative flower-shaped structures are generally associated with compression-torsion strike-slip faults. Most faults on the upper part of the strike-slip fault have positive fault throws. The fundamental reason is that the fault strike and strike-slip direction are configured differently, which affects the difference in the structural style of the strike-slip fault profile.

[0004] At present, strike-slip fault simulation devices are mainly used to simulate simple strike-slip, and are unable to quantitatively control the movement angle of the compression-torsion or tension-torsion strike-slip composite movement on the profile. Summary of the invention

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0046] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] In the existing field of geological science research, strike-slip fault simulation devices are mainly used to simulate simple parallel or oblique strike-slip movements. They are unable to quantitatively control the movement angle of compression-torsion or tension-torsion composite strike-slip movements. Therefore, it is difficult to simulate a model that is more in line with the complex actual geological tectonic stress, and it is even more difficult to comprehensively explore the deformation characteristics and formation mechanism of strike-slip faults under the background of composite geological tectonic stress of different degrees and angles.

[0048] In view of the problems of the prior art, the inventors have realized that in the actual crustal movement process, strike-slip and compression movement, strike-slip and extension movement often occur together in a composite form, and in the composite movement dominated by strike-slip movement, different degrees of compression or extension stress components have different effects on the deformation and evolution of strike-slip faults. Therefore, by conducting simulation experiments of strike-slip composite movement at different angles for different degrees of compression or extension stress in the strike-slip composite movement, the comprehensiveness and authenticity of the entire simulation process can be improved. Based on this, when conducting compression-torsion or tension-torsion strike-slip simulation experiments, a detachable angle adjustment member can be added to the experimental device to adjust the angle of the strike-slip movement process, thereby obtaining different crustal movement change data, ensuring that the device can adjust the simulated strike-slip movement angle according to the specific research needs, thereby more accurately simulating the behavior of the fault under different composite geological stress states, so that the device can better meet the simulation requirements of various complex geological structures.

[0049] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0050] Figure 1 This is a schematic diagram of the top view of the physical simulation device for quantitatively controlling the angle of strike-slip motion provided in an embodiment of the present application. Figure 1 As shown, the strike-slip motion simulation device 100 includes:

[0051] at least two plate simulation components and a drive mechanism;

[0052] The driving mechanism is connected to at least two plate simulation components to drive the at least two plate simulation components to perform strike-slip motion.

[0053] That is, the physical simulation device 100 for quantitatively controlling the strike-slip motion angle may include two or more plate simulation components. Figure 1 The strike-slip motion simulation device 100 is only taken as an example to include two plate simulation components (a first plate simulation component and a second plate simulation component).

[0054] Furthermore, each plate simulation component includes a bottom plate. Specifically, the first plate simulation component includes a first bottom plate 101 , and the second plate simulation component includes a second bottom plate 102 .

[0055] Furthermore, each plate simulation component further includes at least one angle adjustment component 103 , that is, the first plate simulation component and the second plate simulation component both include at least one angle adjustment component 103 .

[0056] For each plate simulation component, the bottom plate of the plate simulation component is connected to the driving mechanism; at least one angle adjustment member 103 is detachably mounted on the bottom plate to adjust the strike-slip motion angle of the simulated crust deformation process.

[0057] Among them, the base plate is the basic structure of each plate simulation component, which is placed on the bottom experimental table and connected to the driving mechanism; the angle adjustment member 103 is installed at both ends of the base plate, and its main function is to simulate different strike-slip motion angles. In addition, the angle adjustment member 103 is designed to be detachable and can be easily replaced or adjusted according to different experimental requirements; the driving mechanism is responsible for providing the necessary power to drive the mutual strike-slip movement between the first base plate 101 and the second base plate 102, such as compression-torsion or tension-torsion. The driving mechanism may include an electric motor, a hydraulic system or other mechanical transmission equipment, which can accurately control the magnitude and direction of the force applied to the base plate.

[0058] Specifically, by adjusting the number of angle adjustment members 103, different strike-slip motion angles during crust deformation can be simulated, such as the angle changes of normal faults, reverse faults or strike-slip faults; the application of the driving mechanism enables the plate simulation components to perform mutual dislocation and strike-slip motion under controlled conditions, thereby studying how these forces affect the structure and dynamics of the crust.

