DETAILED DESCRIPTION

[0026] This application is based on the inventor's discovery and understanding of the following facts and problems:

[0027] Physical simulation experiments are an important method to study the disaster-causing process of fault activity.

[0028] The fault activity disaster-causing process simulation system under different activity modes in the related technology can only simulate the fault activity form in a single direction, and it is difficult to simulate the fault disaster-causing process under different fault activity forms and their combined working conditions.

[0029] Some fault activity simulation systems in the related art are mainly used to simulate fault activities at different inclination angles, but they can only simulate at a single angle each time and cannot simulate fault activities with continuously changing inclination angles.

[0030] The fault activity simulation system in the related art is a closed structure, making it difficult to observe the fault activity process.

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The following describes a system 1 for simulating the disaster-causing process of fault activity under different activity modes according to an embodiment of the present invention with reference to the accompanying drawings.

[0035] like Figure 1-Figure 6 As shown, the system 1 for simulating the disaster-causing process of fracture activity under different activity modes according to an embodiment of the present invention includes a base, a plurality of lifting electric servo jacks 10, a lower movable plate 20, an upper movable plate 30, a test box 40, a front and rear drive device 50 and a left and right drive device 60 (the up and down, left and right and front and back directions are shown by the arrows in the figure).

[0036] Specifically, the base 10 may be a hardened ground or a separately provided base.

[0037] The lifting electric servo jack 10 is arranged on the base, and a plurality of lifting electric servo jacks 10 are arranged at intervals in the horizontal direction.

[0038] The lower movable plate 20 is supported on a plurality of lifting electric servo jacks 10 in a manner that the lower movable plate 20 can be lifted and lowered. The upper movable plate 30 is arranged on the lower movable plate 20 in a manner that the upper movable plate 30 can be slidably disposed forward and backward.

[0039] The test box 40 is suitable for filling the test soil mix material. The test box 40 includes a fixed section 41, a movable section 42 and a flexible transition section (not shown in the figure). The fixed section 41 is arranged on the base, and the movable section 42 can be slid left and right on the upper movable plate 30. The flexible transition section is located between the fixed section 41 and the movable section 42 and connects the fixed section 41 and the movable section 42. The fixed section 41 is located in front of the movable section 42.

[0040] Specifically, "test soil mix material" refers to the material constituting the test soil model, and the technicians in this field can adjust its composition and mix ratio according to actual needs. The fixed section 41 is arranged on the base through a bracket and is separated from the base. The flexible transition section enables the movable section 42 to move in all directions relative to the fixed section 41.

[0041] The front-rear driving device 50 is suitable for driving the movable section 42 to move forward and backward. The left-right driving device 60 is suitable for driving the movable section 42 to move left-right.

[0042] Specifically, the plurality of lifting electric servo jacks 10 can be lifted independently or synchronously. When lifting independently, the tilt angle of the movable section 42 can be adjusted by adjusting the lifting speed and / or amplitude of different lifting electric servo jacks 10 .

[0043] During the test, the prepared test soil mix material is transferred to the test box 40, and the moving speed and amplitude of multiple lifting electric servo jacks 10 are adjusted to simulate the up and down movement of the fault; the front and rear drive device 50 and / or the left and right drive device 60 drives the movable section 42 to move left and right or front and back to simulate the left and right or front and back movement of the fault, thereby realizing the simulation of a single fault activity mode or a combination of multiple fault activity modes to obtain experimental data.

[0044] According to the system 1 for simulating the disaster-causing process of fault activity under different activity modes of the embodiment of the present invention, by setting the lifting electric servo jack 10, the front and rear drive device 50 and the left and right drive device 60, the movable section 42 can be driven in the up-down, left-right and front-back directions, so that the test soil proportion material in the movable section 42 moves relative to the test soil proportion material in the fixed section 41. Compared with the simulation system in the related art that can only simulate a single form of fault activity, the system 1 for simulating the disaster-causing process of fault activity under different activity modes can not only simulate a single form of fault activity in a single direction, but also simulate a combined direction and a combined type of fault activity, and simulate multiple forms of fault activities and multiple combinations of fault activities in different directions and types, so that the functions of the system 1 for simulating the disaster-causing process of fault activity under different activity modes are more flexible and rich, and the applicability of the system 1 for simulating the disaster-causing process of fault activity under different activity modes is improved. For example, normal fault activity, tension activity, and strike-slip activity can also simulate two-dimensional and three-dimensional fault activities.