[0059] Optionally, the driving mechanism includes a first driving assembly and a second driving assembly, the first driving assembly includes at least two first motion motors 104, and the second driving assembly includes at least two second motion motors 105;

[0060] A first end of each base plate is connected to the first motion motor 104 , and an opposite second end is connected to the second motion motor 105 .

[0061] For example, the physical simulation device 100 for quantitative control of strike-slip motion angle includes two plate simulation components. In this case, the first drive component includes two first motion motors 104, and the second drive component includes two second motion motors 105. One first motion motor 104 of the first drive component is connected to the first end of the first base plate 101, and the other first motion motor 104 is connected to the first end of the second base plate 102; one second motion motor 105 of the second drive component is connected to the second end of the first base plate 101, and the other second motion motor 105 is connected to the second end of the second base plate 102, so as to simulate more complex interaction dynamics between crustal plates.

[0062] Optionally, the physical simulation device 100 for quantitatively controlling the strike-slip motion angle further includes:

[0063] A first guide mechanism 106 and a second guide mechanism 107;

[0064] The first guide mechanism 106 is connected to the first driving assembly, and the second guide mechanism 107 is connected to the second driving assembly.

[0065] Optionally, the first guide mechanism 106 and the second guide mechanism 107 may be arc-shaped tracks, linear tracks, or tracks of other shapes, which are not specifically limited in the embodiment of the present application.

[0066] It should be understood that the guide mechanism can ensure that the force transmission of the driving component is carried out along a preset track path, thereby maintaining the accuracy and consistency of the simulation process, ensuring that the plate simulation component maintains the correct position and direction when subjected to driving force, reducing deviation and friction, and improving the authenticity and effectiveness of the entire simulation.

[0067] Optionally, the physical simulation device 100 for quantitatively controlling the strike-slip motion angle further includes:

[0068] Two baffles 108 placed in parallel;

[0069] At least two plate simulation assemblies and a driving mechanism are disposed between the two baffles 108 .

[0070] Optionally, the two baffles 108 are detachable glass baffles.

[0071] Among them, the two baffles 108 are placed in parallel, and all plate simulation components) and driving mechanisms are arranged between the two baffles 108, which not only provides necessary structural support for the physical simulation device 100 for quantitative control of the strike-slip motion angle, but also protects the internal components from external interference, increases the stability of the entire physical simulation device 100 for quantitative control of the strike-slip motion angle, and ensures that all components can be kept in the correct position during the simulation process; in addition, the baffle 108 is a detachable glass baffle, which provides visual transparency and facilitates the observation and recording of the strike-slip motion phenomenon during the experiment. In addition, the glass material is easy to clean and maintain, and has sufficient strength to support the force of the physical simulation device 100 for quantitative control of the strike-slip motion angle during operation.

[0072] Figure 2 A schematic diagram of the first-perspective stereoscopic structure of an angle adjustment member in a physical simulation device for quantitative control of strike-slip motion angle provided in an embodiment of the present application. Figure 3 A schematic diagram of the second perspective stereoscopic structure of the angle adjustment member in the physical simulation device for quantitative control of strike-slip motion angle provided in an embodiment of the present application. Figure 2 and Figure 3 As shown, the angle adjustment member 103 has a first surface 109 and a second surface 110 which are parallel to each other, and a third surface 111 and a fourth surface 112 which have an angle.

[0073] For example, in the physical simulation device 100 for quantitative control of strike-slip motion angle, the first surface 109 of the angle adjustment member 103 is connected to the bottom plate, and the third surface 111 is connected to the driving mechanism.

[0074] The first surface 109 and the third surface 111 are perpendicular to each other, which ensures that the angle adjustment member 103 can be stable and immobile, thereby improving the simulation accuracy and stability of the physical simulation device 100 for quantitative control of strike-slip motion angle.

[0075] Optionally, at least one angle adjustment member 103 is arranged in parallel in a tip-joined manner.

[0076] The angle adjustment member 103 is designed as a wedge-shaped structure, wherein the first surface 109 and the second surface 110 are parallel to each other, providing a stable support surface and a mounting surface; a specific angle is set between the third surface 111 and the fourth surface 112, and the angle is used to adjust the strike-slip motion angle of the simulated strike-slip motion. For example, if the angle between the third surface 111 and the fourth surface 112 is 5°, and the strike-slip motion angle of the physical simulation experiment of quantitative control of the strike-slip motion angle is 10°, two angle adjustment members 103 are required to complete the physical simulation experiment of quantitative control of the strike-slip motion angle.

[0077] Specifically, the first surface 109 of the angle adjustment member 103 is configured to fit closely with the bottom plate, ensuring that there is a stable fixed relationship between the angle adjustment member 103 and the bottom plate; the third surface 111 is connected to the driving mechanism, and the design of this surface allows the driving force to be directly transmitted to the plate simulation component. During the simulation experiment of the physical simulation device 100 for quantitative control of strike-slip motion angle, the plate simulation component can move under the driving force, ensuring that the bottom plate moves along the trajectory of the first guide mechanism 106 and the second guide mechanism 107, thereby connecting the driving mechanism to the third surface 111 of the angle adjustment member 103. In addition, by increasing or decreasing the number of angle adjustment members 103, it can be ensured that the physical simulation device 100 for quantitative control of strike-slip motion angle can achieve quantitative control of the strike-slip motion angle when conducting a strike-slip motion experiment.

[0078] Specifically, if the angle between the third surface 111 and the fourth surface 112 of the angle adjustment member 103 is 5°, and the angle for simulating strike-slip motion is 10°, then when assembling the physical simulation device 100 for quantitative control of strike-slip motion angle, first remove the two groups of angle adjustment members 103 that are tightly fitted with the driving mechanism to provide strike-slip motion conditions for the driving mechanism to drive the driving simulation component to rotate 10°, and ensure that all angle adjustment members 103 except the two removed angle adjustment members 103 can be tightly spliced ​​to avoid any looseness or deviation during operation.

[0079] Optionally, the third surface 111 of each angle adjustment member 103 is provided with a connection concave point 113, and the fourth surface 112 is provided with a connection convex point 114;

[0080] Adjacent angle adjustment members in at least one angle adjustment member 103 are connected via connection protrusions 114 and connection recesses 113 .

[0081] Among them, multiple angle adjustment members 103 are arranged in parallel in a tip-butted manner, aiming to create a continuous and uniform interface, which has a significant effect on simulating long-distance geological faults and other linear geological structures; specifically, the tip-butted manner means that the ends of the angles of each angle adjustment member 103 are aligned and placed on the same side, and the third surface 111 and the fourth surface 112 between adjacent angle adjustment members are in close contact.

[0082] In addition, one or more connecting recesses 113 are designed on the third surface 111 of each angle adjustment member 103, which are used to receive the connecting protrusions 114 on the fourth surface 112 of the adjacent angle adjustment member, wherein the connecting protrusions 114 arranged on the fourth surface 112 of each angle adjustment member 103 can match the size and shape of the connecting recesses 113, thereby ensuring that each connecting protrusion 114 is physically inserted into the connecting recess 113 of the adjacent adjustment member. In a possible implementation, the connecting protrusions 114 and the connecting recesses 113 can be inverted trapezoidal structures, and the inverted trapezoidal design can make the angle adjustment members 103 more closely spliced ​​... In this way, adjacent angle adjustment members 103 can be connected by simple interlocking means without the need for additional fixing devices, which not only ensures the overall stability of the physical simulation device 100 for quantitative control of the angle of strike-slip motion, but also facilitates rapid assembly and disassembly. Specifically, when assembling these angle adjustment members 103, the connection protrusions 114 of each member can be aligned with the connection recesses 113 of the lower member and lightly pressed to lock them. When the simulation configuration needs to be adjusted or changed, the angle adjustment members 103 can be simply rearranged by unlocking the connection between the connection protrusions 114 and the connection recesses 113.