[0045] Furthermore, by setting a plurality of lifting electric servo jacks 10, front and rear drive devices 50 and left and right drive devices 60, the movement speed and amplitude of the plurality of lifting electric servo jacks 10, front and rear drive devices 50 and left and right drive devices 60 can be independently controlled, not only the movement angle of the movable section 42 can be adjusted, but also the inclination angle of the movable section 42 can be continuously variable during the simulation process, thereby realizing the simulation of fault activity under the condition of continuous change of the fault inclination angle, further enriching the test function of the fault activity disaster process simulation system 1 under different activity modes, and improving the applicability of the fault activity disaster process simulation system 1 under different activity modes.

[0046] Therefore, the fault activity disaster process simulation system 1 under different activity modes according to the embodiment of the present invention can simulate the fault disaster process under different fault activity forms and their combined working conditions, and has the advantages of rich functions and strong applicability.

[0047] The following describes a system 1 for simulating the disaster-causing process of fault activity under different activity modes according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0048] In some specific embodiments of the present invention, Figure 1-Figure 6 As shown, the system 1 for simulating the disaster-causing process of fracture activity under different activity modes according to an embodiment of the present invention includes a base, multiple lifting electric servo jacks 10, a lower movable plate 20, an upper movable plate 30, a test box 40, a front and rear drive device 50 and a left and right drive device 60.

[0049] Specifically, Figure 3 , Figure 4 and Figure 6 As shown, the upper movable plate 30 includes an upper movable plate 30 and a plurality of upper rollers 32, the plurality of upper rollers 32 are rotatably disposed in an upper frame 31, the plurality of upper rollers 32 are all oriented in the front-to-back direction and are arranged in parallel and spaced in the left-to-right direction, and the lower movable plate 20 includes a lower frame 21 and a plurality of lower rollers 22, the plurality of lower rollers 22 are rotatably disposed in the lower frame 21, the plurality of lower rollers 22 are all oriented in the left-to-right direction and are arranged in parallel and spaced in the front-to-back direction. In this way, rolling friction can be formed between the lower movable plate 20 and the upper movable plate 30, and rolling friction can be formed between the movable segment 42 and the upper movable plate 30, thereby reducing the resistance of the movable segment 42 when it moves, and facilitating the movable segment 42 to move so as to simulate the fracture activity.

[0050] More advantageously, if Figure 3 and Figure 4 As shown, the fracture activity disaster process simulation system 1 under different activity modes also includes a plurality of rear limit bars 71, a plurality of left limit bars 72 and a plurality of right limit bars 73. The rear limit bar 71 is connected to the rear surface of the upper movable plate 30 and stops the rear surface of the movable segment 42. The left limit bar 72 is connected to the left side surface of the lower movable plate 20 and stops the left side surface of the upper movable plate 30. The right limit bar 73 is connected to the right side surface of the lower movable plate 20 and stops the right side surface of the upper movable plate 30. The plurality of rear limit bars 71 are arranged at intervals along the left-right direction, the plurality of left limit bars 72 are arranged at intervals along the front-back direction, and the plurality of right limit bars 73 are arranged at intervals along the front-back direction. In this way, the limit bars can be used to limit the movement of the upper movable plate 30 and the test box 40. On the one hand, the movement direction of the upper movable plate 30 and the movable segment 42 can be constrained. On the other hand, the upper movable plate 30 and the movable segment 42 can be prevented from slipping, thereby improving the reliability of the movable segment 42 when moving.

[0051] Alternatively, if Figure 1 and Figure 2 As shown, the left and right drive devices 60 and the front and rear drive devices 50 are hydraulic jacks. This ensures that the front and rear drive devices 50 and the left and right drive devices 60 can provide sufficient driving force to facilitate driving the movable section 42 and simulating a large soil model.

[0052] Specifically, the left and right drive devices 60 and the front and rear drive devices 50 may be provided with micrometers to monitor the displacement.