[0083] Figure 4 This is a schematic diagram of the front view of the physical simulation device for quantitatively controlling the angle of strike-slip motion provided in an embodiment of the present application. Figure 4 As shown, the first bottom plate 101 and the second bottom plate 102 are stably fixed on the bottom plate experimental table, and solid baffles 108 are respectively provided on both sides of the experimental table to limit the diffusion of experimental materials. When conducting simulation experiments, the experimental materials are evenly laid on the upper surfaces of the first bottom plate 101 and the second bottom plate 102, and the two baffles 108 are effectively constrained to ensure that the experimental materials are concentrated in the middle area of ​​the two bottom plates, thereby ensuring the stability of the materials during the experiment and the accuracy of the experimental data.

[0084] Figure 5 The flowchart of the physical simulation method for quantitatively controlling the angle of strike-slip motion provided in the embodiment of the present application is shown in FIG. Figure 5 As shown, the method includes:

[0085] S501, obtaining a target speed, a target direction, and the number of angle adjustment components.

[0086] The execution subject of the embodiment of the present application is an electronic device, which can be a terminal device, such as a laptop, a desktop computer, a tablet computer, etc., or a server. In practical applications, whether the electronic device is a terminal device or a server can be determined according to actual conditions, and no specific limitation is imposed on this.

[0087] It should be understood that the electronic device can be used with Figure 1-Figure 4 The illustrated strike-slip motion angle quantitative control physical simulation device 100 is connected for communication to control the movement of the driving mechanism in the strike-slip motion angle quantitative control physical simulation device 100 .

[0088] The target speed represents the speed of the moving motor during the physical simulation movement of the strike-slip motion angle quantitative control. The target direction is used to specify the moving direction of the moving motor in the physical simulation device 100 for the strike-slip motion angle quantitative control to ensure that the motion trajectory meets the experimental requirements. The number of angle adjustment members 103 determines the size of the strike-slip motion angle during the physical simulation movement of the strike-slip motion angle quantitative control.

[0089] For example, the strike-slip motion angle during the simulation experiment can be precisely and quantitatively controlled by increasing or decreasing the number of angle adjustment members 103 .

[0090] In a possible implementation, a control interface is displayed on a display screen of an electronic device, and the control interface includes multiple controls such as a speed control, a direction control, and a control for the number of angle adjustment parts. The user can operate the above controls according to experimental requirements and input a target speed, a target direction, and the number of angle adjustment parts. Correspondingly, the electronic device obtains the target speed, target direction, and the number of angle adjustment parts input by the user in response to the operation of the above controls.

[0091] Optionally, the type of the above-mentioned control may be a digital input box, a slider, a knob, etc.

[0092] In another possible implementation, the target speed, target direction, and number of angle adjustment components stored in other electronic devices may be obtained, or the target speed, target direction, and number of angle adjustment components sent by other electronic devices may be received.

[0093] Specifically, the driving rate of the driving mechanism can be determined according to the target speed, and the driving direction of the driving mechanism can be determined according to the target direction, that is, the direction of tension or compression can be set.

[0094] Optionally, when the driving mechanism includes multiple motion motors, the identification of the target motion motor may also be obtained.

[0095] S502 . For each number of angle adjustment components, determine the strike-slip motion angle corresponding to the number of angle adjustment components in the physical simulation device 100 for quantitative control of strike-slip motion angle.

[0096] Taking compression-torsion strike-slip motion as an example, compression-torsion refers to the movement angle of the crust under the combined action of compression stress or torsional stress in complex strike-slip motion. For example, during the simulation experiment, the number and angle of the angle adjustment members 103 can be increased or decreased to control the electronic device to generate the corresponding movement angle, thereby simulating the complex geological stress environment during the experiment.

[0097] S503. In response to the user's operation, the driving mechanism in the strike-slip motion quantitative control physical simulation device 100 is controlled to drive at least one plate simulation component to perform strike-slip motion according to the target speed and target direction. In a possible implementation, the driving mechanism in the strike-slip motion quantitative control physical simulation device 100 can be controlled to move according to the target speed and target direction input by the user in the user interface.

[0098] Optionally, a control signal can be generated according to the target speed and target direction, and the control signal can be sent to the driving mechanism to control the driving mechanism to run in accordance with the set target speed and target direction, thereby driving the corresponding plate simulation component to perform strike-slip motion.

[0099] In another possible implementation manner, the target motion motor corresponding to the identifier of the target motion motor may be controlled to move according to the target speed and the target direction.

[0100] For example, if the driving mechanism is a motor, the driving speed of the driving mechanism in the physical simulation device 100 can be quantitatively controlled by controlling the slip angle by adjusting the rotation speed of the motor; if the driving mechanism is a hydraulic system, the driving speed of the driving mechanism can be controlled by changing the pressure of the hydraulic system.

[0101] In addition, during the movement, the speed and position of the plate simulation components can be monitored in real time through sensors to ensure that the movement trajectory meets the preset direction and speed. If there is any deviation, the drive mechanism is automatically adjusted to correct it.

[0102] Specifically, a control signal is generated according to the target speed and direction input by the user, and the control signal is transmitted to the driving mechanism, which then controls and adjusts the first driving component and the second driving component to run in accordance with the set target speed and target direction, thereby driving the corresponding plate simulation component (base plate and angle adjustment member 103) to perform strike-slip motion.

[0103] S504 , collecting strike-slip motion sub-information of the experimental material placed above the two plate simulation components in the physical simulation device 100 for quantitative control of strike-slip motion angle according to a preset frequency.

[0104] Among them, the strike-slip motion sub-information includes the deformation and fracture conditions of the experimental materials under the movement of the plate simulation components.

[0105] During the simulation experiment, use a high-resolution camera or other imaging device to regularly capture images of the surface of the experimental material. This includes: setting the camera to cover the entire experimental area to ensure that there are no blind spots; setting the automatic acquisition frequency, such as once a minute or a frequency that varies according to the experimental stage. Finally, the acquired image data is stored in the device and preliminary image processing is performed, such as cropping, contrast adjustment, etc., to improve the accuracy of subsequent analysis.

[0106] Specifically, according to the needs of the experiment, a suitable data acquisition frequency is preset, for example, once per second or 10 times per minute; then, a high-precision image acquisition system, such as a high-resolution camera or scanner, is configured above the two plate simulation components to capture the surface deformation of the experimental material; image processing software is used to automatically extract deformation data from the continuously or timed captured images, that is, the strike-slip motion sub-information at each strike-slip motion angle. The above multiple strike-slip motion sub-information all reflect the deformation of the experimental material under the influence of different strike-slip motion angles.

[0107] S505. Determine the strike-slip motion information of the experimental material according to the plurality of strike-slip motion sub-information corresponding to different strike-slip motion angles.

[0108] Among them, in the simulation experiment provided in the embodiment of the present application, the strike-slip motion sub-information under different compression-torsion angles is collected by electronic equipment. This information includes the deformation trajectory and fracture conditions of the experimental material under a specific compression-torsion angle, and these strike-slip motion sub-information are compared and comprehensively analyzed to finally determine the strike-slip motion information of the experimental material.

[0109] Specifically, the strike-slip motion sub-information under each compression-torsion angle is first sorted and marked, including the corresponding compression-torsion angle and the deformation data of the experimental material. Then, by comparing the sub-information under different compression-torsion angles, the differences and commonalities between the strike-slip motion sub-information can be found, and the influence of the change of compression-torsion angle on the strike-slip fault and stress distribution can be analyzed. Through comparative analysis, the overall movement information of the experimental material during the entire strike-slip process, that is, the strike-slip motion information, can be determined. This information reflects the geological fracture characteristics and deformation mode of the experimental material under different compression-torsion effects. For example, multiple compression-torsion angles may affect the geometric structure of the strike-slip fault, or lead to different stress concentration areas. By comparing the strike-slip motion sub-information, the influence of these angles on the fault formation process can be accurately analyzed, and experimental reports and data charts can be generated to reveal the evolution law and geometric characteristics of strike-slip faults.

[0110] Figure 6 This is a graph showing the experimental results of the physical simulation motion of the strike-slip motion angle quantitative control provided in the embodiment of the present application. Figure 6 As shown, the embodiment of the present application is Figure 5 Based on the physical simulation method of quantitative control of strike-slip motion angle shown in the figure, an experimental result diagram of physical simulation motion of quantitative control of strike-slip motion angle with a compression and torsion of 10° is provided.