[0053] Specifically, Figure 1 and Figure 2 As shown, the base is provided with left and right reaction seats 61 and front and rear reaction seats 51, one end of the left and right driving device 60 is connected to the left and right reaction seats 61 and the other end is connected to the movable section 42, and one end of the front and rear driving device 50 is connected to the front and rear reaction seats 51 and the other end is connected to the movable section 42. In this way, the left and right reaction seats 61 and the front and rear reaction seats 51 can be used to provide reaction force, so as to facilitate driving the movable section 42.

[0054] More specifically, one end of the left-right driving device 60 is detachably connected to the left-right reaction seat 61 and the other end is detachably connected to the movable segment 42, and one end of the front-back driving device 50 is detachably connected to the front-back reaction seat 51 and the other end is detachably connected to the movable segment 42. Specifically, when driving in the left-right direction, the left-right driving device 60 is installed and connected with the left-right reaction seat 61 and the movable segment 42, and the front-back driving device 50 is removed; when driving in the front-back direction, the front-back driving device 50 is installed and connected with the front-back reaction seat 51 and the movable segment 42, and the left-right driving device 60 is removed. In this way, the movable segment 42 can be prevented from being restricted by the front-back driving device 50 when driving in the left-right direction, the movable segment 42 can be prevented from being restricted by the left-right driving device 60 when driving in the front-back direction, and the left-right driving device 60 and the front-back driving device 50 can be prevented from interfering with each other.

[0055] Specifically, the front and rear drive device 50 and the left and right drive device 60 are electrically connected to a horizontal drive control device 80 , and the horizontal drive control device 80 is used to control the driving of the left and right drive device 60 and the front and rear drive device 50 .

[0056] Figure 5 A system 1 for simulating the disaster-causing process of fault activity under different activity modes according to some examples of the present invention is shown. Figure 5As shown, the system 1 for simulating the disaster-causing process of fracture activity under different activity modes also includes a lifting control device 11, and multiple lifting electric servo jacks 10 are electrically connected to the lifting control device 11. The lifting control device 11 can be switched between a synchronous state and an independent state. The lifting control device 11 synchronously controls multiple lifting electric servo jacks 10 in the synchronous state and independently controls each lifting electric servo jack 10 in the independent state. In this way, it is convenient to control multiple lifting electric servo jacks 10, so that the movable section 42 can not only be lifted and lowered at a fixed angle, but also the angle can be continuously changed during the lifting process, thereby simulating different types of fracture activity modes, and further improving the functionality and flexibility of the system 1 for simulating the disaster-causing process of fracture activity under different activity modes.

[0057] Optionally, the side wall of the test box 40 is made of transparent acrylic material and a bearing bracket is provided on the outer surface of the side wall, so that the fracture activity process of the test soil mix material in the test box 40 can be observed intuitively and the structural strength and stability of the test box 40 can be ensured by the bearing bracket.

[0058] Advantageously, the fault activity disaster-causing process simulation system 1 under different activity modes also includes an image acquisition device, which is suitable for acquiring images of the test soil mix material. Specifically, the displacement and deformation data of the test soil mix material can be analyzed through the images acquired by the image acquisition device. This makes it easy to collect and record the test process and to study and analyze the test process.

[0059] Furthermore, if Figure 1 and Figure 2 As shown, the fault activity disaster process simulation system 1 under different activity modes also includes a gantry crane 90, which is movably arranged on the base. In this way, the gantry crane 90 can be used to transfer the test soil mix material to the test box 40, saving manpower.

[0060] According to the embodiment of the present invention, the fault activity disaster-causing process simulation system 1 under different activity modes can simulate the normal fault activity, tension activity and slip activity of the fault by controlling the activities of the front and rear drive device 50, the left and right drive device 60 and the lifting electric servo jack 10, and can also simulate the two-dimensional activity and three-dimensional activity of the fault. By adjusting the movement speed of the lifting electric servo jack 10, the front and rear drive device 50 and the left and right drive device 60, the inclination angle of the fault can be continuously variable during the fault simulation process. The transparent acrylic plate of the test box 40 realizes the visualization of the formation mechanism of the ground fissure formed by the fault.

[0061] Other structures and operations of the system 1 for simulating the disaster-causing process of fault activity under different activity modes according to the embodiment of the present invention are known to ordinary technicians in the field and will not be described in detail here.