[0111] First, in the experimental process of quantitatively controlling the physical simulation movement of the strike-slip motion angle, the following steps can be included: setting the movement direction, the movement direction setting includes the placement direction of the angle adjustment member 103 and the movement direction of the drive assembly, that is, setting the tension-torsion or compression-torsion strike-slip motion; setting the movement angle, the movement angle setting, that is, disassembling or assembling the angle adjustment member 103; setting the experimental parameters, the experimental parameters include: model scale, sand layer thickness, number of sand layers, or thickness of materials such as mesh soil, motor movement rate (that is, the speed of the first motion motor 104 and the speed of the second motion motor 105); based on the control variable method, under the same material, thickness, number of layers and movement rate and other factors, determine the influence mechanism of the strike-slip movement with different compression-torsion or tension-torsion angles on the formation changes and fault growth and development.

[0112] It should be noted that in the embodiments of the present application, simulation experiments of compression-torsion movement were mainly carried out. The main reason is that the innovation of the present application is to study the influence of the strike-slip movement angle on the formation changes or fault growth and development, that is, the focus is on determining the influence of different compression-torsion angles or tension-torsion angles on the formation changes or fault growth and development.

[0113] Specifically, the angle of the angle adjustment member 103 used in this experiment is 5°. At this time, a strike-slip motion experiment with a compression and torsion of 10° is required, that is, the two angle adjustment members 103 connected to the first base plate 101 in the physical simulation device 100 for quantitative control of the strike-slip motion angle need to be removed, and two plate simulation components are provided in the physical simulation device 100 for quantitative control of the strike-slip motion angle.

[0114] The experimental preparation process includes: placing two bottom plates between the baffles 108 of the experimental table, including a first bottom plate 101 and a second bottom plate 102. The first end of the first bottom plate 101 is connected to a first motion motor 104 of the first drive assembly, and the second end of the first bottom plate 101 is connected to a second motion motor 105 of the second drive assembly. The first end of the second bottom plate 102 is connected to another first motion motor 104 of the first drive assembly, and the second end of the second bottom plate 102 is connected to another second motion motor 105 of the second drive assembly. The model scale of the experimental table is set to 50cm×25cm×3cm, and 3cm thick white quartz sand is laid on the experimental table, and a layer of blue quartz sand is covered on the surface of the white quartz sand as a marking layer.

[0115] The experimental process includes: firstly, setting the motion speed of the driving mechanism connected to the first bottom plate 101 to 0.048 cm / min, and setting the driving mechanism connected to the second bottom plate 102 to be stationary. Then, configuring the image acquisition system, for example, if the image acquisition system is a digital camera, setting the image acquisition system to take a picture of the plane deformation characteristics of the experimental material every 10 seconds.

[0116] According to the experimental results collected by the image acquisition system, the experimental results are analyzed. The specific experimental results include four stages, and the detailed analysis is as follows:

[0117] like Figure 6 As shown in part (a), after the experiment starts, when the first base plate 101 driven by the first motion motor 104 and the second motion motor 105 has a strike-slip amount of 2 cm, slight fractures that are difficult to observe with the naked eye appear on the surface of the sand layer. Specifically, R fractures F1 and F2 first appear in the first and last sections, and no fractures are seen in the middle section.

[0118] like Figure 6 As shown in part (b), when the strike-slip amount of the first base plate 101 driven by the first motion motor 104 and the second motion motor 105 is 4 cm, it can be observed that the segmented distribution of the fault in the first section of the sand layer surface is further widened, and the tail section fault is further widened and presents a segmented distribution phenomenon, and a new R fracture F3 also appears in the middle section. It can be seen that the first and tail section faults have a tendency to become stronger, and the middle section also has fault growth and development.

[0119] like Figure 6 As shown in part (c), when the strike-slip amount of the first base plate 101 driven by the first motion motor 104 and the second motion motor 105 is 6 cm, the first and middle sections of the sand layer surface newly develop strike-slip faults F4 and F5, forming a double middle section R fault F3 with the first section, which further develops into the main displacement zone of the overlapping area. The middle section R fault further develops into the main displacement zone. F2 is connected with the newly developed fault F6 in the tail section, forming a double overlapping area. It can be seen that the growth and development of the faults in the first and middle sections of the model as a whole continues to strengthen, and a small fault also appears in the tail section.

[0120] like Figure 6 As shown in the middle part (d), when the slip amount of the first base plate 101 driven by the first motion motor 104 and the second motion motor 105 is 8 cm, it can be observed that the fault is significantly enhanced, and the double overlapping area formed by the tail section F2 and F6 of the sand layer plane is further expanded. The middle main displacement zones F3 and F4 are connected with the head and tail section fault F5 to form a braided overlapping area.

[0121] Figure 7 This is a slice result diagram of the physical simulation motion of the strike-slip motion angle quantitative control provided in the embodiment of the present application. Figure 7 As shown, in Figure 6 After the simulation experiment shown in the figure is completed, specifically, after the experiment, blue quartz sand is paved and covered with a towel and soaked with water. After 12 hours, slices are made to obtain the slice results. The red solid line represents the developed fault, and the number of the section fault is the same as Figure 6 The numbers of the midplane fractures correspond.

[0122] Among them, section a is located in the middle section of the sand layer, cutting through faults F3 and F4, where the stratum is slightly uplifted under the action of compression and torsion; section b is located in the middle section near the end section, cutting through faults F5 and F4, the uplift is more obvious than section a, and the distance between the two faults is larger, forming a semi-flower-shaped structure; section c is located in the end section of the sand layer, cutting through two faults F1 and F5, and the stratum in the middle of the fault is partially uplifted; section d is located in the end section of the sand layer, cutting through faults F7, F1 and F5, forming a positive flower-shaped structure, close to baffle 108, cutting through three faults, the distance between the faults is smaller than that of section c, and the stratum uplift is also lower.

[0123] Figure 8 This is another experimental result diagram of the physical simulation motion of the quantitative control of the strike-slip motion angle provided in the embodiment of the present application. Figure 8 As shown, the embodiment of the present application is Figure 5 Based on the physical simulation method of quantitative control of strike-slip motion angle shown in the figure, an experimental result diagram of physical simulation motion of quantitative control of strike-slip motion angle with a compression and torsion of 30° is provided.

[0124] Specifically, the angle of the angle adjustment member 103 used in this experiment is 5°. At this time, a strike-slip motion experiment with a compression-torsion of 30° is required. Therefore, 6 angle adjustment members 103 are needed to ensure that the compression-torsion during the experiment is 30°, and two plate simulation components are provided in the physical simulation device 100 for quantitative control of the strike-slip motion angle.

[0125] The steps of the experimental preparation stage and experimental process are the same as Figure 6 The steps of the experimental preparation process shown are consistent with those of the experimental process, and therefore, they are not repeated in this embodiment.

[0126] According to the experimental results collected by the image acquisition system, the experimental results are analyzed. The specific experimental results include four stages, and the detailed analysis is as follows:

[0127] like Figure 8 As shown in (a), after the experiment started, when the first base plate 101, driven by the first motion motor 104 and the second motion motor 105, had a strike-slip amount of 2 cm, no obvious strike-slip fault developed in the tail section of the sand layer plane, while large-area R fracture F1 developed in the middle section and the first section, and two thrust faults Fa and Fb also developed in the tail section.

[0128] like Figure 8 As shown in (b), when the first base plate 101 has a strike-slip amount of 4 cm driven by the first motion motor 104 and the second motion motor 105, it can be observed on the sand layer plane that obvious faults F3 and F4 are developed in the tail section, and the R fracture F1 in the middle section and the first section further grows and connects to form a main displacement zone.

[0129] like Figure 8 As shown in (c), when the strike-slip amount of the first base plate 101 driven by the first motion motor 104 and the second motion motor 105 is 6 cm, the strike-slip fault further develops. In the sand layer plane, the strike-slip faults F1, F2, and F5 in the first, middle, and last sections are interconnected to form a braided overlapping area in the middle section.

[0130] like Figure 8 As shown in (d), when the strike-slip amount of the first base plate 101 driven by the first motion motor 104 and the second motion motor 105 is 8 cm, the strike-slip faults in the first, middle and tail sections of the sand layer surface continue to develop, F1 and F4 merge into a large fault, the degree of rupture increases, the fault activity is obvious, the range of the braided overlapping area in the middle section increases, and a horsetail-like structure is formed in the tail section.

[0131] Fig. 9 This is another slice result diagram of the physical simulation motion of the quantitative control of the strike-slip motion angle provided in the embodiment of the present application. Fig. 9 As shown, in Figure 8 Specifically, after the experiment, the surface was paved with blue quartz sand, covered with a towel and soaked with water. After 12 hours, the surface was sliced. The slice results are shown in the figure. The red solid line represents the developed fault, and the number of the section fault is the same as Figure 8 The plane fractures are numbered accordingly.

[0132] Among them, profile a is located in the middle section of the sand layer, cutting through the double overlapping area formed by the F1 and F5 faults. The surface layer of the stratum here has a large uplift under the action of compression and torsion; profile b is located in the middle section near the tail section, cutting through the faults F1 and F5, and is located at the tail end of the double overlapping area, and the uplift is not obvious compared with profile a; profile c is located in the tail section of the sand layer, cutting through three faults, namely F1, F3 and F6, and the strata on both sides of the middle fault are uplifted, forming a positive flower-shaped structure; profile d is located in the tail section of the sand layer near the baffle, cutting through the four faults F1, F3, F6 and F7, showing a positive flower-shaped structure, and the stratum is obviously uplifted.

[0133] Will Figure 6 The experimental results shown and Figure 8The experimental results shown in the figure are compared and analyzed. The premise variable for the comparison is the angle of compression and torsion, which is 10° for the former and 30° for the latter. When the strike-slip amount is 2-4 cm, the strike-slip faults in the former are not obviously developed, and only a small number of strike-slip faults are distributed and developed at the head and tail ends; the latter develops large-scale strike-slip faults and forms the main displacement zone earlier, while the former does not develop the main displacement zone until the strike-slip amount reaches 6 cm. When the strike-slip amount reaches 8 cm, both of them develop positive flower-shaped structures, but the latter has a larger range of positive flower-shaped structures than the former, and the stratum is uplifted higher. In summary, the latter has developed large-scale segmented faults when the strike-slip amount is smaller than the former.

[0134] Fig.10 This is a three-dimensional experimental result diagram of the physical simulation movement of the quantitative control of the strike-slip motion angle provided in the embodiment of the present application when the compression-torsion strike-slip amount is 8 cm. Fig.10 As shown in the figure, the variable is the strike-slip angle of the bottom plate during compression-torsion movement, where the strike-slip angle of A is 10° and that of B is 30°. When the strike-slip amount is 2-4 cm, the strike-slip faults of the former are not obvious, and only a small number of strike-slip faults are distributed and developed at the head and tail ends; the latter develops large-scale strike-slip faults and forms the main displacement zone earlier, while the former does not develop the main displacement zone until the strike-slip amount reaches 6 cm. Compared with the former, the latter has developed large-scale segmented faults when the strike-slip amount is small.

[0135] Specifically, when the compression-torsion slip reached 8 cm during the experiment, 3D scanning imaging was performed on the quartz sand at 10° and 30°, respectively.

[0136] like Fig.10 As shown in part A, when the compression-torsion strike-slip amount reaches 8 cm, the surface of the quartz sand with a strike-slip angle of 10° mainly presents a hill-like micro-uplift with an uplift height between 0 and 2 mm, and the maximum uplift height of the formation can reach 4 mm.

[0137] like Fig.10 As shown in the middle part B, when the compression-torsion slip reaches 8 cm, the surface uplift of the quartz sand with a strike-slip angle of 30° is higher than the former, the uplift height is generally higher than 2 mm, the width is wider, and the maximum surface uplift height can exceed 6 mm.

[0138] It can be seen that when the amount of compression-torsion slip is consistent, a larger initial compression-torsion angle component has a stronger influence on the final experimental results of fracture and geomorphic deformation.
